If anyone knows about the process of uptake of molasses and the benefits of using it, I would love to know. I've read that ''its the shit'' many a time, but nobody goes into detail, any experts out there?!
Anyone out there with info on Molasses?

It has 2 be UNSULPHERED Molasses you can get it in Wal-mart by the pancake syrup, i picked up a 12 o.z. jar for $2.50. 1 tsp. per gallon. i started using this method myself this week and my plants love it. the idea is so the plant absorbs the extra sugar increasing the bud size ive read by up to 40%. obviously no one can say for sure how much bigger they'll get but it definatly doesnt hurt. ive talked 2 growers that even say that it can mask that "skunky" smell and make it a little more coffee like which is nice if your growing indoors. ive been taking weekly photos and posting them here, if you like follow my thread for the next few weeks,and check my progress and decide 4 yourself.

“Molasses and Plant Carbohydrates”
Sugars relating to plant functions for maximum economic
production
Printed by permission of Texas Plant & Soil Lab, Inc.
ENVIRONMENTAL FACTORS that affect when and how much sugar to use:
a. How much nitrate is in the soil, and plant sap (petiole test).
b. Soil moisture conditions.
c. Sunlight intensity.
d. Temperature.
e. Wind
f. Fruiting stage / load
g. Growth / vigor [shade lower leaves]
The right amount at the right time can improve fruiting and produce normal
plant growth with less attraction for disease and insects.
Needed for healthy plants - fruit production - plant development &
maturity.
Roots take nutrients from the soil and transport them up the stalk thru the
petiole (stem) to the leaves where the sunlight aids the production of
photosynthates (sugars are not the ONLY product of photosynthesis)
carbohydrates (C, H & O), principally glucose (C6H12O6) and then other sugars
and photosynthates are formed.
Plant Sugars and other photosynthates are first translocated (boron is
essential to the translocation) to a fruiting site. If fruit is not available, the
sugars, along with excess nitrates, spur the rapid vegetative growth of the plant
at the expense of creating fruiting bodies (first sink) for the storage of the sugars.
Once the proper balance of environmental factors (heat units, light intensity, soil
moisture, nutrient balance, etc) are met, the fruiting buds form and then fruit
formation gets the first crack at the sugar supply.
Any excess sugars are then translocated to the number two sink, (growing
terminals,) to speed their growth.
The left-over sugars, etc. then go to the number 3 sink, (the roots,) to aid their growth. Here the new root hairs take up nutrients to help continue the cycle of sugar and other photosynthate produc-
tion, fruiting, growth of terminals and roots.
ADDED SUGARS CAN AID THE PLANT IN SEVERAL WAYS:
-
MOLASSES is probably the best outside source of many sugars, such as table
sugar, corn syrup and several more complex sugars such as polysaccharides
found in humus products.
- Sugar can be added to the soil in irrigation water, drip & pivot being the most
effective.
* In the soil it can:
- Feed microbes to stimulate the conversion of nitrates to the more
efficient NH2 form of N to synthesize protein more directly by the plants.
- The roots can directly absorb some of the sugars into the sap stream to
supplement the leaf supply to fruit where it is most needed, and ALSO directly
feed the roots for continued productive growth.
- This ADDED sugar can also help initiate fruiting buds in a steady-slow
fashion while maintaining normal growth.
-EXCESSIVE amounts of ADDED SUGARS applied foliarly can shock the
plant resulting in shortened growth internodes, increased leaf maturity & initiation
of excess fruiting sites.
This can be a short term effect lasting only a few days. Pollination, soil moisture, nutrient balance and sufficiency as well as adequate light for photosynthate production decide how much of the
induced fruit can mature.

im just saying weed isnt a fruit and i dont know one mega grower that uses it. to determine if it works for you u would have to have two grows everything the same but one with molasses and one with out. i never tried that so i dont know for sure but the better you get at growing the less you need to mess around with the unknown you get more experience and your plants yeild more every time till you get them to their max potential. i lost count of how many grows ive had so i cant tell you how long it takes. everyone is diffrent but is still say dont waist your time. especially in hydro it makes a mess, and i started two weeks into flower with the molasses. not to say if someone likes to use it go ahead just my opinion been growing for 8 years. and since fruit is mostly sugar i bet it would work great on your apple trees

There are certain things, certain functions, certain processes in just about all plant life that is universal and in other things it can still work very much the same way but for a different purpose.
That means if something does something positive for a plant type it is highly likely that for most similar plants types a roughly equal reaction could be expected and then in other types of plants with the same functions or similar functions a similar but possibly to a differing degree result could also be expected.
　
Molasses has a known NPK value, it is part of the mixture of some fertilizers. It is known to work.
　
When it comes to fruit plants/trees and budding plants/trees there are similarities in needs and to a degree function so just because something is proven on fruit plants does not mean it has no bearing at all on flowering plants.
As I said, similar functions and similar needs means a reaction from the same things but possibly to a differing degree, but still a positive reaction.
　
I have four family members with degrees in botany, two of which used to partake in the sort of activity we are discussing, and in general they all agree that molasses helps/works.
Then of course it breaks down into a well what kind of plant because they can have different needs and varying needs at different stages of growth and what are the growing conditions like and the climate conditions like, is the plant being grown in its natural environment, more or less and not something that is way out of its normal range, and will there be any other nutrients used and if so what kind/types and in what amounts etc., etc., etc . but in general they agree it helps/works.
oh really???

Sweet Goodness - Magical Molasses
There are a number of different nutrient and fertilizer companies selling a variety of additives billed as carbohydrate booster products for plants. Usually retailing for tens of dollars per gallon if not tens of dollars per liter, these products usually claim to work as a carbohydrate source for plants. A variety of benefits are supposed to be unlocked by the use of these products, including the relief of plant stresses and increases in the rate of nutrient uptake. On the surface it sounds real good, and while these kinds of products almost always base their claims in enough science to sound good, reality doesn’t always live up to the hype.
The 3LB are pretty well known for our distrust of nutrient companies like Advanced Nutrients who produce large lines of products (usually with large accompanying price tags) claiming to be a series of “magic bullets” - unlocking the keys to growing success for new and experienced growers alike. One member of the three_little_birds grower’s and breeder’s collective decided to sample one of these products a while back, intending to give the product a fair trial and then report on the results to the community at Cannabis World.
Imagine, if you will, Tweetie bird flying off to the local hydroponics store, purchasing a bottle of the wonder product - “Super Plant Carb!” (not it’s real name) - and then dragging it back to the bird’s nest. With a sense of expectation our lil’ bird opens the lid, hoping to take a peek and a whiff of this new (and expensive) goodie for our wonderful plants. She is greeted with a familiar sweet smell that it takes a moment to place. Then the realization hits her. . .
Molasses! The “Super Plant Carb!” smells just like Blackstrap Molasses. At the thought that she’s just paid something like $15 for a liter of molasses, our Tweetie bird scowls. Surely she tells herself there must be more to this product than just molasses. So she dips a wing into the sweet juice ever so slightly, and brings it up to have a taste.
Much the same way a sneaky Sylvester cat is exposed by a little yellow bird saying - “I thought I saw a puddy tat . . . I did I did see a puddy tat . . . and he’s standing right there!” - our Tweetie bird had discovered the essence of this product. It was indeed nothing more than Blackstrap Molasses, a quick taste had conformed for our Tweetie bird that she had wasted her time and effort lugging home a very expensive bottle of plant food additive. Molasses is something we already use for gardening at the Bird’s Nest. In fact sweeteners like molasses have long been a part of the arsenal of common products used by organic gardeners to bring greater health to their soils and plants.
So please listen to the little yellow bird when she chirps, because our Tweetie bird knows her stuff. The fertilizer companies are like the bumbling Sylvester in many ways, but rather than picturing themselves stuffed with a little bird, they see themselves growing fat with huge profits from the wallets of unsuspecting consumers. Let us assure you it’s not the vision of yellow feathers floating in front of their stuffed mouths that led these executives in their attempt to “pounce” on the plant growing public.
And the repackaging of molasses as plant food or plant additive is not just limited to the companies selling their products in hydroponic stores. Folks shopping at places like Wal-Mart are just as likely to be taken in by this tactic. In this particular case the offending party is Schultz® Garden Safe All Purpose Liquid Plant Food 3-1-5. This is a relatively inexpensive product that seems appealing to a variety of organic gardeners. Here’s Shultz own description of their product.
“Garden Safe Liquid Plant Foods are made from plants in a patented technology that provides plants with essential nutrients for beautiful flowers and foliage and no offensive smell. Plus they improve soils by enhancing natural microbial activity. Great for all vegetables, herbs, flowers, trees, shrubs and houseplants including roses, tomatoes, fruits, and lawns. Derived from completely natural ingredients, Garden Safe All Purpose Liquid Plant Food feeds plants and invigorates soil microbial activity. Made from sugar beet roots! No offensive manure or fish odors.”
That sure sounds good, and the three_little_birds will even go as far as to say we agree 100% with all the claims made in that little blurb of ad copy. But here’s the problem, Shultz isn’t exactly telling the public that the bottle of “fertilizer” they are buying is nothing more than a waste product derived from the production of sugar. In fact, Schultz® Garden Safe 3-1-5 Liquid Plant Food is really and truly nothing more than a form molasses derived from sugar beet processing that is usually used as an animal feed sweetener. If you don’t believe a band of birds, go ahead and look for yourself at the fine print on a Garden Safe bottle where it says - “Contains 3.0% Water Soluble Nitrogen, 1.0% Available Phosphate, 5.0% Soluble Potash - derived from molasses.”
The only problem we see, is that animal feed additives shouldn’t be retailing for $7.95 a quart, and that’s the price Shultz is charging for it’s Garden Safe product. While we don’t find that quite as offensive as Advanced Nutrients selling their “CarboLoad” product for $14.00 a liter, we still know that it’s terribly overpriced for sugar processing wastes. So, just as our band of birds gave the scoop on poop in our Guano Guide, we’re now about to give folks the sweet truth about molasses.
What Is The Story Behind This Sweet Sticky Garden Goodness?
Molasses is a syrupy, thick juice created by the processing of either sugar beets or the sugar cane plant. Depending on the definition used, Sweet Sorghum also qualifies as a molasses, although technically it’s a thickened syrup more akin to Maple Syrup than to molasses. The grade and type of molasses depends on the maturity of the sugar cane or beet and the method of extraction. The different molasses’ have names like: first molasses, second molasses, unsulphured molasses, sulphured molasses, and blackstrap molasses. For gardeners the sweet syrup can work as a carbohydrate source to feed and stimulate microorganisms. And, because molasses (average NPK 1-0-5) contains potash, sulfur, and many trace minerals, it can serve as a nutritious soil amendment. Molasses is also an excellent chelating agent.
Several grades and types of molasses are produced by sugar cane processing. First the plants are harvested and stripped of their leaves, and then the sugar cane is usually crushed or mashed to extract it’s sugary juice. Sugar manufacturing begins by boiling cane juice until it reaches the proper consistency, it is then processed to extract sugar. This first boiling and processing produces what is called first molasses, this has the highest sugar content of the molasses because relatively little sugar has been extracted from the juice. Green (unripe) sugar cane that has been treated with sulphur fumes during sugar extraction produces sulphured molasses. The juice of sun-ripened cane which has been clarified and concentrated produces unsulphured molasses. Another boiling and sugar extraction produces second molasses which has a slight bitter tinge to its taste.
Further rounds of processing and boiling yield dark colored blackstrap molasses, which is the most nutritionally valuable of the various types of molasses. It is commonly used as a sweetner in the manufacture of cattle and other animal feeds, and is even sold as a human health supplement. Any kind of molasses will work to provide benefit for soil and growing plants, but blackstrap molasses is the best choice because it contains the greatest concentration of sulfur, iron and micronutrients from the original cane material. Dry molasses is something different still. It’s not exactly just dried molasses either, it’s molasses sprayed on grain residue which acts as a “carrier”.
Molasses production is a bit different when it comes to the sugar beet. You might say “bird’s know beets” because one of our flock grew up near Canada’s “sugar beet capitol” in Alberta. Their family worked side by side with migrant workers tending the beet fields. The work consisted of weeding and thinning by hand, culling the thinner and weaker plants to leave behind the best beets. After the growing season and several hard frosts - which increase the sugar content - the beets are harvested by machines, piled on trucks and delivered to their destination.
At harvest time, a huge pile of beets will begin to build up outside of the sugar factory that will eventually dwarf the factory itself in size. Gradually throughout the winter the pile will diminish as the whole beets are ground into a mash and then cooked. The cooking serves to reduce and clarify the beet mash, releasing huge columns of stinky (but harmless) beet steam into the air. Sometimes, if the air is cold enough, the steam will fall to the ground around the factory as snow!
As we’ve already learned, in the of sugar cane the consecutive rounds of sugar manufacturing produce first molasses and second molasses. With the humble sugar beet, the intermediate syrups get names like high green and low green, it’s only the syrup left after the final stage of sugar extraction that is called molasses. After final processing, the leftover sugar beet mash is dried then combined with the thick black colored molasses to serve as fodder for cattle. Sugar beet molasses is also used to sweeten feed for horses, sheep, chickens, etc.
Sugar beet molasses is only considered useful as an animal feed additive because it has fairly high concentrations of many salts including calcium, potassium, oxalate, and chloride. Despite the fact that it’s not suitable for human consumption and some consider it to be an industrial waste or industrial by-product, molasses produced from sugar beets makes a wonderful plant fertilizer. While humans may reject beet molasses due to the various “extras” the sugar beet brings to the table, to our plant’s it’s a different story. Sugar beet molasses is usually fairly chemical free as well, at least in our experience. Although farmers generally fertilize their fields in the spring using the various arrays of available fertilizers, weed chemicals (herbicides) are not used for this crop due to the beet plant’s relatively delicate nature.
There is at least one other type of “molasses” we are aware of, and that would be sorghum molasses. It’s made from a plant known as sweet sorghum or sorghum cane in treatments somewhat similar to sugar beets and/or sugar cane processing. If our understanding is correct, sorghum molasses is more correctly called a thickened syrup rather than a by-product of sugar production. So in our eyes sorghum molasses is probably more like Maple Syrup than a true molasses.
In the distant past sorghum syrup was a common locally produced sweetener in many areas, but today it is fairly rare speciality product that could get fairly pricey compared to Molasses. Because sorghum molasses is the final product of sweet sorghum processing, and blackstrap and sugar beet molasses are simply waste by-products of sugar manufacturing, it’s pretty easy to understand the difference in expense between the products. The word from the birds is - there isn’t any apparent advantage to justify the extra expense of using sorghum molasses as a substitute for blackstrap or sugar beet molasses in the garden. So if you find sorghum molasses, instead of using it in your garden, you’ll probably want to use it as an alternate sweetener on some biscuits.
That’s a quick bird’s eye look at the differences between the various types and grades of molasses and how they are produced. Now it’s time to get a peek at the why’s and how’s of using molasses in gardening.
Why Molasses?
The reason nutrient manufacturer’s have “discovered” molasses is the simple fact that it’s a great source of carbohydrates to stimulate the growth of beneficial microorganisms. “Carbohydrate” is really just a fancy word for sugar, and molasses is the best sugar for horticultural use. Folks who have read some of our prior essays know that we are big fans of promoting and nourishing soil life, and that we attribute a good portion of our growing success to the attention we pay to building a thriving “micro-herd” to work in concert with plant roots to digest and assimilate nutrients. We really do buy into the old organic gardening adage - “Feed the soil not the plant.”
Molasses is a good, quick source of energy for the various forms of microbes and soil life in a compost pile or good living soil. As we said earlier, molasses is a carbon source that feeds the beneficial microbes that create greater natural soil fertility. But, if giving a sugar boost was the only goal, there would be lot’s of alternatives. We could even go with the old Milly Blunt story of using Coke on plants as a child, after all Coke would be a great source of sugar to feed microbes and it also contains phosphoric acid to provide phosphorus for strengthening roots and encouraging blooming. In our eyes though, the primary thing that makes molasses the best sugar for agricultural use is it’s trace minerals.
In addition to sugars, molasses contains significant amounts of potash, sulfur, and a variety of micronutrients. Because molasses is derived from plants, and because the manufacturing processes that create it remove mostly sugars, the majority of the mineral nutrients that were contained in the original sugar cane or sugar beet are still present in molasses. This is a critical factor because a balanced supply of mineral nutrients is essential for those “beneficial beasties” to survive and thrive. That’s one of the secrets we’ve discovered to really successful organic gardening, the micronutrients found in organic amendments like molasses, kelp, and alfalfa were all derived from other plant sources and are quickly and easily available to our soil and plants. This is especially important for the soil “micro-herd” of critters who depend on tiny amounts of those trace minerals as catalysts to make the enzymes that create biochemical transformations. That last sentence was our fancy way of saying - it’s actually the critters in “live soil” that break down organic fertilizers and “feed” it to our plants.
One final benefit molasses can provide to your garden is it’s ability to work as a chelating agent. That’s a scientific way of saying that molasses is one of those “magical” substances that can convert some chemical nutrients into a form that’s easily available for critters and plants. Chelated minerals can be absorbed directly and remain available and stable in the soil. Rather than spend a lot of time and effort explaining the relationships between chelates and micronutrients, we are going to quote one of our favorite sources for explaining soil for scientific laymen.
“Micronutrients occur, in cells as well as in soil, as part of large, complex organic molecules in chelated form. The word chelate (pronounced “KEE-late”
comes from the Greek word for “claw,” which indicates how a single nutrient ion is held in the center of the larger molecule. The finely balanced interactions between micronutrients are complex and not fully understood. We do know that balance is crucial; any micronutrient, when present in excessive amounts, will become a poison, and certain poisonous elements, such as chlorine are also essential micronutrients.
For this reason natural, organic sources of micronutrients are the best means of supplying them to the soil; they are present in balanced quantities and not liable to be over applied through error or ignorance. When used in naturally chelated form, excess micronutrients will be locked up and prevented from disrupting soil balance.”
Excerpted from “The Soul of Soil”
by Grace Gershuny and Joe Smillie
That’s not advertising hype either, no product being sold there. That’s just the words of a pair of authors who have spent their lives studying, building, and nurturing soils.
Molasses’ ability to act as a chelate explains it’s presence in organic stimulant products like Earth Juice Catalyst. Chelates are known for their ability to unlock the potential of fertilizers, and some smart biological farmers we know are using chelating agents (like Humic Acid) to allow them to make dramatic cuts in normal levels of fertilizer application.
One way to observe this reaction at work would be to mix up a solution of one part molasses to nine parts water and then soak an object which is coated with iron rust (like a simple nail for instance) in that solution for two weeks. The chelating action of the molasses will remove the mineral elements of the rust and hold them in that “claw shaped” molecule that Grace and Joe just described.
As we’ve commented on elsewhere, it’s not always possible to find good information about the fertilizer benefits of some products that aren’t necessarily produced as plant food. But we’ve also found that by taking a careful look at nutritional information provided for products like molasses that can be consumed by humans, we can get a pretty decent look at the nutrition we can expect a plant to get as well.
There are many brand’s of molasses available, so please do not look at our use of a particular brand as an endorsement, our choice of Brer Rabbit molasses as an example is simply due to our familiarity with the product, one of our Grandmother’s preferred this brand.

Dry molasses is something different still. It’s not exactly just dried molasses either, it’s molasses sprayed on grain residue which acts as a “carrier”.
Molasses production is a bit different when it comes to the sugar beet. You might say “bird’s know beets” because one of our flock grew up near Canada’s “sugar beet capitol” in Alberta. Their family worked side by side with migrant workers tending the beet fields. The work consisted of weeding and thinning by hand, culling the thinner and weaker plants to leave behind the best beets. After the growing season and several hard frosts - which increase the sugar content - the beets are harvested by machines, piled on trucks and delivered to their destination.
At harvest time, a huge pile of beets will begin to build up outside of the sugar factory that will eventually dwarf the factory itself in size. Gradually throughout the winter the pile will diminish as the whole beets are ground into a mash and then cooked. The cooking serves to reduce and clarify the beet mash, releasing huge columns of stinky (but harmless) beet steam into the air. Sometimes, if the air is cold enough, the steam will fall to the ground around the factory as snow!
As we’ve already learned, in the of sugar cane the consecutive rounds of sugar manufacturing produce first molasses and second molasses. With the humble sugar beet, the intermediate syrups get names like high green and low green, it’s only the syrup left after the final stage of sugar extraction that is called molasses. After final processing, the leftover sugar beet mash is dried then combined with the thick black colored molasses to serve as fodder for cattle. Sugar beet molasses is also used to sweeten feed for horses, sheep, chickens, etc.
Sugar beet molasses is only considered useful as an animal feed additive because it has fairly high concentrations of many salts including calcium, potassium, oxalate, and chloride. Despite the fact that it’s not suitable for human consumption and some consider it to be an industrial waste or industrial by-product, molasses produced from sugar beets makes a wonderful plant fertilizer. While humans may reject beet molasses due to the various “extras” the sugar beet brings to the table, to our plant’s it’s a different story. Sugar beet molasses is usually fairly chemical free as well, at least in our experience. Although farmers generally fertilize their fields in the spring using the various arrays of available fertilizers, weed chemicals (herbicides) are not used for this crop due to the beet plant’s relatively delicate nature.
There is at least one other type of “molasses” we are aware of, and that would be sorghum molasses. It’s made from a plant known as sweet sorghum or sorghum cane in treatments somewhat similar to sugar beets and/or sugar cane processing. If our understanding is correct, sorghum molasses is more correctly called a thickened syrup rather than a by-product of sugar production. So in our eyes sorghum molasses is probably more like Maple Syrup than a true molasses.
In the distant past sorghum syrup was a common locally produced sweetener in many areas, but today it is fairly rare speciality product that could get fairly pricey compared to Molasses. Because sorghum molasses is the final product of sweet sorghum processing, and blackstrap and sugar beet molasses are simply waste by-products of sugar manufacturing, it’s pretty easy to understand the difference in expense between the products. The word from the birds is - there isn’t any apparent advantage to justify the extra expense of using sorghum molasses as a substitute for blackstrap or sugar beet molasses in the garden. So if you find sorghum molasses, instead of using it in your garden, you’ll probably want to use it as an alternate sweetener on some biscuits.
That’s a quick bird’s eye look at the differences between the various types and grades of molasses and how they are produced. Now it’s time to get a peek at the why’s and how’s of using molasses in gardening.
Why Molasses?
The reason nutrient manufacturer’s have “discovered” molasses is the simple fact that it’s a great source of carbohydrates to stimulate the growth of beneficial microorganisms. “Carbohydrate” is really just a fancy word for sugar, and molasses is the best sugar for horticultural use. Folks who have read some of our prior essays know that we are big fans of promoting and nourishing soil life, and that we attribute a good portion of our growing success to the attention we pay to building a thriving “micro-herd” to work in concert with plant roots to digest and assimilate nutrients. We really do buy into the old organic gardening adage - “Feed the soil not the plant.”
Molasses is a good, quick source of energy for the various forms of microbes and soil life in a compost pile or good living soil. As we said earlier, molasses is a carbon source that feeds the beneficial microbes that create greater natural soil fertility. But, if giving a sugar boost was the only goal, there would be lot’s of alternatives. We could even go with the old Milly Blunt story of using Coke on plants as a child, after all Coke would be a great source of sugar to feed microbes and it also contains phosphoric acid to provide phosphorus for strengthening roots and encouraging blooming. In our eyes though, the primary thing that makes molasses the best sugar for agricultural use is it’s trace minerals.
In addition to sugars, molasses contains significant amounts of potash, sulfur, and a variety of micronutrients. Because molasses is derived from plants, and because the manufacturing processes that create it remove mostly sugars, the majority of the mineral nutrients that were contained in the original sugar cane or sugar beet are still present in molasses. This is a critical factor because a balanced supply of mineral nutrients is essential for those “beneficial beasties” to survive and thrive. That’s one of the secrets we’ve discovered to really successful organic gardening, the micronutrients found in organic amendments like molasses, kelp, and alfalfa were all derived from other plant sources and are quickly and easily available to our soil and plants. This is especially important for the soil “micro-herd” of critters who depend on tiny amounts of those trace minerals as catalysts to make the enzymes that create biochemical transformations. That last sentence was our fancy way of saying - it’s actually the critters in “live soil” that break down organic fertilizers and “feed” it to our plants.
One final benefit molasses can provide to your garden is it’s ability to work as a chelating agent. That’s a scientific way of saying that molasses is one of those “magical” substances that can convert some chemical nutrients into a form that’s easily available for critters and plants. Chelated minerals can be absorbed directly and remain available and stable in the soil. Rather than spend a lot of time and effort explaining the relationships between chelates and micronutrients, we are going to quote one of our favorite sources for explaining soil for scientific laymen.
“Micronutrients occur, in cells as well as in soil, as part of large, complex organic molecules in chelated form. The word chelate (pronounced “KEE-late”
comes from the Greek word for “claw,” which indicates how a single nutrient ion is held in the center of the larger molecule. The finely balanced interactions between micronutrients are complex and not fully understood. We do know that balance is crucial; any micronutrient, when present in excessive amounts, will become a poison, and certain poisonous elements, such as chlorine are also essential micronutrients.For this reason natural, organic sources of micronutrients are the best means of supplying them to the soil; they are present in balanced quantities and not liable to be over applied through error or ignorance. When used in naturally chelated form, excess micronutrients will be locked up and prevented from disrupting soil balance.”
Excerpted from “The Soul of Soil”
by Grace Gershuny and Joe Smillie
That’s not advertising hype either, no product being sold there. That’s just the words of a pair of authors who have spent their lives studying, building, and nurturing soils.
Molasses’ ability to act as a chelate explains it’s presence in organic stimulant products like Earth Juice Catalyst. Chelates are known for their ability to unlock the potential of fertilizers, and some smart biological farmers we know are using chelating agents (like Humic Acid) to allow them to make dramatic cuts in normal levels of fertilizer application.
One way to observe this reaction at work would be to mix up a solution of one part molasses to nine parts water and then soak an object which is coated with iron rust (like a simple nail for instance) in that solution for two weeks. The chelating action of the molasses will remove the mineral elements of the rust and hold them in that “claw shaped” molecule that Grace and Joe just described.
As we’ve commented on elsewhere, it’s not always possible to find good information about the fertilizer benefits of some products that aren’t necessarily produced as plant food. But we’ve also found that by taking a careful look at nutritional information provided for products like molasses that can be consumed by humans, we can get a pretty decent look at the nutrition we can expect a plant to get as well.
There are many brand’s of molasses available, so please do not look at our use of a particular brand as an endorsement, our choice of Brer Rabbit molasses as an example is simply due to our familiarity with the product, one of our Grandmother’s preferred this brand.

Everytime I have used blackstrap the buds get bigger and denser....they seem to swell alot more.
That was an excellent piece on the Molasses info, I work at a Beet Sugar factory and i liked the proper references being used, but would like to mention that beet sugar diluted at about a half amount of the molasses would do the same thing without bringing several or the chemical impurities into your "soil" that mollasses would

Anyone done a test with and without the blackstrap molasses?

I like to dip biscuits in molasses.
I've used black strap on half of my soil grows (same genetics) and never noticed any difference in taste, aroma, weight, etc. Of course, if you are providing what your plant needs nutritionally, extra additives add little or nothing to the finished product. I'm now exclusively hydro, so molasses is very taboo.
Having said all that, I never had a negative experience using molasses. Your milage may vary. Personally, I never saw a real benefit.

I am using sweet grape for my first ebb n flow grow. It was a bit more expensive but I with it because it was a nice pure liquid so I wouldn't have to worry about any mess or pump getting getting jammed. After reading about the sweet grape it seems like it has same benefits as molasses plus more.
I will let you know how the SWEET GRAPE does for my grow.
