So your saying its a certain way, while also admitting you dont even know why? Are you saying people shouldnt use augmented co2 in flower? Like its a bad thing to do?

I know this isn't directed towards me, but I was really asking. I always just thought it was for veg... haha. Obviously not. I haven't really done much reading on it.

I'm finding this hard to type:



After a mere 3 weeks of (un-desired) sobriety, it took only two rips on the bongaroo to make this hard to type.
A big thanks goes out to my buddy "J" for coming through in the clutch with zero notice!

*I just noticed that my left shoulder, which has been making me feel like a complete wuss for my lack of ability to take the pain without outward emotion, now moves more freely with much less pain after the bong, too.


If I ever form a band, I'm going to name it: Bong.
Or Vape.
Or Doob.

Hmm... I wonder if the name "Jigfresh" has been taken by a band yet?

Carbon dioxide is used by plants for photosynthesis, which only occurs during daylight periods. At night they respire and give off co2.....from wiki answers..............During the day time, there is light coming from the sun. Plants need light to photosynthesise. At night, there is no light, so they can't photosynthesise. Instead, they respire.......................:peace:cof

Here's the long-winded version of it (but well worth the minute to read it):

*from:

http://scienceline.ucsb.edu/getkey.php?key=730

why do plants need oxygen?
Answer 1:
I'l bet you are wondering that because you already know that plants can make oxygen. You probably already know that in photosynthesis, plants take CO2 from the air, Water (H2O) from their roots, and energy from the sun and make sugar (C6H12O6). What a lot of people don't realize is that when there's little or no light, plants do the same thing we do. The break down the sugar to release CO2, water, and energy. This requires oxygen. The reason is pretty complex, but basically, electrons get passed around, and oxygen has to pick them up at the end of the process.
If you measured the amount of oxygen and CO2 dissolved in a lake, how do you think the daytime levels would compare to the nighttime levels?
Would a plant need oxygen if it were under lights 24 hours a day?

Answer 2:
Plants respire, just like we do. When a plant doesn't have access to light, it burns sugar to make energy, consuming energy. It's just that plants use sugars to build their bodies as well as an energy storage, so over the course of a plant's life, as it grows, it makes more sugar than it burns, and so releases more oxygen than it consumes.

Answer 3:
Plants need oxygen for the same reason you and I do -- without oxygen we can't convert the carbohydrates, fats, and proteins we eat into energy. We call this process respiration, and the formula for this sort of reaction is like this:

sugar + oxygen --> carbon dioxide + water + energy

So we breathe in oxygen and eat food, and we exhale carbon dioxide and excrete water.
This exact same reaction goes on in every living cell, including all plant cells. But of course plants don't have to eat food, because they make their own food using photosynthesis. The formula for photosynthesis is basically this:

carbon dioxide + water + sunlight --> sugar + oxygen

You can see that this is basically the reverse of respiration, but plants convert the energy in sunlight into the chemical bonds of the sugar. When cells respire, they break those bonds and get the energy out of them.Anyway, you can see that photosynthesis produces oxygen as a waste product, so for the most part plants don't have to breathe in extra oxygen -- they can just use the oxygen that they produce during photosynthesis. However, plants only perform photosynthesis in the green parts, like leaves and stems, but all plant cells need oxygen to respire. Cells in the leaves get plenty of oxygen from photosynthesis, but cells in the roots often need to get oxygen from the environment to stay alive. Even though roots are buried, they can absorb oxygen from the small air spaces in soil. This is why it's possible to 'drown' plants by watering them too much.
If the soil is way too wet, the roots are smothered, the roots can't get any oxygen from the air, and the cells in the roots die. Without those root cells, the rest of the plant dies. Some plants have evolved adaptations to deal with extremely wet soil. Mangroves are trees that live in swampy environments along the coast in the tropics. The roots of mangroves are often entirely under saltwater, so they have special structures called pneumatophores (Greek for "air carrier") that act like snorkels, sticking up out of the water to get a oxygen for the roots.

And also, the stomata only open to respire when the ambient temperatures cool to a certain point.
So I would think that unless manipulating the room temperatures to induce the stomata to open, or spritzing with cool water periodically, applying CO2 would during lights-on only help the plant endure higher heat, and possibly refract the light differently than an oxygen rich atmosphere?
At night, it would be a benefit to give it fuel to grow when photosynthesis isn't taking place.

To go way down the rabbit hole:
*cannabis is not the plant being used as an example, but the basic botany is there regarding CO2 effects on plant growth

"Effects of CO2 enrichment on the photosynthetic light response of sun and shade leaves of canopy sweetgum trees (Liquidambar styraciflua) in a forest ecosystem"

Which is why oxygen is so important for the roots, and so is a dark period even during veg imo.

I got my veg on 14/10. I cant remember if its roots, or the upper parts, or both grow most at night,,,, one of these if right though. And it cuts down on both the elec bill and heat. I originally started doing this to get my plants used to the outdoor cycle, but i think I'll keep it this way.

14/10 for every kind? Sativa and Indica?

Here are the google search results (lots of awesome info in these pages: came up with a bunch of science pages regarding co2 and photosynthesis)

"effects of co2 on light" was the search terms

So i guess the question is how long to leave the light on in veg to get the most out of the growth, but short enough to cut out the heat and electic bill? Whodat you say you do your 14/10 and no issues? Have you noticed a slow down of any kind? Might be an interesting experiment ofr some of the champion growers here in the 600.....

If plants were people, then co2 would be oxygen. Regular folks like you and I wouldn't see a benefit to posting on RIU with added oxygen. World Class athletes competing in their sport would see a tremendous increase in performance if they had way more oxygen than the other competitors. So it is with plants... if they are pushing the limits in every other way, added co2 will be a big boost, in veg or flower.... it just gives them more available breath, whatever they are up to. If your plants are just putting along (like mine) more co2 isn't really going to do much.

jig is right it all come down to limiting factors . co2 can be used at higher levels then is currently found in the atmosphere only at the time the other limiting factors have been maxed. you need light, food, and co2 if any of this is lacking growth will be limited. I caught sub say he stops the last two weeks of flower. he said you can taste the excess carbon in the bud. it will be after my next move when im in the house I will be buying before I will set up with co2. I can say I will run it in combination with enzyme teas, and bear bulb lighting in my effort to meet the limiting factors. as far as subs claims maybe some controlled experiments are in order. just my two cent

I just cut mine down to 16/8, and am planning on dropping it to 14 next week when they hit the 600 and 12/12 the next. im am trying to give them a chance to root some before the flip, and besides it should be less stressful god knows they have been stressed plenty.

Ahh Im laughing over here. I cant for the life of me think of the plants but theres one that literally lives off of humidity. They grow so slow you'll doubt they're alive, They dont have a root system really, Ive seen them sold glued to a rock... but anyways, thats what jig is working on crossing with his plants :) Seed to harvest in merely 36 years.

This be the plant I think. It's called an air plant. 1 or 2 x a month you soak in water and put it back in the atrium thing.
