Hahaha, kinda like a trailer park... good stuff man. I've always thought you seemed like a cali kinda guy, but you can't leave the mitt broham, sorry. Back on topic.looking good matt. I think Cali may be calling her long lost son home if these dipshits that run things in the midwest keep it up. I miss the Sierra Nevadas a lot anyways. It isnt something you get outta your system easily, kinda like a trailer park.
and bluej- I am cutting out vega at around day 7-10. in week 1 they get 25ml vega, then water. in week 2 they get the same, but I think im gonna add 10ml budswell here as a phos boost, the next 4 weeks get 30ml flores at start of week, and on waterings they get 5ml flores bumped up to 20 mls as needed through week 6 and then I taper off to finish. 1 week flush, anymore is kinda a waste of yield.
5ml/ gallon is exactly what I tried on my current run with OGs. Its the first time I've used the Natural BLOOM as part of my KP boost. It seems to have done the job as I see only a few leaves doing the P curl, mostly older lower ones. Biocanna def needs some P help IMO tho. My KP boost is: 1/8tsp Techniflora Seaweed 1-1-16, 5ml Natural BLOOM 0-10-0, and 5-7ml organic Blackstrap Molasses ~0-0-4 per Gallon. Totaling to around 1-11-20 (KP boost = twice the K as P) I ran my KP boost starting at week 3 thru week 5. I alternate food and tea and only add KP boost to my nute waterings. The yield seems down compared to my last OG plants but I can't tell what variable its from. (New mix, vegan nutes, different pruning mostly for solventless hash making 8P, got hot quick here this spring so went from 1000 to 600 midway thru) Have some pics just no time to get em off my camera today.NightbirdX
I have heard of people using Humboldt Natural Bloom as a bloom booster. Anyone have any experience with this? I was thinking maybe of adding some of this on the watering day earlier in the bloom phase until I reach full swing with Flores. How is this used? Would 5ml/gal 1x a week and adjust from there, be about right?
Dank Raptor I learned (I think from this thread/ Teaming with Microbes) that high P environments can actually hinder certain forms of fungal development. Other than more time for breakdown, facilitated microbial breakdown, why do you feel that this high P product is GOOD for fungal tea?Dank Raptor
ya I like to brew the Bloom for 24 hours. I have found that the soft rock phosphate is good food for a fungal dominant brew so I have been using it as a food source in fungal tea. I believe this helps break it down for the girls. Keep in mind the stuff is very light and hard to burn your plants with.
I use the Glacial Rock and Baseline Humic in my mix. I do put some Baseline in my teas but stopped using the glacial in them (was doing TBL/gal). I like the glacial rock in my mix tho. Great for micros and some also say that it puts our containered plants back in touch with the earth's magnetic fields and hippy whatnots, which I am also into.trichmastaHow bout this...
http://vitallandscaping.com/index.ph...d=37&Itemid=22
This is the newest addition to my tea's at 2 tbsp/gal
Speaking of hippy dippy and whatnot, do you plant by the lunar cycle Kalyx? I just had a conversation with someone that has me thinking I want to try it lol.I use the Glacial Rock and Baseline Humic in my mix.

In my teas for micros I use kelp (of course), a product called FULVEX by botanicare (omri listed fulvic/micros) which I LOVE (two bottles in one) and have used progress earths TONIC product which is $$$pricey but also contains all the biodynamic preps in addition to two salt sources of natural micros and trace elements.
Love and Light. Hope everyone had a good 420 and didn't do too much impulse buying at all the industry sales pushes! LOL
Matt, if the farm move isn't too much maybe you can shed some light on the P vs. fungal growth thing for us. NICE spread we are all jealous! 'cept the moving part, my back hurts enough just lifting out my 5 gallon bags! It will be worth all the work for high end outdoor tho! cant wait to hear about it on the HUGE VEGANIC PLANTS thread. The SUN for the win!
Ya I like it here, but the people that run it are idiots. But I really at least to take a nice long vacay to cali to recharge my batteries. I need to hit up the mountains, SF area, and so cal. Then I will be good for a bit longer.Hahaha, kinda like a trailer park... good stuff man. I've always thought you seemed like a cali kinda guy, but you can't leave the mitt broham, sorry. Back on topic.
Kalyx, I am more then happy to explain.

No I haven't come that far on the journey yet... But I'd bet anybody a gram of veganic OG wax that moon cycle awareness and the dedication to learn about and time plant cycles with nature's cycles will make our favorite crop DANKER at harvest, everything else done correctly and consciously as well. I am a firm believer that even indoor crops are more in touch with higher cycles than modern humans pay attention to. I've grown Four o'clocks indoors under lights and no matter what the light cycle/time of year they opened their flowers at Four DAILY, awesome.WitchDoctor

Mycorrhiza and soil phosphorus levels

Introduction:
Mycorrhizae are an integral part of most plants in nature (Giazninazzi et al., 1982)
and occur on 83% of dicotyledonous and 79% of monocotyledonous plant
investigated (Wilcox - 1996). All gymnosperms are reported as being mycorrhizal
(Newman & Reddell, 1987). Infection of the root system of the plant by these fungi
creates a symbiotic (beneficial) relationship between the plant and fungus.
Upon root infection and colonization, mycorrhizal fungi develop an external
mycelium which is a bridge connecting the root with the surrounding soil (Toro et al.
1997). One of the most dramatic effects of infection by mycorrhizal fungi on the host
plant is the increase in phosphorus (P) uptake (Koide, 1991) mainly due to the
capacity of the mycorrhizal fungi to absorb phosphate from soil and transfer it to the
host roots (Asimi, et al. 1980). In addition, mycorrhizal infection results in an
increase in the uptake of copper (Lambert, Baker & Cole, 1979; Gildon & Tinker,
1983), zinc (Lambert, Baker & Cole, 1979), nickel (Killham & Firestone, 1983), and
chloride and sulphate (Buwalda, Stribley & Tinker, 1983). Mycorrhizae also are
known to reduce problems with pathogens which attack the roots of plants
(Gianinazzi-Pearson & Gianinazzi, 1983).
Influence of Phosphorus on Mycorrhizae:
The benefits listed above are greatest in P-deficient soils and decrease as soil
phosphate levels increase (Schubert & Hayman, 1986).
Very high and very low phosphorus levels may reduce mycorrhizal
infection/colonization (Koide, 1991). It is well established that:
z infection by mycorrhizal fungi is significantly reduced at high soil phosphorus
levels (Amijee et al., 1989; Koide & Li, 1990)
z the addition of phosphate fertilization results in a delay in infection as well as a
decrease in the percentage of infection of roots by mycorrhizae (deMiranda,
Harris & Wild, 1989; Asimi et al., 1989)
z an increase in the level of soil phosphate results in a reduction in
chlamydospore production by the fungus (Menge, et al. 197. These spores
are involved in root infection and spread of the fungus through the soil profile.
Research by Abbott and Robson (1979) concluded that levels of soil phosphorus
greater than that required for plant growth eliminated the development of the
arbuscles of vesicular-arbuscular (VA) types of mycorrhizae. Arbuscles are
structures produced within the host plant cells by the VA mycorrhizae. These
structures are responsible for the transfer of absorbed nutrients from the fungus to
the plant. The arbuscles resemble miniature shrub-like trees (arbuscular = shrub in
Latin). Mosse (1973) reports adding phosphate results in no arbuscles forming.
What levels of P are critical?
When the soil level of bicarbonate-soluble phosphorus exceeded 140 mg kg -1 (140
parts per million) the rate of infection was found to decrease (Amijee et al. 1989).
Abbott and Robson (1977 & 197 found the mycorrhizae Glomus fasciculatum
ceased to be effective when the soil level of phosphorus reached 133 mg kg -1 [133
parts per million (ppm)]. Schubert and Hayman (1986) found mycorrhizae was no
longer effective when 100 mg or more of P was added per kilogram of soil (100
ppm). Mycorrhizal infection virtually disappeared with the addition of 1.5 grams or
more of mono calcium phosphate per kilogram of soil (Mosse 1973). With small
additions of phosphorus fertilizer, entry points and fungal growth on the root surface
remained normal but arbuscles were small and fewer in number reducing the
effectiveness of the fungus/plant relationship. Other researchers have reported
mycorrhizal infections tend to die out in soils containing or given much phosphorus
(Baylis, 1967; Mosse, 1967). The development of mycorrhizal relationships were
found to be the greatest when soil phosphorus levels were at 50 mg kg -1 (50 ppm)
(Schubert & Hayman, 1986).
Summary and recommendations:
The benefits of mycorrhizae are greatest when soil phosphorus levels are at or
below 50 ppm (50 mg kg -1). Mycorrhizal infection of roots declines above this level
with little if any infection occurring above 100 ppm P even when soil is inoculated
with a mycorrhizae mix.
Prior to inoculating soil with mycorrhizae, a soil test should be conducted. If
phosphorus levels are greater than 50 ppm the addition of mycorrhizae will likely be
ineffective.
The level of phosphorus in the plant also has been shown to influence the
establishment of VA mycorrhizae with high levels inhibiting colonization by
mycorrhizae (Menge, et al. 197. Foliar applications of phosphorus therefore
should be avoided when inoculating soil with mycorrhizae.

So I get it that the rock dust known as 'soft rock phosphate' will present for mineralization P, many micros, usually Ca, and possibly more depending on its source, as well as provide a physical medium for them to occupy. This makes sense to me to boost up a fungal tea. (What we learned from your teaming with crobes quotes, thanks for digging em up)But anyways DR, apart from citations for one another; what improved about your fungal Tea with more rock phosphate in there? Also do you think there is a better form of it (i.e. straight powder vs. chelated with kelp plus calcium from Humboldt nutes) for boosting the fungal Tea? I understand there are MANY more types of fungi involved in our containers than just Mycorrhizae and want to learn to boost ALL of the bennies!
So now I've distilled my questions better. I think I already have your answer but ill ask again.Dank Raptor
This is because the symbiotic relationship the fungus has with the plant and the naturally occuring phosphorus is destroyed. The plant needs less and less mycorrhizae for uptake because the relationship is being interfered with chemicals.
In summary, soft rock phosphate is an organic form of phosphorus that is not instanly available to your plants. It promotes fungal growth because it is necessary for your plants to break it down. On the other hand, phosphorus fertilizer bypasses the relationship required by the fungi in order for your plants to receive it. Therefore mycorrhizae population is decreased with chemical phosphate but increased with soft rock phosphate.
What I wanna know from your real world experience is why Natural BLOOM is good for the fungal tea?
I like it because it is real simple. SRP,Kelp and calcium. My hydro store does not sell any other form of soft rock phosphate thats not in a bottle so I dont have anything else to compare it to.
1. Do you consider the Natural BLOOM a P fertilizer, or a liquid soft rock phosphate?
I consider it an organic source of phosphorus, calcium and kelp.
2. My thoughts are since its chelated it will act more as P fertilizer from the article as far as root availability and then MAY convince the plant to nurture its myco bennies less, or not very well at all if its getting all its P from a chelated liquid source which IS readily available.
Do we care about this issue, or is myco dieoff a sacrifice you are willing to make to present more (overrated) P to the plant?
I would never knowingly feed my plant anything that promoted any type of damage to myco. The kelp may help break down the soft rock phosphate. If I knew of them using any type of chemicals to do the job I would find another source of phosphorus.
I have heard what you say about P leaching from soil when growing outdoors. That goes to say that less should be used indoors than outdoors, but doesnt necessarily mean that P is overrated and less should be used. I am fully aware of how much my plants can take. Indicas love phosphorus, it helps give hard buds.
Are you saying you use a PK booster, or just stating the fact that you feed twice as much potassium as phosphorus when boosting your crop? What do you use for potassium and phosphorus?
I am interested in your thoughts, you obviously have some knowledge and yes quality is essential. Especially the way things are these days.
Soft Rock Phosphate should be available at any nursery etc. Its getting more expensive because all the easy to mine reserves are gone and now the rock is sourced mostly in countries that don't like USA extracting all their wealth. I can't believe your grow shop doesn't carry it with their other granular amendments, their loss if you have to buy at a nursery. Which is what I'd do if you care to do a side by side vs. Natural BLOOM, I think its like $25ish a bag where I've bought in the past. Here is a link with tons of details about peak Phosphorus:Dank Raptor
I like it because it is real simple. SRP,Kelp and calcium. My hydro store does not sell any other form of soft rock phosphate thats not in a bottle so I dont have anything else to compare it to.
What I'm saying is that maybe just P itself (organic or synth based) if over-applied could lessen the plants interest in its myco colony, so I reinnoculate after I'm done lightly stressing them with extra P application in weeks 3-5. Even if there is ZERO synth P applied, IMO just the presence of root absorbable P (I assume this is what the rock phosphate in Natural BLOOM has been processed into) could harm the myco.Do we care about this issue, or is myco dieoff a sacrifice you are willing to make to present more (overrated) P to the plant?
I would never knowingly feed my plant anything that promoted any type of damage to myco. The kelp may help break down the soft rock phosphate. If I knew of them using any type of chemicals to do the job I would find another source of phosphorus.
There is a lot of data on the differences in indoor vs outdoor from a rhizo-perspective. The article says it well. I dunno about the wording 'should', I guess I'm just saying less 'can' be used without losses in yield/quality. And yes I have been testing this theory on my last few grows (see KP boost lower down) Maybe indica is just more stress resistant as these varieties evolved in more of a mountainous desert compared to the paradise the sativas evolved in? So indica kinda likes more stressors to bring about a full genetic response to the environment? DunnoI have heard what you say about P leaching from soil when growing outdoors. That goes to say that less should be used indoors than outdoors, but doesnt necessarily mean that P is overrated and less should be used. I am fully aware of how much my plants can take. Indicas love phosphorus, it helps give hard buds.
PK booster = flashy label, overmarketed, "miracle juice" that usually costs a LOT (especially ANs BS knockoffs of everyone else's good sellers)Are you saying you use a PK booster, or just stating the fact that you feed twice as much potassium as phosphorus when boosting your crop? What do you use for potassium and phosphorus?
DR I found your Fungi Dominant Brew recipe in the AACT thread. I believe where our conversation started was my wondering what you do (other than utilize Natural BLOOM in it) to make general tea into a specifically fungal dominate one. From this post I see you do multiple things. So basically I'm gonna answer my below question for myself (based on this here) cause I don't want to stall out this rad thread. My ?:
Dank Raptor
Just mixed up a Fungal dominant brew.
I use the method of cultivating fungi in a 50/50 mix of soil and compost. Add 2 tblspoons/cup of oat bran. Innoculate the mix with spores and put in 80 degree temp for 3-5 days to grow mycellium. Stuff the fungi compost in some pantyhose and brew for 18-24 hours. Try to avoid longer times because this can make your brew go bacterial. (not necessarily bad)
Fulvic Acid 2 ml/gl
Soft Rock Phosphate
Liquid Kelp 4ml/gl
Molasses .5ml/gl (very little dont want bacteria)
Humic Acid 1 ml/gl
Liquid Fish Hydrolysate 4ml/gl
So now that I found this older post I have the answer to my question. I am answering my own ? more for clarification for others b/c I get that you (DR and most other organic long-timers) understand these points as you do these practices in YOUR fungal dominant tea.Kalyx
what improved about your fungal Tea with more rock phosphate in there? Also do you think there is a better form of it (i.e. straight powder vs. chelated with kelp plus calcium from Humboldt nutes) for boosting the fungal Tea? I understand there are MANY more types of fungi involved in our containers than just Mycorrhizae and want to learn to boost ALL of the bennies!
I think this discussion is pretty important for the (mostly)vegan growing style as it is tough to find vegan P sources that are potent like the animal derived ones. However it seems that K is abundantly available in the plant kingdom (probably because it is actually more utilized in the cellular composition of most plants, also the case in cannabis) So do we need to spend the money on all the P amending? What do you think?Greenchile
Ive grown with Subs supersoil multiple times and have mixed it up in different base soils.
Ive made it with ocean forrest and fertiloam, ocean forrest and roots, ocean forrest and happy frog, and just plain roots. There really isnt that much of a difference to be honest. The PPM usually was around 1200-1800 and every now and then I would experiance a Zinc lockout from too much phosphorus.
I personally found the soil to work better by replacing the High Phosphorus Bat Guano with Kelp Meal since the mix has too much phosphorus and not enough potassium.
You get plenty of phosphorus from the bone meal, in my opinion. Plus if you want, you can always add a little bit of guano a few weeks into flowering via top soil feeding or tea if your plants really needs it.
Also, If your plant has been in the supersoil mix for longer than 3 weeks, you need to add a little epsom salt with your feedings.
Please keep us updated on the BT Plus availability and any formula changes (to vegan?) that you hear about. Danks for the bio-update share!+ WitchDoctor +Bio Rhizotonic is for sale in the US now if anyone doesn't know yet. I just bought some here in Michigan at a local hydro store. Can't wait to try it out! I believe they can get Bio Terra Plus now as well, and I think it's vegan now.
