DOWH, Forgot to mention to add back the periods. Link is now working via cheetoes.leads it don't work for me
It is for security reasons. When you link to another site it shows that in the log files. Another reason is to prevent linking images from other domains. Another security risk...All these canna forums seem to do that, I attribute it to paranoia rather than a desire to not share information in the information age. Spurr has gone by a few names, too.
No, it could be anything really, but I'm not all sure how effective it would be if I haven't already heard of it before. There are a few big ones, like kelp and alfalfa.Advanced Nutrients Proprietary Blend of Blooming Co-Factor Plant Extracts
Anyone know what they are referring to.

Hello bestnugzzz, Grow Big soil will not be suitable for hydroponics, due to insufficient nitrate, they have a separate product for hydro if you use their brand.hi can anybody tell me if my(( grow big soil))((foxfarm)) is ok for hydro setup .thanks
Crysmatic..! It's been a while since I've seen you post, brother. :D And you always bring solid info, thanks. You still in touch with spurr, by any chance?
Thanks Seamaiden! I've been lurking for a while. I haven't had anything new or significant to contribute until recently. I've never been in touch with Spurr. I saw his info in this thread, and started looking further into it. Some looks good, other looks iffy.
I've been looking into commercial greenhouses a lot. Fatman's original formula looks a lot like tomato fertilizer...which may not be a bad thing. A greenhouse has to keep its plants healthy for 10 months. We can get away with a shit load in an 8 week cycle.
from Grodan's 6 phase article 5:
N 288 (0.31% NH4+)
P 68
K 274
Ca 309
Mg 53
S 51
Fe 0.95
B 0.90
Mn 0.66
Zn 0.78
Cu 0.10
Si 7
A calyx is a modified leaf. The above 2.88-1.56-3.30-3.1-0.5 is a fruiting formula, so why would we need even more more P than that?
fwiw, Greenhouses run recirculating systems, and amend their reservoir weekly. They use 0.31% NH4+, and they don't use the carbonate/citric acid buffer complex. They don't worry about pH drift. So why does Spurr insist that 33% NH4+ and the buffers is the only way to go?
OK I understand. In this case I think it is fairly difficult to get that low NH4, since you will either have to start using possibly nitric acid, sodium nitrate, copper nitrate things that usually are fairly uncommon. I haven't looked too much into this, normal Hydroponic nutrients are usually around 8-13% if I recall, which is 2-4x the values that Spurr recommends.My bad. I meant 3.1% of total N. ie 279 ppm NO3- and 9 ppm NH4+.
I'm not saying that 33% NH4 doesn't buffer as Spurr claims. I just observed that greenhouse growers don't seem to mind pH drift on a weekly basis. Tomatoes aren't a cash crop - and they've been thoroughly researched. If it increased profits they'd do it.
Not at all. Calcium nitrate has 0% ammonium. Greenhouse grade calnit has ~6.5% (it's a double salt of calnit and ammonium nit). Avoid ammonium phosphates, or ammonium nitrate - not that you necessarily have to. Ammonium nitrate is horribly hygroscopic...so if you don't use it all quickly, it will make a pool of water! (wiki says 59.4% rH is the threshold) Try to measure out anything after that.
2x-4x is 20% - 33% ammonium (80%/20% = 4x). Daniel put an upper limit of 10-15% (nitrate is 6x-9x ammonium). iirc, Daniel's explanation was that nitrate is immediately available to the plant, and more ammonium isn't beneficial in hydro (i.e. buffering).
perhaps greenhouses have such massive reservoirs, that even 200k plants don't swing the pH significantly. I'll look more into that.

im not sure about clearex, but there some peep i saw on ebay who sells humic/root fungus in bulk for pretty cheap if you wanted to add those.
I'm actually working on my own nutrient line, to basically just copy big name formulas and sell them in bulk for a big discount to try to win some customers for anyone who doesn't want to be bothered mixing themselves, but doesn't want to pay out the rearend. Well see how it goes in the next several weeks, I've reverse engineered tons of formulas lately, if anyone wants help on any of the process let me know I'll try to help
