    Chitosan Oligosaccharide dosage?

    Ok, if it works then everything is fine. Do you use it in fertigation or as a foliar? And have you measured EC and/or Ph after addition? Just curious because if the main ingredient is some kind of filler/filling salt it should raise the EC quite a bit and could possibly throw your ratios off or...

    Chitosan Oligosaccharide dosage?

    1,5 % and water soluble? That sounds strange. Is there information about what else is in there? Or is that already a stock solution? Normally it is sold in concentrations of >90 % (5g of it last an eternity) and is per se not water soluble. You have to use polysorbate 20 (also called tween 20, a...

    Chitosan Oligosaccharide dosage?

    Triacontanol is best used as a foliar spray but not in such high concentrations. I never go higher than 1 ppm. Most papers recommend 0,01-0,1 ppm to have the best effect for several species (there's no research for cannabis but some other species) and almost all apply it as a foliar spray...

    Here is a recent paper from the University of North Carolina. It shows that there is no increase in cannabinoid or terpene concentration after increasing phosphorus higher than 11,25-15 ppm...

    You're contributing excellent science and knowledge to the table (y) :)

    Yes, i'm sure you love it, who once tried such well working ratios (while saving a fortune btw :)) won't go back. And i'm glad that more and more people jump on that train, too. Fatman had common sense but he sadly got much hate for that although he was right. Even the AN analysis shows that P...

    In hope to make it a bit more clear what i mean by standard deviation: So for a simplified example you want to weigh out 1 gram of a substance with a scale that has 0,1 g readout. At 0,95 g the scale will show 1 g and at 1,04 g it would also show 1 g. (Besides the fact that it could also show 1...

    No, i don't want to say that. It is the same species. I just wanted to say that you have a bigger deviation at smaller numbers.

    Yeah, sure. If one doesn't know what to say after having everything wrong... Now THAT'S fun!

    You can see the error bars at the end, can't you? Do you know about standard deviation? They are both within these range so you can not say it is a 10 percent increase. Also do you see a 10 percent increase for CBD? It is a high-CBD, low-THC variety so at such small differences of 0,03 % points...

    Take a look at this video from Utah State University. At 10:30 mins they show data that shows NO INCREASE in yield or THC/CBD if using 100 ppm phosphorus over 25 ppm P. So 25-50 ppm is all that one would ever need if at all. There is just no benefit in using more. Consider that some even push P...

    Jacks hydro isn't urea based. I said nitrate is urea? Show me where. It gets even more and more ridiculous. As i said you can not even read correctly. Bla bla bla keep on kidding.

    Oh and just for your interest some of those you recommended: For example Emerald harvest micro: Derived from: calcium nitrate, ammonium nitrate, potassium nitrate, urea, cobalt nitrate, iron EDTA, sodium borate, sodium molybdate, copper EDTA, manganese EDTA, and zinc EDTA. Or Cali Pro Bloom...

    Sorry but that is just dumb. Nitrate N isn't the same as urea. YOU should better look that one up. And nitrate isn't chelated with EDTA. Only metals can be chelated with EDTA. You've got that more than wrong. What are you trying to tell me? I've got a Masters degree in chemistry and FOR SURE...

    Urea? I mix my own from Individual salts and don't use any and there is no urea in peters hydro or the others' too. I don't know what you use but all the ones you listed are mineral/synthetic based and not "naturally derived" or "organic". What do you use? For the research here are some vids...

    I prefer 2-1-2 or 2-1-3 (N-P2O5-K2O) all the way through at an EC of 1,2-1,3 (daily fertigation in a peat/perlite/vermiculite based soilless substrate). Nowadays i lean more toward 2-1-2 (after years of 2-1-3) as it was recommended by Dr. Bruce Bugbee from Utah State University for cannabis and...

    Ok that looks good. All values seem reasonable fine so your plants should soon take off.

    Sure everyone can use and pay what he wants. But junk? What do you think all the liquid fertilizers are made of? "Cannabis specific" is just ridiculous marketing bollocks. And so are high phosphorus low nitrogen bloom nutrients as current scientific university research shows.

    Way better fertilizers out there than ALL "cannabis specific" liquid ripoff "lines". Individual salts (or jacks, peters, haifa etc). Better yield, better quality, one percent of the price, no hydro store running. No broscience, no hassle, no dozens of bottles.
