I do know this about it -- it's taken out of bat caves and its removal fucks up their ecosystem. The beneficial bacteria in it protect bats from white-nose fungus, which is fatal to a whole bunch of bat species, and is wiping them out all over North America. Take it away, you reduce the bacteria levels, and WNF takes hold. Dead -- all of em.I heard about bat guano. Dont know much about it though

Yep, UB is right about the phosphorus. Advanced Nutrients did a study and they showed the same thing. The other companies are pumping in way too much phosphorus into their nutrients.General Hydroponics I am told are the best, hands down. I use them, they are pricey. Buttt if youread uncle Bens thread about tip and tricks he states that non-cannabis specific nutes are the best, due to not taking away so much micro-nutes and not jacking the phosphorus during flower like pot nutes do. It yellows fan leaves during flowering and fan leaf health and all around leaf health has a severe impact on flower production aka YIELD. Just ask Benny
