I heard about bat guano. Dont know much about it though
Blue Mountain Organics from Ebay
good stuff
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![]()
