My pepzyme clear came contaminated. Had some stringy fungi floating around in it. Funny thing is without opening it the level in the bottle continuously dropped. I lost 1/4 before I ever opened it. I still used the contaminated stuff in the soil. I thought pepzyme was to be used 1:4000 pep to h20. A light ml per gal. I've been using 1ml per gallon... Also for the record I got my pepzyme from nutrient dense supply not AEA. Yea if I knew how to use the Co I would, but I'm a bit Leary to be honest. I can't remember what kempf recommends I'll have to listen to the conference again. It's something ridiculously small I'm pretty sure...
