Ok guys sorry its been so long, life has been a bit crazy latly but its been about 2 weeks since i jarred the yellow coco thunderhaze auto and weighed it out, i got 212 grams off of her! that is actually more than i have gotten off of my last 2 harvest so i would have to say that you can grow in reused coco with great results and i can say that the coco has already won this coparison. Now i dont want to say this is some scientific or even a great soil vs coco grow but its hard to argue with such drastic differences. i do think i could get my soil skills WAY better as i seem to have some kind of problem in flower every soil grow i have with the exception of this one so i decided to pick up True Living Organics from Skunk Magazine. Now i have heard alot of mixed info on the rev and his TLO style of growing but i know very little about full organic growing and he has alot of interesting consepts so ill let everyone know what ive learned and what i am going to do with the info soon
