Maybe I'm not understanding what your saying, its entirely possible, but other fertilizers aren't as complete as MegaCrop. I've used Cocotek and got good results, but MegaCrop is just as good + silic/kelp/b vitamins etc.. and cheaper.
I want to give it a try. I like saving money if it's the same. I had written a long response. But I'm doing to stop using coco in two grows and graduate to a recirculating DWC setup.
I bought a small boy, but later found out that I have hard water. I want to try an only organic run as well.
I've used alot of products, and I do love the results I get. I got 3.5 lbs of 3 lights once with Pineapple Express. 3.5 real pounds, not counting all the scraggle and other stuff. Trimmed.
I personally love Fox Farm, but am using the GH cocotek atm because I had some left over. I did a 7 gallon coco tomato and pepper garden. It was too hot and this year was BAD for bugs. I truly pity anyone that had a clandestine outdoor patch this year.
I have blizzard bush, cowboy kush, eagle scout and a bunch of others. But I chose the Bodega Bubblegum and I can see from the pictures in this thread that I will not be disappointed. I just want something smooth and relaxing. Sativas are awesome, but sometimes you need a good Indica dom hybrid. Totally going to save the more bubblegum pheno if I have to choose between a few keeper level clones.
