Just kidding. I bet most people here who use chemical nutes have used GH at some point. I have.
Simple, cheap and effective. A lot of the people running the Lucas Formula use GH Micro and Bloom (google 'Lucas Formula' if you don't know what that is)
Using GH Flora-Micro & Flora-Bloom @ 8ml Micro/16ml Bloom per gallon of water as per Lucas formula,not bad results,a lil tweaking to do but all in all just as good as the FF nutes and additives I used for so many years...and cheaper only needing two bottles instead of all three.
