Anybody have experience using GH Dry Kool Bloom vs GH Ripen?

Never used any of the GH range don't they contain PGRs ? chemicals like paclo ? they are finding to be quite harmful these days ? maybe me get confused so many different nutes brands these days lol :) the difference between them two feeds is very minimal though and i cant see weather you would notice the difference of not though im not sure the purpose of chlorine in the plants feed I know its good for the stomatas though then that would mean its best used as a foliar feed. Anyway im sure im just typing things you already know lol 👊
