I also have been interested in trying General Organics line of nutes, anyone have any experiences or recommendations on em? Seem a little cheaper than alot of the other organic stuff out there!
Read on a GH blog that they may produce an overabundance of microbial "foam" at the top of a DWC reservoir if the DWC system produces "big bubbles." Didn't read like it was a show-stopper - and the blog mentioned that adding a drop or two of one of their GO components would help "like adding a few drops of oil to a boiling pot" - but something to be aware of. Probably something that every DWC grower experimenting with any organic (including microbes) line would come across at some point.
Have no personal experience with the GO product line.
