So when I went to buy all my gear for my room I went ahead and got nutrients as well. Now that I'm thourgh my first harvest on these tubs i inherited I re-upped the water and added this stuff to the mix. MINERAL 3 GROW... I also bought two other jugs of the stuff MICRO+ and the BLOOM.. I'm also wondering when and if to add the MICRO+ to the water anyone got an idea on this stuff???? as I have no REAL directions other than mixing charts. thx a bunch

well I mixed it up and nothings dead yet.... hopefully all will go well. and I am runing it a little thinner than the reccomended dossage. I don't got an E.C. meter as of yet, but it's in the wind then I can push the envelope....

K I just got off the phone with my sorta local hydro shop they said this stuff is from "GH" its inorganic, but has been in use since the 70's and these guys seem to swear by it..... so I'll stick with it and maybe consider a switch to bio... or something else later.
