oops I meant to say 30 ppm! but a guy at the hydro store said to use RO cause our waters real soft and some other reaosn I can't remeber lol. I was under the impression that promix is hydro? that's what everyone has been telling me, because it's very inert and doesn't have anything in it besides spagnum peat. I trust you over any other average joe feeding me stories though, so I'll take your advice. So just some SRP, azomite, gypsum, bpn 3 part, sweet, ripening formula, ro water and i'm good to go without pHing?
thank you a lot for the detailed response brother
Guy at Hydro store=dipshit.
30ppm, for all intents and purposes IS RO water!!!! You have no good reason to use RO if your tap water is 30 ppm. Just add 10 mil/gallon of CalMag to the tap water.
Promix isn't hydro....not even close. Promix is alive is mychoryzal critters and a good deal of calcium.
If you're going to try mineralizing your soil, you want to use the 6-5-3 ratio you hear talked about. I'd also include some organic doodads too.....maybe some worm castings.
You're likely to grow some very nice plants under those conditions!
