I have been using
Promix Organic from the hydro store mixed with MagikMoss from a local garden center. 3/1 ratio. The
Promix is loaded with some nice ingredients and the MagikMoss is a very light mix. The bag is light as a pillow. It has been working great with OC+ as my base nutes.
The current grow is the same soil mix, but with
FoxFarm Tomato and Dr Earth Bud and Bloom, minerals, teas, etc. The plants are as healthy looking as the OC+ ones are. Hoping for a little better taste and smell with the organics.
My next soil try will be Dr Earth Pot of Gold. Loads of good stuff in there. I just found it at a hardware across town. They also make a MJ specific soil called POTting soil. I doubt the hardware will carry that, but it looks about the same ingredients as the Pot of Gold
