My next 4 plants will be in Coast of Maine Platinum soil, and the use of tea. Can't wait lots of fun.A couple of thoughts but with the disclaimer that I still haven’t gotten it right. After using fox farms souls for a while, my next purchase will be roots organic. I think FF may have lost its way.
As far as mixing soils, I mix my FF currently with basic promix BX, it doesn’t bring much nutrition to the party but the soil drains/dries better and it’s allowed me to play with the ratios with less variables.
another thing I’m considering is taking a swing at some of the super soil mixes, a bit more of a pain to have to buy “more stuff” but I have been watching a lot of talented organic growers have great results so it has peaked my interest.
