It’s based on Vic highs mix but slightly different if you’ve ever heard of that, and many people seem to prefer Coots mix, and build a soil products but I never would’ve found out about mixing living soils without Subcool and his approach and info he put out on YouTube on the Weednerd show.

So as usual your mileage may vary, some genetics seem to not thrive in super soil with it being a bit hot, but if you let it cook long enough I’ve only had great results regardless of the above article, which I never saw until growing with super soil for 12 years.
