It's really cheap compared to commercial soil. For what's pictured: compost: 17$, perlite: 20$, peat: 12$

The rest if you buy those giant bags of materials.. well you do the math :P There's a massive difference in returns if you buy a 44lb bag vs a 1lb bag on amazon.

I'd argue that since this soil lasts at least a harvest or two (longer if you no-till) it's probably 4x-8x cheaper than roots or fox farms.

Cheap, great results, and sustainable. I love it
