When it comes to growing organic, living soil, nothing is better in my opinion. Not the cheapest but if you care about what's in your nutrients (ie. Heavy metals, PGR's etc.), and where your nutrient ingredients are being sourced, then BAS is where it's at.
Growing Organic is also one of the best nutrient companies out there for real organic products and they make the Kashi blend as well as the Insect frass ferment I used throughout this grow. Check them out and use my discount code CollinT if you decide to grab something 😉.
