Feed the soil, not the plant.

BioBizz — certified organic, soil first
BioBizz is built around soil growing and certified-organic inputs, which puts it in a different lane from most of the mineral feeds on this site. Bio-Grow and Bio-Bloom are the two-part base — made from plant extracts rather than mineral salts — and Fish Mix adds an organic nitrogen boost early in veg that soil growers rate for leaf development.
Top-Max is the flowering booster, working alongside Bio-Bloom rather than replacing it, and Root Juice covers propagation and transplant stress. Alg-A-Mic and Acti-Vera are stress-recovery tonics worth keeping on the shelf for hot weeks or after any repot, and Leaf Coat is a foliar spray that helps with pest resistance and leaf shine rather than feeding. The Starter Pack bundles the core four bottles at a lower combined price for a first soil grow.
Because it's organic, BioBizz feeds sit lower in EC than mineral equivalents at the same dose — don't judge strength by the numbers on a standard EC meter alone, watch the plant instead, since organic matter doesn't register fully on a conductivity reading the way mineral salts do.
