Case of 6 — Sterilized Magic Soil. Save over $79 compared to buying singles. Six 5 lb bags of our premium manure-based substrate blend, each pressure-sterilized and sealed in commercial-grade autoclavable grow bags with 0.5 micron filter patches.
Same substrate as our single bags — composted cow manure, coconut coir, vermiculite, and gypsum — but at bulk pricing for serious growers running multiple tubs.
Growers running multiple monotubs or fruiting chambers simultaneously. Each bag fills one standard 54-66qt monotub at proper substrate depth.
