Substrate & Grain Spawn

50 listings from 6 vendors

Sterilised grain, ready-mixed bulk substrate and the raw ingredients to make your own, from suppliers who pressure-sterilise and pack every bag themselves. Rye, oats, millet and wild bird seed spawn bags sit alongside coco coir, vermiculite and manure-based mixes.

Each listing shows the bag size, whether it ships with an injection port or filter patch, and the supplier's shipping regions. Buy direct from the supplier and every sale settles with them.
