Reishi: what do the growing supplies cost?
Reishi supplies are sold in 6 product categories (grow kits & fruiting blocks, grain spawn, sawdust spawn, plug spawn, liquid culture, agar & lab) across 2 US vendors — 47 listings tracked, 45 in stock, updated July 20, 2026. Prices below are grouped by category because a grow kit, a bag of spawn and a culture syringe are different products; comparing them against each other would be misleading.
