Grow kits & fruiting blocks: prices across US vendors
20 species and 126 current listings at 2 vendors, updated October 20, 2026. Every price on this page is per kit, and all of it is one product category — so these numbers are directly comparable. A kit here is never compared to a product in another category.
All-you-need-to-fruit kits, fruiting blocks and starter blocks. Compare the same species across vendors — a kit is a kit, but a kit is never comparable to a bag of spawn.
