Elm Oyster: what do the growing supplies cost?

Elm Oyster supplies are sold in 3 product categories (grain spawn, liquid culture, agar & lab) across 2 US vendors — 5 listings tracked, 5 in stock, updated November 15, 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.
