Countertop mushroom grow kits

Every kit includes a fully colonized, ready-to-fruit mushroom block, a reusable growing tray, a humidity dome (your mini greenhouse), a spray bottle, and printed growing instructions. All you add is water.

Both varieties fruit well at normal room temperature (55–75°F). They need indirect ambient light — a kitchen counter near a window or under a cabinet light is perfect. Avoid direct sunlight and heat vents.

Shiitake needs a cold-water shock to trigger fruiting, so you soak the block for 8–12 hours before setting it up. Lion's Mane fruits from a cut in the bag and doesn't need the initial soak. The instruction card in each kit spells out the exact steps for your variety.

Shiitake usually pins within 3–10 days of the cold-water soak. Lion's Mane typically pins in 7–20 days after you cut the bag. From pinning to harvest is another 3–10 days depending on variety and room temperature.

Most kits produce 2–3 flushes over 4–8 weeks. After each harvest, let the block rest for a few days, then soak it in cold water for several hours to rehydrate it and return it to the tray. Each successive flush is usually a little smaller than the last.

Compost it or break it up into your garden beds — spent blocks are excellent soil amendment, and outdoor blocks occasionally throw one more surprise flush.
