                              Fruit it betterA portable humidity tent holds moisture around your kit so you mist less, and a fine mister keeps the surface damp without soaking it.

                              Common questions

                              How do the grow kits work?

                              Each kit is a fully colonized block. Open or cut the bag as the instructions show, keep the surface humid, and give it fresh air and indirect light to trigger fruiting.

                              Where should I put my kit?

                              Somewhere out of direct sun, away from heaters and vents, at the temperature range on the product page. A humidity tent helps in dry homes.

                              Will I get more than one harvest?

                              Most kits produce more than one flush. Let the block rest and rehydrate between flushes.

                              Is the cordyceps kit different?

                              Yes. Cordyceps militaris ships partially colonized in a 2 quart container, and light is its main fruiting trigger.
