A countertop kit for growing blue oyster mushrooms indoors from an already-colonized organic block. It is pitched at beginners: the block fruits under normal home conditions and the mushrooms roughly double in size every day once they pin. After the indoor harvest you can move the spent block to a garden bed to try for more. Compared with kits that ship dry spawn you have to hydrate and colonize yourself, this one skips the slow start, but it is a single-crop kit rather than a reusable setup.

Buyers rate it highly, with most praising how easy it is to start and how quickly mushrooms appear. Complaints center on uneven fruiting and the mess of oyster spores in the home.
This kit grows Blue Oyster mushrooms (Pleurotus ostreatus) indoors. It contains a colony of living mushroom mycelium growing on a block of enriched hardwood sawdust. The sawdust substrate mimics a fallen log and supplies the food the mycelium needs to produce clusters of mushrooms.
The block arrives in a black cultivation bag. To grow it, set it in a suitable indoor spot and mist it lightly with water every day. The first flush appears within two weeks of activation, and the kit can be harvested for up to a month. The fruiting mushrooms double in size every 24 hours.
After the indoor harvest, the block can be buried in garden soil for possible additional outdoor harvests. Blue Oyster mycelium can also be grown outdoors on organic materials such as spent coffee grounds, hardwood logs, paper waste and straw. Easy-to-follow instructions and recipes for preparing the harvest are included.
