Oyster mushrooms need a little light to grow. Favor indirect sunlight and avoid anything that could dry out the block: drafts, radiators, direct sun.

Early in their growth, the caps can double in size each day. When growth slows and the caps turn light gray, it's the right time to harvest. Harvesting the mushrooms young gives better storage life and a more tender texture.\u003c\/p\u003e\n\u003cp\u003ePull off the clusters by twisting them. Remove any leftover pieces of stem on the substrate and keep it moist until the next harvest.\u003c\/p\u003e\n\u003cp\u003eWe usually get 3 harvests per block. The first is the most abundant; each following one is roughly half the size of the previous.\u003c\/p\u003e\n\u003cp\u003eOyster mushrooms keep for about 7 to 10 days in a paper bag in the refrigerator.
