Back to the Roots Organic Mushroom Grow Kit 3-Pack

Brand: Back to the Roots

Three boxes in one order: two grey oyster blocks and one pink oyster. The pink strain fruits in warmer rooms and turns a deep coral colour, which makes the set useful when the point is to show a difference between species rather than simply harvest. Each box follows the same ten day cycle of soaking and twice daily misting.

The practical advantage is staggering: starting the blocks a week apart spreads harvests across a month instead of producing everything at once. Downside, three boxes need three humid spots, and pink oysters sulk below roughly 18 degrees Celsius, so a cold flat will slow that one down. Pink oyster also releases plenty of spores, worth keeping away from bedrooms.
