The Back to the Roots Oyster Mushroom Grow Kit is a countertop indoor mushroom-growing system that fruits gourmet pearl oyster mushrooms in 10 days from opening the box. Slice open the bag, mist with water twice a day, and watch a full cluster of mushrooms grow out of the substrate — yields about 1.5 lbs across two flushes.
This is the kit for indoor gardeners with no outdoor space, families teaching kids about food origins, or home cooks who want fresh oyster mushrooms without paying gourmet-grocery prices. The substrate is recycled coffee grounds; the box itself doubles as a planter when growing finishes.
Back to the Roots is an Oakland, California food and indoor-gardening brand. The mushroom kits are made in the USA and the company has earned mainstream press for closing the loop on coffee grounds and household-scale food growing.
