A fully colonized fruiting block of Black King, a robust oyster hybrid with thick stems and dense caps. It is sold as an intermediate kit: the block is ready to fruit, but it rewards close control of humidity, fresh air, light and temperature. The first flush typically runs about 0.5 to 2 pounds, and the block can flush again with good care. Compared with beginner oyster kits, it asks more of the grower but delivers meatier mushrooms that hold up to roasting and grilling.

Rated 4.8 out of 5 across 20 ratings, buyers are largely pleased with the block's performance and the mushrooms it produces. The main caveats concern the attention the intermediate rating implies.
The Organic Black King Mushroom Grow Kit Fruiting Block is a fully colonized substrate block prepared for fruiting. It is used to grow Pleurotus spp. at home, indoors. Black King is a hybrid oyster mushroom strain.
The mushrooms have thick stems, compact caps and a dense, succulent texture. Their savory flavor suits roasting, grilling, sautéing and other high-heat cooking.
Place the block in a clean spot with indirect light. Follow the included care guidance for misting and fruiting conditions. Indoors, temperature, humidity, light and fresh air can be monitored closely. Harvest when the caps are well formed.
