Product Name: King Oyster Mushroom Fruiting Blocks/Fruiting Bags/Growing Blocks
Substrate Composition: Poplar or eucalyptus sawdust, corn cob, corn flour, wheat bran, and soybean meal
Substrate Characteristics: The growth substrate is fully fermented, sterilized at 121°C under high pressure for 6 hours, inoculated and cultured for 45 days, fully mature, and covered with mycelium, ready for fruiting.
Fruiting Block Description: Our fruiting blocks contain a growth substrate inoculated with mushroom spawn. Once fully mature, they will turn milky white; this white substance is called mycelium. The mushroom fruiting blocks are then ready to be shipped to you. We will teach you how to cultivate mushrooms, which will help you save 50% of your time and effort.

Fruiting Block Weight: 1.75 kg/piece
