Hydrating substrate between flushes is a common practice in mushroom cultivation. This involves fully immersing the colonized substrate in water, typically for a period ranging from several hours to a full day. The duration is dependent on the size and dryness of the substrate block.
The primary benefit of this rehydration process is to replenish the moisture content lost during the previous fruiting cycle. Mushrooms are largely composed of water; therefore, each flush depletes the substrate’s water reserves. Insufficient moisture can lead to smaller subsequent yields or prevent further fruiting altogether. Rehydration ensures the substrate remains adequately hydrated, promoting consistent and abundant mushroom production.
