1. If the viability of the strain is weak, the growth of the mycelium may be slow. It is imperative to purchase strains in larger, reputable units. The suitable strain age is 30-40 days, and the hyphae are white, dense and stout, indicating strong vitality.

2. If the bag load is too tight or the water content is too high (above 65%), there is not enough oxygen in the bag to inhibit the growth rate of the mycelium.

3, such as germination temperature is too low, such as less than 20 °C, and poor ventilation or culture material pH is not appropriate (appropriate pH value of 7 or so), can also cause slow development of bacteria.

Cooling Agent

Cooling Agent, is a general term for all the chemicals that can produce cooling effects and are not strong. The most common Cooling Agent is menthol (especially L-menthol), but it should not be used in large quantities due to its strong odor and strong irritation to the skin, mucous tissue, and eyes. Therefore, many scientists have synthesized and extracted a new generation of cooling agent.
