FAQ: How long can I store my ‘rookie roomer kit before use?

The kit contains spawn (mushroom seed).  This spawn is temperature sensitive. It is best to store the spawn in the fridge. This will slow the mycelium growth and helps to keep the mycelium from clumping and getting hard.  Spawn stored in the fridge should last 4 weeks some types of mushrooms can last up to six months in the fridge.
