Ideally you should begin growing your mushroom grow kit as soon as you receive it, but we understand sometimes this isn't possible (eg if you're giving a kit as a gift or going away). 

For pink oyster grow kits: We recommend starting these kits as soon as you have received it as they do not store well.

If you are looking at storing a kit we recommend selecting a white oyster kit as this variety can be stored for a couple of months. Most mushroom kits will store for 2-3 months if necessary. 

To store your kit, keep it at a stable room temperature. Don't keep it somewhere it could exceed 30 degrees Celsius. Somewhere like your pantry or cupboard could be a good spot. 

Never leave your kit in a hot car or in direct sunlight. The mushroom mycelium is heat sensitive and can die from excessively warm temperatures.
