What is the difference between a kit with the spawn included and a kit with a spawn voucher?

Mushroom spawn is a living organism, it requires specific storage conditions and must be used within a certain time frame. If left unused for an extended period or not stored within the recommended temperature range the spawn's quality and productivity will become impaired. 

The voucher system in our gift option/spawn voucher kits eliminates this issue by replacing the living spawn that can be redeemed separately, at no extra cost. This means you can buy a kit in good time, gift it to a lucky friend/family member and there is no pressure for them to use it right away. 

Kits with the spawn included are intended for immediate use.
