The Reishi kit produces a beautiful deep red and yellow version of this renowned mushroom used in Chinese medicine. It can be sliced into pieces to make tea, dried and powderized to consume as a food supplement, or grown just for display. They have a fibrous cork-like texture however and so are not for culinary use. 
 
Grow Your Own kits will store refrigerated & unopened (or in a cold, dark place) for up to 3 months.
