WonderSoil Wafer Refill (10-Pack)

Our specially-formulated Wondersoil™ compressed wafers are the perfect size and composition for your Microgreens Kit. Made of coconut coir and highly compressed into 2-inch wafers, these are a mess-free and totally sterile way to grow microgreens without risk of disease or pests.  Add a cup of water to these wafers and watch them magically and *instantly* expand into an entire tray of fluffy growing medium.
