For those who love fresh mushrooms, now there’s a great way to grow them at home. The Easy-to-Grow Mushroom Garden kit is made to be placed on a windowsill.

This fun garden produces your first one-pound crop of delectable pearl oyster mushrooms in 10 days and only requires a gentle water misting twice a day. The company guarantees you’ll get at least two crops out of it and possibly up to four. The soil in the kit is 100% recycled coffee grounds.

First introduced by Back to the Roots at the Berkeley (California) Whole Foods as a way to have urban mushroom farms be more local, this garden is a great, easy way to teach kids the connection between food and growing things. These easy to use mushroom kits are available at Whole Foods Markets, nurseries, and science stores. It’s safe, sustainable, fun and yields a nutritious product. What more can you ask for?
