Plants, light, and glass: a simple formula. The Growhouse, however, puts them together in a new way. Inside this compact, glass and brass enclosure is an array of custom, full-spectrum LEDs. You can use the built-in timer to plan out low- and full-light cycles, and the hinged door will keep moisture in between waterings. Whether you place this on a counter, shelf, or mount it on a wall, this is the perfect way to have access to fresh herbs — or house a favorite houseplant — year-round.
