Grow your own micro-greens for super fresh salads and garnishes. This OMRI Listed 100% hemp product is made from fibers grown without the use of pesticides, herbicides or synthetic fertilizers. Simply moisten the sheets, let excess water drain and place into tray. Sprinkle seeds to the desired density onto the mat and then mist. Place dome over the tray and mist each day until greens reach desired stage. Do not let mat dry out (may require additional watering now and then to keep moist). Each kit comes with 6 sheets of 9.5” x 19.5” Puregrown Hemp, 2 trays and a dome. They are single-use and biodegradable so you may compost them. Even in a lightly seeded mat, you run the risk of contamination if you reuse the sheets. For mat refills, see Puregrown 750 Hemp Mats.
