Great for growing micro-greens, this lightweight, pH balanced, bio-based textile absorbs and retains water while providing an inert environment for dense healthy root development . Simply moisten the sheets, let excess water drain and place into tray. Then sprinkle seeds to the desired density onto the mat and 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 10 sheets of 9.5” x 19.5” Biostrate Felt, 2 trays and a dome. For Felt refills, see Biostrate 185 Felt.
