Great for micro-greens, this lightweight, pH balanced, bio-based textile absorbs and retains water while providing an inert environment for dense healthy root development. BioStrate is compostable; however, it will maintain its structural integrity for the life of your crop and won’t clog filters. Just moisten BioStrate® Felt with mist or a quick dip in a water bath and let excess water drain. Sprinkle seeds to the desired density, then mist. BioStrate performs best when not overwatered. The amount of water will vary depending on the system used. The felt should be kept moist, not saturated. Water level should not be higher than the top of the medium. If water pools on the felt, reduce water flow.
