Trays, Domes & Flats
Johnny's offers a selection of seed starting trays, flats, and humidity domes to accommodate whatever it is you decide to grow. All of our seedling products follow industry 1020 tray standard size (actual footprint: 11" x 21"). We offer supplies that are economical enough to be disposable, but are heavy-duty enough to be reusable over multiple seasons, including: germination trays with and without drainage holes; mesh trays; cell flats; and clear plastic domes. Available in small and case quantities. To compare products, including compatibility across products, see our Trays, Domes & Flats Comparison Chart (at right).
