- Heavyweight Tray + Dome Set
- Bar Harbor Blend Included
- Reusable, Rigid Plastic
- 30-Day Guarantee
Seed Starting Tray and Dome Kit with Potting Soil is a simple way to get consistent germination without piecing supplies together. T.O. Plastics’ reusable tray-and-dome setup (a 5-pack) is paired with a full 1 cu ft bag of Coast of Maine Bar Harbor Blend Organic & Natural Potting Soil, so you can fill cells, soil blocks, or small pots right away. The clear 2-inch humidity dome helps hold moisture steady during germination, and the heavyweight thermoformed tray doesn’t flex and buckle when you pick it up one-handed. We recommend this kit for anyone starting a lot of veggies and flowers indoors and looking for a fool-proof setup.
Once seeds sprout, the Bar Harbor Blend gives you a container-friendly base that drains and breathes to maintain healthy roots. The tray design skips center bars and side ribs, which makes it easier to set inserts in and clean up at the end of the run. It’s also a nice setup for bottom watering, because the tray gives you a stable reservoir space without feeling flimsy.

Product Tips
- Pre-moisten the potting soil before filling cells so it packs lightly without turning dense.
- Keep the dome on until most seeds germinate, then vent or remove it to reduce damping-off risk.
- Bottom-water once seedlings are up to encourage deeper roots and drier topsoil.
- Label trays at sowing time; domes make it easy to lose track of varieties fast.
- Wash trays and domes with mild soap between runs and let them dry fully before stacking.
