Grow1 Premium Propagation Dome with Vents - 10 x 20 x 12-in - Clear Plastic

Steady Humidity for Seeds and Cuttings - 12-in Tall Vented Dome

Seeds and cuttings dry out quickly when the air around them is not humid. This clear dome sits over your tray, lets light in and holds moisture in, so the environment stays more consistent. Sealable vents let you adjust airflow as young plants develop.

At 10 x 20 inches with room for upright growth, this single dome suits hobbyists starting a first tray and regular indoor growers who propagate in standard trays. Growers running larger propagation areas can add one dome per tray.

Key Features & Benefits

• Clear plastic — light reaches the plants while humidity stays in.

Frequently Asked Questions

Q: Will it fit my tray?
A: It fits most 10 x 20-in propagation trays. Check your tray dimensions against the dome before ordering.

Q: What do the vents do?
A: The sealable vents let you open them to release excess humidity and warmth, or close them to hold moisture in.

Q: What is a propagation dome?
A: It is a clear cover placed over a tray of seeds or cuttings. It keeps humidity high and constant while light passes through.

Q: Does it help with warmth?
A: Yes. The dome retains heat supplied to the root zone, which supports seed starting and root cuttings.

Q: How does a dome differ from an open tray?
A: An open tray loses moisture quickly to the surrounding air. A dome slows that loss, so humidity stays steadier.
