Who This Is For

  • You are using a propagation tray because your current environment is too dry for cuttings to establish a root system
  • You are managing a nursery space because you need to stabilize the humidity levels around your plant material

What We Found

  • The two vents on top are simple, but they make a massive difference when you need to gradually harden off new starts
  • The 2.5 inch height is perfect for standard propagation because it keeps the dome from crushing taller cuttings

What Users Say

  • Growers who switched to these domes report that they stopped dealing with wilted cuttings halfway through the cycle
  • Users who added these to their seedling flats say they saved hours of time by no longer misting plants by hand

SunBlaster 2" Seedling Dome with Vents, 11″ x 21″ x 2-1/2″ deep

Are dry indoor environments stalling your seed germination cycles or causing unrooted cuttings to wilt before establishing? Eliminate environmental instability and maintain a highly controlled microclimate with the SunBlaster 2" Seedling Dome with Vents. Specially engineered to seal in life-sustaining humidity, this low-profile cover creates a protective barrier that prevents moisture from escaping, helping young plants build a vibrant root architecture faster.

The SunBlaster 2" Seedling Dome with Vents is manufactured from commercial-grade clear plastic, allowing crucial light to penetrate fully while preventing heat dissipation from propagation mats. At 2.5 inches deep, it offers an efficient low-profile space that focuses heat and moisture directly around emerging sprouts. Outfitted with two manually adjustable top vents, this durable dome gives growers complete control over fresh air circulation, making it an indispensable baseline tool for high-success cloning and nursery propagation.

FAQ

How do the adjustable vents help regulate humidity?+

The two top-mounted adjustable vents allow you to control air circulation manually. Keeping the vents completely closed traps moisture for high humidity, while opening them increases fresh airflow and lowers internal dampness as seedlings mature.

Will this seedling dome fit other brands of standard 1020 trays?+

Yes, it utilizes a highly standard design layout. Measuring 11 by 21 inches, this humidity dome is fully compatible with almost all flats, including the SunBlaster 1020 quad thick tray.

Does the low-profile 2.5-inch depth affect plant growth?+

The 2.5-inch depth is optimal for early seed germination and unrooted cuttings. It concentrates heat and humidity right at the root zone, though taller plants or extended vegetative development may require a 7 inch humidity dome later on.

Can this humidity dome retain root-zone heat from heat mats?+

Absolutely. The heavy-duty plastic structure acts as an insulating blanket over your tray, trapping the upward warmth generated by underlying seedling heat sheets, which can be managed precisely with a digital thermostat controller.

Is this clear propagation cover reusable across multiple seasons?+

Yes, the dome is crafted from a sturdy plastic material intended for multi-cycle use. Simply rinse and sanitize the clear plastic cover between uses to keep it pristine and functional for several growing seasons.
