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.
Speeds up seed germination and dramatically boosts cloning success rates for fresh cuttings.
Locks in high even humidity and traps heat supplied to sensitive underlying root zones.
Two top-mounted adjustable ventilation dials allow custom balancing of fresh air intake.
Sized at 11x21 inches to fit seamlessly over a double thick 1020 propagation tray or other standard flats.

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.
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.
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.
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.
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.
