SunBlaster 4" Seedling Dome with Vents - 10″ x 22"

Are unstable grow lights sliding off your propagation trays, or are flimsy covers buckling and destroying your delicate seedlings? Protect your investment and optimize early vegetative development with the SunBlaster 4" Seedling Dome with Vents. Engineered with a patented recessed H-shaped groove, this high-performance dome delivers exceptional structural strength while acting as a secure mounting channel that centers your lighting directly over your plants for perfectly uniform canopy coverage.

By creating a sealed high-humidity microclimate, it prevents rapid medium dry-out and shields fragile cuttings from sudden ambient temperature drops. Designed specifically to pair with high-output lighting, this professional-grade propagation canopy fits securely over Double-Thick, Quad-Thick, and virtually all industry-standard 1020 trays. Take full control over your germination success rates with a dome built to perform season after season.

FAQ

How does the patented H-shaped groove assist with grow lights? +

The recessed H-shaped groove molded into the top of the dome provides a secure resting seat for your grow lights. This specialized track keeps compatible lighting strips perfectly balanced and centered, ensuring your entire tray receives optimal, uniform light distribution.

Will this dome fit standard 1020 propagation trays? +

Yes, it features a highly versatile design footprint. While engineered to perfectly complement the SunBlaster Double-Thick and Quad-Thick trays, it is scaled to standard greenhouse industry metrics and will comfortably fit almost any brand of 1020 tray on the market.

Does this product include the bottom tray or lights? +

No, this item consists of the clear vented NanoDome canopy only. Heavy-duty bottom propagation trays, baseline grow light strips, and seedling media blocks must be purchased separately to complete your customized indoor cultivation setup.

What are the exact dimensions of this seedling dome? +

The dome features an internal growing clearance layout of 10 inches wide by 22 inches long with a 4-inch depth. The exterior unit dimensions measure approximately 21.3 inches long by 11.0 inches wide by 5.1 inches high.

How does this dome help improve seedling success rates? +

The dome locks in essential humidity to protect fragile unrooted cuttings and sprouts. For the best results, we recommend using a SunBlaster Heat Sheet Propagation Heating Mat regulated by a Digital Heat Sheet Controller to maintain ideal root zone temperatures alongside manual airflow control.
