SUNPACK SUNDOME Blackout Vented Humidity Dome - 7in - Fits Standard 1020 Trays

SUNPACK SUNDOME Blackout Vented Dome - 7in Humidity Control for Propagation and Seed Starting

The SUNPACK SUNDOME Blackout Vented Humidity Dome provides reliable humidity and temperature retention for rooting large cuttings, growing cuttings to size after rooting, seed germination, early seedling growth, and propagating smaller cuttings. Heavy-duty blackout plastic with adjustable vents to dial in the exact humidity level that each crop stage requires. The blackout material blocks light entirely, enabling precise photoperiod control and light-off periods for light-sensitive crops. Compatible with standard 1020 (10in x 20in) trays and heat mats, the SUNDOME integrates into any standard bench propagation setup without adapters.

Key Features & Benefits

• 7in Profile: Tall profile provides ample headroom for large cuttings, established rooted starts, and crops that develop significant vertical growth before transplant.
• Adjustable vents: Adjustable vents let you gradually increase airflow as plants mature, reducing humidity incrementally to harden plants off before they leave the propagation environment.
• Blackout Material: Blocks light completely for photoperiod-sensitive crops or when a dark period is required to initiate or manage specific growth responses. Also helps conserve irrigation between watering cycles.
• Standard 1020 Compatibility: Fits all standard 10in x 20in seed flats and heat mats - works with virtually every commercial propagation tray on the market.
• Durable Construction: Heavy-duty plastic withstands repeated use, cleaning, and the humid propagation environment without cracking or warping.

Who Should Use This

Commercial propagators, greenhouse growers, and nursery operations who need reliable humidity control for rooting large cuttings, growing cuttings to size after rooting, seed germination, early seedling growth, and propagating smaller cuttings will find the SUNDOME Blackout Vented a practical, standard-footprint choice. The blackout version is particularly useful for photoperiod management and light-sensitive propagation programs.

Compatibility

The SUNDOME Blackout Vented fits standard 1020 (10in x 20in) trays and heat mats. The 7in profile requires adequate vertical clearance on your bench or rack system. BPA-free food-grade plastic is safe for use with edible crops.

Frequently Asked Questions

What size tray does the SUNDOME fit?

The SUNDOME fits standard 1020 (10in x 20in) trays and is compatible with standard heat mats of the same size.

How do I adjust humidity with this dome?

Open the adjustable vents progressively over time to increase airflow and gradually reduce humidity as plants develop - mimicking the transition from the high-humidity propagation environment to ambient growing conditions.

Is the SUNDOME safe for edible seedlings?

The blackout SUNDOME is made from heavy-duty plastic. For edibles, confirm material safety with Sunpack directly if BPA-free certification is required.

Can I use the SUNDOME with a heat mat?

Yes. The SUNDOME is compatible with standard 1020 heat mats. The dome traps the warmth generated by the mat, improving the temperature consistency of the germination and rooting environment.
