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

Adjustable-Vent Humidity Dome for Tall Cuttings & Starts, 7in Clear

Seeds and cuttings need a stable, humid microclimate to germinate and root, but too little ventilation invites damping-off and fungal disease while too much dries out the propagation environment. The SUNPACK SUNDOME line addresses that balance with adjustable vents for humidity and airflow control, in a range of heights, materials, and configurations built around the same standard 1020 (10in x 20in) tray footprint used across commercial and home propagation setups.

This 7in clear dome gives tall cuttings and established starts room to grow, with adjustable vents and clear BPA-free food-grade plastic for full visibility through rooting and hardening-off.

Key Features & Benefits

• Adjustable Vents — dial in humidity and airflow for each propagation stage, then open vents gradually to harden off plants before transplant.
• Standard 1020 Compatibility — fits standard 10in x 20in trays and heat mats used across commercial and home propagation setups without adapters.
• Durable, Reusable Construction — heavy-duty plastic withstands repeated use and cleaning between propagation cycles.
• Height, Color & Light-Track Options — available in a low-profile 2in height or a taller 7in height, in clear or blackout material, with select 7in models adding an integrated Light Track channel for mounting a strip grow light directly on the dome.

Who Should Use This

Commercial propagators, greenhouse growers, nursery operations, and home gardeners who need humidity and airflow control for seed germination, cutting propagation, or growing rooted starts to transplant size.

About Sunpack

Sunpack markets grow light stands, strip lighting, and propagation hardware such as humidity domes through greenhouse and garden supply retailers, for growers who start seeds and root cuttings indoors.

Frequently Asked Questions

What size tray does the SUNDOME fit?

Every SUNDOME model fits standard 1020 (10in x 20in) trays. It's also compatible with standard heat mats of the same size.

How do I use the vents to manage humidity?

Keep vents mostly closed during initial germination or rooting to hold humidity high. Then open them progressively as plants develop, to harden them off before they leave the propagation environment.

When should I choose a blackout dome instead of a clear one?

Choose a blackout dome for light-inhibited seeds that germinate best in darkness, or for cutting protocols that call for excluding light from the root zone during initiation. Choose clear when you want to monitor germination and root development without lifting the dome.

What does the Light Track channel do?

On models that include it, the Light Track is a channel along the top of the dome for mounting a strip grow light directly above the canopy. It removes the need for a separate fixture arm or rigging.

Can the SUNDOME be reused across multiple propagation cycles?

Yes. Clean domes between cycles using a diluted sanitizing solution, rinse thoroughly, and let them air-dry before reuse to avoid carrying over fungal spores from a previous batch.
