Grower Tip
- Close the vents initially; open one after germination and two when about half the tray has seedlings.
- Use the height extension for taller cuttings while retaining the transparent cover and adjustable airflow.
- Pair it with the IONBEAM S11 to add full-spectrum lighting over the propagation tray.
Features
The 5x8 grid supports up to 40 seedlings while draining excess water into the base tray.
Two rotating vents manage retained moisture, increasing to four vents when the extension is installed.
Clear panels raise the assembled dome to 27.2cm for taller seedlings and cuttings.
The 3mm polystyrene cover admits light and keeps plants visible without lifting the dome.
The polypropylene base catches drainage and supports repeated seed-starting and cloning cycles.
The PET seedling tray lifts from the base for easier handling and drainage.
-
1
Nest the trays
Place the 40-cell seedling tray securely inside the base tray.
-
2
Build the extension
Join the four extender panels with the vented panels opposite each other, then secure the corners with the supplied hardware.
-
3
Choose the height
Set the dome directly on the base or position the assembled extension between the tray and dome.
-
4
Cover the tray
Place the transparent dome squarely over the tray so the enclosed environment remains stable.
-
5
Manage airflow
Begin with the vents closed, then open one after germination and two when roughly half the tray has seedlings.
How many seedlings does this humidity dome hold?
The included insert has a 5x8 grid for up to 40 seedlings. Its cells organise seeds or cuttings, while drainage openings direct excess water into the reusable base tray. Capacity refers to the supplied 40-cell insert rather than a separate propagation tray.
When should I open the humidity vents?
Start with the vents closed to build humidity around freshly sown seeds. Open one vent after germination begins, then open two when roughly half the tray has seedlings. Continue adjusting airflow to suit the crop and room conditions rather than leaving the dome sealed throughout propagation.
Is the height extension included?
Yes. The kit includes two clear side panels, two vented panels and the corner hardware needed to assemble the extension. Place it between the base and dome when taller seedlings or cuttings need more headroom, or leave it out for a lower setup.
Which grow light pairs with the 5x8 dome?
The AC Infinity IONBEAM S11 is the matched light-bar option for this 5x8 dome. Pairing it with the kit adds dedicated full-spectrum lighting above the tray while the clear dome retains moisture and the adjustable vents manage airflow around seedlings and cuttings.
Does this Australian listing include a heat mat?
No. This AC-HDA5 listing contains the dome, 40-cell seedling tray, base tray, height-extension panels, vents and assembly hardware, with no electrical equipment included. The dome itself has no voltage requirement. For root-zone warmth, pair it with the separately sold Growy heat mat and thermostat.
Description
A domed germination kit designed to promote successful plant growth and propagation by producing a high humidity environment. The transparent dome allows for optimal light saturation while offering easy observation of your plants’ progress.
Adjustable vents on the dome offer complete humidity control through smooth and effortless rotating. Make further adjustments with the optional height extender, which can be applied to elevate the dome for cloning projects.
The drip and seedling trays fit seamlessly to support up to 40 seedlings while catching excess water and preventing leaks in the process.
APPLICATIONS
This humidity dome serves as the ideal well-regulated environment for growing seedlings and cloning a wide variety of plants including spices and aromatics. Its compact and durable design can easily fit on balconies, window ledges, in your grow tent, or any room in your home. Quickly and easily transport the domed seedling tray as needed thanks to its practical size. Pair this with the SUNCORE Series of seedling heat mats to further improve germination success.
