Product Description

A domed germination kit designed to promote successful plant growth and propagation by producing a high-humidity environment. Included within the kit are the humidity dome, grow light bars, and the seedling mat. 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 rotation. 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.

Grow Light Bars

Includes two LED lighting bars that provide luminosity to help strengthen your seedlings’ stems and ensure their long-term health. The dome is specially shaped to fit these strip lights to provide a platform to eliminate the need to purchase and mount external lighting. Features a timer controller with four dimming levels and timer settings that repeat daily to further maximize seedling growth.

Seedling Heating Mat

It also includes a seedling mat that supports the dome’s humid environment by creating steady heat emission beneath the tray. It is lined with far-infrared film that evenly distributes warmth to heat your seedlings from below and accelerate their germination rate. The heating pad’s adjustable dial offers even greater control without disrupting growth by turning the mat on and off.

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 in any room in your home. Quickly and easily transport the domed seedling tray as needed thanks to its practical size. When not starting seeds, you can use the seedling heat mat for other settings and applications like reptile terrariums and homebrewing beverages. With relocatable light bars that can be intensified and used as supplemental lighting, they can also be set in grow tents to help create a controlled, resource-efficient environment throughout your plant's grow cycle.
