Heavy-Duty Large Humidity Dome Kit with Height Extension, 3 mm Thick Clear Dome, 6x12 Tray

AC Infinity Heavy-Duty Large Humidity Dome Kit creates a stable, high-humidity environment designed to boost germination and cloning success for a wide range of plants. The extra-thick 3 mm clear dome delivers excellent light penetration and long-lasting durability, with adjustable vents that provide precise control over airflow and moisture levels. The included height extension panel increases vertical space for taller seedlings and propagation projects, ensuring flexibility for all stages of early plant development.

A large 6x12 seedling tray supports up to 72 seedlings and is built to drain efficiently, while the heavy-duty drip tray prevents leaks and easily supports the full tray weight. Ideal for indoor growing spaces such as balconies, window sills, and grow tents, this kit provides a clean, portable, and perfectly regulated micro-environment for reliable seed starting and cloning. Pair it with AC Infinity seedling heat mats to further enhance early growth.
