Heavy-Duty Humidity Dome Kit with Height Extension, 3 mm Thick Clear Dome, 5x8 Tray

AC Infinity Heavy-Duty Humidity Dome Kit creates a stable, high-humidity environment to boost germination and cloning success. Its clear 3 mm thick dome offers excellent light penetration while giving you full visibility of seedling progress, and the adjustable vents allow precise humidity control tailored to each stage of growth. The included height extension raises the dome for larger cuttings and advanced propagation projects, adding two extra vents for improved airflow management.

A lightweight 5x8 seedling tray supports up to 40 seedlings, draining excess water efficiently while maintaining structure. The durable drip tray prevents leaks and supports heavier loads for long-term reuse. Designed for grow tents, balconies, shelves, and indoor growing areas, this dome system provides a compact, controlled environment for reliable sprouting and cloning. Pair with AC Infinity heat mats for maximum germination rates.
