AC Infinity Large Humidity Dome Propagation Kit - 72-Cell Seed Starting and Cloning System

Create a stable, high-humidity environment for successful seed germination, cuttings and plant propagation.

The AC Infinity Large Humidity Dome, Model AC-HDA7, is a reusable propagation kit designed for starting seeds, rooting cuttings and raising healthy seedlings. Its tall transparent dome helps retain moisture and warmth, while four adjustable vents provide precise control over humidity and airflow.

The system includes a 72-cell seedling tray, a heavy-duty drip tray and a height extension piece for taller seedlings or clones. Its clear PET construction allows excellent light penetration and makes it easy to monitor plant development without removing the dome.
