Excellent quality standard humidity domes with straight sides allows use of all plant sites in the propagation tray. The taller dome has two clear vents that can be opened or closed to control humidity and a built-in handle for easy removal, while the shorter dome is solid without vents to keep in that more-necessary humidity in early growth stages.
Fits snugly on standard 10 in x 20 in propagation tray. Replacement circle vents are used to replace lost or broken vents on your Super Sprouter dome.
