Mondi Mini Greenhouse 7 in Propagation Dome | Vented, Fits 10 x 20 Trays

What the Mondi Mini Greenhouse 7 in Dome Does

This clear propagation dome is made by Mondi, the company behind the original patented Mini Greenhouse. It stands about 7 in tall, with a footprint of roughly 21.5 x 11 in to match a standard 10 x 20 tray. The fit is snug, so the dome seals well and holds moisture in around young plants. Two adjustable vents in the top let the grower control temperature and humidity as cuttings root. The extra height gives seedlings and clones more air volume before they touch the roof. Heavy-duty, high-grade plastic lets light through while standing up to many rounds of use. The material washes clean between batches, which helps keep fungus gnats and damping-off in check. This listing is for the dome only, so a 10 x 20 tray and inserts are added separately. Domes stack neatly when not in use, which saves shelf space between runs. It works on a heat mat, under T5s or LEDs, and on any bench where trays already sit.

Rooting Cuttings Under a Mondi Humidity Dome

A mondi humidity dome earns its keep in the first week after cuttings go into plugs or cubes. Mist the inside of the dome and set it over the tray with both vents closed for the first two to three days. That traps humidity near saturation while the stems have no roots to drink with. Open the vents a little each day once the leaves stand up firm, so the clones start to harden off. For seeds, crack the vents once the first true leaves appear to cut the risk of damping-off. Wipe heavy condensation off the roof if drips keep landing on the same leaves. Keep lights a sensible distance above the dome, because heat builds quickly in a closed space. A small thermometer and hygrometer inside the tray takes the guesswork out of vent settings. Once roots show at the bottom of the plugs, lift the dome for longer stretches each day. Wash it with a mild sanitiser between batches so nothing carries over to the next round. Looked after like this, one dome serves many propagation cycles.
