Active Aqua Humidome for Flood Tables | 2x2 or 3x3, 3-Way Vented

Active Aqua Humidome for 2x2 and 3x3 Flood Tables

This is a large, tall propagation dome made to sit over an Active Aqua flood table. The 3 x 3 ft size measures 36 x 36 in and stands 8.5 in tall. The 2 x 2 ft size measures 26.5 x 26.5 in and stands 9.25 in tall. Each one fits the matching Active Aqua flood table in its size. Three-way ventilation lets you open the dome in stages to bring humidity and temperature down gradually. The extra headroom gives cuttings and seedlings room to grow before leaves press against the lid. More air volume over the table also means humidity and temperature swing more slowly when the lights come on. A full table of plugs, cubes or small pots fits under one lid, so a whole batch shares one environment. Because the dome covers the table, the flood-and-drain cycle can keep running underneath while plants root. That suits growers who root cuttings straight in stone wool cubes on an ebb-and-flow table. The shell is sturdy enough to lift on and off daily during vent checks. It belongs to the Active Aqua flood table system from Hydrofarm.

Running a Tall Humidity Dome Through Rooting

A tall humidity dome holds the moisture cuttings need while they have no roots to drink with. Keep every vent closed for the first few days and mist lightly if humidity drops. Crack the side vents once callus forms at the stem base, usually within the first week. Open the top as white roots appear so the leaves start pulling water through the stem. Pull the dome off entirely a few days before transplant so plants harden to room air. Wipe condensation from the inside if it starts dripping onto leaves, since standing water invites rot. Keep the dome clear of direct heat from fixtures, which can push the air underneath too warm. Gentle bottom heat under the table helps roots form faster. Clean the dome with a mild sanitizer between batches so pathogens don't carry into the next round. Store it flat or nested so the shell keeps its shape.

Key Features
