What a 7 Inch Humidity Dome Buys You Over a Short One
Height is the reason to pick this one. At 21.2 x 11.1 x 7.4 in it clears cuttings that have already stretched, where a four inch dome starts pressing leaves against the plastic within days. The sides run straight up rather than tapering, so every plant site in the tray underneath stays usable instead of the outer rows losing headroom. Two vents in the top open and close, which is the only humidity control a dome really has. Built-in light tracks take the 18 in Super Sprouter T5 HO fixture and can run lengthwise or across. It fits a standard 10 x 20 tray snugly. Taller domes hold humidity less evenly than short ones, so the vents matter more here, not less.
Running a Vented Propagation Dome Through a Rooting Cycle
A vented propagation dome earns its keep in the first week and becomes a liability in the third. Start with both vents shut so cuttings sit near saturation, then crack them once white root tips show. Have the dome off entirely before the plants go under full light. Leaving it closed past that point is how people get damping off and soft, stretched stems. The ultra clear plastic matters more than it sounds. A hazy dome cuts light at the exact stage when cuttings are least able to spare any. Wipe the inside between runs rather than letting mineral film build up. Sitting a light directly in the tracks puts the fixture close, so watch leaf temperature on the first day.
