G.A.S Day & Night Humidifier Controller

G.A.S Day & Night Humidifier Controller

The mirror-image of the dehumidifier controller — this one's for dry grow rooms where you need to add moisture during the day cycle. Particularly useful in summer when aggressive extraction pulls humidity out of the tent, or in propagation where cuttings need 70-80% RH to root. Plug your humidifier in, set the dials, walk away.

Why growers choose the Day & Night Humidifier Controller:

• Separate day/night humidity setpoints — propagation wants high-humidity days; late flower wants dry nights
• Works with your existing humidifier — ultrasonic, evaporative, anything plug-in
• Essential for cloning and propagation — cuttings need high RH to root before developing their own moisture retention
• Fixes summer extraction dryness — heavy extraction in hot weather strips humidity; this adds it back
• Simple dial interface — no learning curve, works immediately out of the box

Who it's not for:

If you need both humidifier and dehumidifier control in one unit, step up to the G.A.S Enviro Controller V2. For absolute humidity precision, a digital hygrostat will hold tighter tolerances than a dial-based controller. You'll need to provide your own humidifier.
