Cornwall Electronics Reversible Hygrostat Plug 220V: your all-in-one humidity regulator
A successful indoor grow depends on humidity as much as on lighting. The Cornwall Electronics Reversible Hygrostat Plug 220V, curated by BloomLED, sits between your wall socket and your humidity equipment. It turns a humidifier or a dehumidifier on automatically, depending on the threshold you set. One accessory, two modes, and a perfectly stable climate from seedling to harvest.

🌱 Truly reversible mode
A single switch flips the plug from humidifier mode (turns on below the setpoint) to dehumidifier mode (turns on above the setpoint). Adapt instantly to vegetative growth, flowering or cloning without swapping equipment.
📺 Clear LCD with remote probe
The backlit display shows real-time humidity and your target setpoint. The remote probe sits away from the moisture source for a faithful reading of the air inside your grow tent or cultivation room.
⚡ Heavy-duty 220V / 16A
Built to handle the inrush currents of ultrasonic humidifiers and compressor dehumidifiers up to 3,500 W. The internal backup battery preserves your settings if mains power is cut.
🔌 100% plug & play
No wiring, no fuss: plug it into the wall, plug your device into it, dial in the target humidity and you are set. Works in every grow tent and any domestic indoor space.
What humidity setting should I use at each growth stage?
Cloning and germination thrive at 70-80 % RH. Vegetative growth wants 50-65 % RH. Flowering should taper to 40-50 % RH to prevent mould. The reversible Cornwall hygrostat covers the whole spectrum.
Can I plug both a humidifier and a dehumidifier at once?No, the plug controls one device at a time depending on the selected mode. To regulate temperature in parallel, pair it with the Cornwall Reversible Thermostat Plug on a separate outlet.
Does the hygrostat keep its settings after a power cut?Yes. The internal backup battery retains the setpoint and clock, so your cycle resumes automatically the moment power is back — a real bonus for automated grow rooms.
The must-have accessory for serious growers: precision, safety and 2-in-1 flexibility, hand-picked and tested by BloomLED experts.
