How It Works

You set two thresholds on the EDGE Humidity Controller - a Start value and a Stop value. When humidity drops to your Start value, the controller powers the humidifier. Once humidity climbs back up to your Stop value, it switches off - automatically, with no manual watching or adjusting.

Setting What It Does
Start value Humidity level that turns the humidifier ON
Stop value Humidity level that turns the humidifier OFF

This same controller can also operate a dehumidifier (not included) using the same Start/Stop logic in reverse, if your setup ever needs to reduce humidity instead.

Automatic Humidity Regulation

No more manually turning a humidifier on and off. Set your Start and Stop humidity, and the EDGE Humidity Controller does the rest - running the humidifier only when it's actually needed.

Right-Sized for Grow Tents

The 4L tank covers up to 30m² and runs roughly 12–14 hours per fill at max output, so most grow tents get a full day (or more) of coverage between refills.

Mist Where You Need It, Water Where You Don't

The included flexible hose lets you direct mist exactly where your plants need it - and route the hose so the humidifier itself can sit outside your tent if that's more convenient for your setup.

FAQs

Set a Start value (when the humidifier turns on) and a Stop value (when it turns off) on the EDGE Humidity Controller. It handles the rest - no manual adjusting.

The humidifier holds 4L. To refill, lift the tank off the base, unscrew the cap, fill with clean water (distilled or purified recommended), then reattach the cap and place the tank back on the base.

No. This is a dedicated Humidity Controller with its own built-in sensor and Start/Stop settings - separate from the EDGE Controller included in the Ventilation Kit.

The included flexible hose lets you direct mist exactly where it's needed, and can allow the humidifier to sit outside your tent if that suits your space better. Route the hose without dips or low points, since trapped condensation can restrict mist flow.

It depends on your crop and growth stage - young seedlings and cuttings generally want higher humidity (roughly 65–75% RH), while flowering and fruiting stages typically want it lower (roughly 40–55% RH). Check your specific crop's guidelines for best results.

Yes - EDGE is designed to integrate well with Walden White tents, and is also compatible with most similarly sized grow tents.
