G.A.S Day & Night Humidity Controller

Precision Climate Control for Healthier Plants — 24/7


Take full control of your grow room environment with the G.A.S Day & Night Humidity Controller — a smart, reliable solution designed to keep your plants thriving in perfectly balanced humidity, day and night.


Whether you're nurturing delicate seedlings or pushing flowering plants to their peak, maintaining the right humidity isn’t just helpful — it’s essential. Think of this controller as your plants’ personal climate assistant.


Why Humidity Control Matters More Than You Think

Humidity isn’t just “air moisture” — it directly impacts plant transpiration, nutrient uptake, and disease prevention.


With this controller, you’re not just adjusting dials — you’re:

  • Encouraging stronger, healthier growth
  • Reducing the risk of mould and mildew
  • Creating a stable, stress-free environment for your plants

Tailored Day & Night Growing Conditions

Dual Dial Simplicity for Maximum Control

Plants behave differently after lights out — and your humidity should too.


With two dedicated dials, you can:

  • Fine-tune daytime humidity for active growth
  • Adjust night-time levels to prevent excess moisture build-up

No complicated programming. Just simple, intuitive control that works.


Key Features at a Glance

  • Dual humidity settings — separate day & night control
  • Automatic humidifier activation — maintains consistent moisture levels
  • Plug-and-play design — works with your existing humidifier
  • LED status indicator — instant visual feedback
  • Replaceable sensor — long-term reliability

Built for Growers Who Care About Results

Consistency = Better Yields

Fluctuating humidity can stress plants, slow growth, and invite problems you don’t want. This controller removes the guesswork, delivering stable, repeatable conditions your plants can depend on.


Your future harvest will reflect the difference.


Simple Setup, Powerful Results

Getting started is refreshingly easy:

  1. Set your daytime humidity using the left dial
  2. Set your night-time humidity using the right dial
  3. Let the controller automatically switch your humidifier on and off

Green light on? Your humidifier is active.
Flashing? Check or replace the sensor.


Important to Know

This controller is designed to increase humidity only.

If you need to reduce moisture levels, a dehumidifier controller is required.


Ready to Grow Smarter?

Take control of your environment and give your plants the consistency they need.


Add the G.A.S Day & Night Humidity Controller to your setup today and grow with confidence — day and night.
