Small, frequent feeds without the guesswork
The G.A.S Interval Timer automates irrigation for hydroponics, coco and soil, letting growers set both the feeding frequency and how long each cycle lasts. Unlike a basic segment timer, it gives precise control over short, regular feeds, and a built-in light sensor only activates the pump when your grow lights are on - so plants are fed through the day but never watered in the dark.
Key Benefits
- Precise control of irrigation frequency and feed duration
- Built-in light sensor prevents watering during dark periods
- Consistent root-zone moisture for better nutrient uptake
- Supports healthier root development and stronger, faster growth
- Handles pumps up to 500W total load
- Simple to program for any indoor growing setup
Fixing inconsistent watering, root stress and slow feeding
Overwatering suffocates roots and slows development, while underfeeding causes deficiencies and reduced yields. The Interval Timer delivers small, controlled cycles through the day, keeping the root zone evenly moist - especially valuable in coco and hydro, which thrive on frequent feeding. Stable moisture reduces root stress and supports vigorous veg that carries through to denser flowers in bloom.
How to Use
- Plug the G.A.S Interval Timer into your power supply.
- Connect your irrigation pump to the timer (maximum load 500W).
- Position the built-in light sensor so it detects your grow lights.
- Set the feed duration on the frequency dial, from 5 seconds to 10 minutes in 5-second increments.
- Set the interval between feeds, from once every hour up to every 11 hours.
- The timer then activates the pump automatically during light periods for consistent feeding.
