Description
Feed little and often, timed to the second
The G.A.S Minute-Second Timer sets exactly how long a pump runs each time it is switched on, from 5 seconds up to 10 minutes. It plugs into a standard segmental timer: the segmental timer decides how often each feed starts, and the Minute-Second Timer decides how long it lasts. That makes short, frequent irrigation cycles easy – the little-and-often feeding that keeps the root zone evenly moist, improves nutrient uptake and lets plenty of oxygen back in between feeds.
Key Benefits
- 5 s to 10 min run times, switchable between seconds and minutes.
- Works with any segmental timer – one segment on per feed.
- For pumps and devices up to 500 W.
- Cancel a cycle instantly by turning the mode dial to OFF.
- Made in the UK by G.A.S, with a 2-year warranty.
Why short feeds matter
A segmental timer on its own switches a pump in whole segments, usually 15 minutes at a time, which floods drip and coco systems and leaves roots waterlogged and short of air. Cutting each feed to seconds or a few minutes delivers just enough solution to wet the media, so roots stay in the moist, well-aerated zone that drives strong root development.
How to Use
- Set it before plugging in: turn the top dial to SECS or MINS and the bottom dial to the run time you want.
- Plug your pump into the socket on the front.
- Set your segmental timer with one segment on for each feed you want in the day.
- Plug the Minute-Second Timer into the segmental timer, then the segmental timer into the mains.
- To stop, turn the top dial to OFF; turn it back to SECS or MINS to resume at the next cycle.
- Adjust the bottom dial any time; change the top dial between cycles so you don't cancel one by accident.

Frequently Asked Questions
Do I need another timer?
Yes. The Minute-Second Timer only sets the length of each run; a segmental timer upstream sets how often runs start, with one segment switched on per feed.
How is it different from the G.A.S Minute Timer?
The Minute Timer runs from 1 to 10 minutes. The Minute-Second Timer adds a seconds range, so feeds can be as short as 5 seconds – useful for drippers and small pots.
What size pump can I run?
Any device or combination of devices up to 500 W in total.
