Activate 4 Pro Intelligent Heavy-duty Contactor Timer 4 Way (4 x 1000watt)
Gromatrix 4 Way HID Lighting Event Timer is a quality heavy-duty HID lighting controller capable of switching HID lights on and off effectively and safely and is an integral part of any grow room.
The controller uses an electrical contactor to switch your HID lights and does not suffer the common problems experienced with domestic analogue timers.
The built-in controller has a 24 hour microprocessor controlled real-time clock with 24-48 hour battery backup, 24 programmable timer points a day and much more.
The controller has been designed to be a professional plug and play unit.
The user interface is simple to use and quick to setup in two easy steps:
- Set the current time
- Setup your ON/OFF points
Then the controller is ready for use.
The Lighting Event Timer has all the features of a normal analogue timer plus the following:
The controller's clock can be set to range from a 24 hour day to a 12 hour day, this allows you to have shorter day/night cycles e.g. on 14 hours/off 4 hours which equates to an 18 hour day. During a normal 24 hour day/night cycle plants will usually achieve high growth rates peaking at 100% capacity during the first 50-60% of the day. The growth rates will then decrease rapidly and the last 20-30% of the day achieves minimal growth.
By reducing the length of the day can trigger an increased growth mode where the growth rates are at their peak for the majority of the day. This achieves a very fast growth cycle with full yield potential.
Can be used to simulate the days getting shorter. Once transition has been setup, every time the clock rolls over to a new day the timer point will change by one hour towards its new time. This can help slow down the stretch you can get with some plants from straight switching to 12 hours on/12 hours off.
Resettable Lamps Counters
HPS lamps have a limited lamp life. In addition, their efficiency can tail off quite dramatically near the end of its life. Even though the light might still seem bright to your eyes, your HPS grow lamp will have lost a lot of its lumen output after just a few grows. The lamp hour counters can be used to record lamps on time. When a lamp is nearing its recommended end of life you can replace the lamp and reset the lamp counter.
This feature allows you to override the timer. There are three options lights on, lights off or lights switched on/off with the programmed set points.
View the remaining time to the next on/off set points - a useful feature when running with shorter days.
Why do I need a Gromatrix HID Lighting Event Timer?
When growing with HID lighting you need to switch lights on and off to simulate day/night cycles, this can be done safely with an electrical contactor timer. Normal domestic analogue timers cannot withstand the high current loads required to ignite the HID lighting. Plugging HID lights directly into a domestic timer can cause the unit to prematurely fail and lead to a potential electrical hazard which may result in your lights being fused on or off.
If the timer becomes fused on the HID lights will remain on and your plants will not get a night period. This may go unnoticed as you may not visit your grow room during the dark periods.
If the timer becomes fused off the HID lights will stay off and your plants will not get any light.
