Major Tech MTD7-20 Digital Timer – 20 On/Off Daily Programs

Set It Once, Let Your Grow Room Run Itself

The Major Tech MTD7-20 is a digital daily timer for growers who need lights, fans and pumps running on an exact schedule — without having to think about it. Plug it in, program your cycles, and your room holds its photoperiod whether you're standing in it or not.

Why Growers Reach For It

• Up to 20 on/off cycles per day — more than enough for a straight 12/12 or 18/6 photoperiod, with room left over for pulsed irrigation or staged ventilation.
• Battery backup — your programs survive a power cut. No reprogramming the timer every time load shedding hits.
• Accurate to the minute — consistent dark periods matter most through flower, and this holds them.
• Clear LCD display — straightforward to set up, even if it's your first timer.
• Heavy-duty build — rated for the load of grow lights and larger grow room equipment.

What You Can Run On It

Grow lights (LED and HID), inline and extraction fans, circulation fans, water pumps, air pumps, CO2 equipment, and propagation heat mats.
