Control Your Light Cycle. Protect Your Grow.
A missed light cycle can set your plants back days. A power outage at the wrong time can flip your photoperiod and trigger early flowering. The right timer — and the right protection — keeps your grow room running exactly as programmed, every single day.
At Growers Depot, we stock grow room timers and controllers built for Australian conditions: 240V/10A–16A rated, AU standard plugs, and purpose-built for HID, LED and CO2 applications.
What's in This Collection
-
Nakajima Digital Timer (16A) — Heavy-duty 16A digital timer with 48 daily programs, Monday–Sunday day selection, silent operation and a built-in rechargeable battery backup. Handles the biggest grow lights without breaking a sweat.
-
Time-R Digital Timer — Three modes (Timed, Repeat, Combined) with 1-second precision and up to 15 daily programs. Ideal for CO2 controllers, fans and lighting on precise schedules.
-
Timer Box 2, 4 & 8 — Industrial contactor timers for 2, 4 or 8 HID grow lights. 48 programmable segments at 15-minute intervals, resettable fuse, powder-coated steel enclosure and wall-mountable. Built to handle the load that standard timers can't.
-
Heavy Duty 4-Outlet Timer Lead (3000W / 15A) — Plug-and-play 4-outlet timer lead rated to 3000W/15A. Bundled with a Timer Reset Box for complete power outage protection.

Timer Reset Box — Prevents your light timer from auto-restarting after a power outage. Manual reset required before lights come back on — so a blackout never accidentally triggers a dark period or re-vegs a flowering plant.
