24H Mechanical Timer 3680W: rock-solid photoperiod control for indoor growing

In indoor growing, a consistent day/night cycle matters as much as raw light output. This 24-hour mechanical timer switches your LED grow light on and off in 15-minute segments — no electronics, no backup battery, no clock drift. A simple, rugged solution hand-picked by BloomLED to lock in your vegetative and flowering photoperiods.

Why growers choose this timer

🌱 Stable photoperiod, consistent harvests

18/6 in veg, 12/12 in bloom: set the tappets once and the cycle repeats identically every single day. A steady photoperiod reduces light stress and the risk of plants reverting to vegetative growth.

⚡ 3680 W: from one panel to a full room

With 16 A of headroom, this timer drives a single horticultural LED panel just as happily as a power strip feeding several bars, an extraction fan or a nutrient pump. Just keep the combined draw under 3680 W.

🔧 Mechanical means unbreakable

No display, no backup cell, no menu to reprogram after a blackout — the dial simply resumes turning when mains power returns. That is the raw reliability growers want when a tent runs unattended for months.

BloomLED tip: keep the 'always-on' position for low-PPFD cloning stages, then switch back to timer mode as soon as plants enter vegetative growth. A photoperiod drift of more than 30 minutes is enough to unsettle sensitive flowering varieties.

Frequently asked questions

Is this timer suitable for an LED grow light with a driver?

Yes. LED drivers draw a brief inrush current at start-up that the 16 A contacts of this model absorb comfortably. For multi-driver builds exceeding 1500 W combined, BloomLED recommends adding a power contactor and using the timer purely as the pilot signal.

How do I set a 12/12 flowering photoperiod?

Push down the tappets covering your desired lights-on hours — for example 8 pm to 8 am — then rotate the dial until the arrow points at the real current time. Finally slide the side switch to the clock symbol. Each lowered tappet equals 15 minutes of light.
