VIVOSUN LCD Digital 7-Day Timer with Dual Outlet — Programmable Grow Room Automation
Best for: Growers who need reliable light and equipment timing without faffing about with manual switches
Our thoughts
This is the timer we recommend most for first-time automation. Twenty on/off programs across seven days, dual outlets running independently, and a large LCD display that actually lets you see what you're doing. Solid piece of kit that takes the guesswork out of consistent growing. Does the job properly without the premium price tag.
The VIVOSUN LCD Digital 7-Day Timer with Dual Outlet is a programmable digital timer built for grow rooms and hydroponics setups where consistency matters. Two independently-controlled outlets let you automate lights, fans, pumps, or humidifiers simultaneously. With up to 20 on/off program groups, a large backlit LCD display, backup battery, and UL safety certification, it removes the human error from environment control and gives you the reliability your plants actually need.
How it compares
This sits at the sweet spot for residential and small commercial growers.
-
Digital vs mechanical: This offers precision programming (down to 1-minute intervals) where mechanical timers lock you into fixed 15-minute increments. More control, less compromise.
-
Dual outlets: Two independent devices running on one socket space. Competitors offer this at similar price, but VIVOSUN's 20 on/off program capacity edges out cheaper models limited to 8.
-
Display and usability: The larger LCD is easier to read and program than cramped digital rivals, especially when you're tired or in low light.
-
Battery backup: Built-in rechargeable battery keeps your programming intact during power cuts — no resetting after a trip.
In plain terms: you get laboratory-grade automation at a price that doesn't sting.
Usage guidance
This timer handles most grow room automation scenarios:
Controlling grow lights
Program a standard 18/6 or 12/12 light cycle once, then it runs all week without touching it. Scales from single fixture to multiple lights chained safely per outlet. The timer handles up to 1875W per outlet — enough for most LED or HPS setups in residential spaces.
Running extraction and circulation fans
Set one outlet to run fans during your light period, another to trigger a separate ventilation schedule if needed. Keeps temperature and humidity stable without manual intervention. Growers report this alone cuts energy costs noticeably.
Hydroponics and watering systems
Automate irrigation pumps with granular timing — run for 15 minutes every two hours, or whatever schedule your system needs. The 1-minute minimum interval gives you flexibility that mechanical timers simply can't match.
Seven-day scheduling options
Choose daily repeating schedules, weekday-only patterns, weekends only, or full seven-day custom sequences. Eight preset working-day combinations cover most scenarios without bespoke programming.
When you're away
Random on/off mode deters theft by making it look like equipment is in use at unpredictable times. Peace of mind that your setup is both secure and running.

- Budget-conscious setups where consistency directly impacts yield and saves energy costs
Particularly suited to spaces where reliable automation without complexity is the priority.
Our take
This is the digital 7-day timer we recommend most to growers serious about consistency. Twenty programs, dual independent outlets, large readable display, and a price that doesn't require justification to your bank. It does exactly what grow room automation should do — remove the variables and let you focus on growing.
Good time to buy while clearance stock lasts. Reliable piece of kit that earns its socket space from day one.
