One of the many great aspects of hydroponics is the amount of environmental control you can have over your hydroponic garden. One necessary tool is the hydroponic timer, a must-have for any hydroponic garden, especially one that’s indoors.

Here’s what you need to know about hydroponic timers for your garden.

How Timers Are Used To Control Aspects of A Hydroponic Garden

Timers can play an important role in a hydroponic garden. Depending on how your garden is set up, a hydroponic timer could be used to control several different aspects of your hydroponic garden.

Most often timers are using to control the lighting of a hydroponic garden. Plant varieties vary on the amount of light needed and light duration often needs to be changed during the course of the plant’s growth cycle. Using a hydroponic timer allows you to set up a perfect lighting schedule, turning your lights on and off at specific times.

A hydroponic timer can also be used to control when and how often your ventilation turns on and off.

Another area where a timer may need to be used is to control the nutrient flow intervals of the hydroponic garden. Some hydroponic systems, like ebb and flow systems, can be set on timers to flood the grow bed on regular intervals. Using a hydroponic timer can allow you to regulate how often and also how much your hydroponic garden is watered.

Here Are My Top 5 Hydroponic Timers 

My Top Hydroponic Timer Pick

Geeni Surge 6-Outlet Smart WiFi Surge Protector

My top pick is a little unconventional because it’s not really a timer it all; it’s a power strip. Geeni Surge 6-Outlet Smart WiFi Surge Protector is WiFi enabled and can be controlled via an app.

The app allows you to not only control the power to each outlet but also set up schedules for individuals outlets. That features makes it possible to control several different aspects of your hydroponic garden with tool/ app. There are also several other Geeni products such as single plugs, lights, cameras and alarms that can be added to and controlled by the app as well. This Geeni surge protector can not only control the main aspects of your hydroponic garden, but with add ons can be used to visually keep an eye on and monitor your whole system. The fact that you are given more control over your garden without having to purchase expensive automation equipment makes this 6-outlet/timer my top pick.

    Great article, I have always used the plain mechanical, which I found more reliable than the digital rail timers. Now, I only rely on my Raspberry zero. All parameters( temps, humidity, soil moisture,light,EC,PH, etc, logged to Dbase and by using a fairly simple Python app, I can time limit, and switch all devices, from lighting, misters, irrigation, ventilation by switching relays according to pre set levels. Runs on Solar, so no spikes or downtime. With the added advantage of been able to login remotely to see and intervene all parameters. All this at a great cost and learning a great skill as a bonus.
