PLANT!T Battery Irrigation Timer – Automatic Watering for Gravity & Tap Systems

The PLANT!T Battery Irrigation Timer is the ultimate control unit designed to automate your watering system without relying on a plug or complex wiring. This device connects easily to both standard taps and gravity-fed water tanks, giving you the freedom to keep your plants hydrated with surgical precision while you focus on other things.

Why you need to automate your irrigation now

Problem: Let's be real, hand-watering is a hassle. You have to be there every single day, at the same time, or your plants get stressed. If you want to go away for a weekend or just have a busy day, your indoor or outdoor grow suffers. Plus, relying on memory often leads to inconsistent watering—drought one day, a flood the next.

Agitation: This inconsistency is the enemy of a big harvest. Water stress stunts growth, reduces yield, and can even kill your crop if you forget for too long. And let's not talk about the back pain from hauling buckets or the anxiety of wondering if your plants are dying while you're at work. It’s a vibe killer.

Solution: The PLANT!T Battery Irrigation Timer solves this instantly. It acts as the brain of your operation, delivering the exact amount of water at the exact time you set. Whether you are running Drip irrigation systems or a simple hose setup, this timer ensures your plants are happy, healthy, and fed, even when you aren't there.

Before using this timer in your grow

Setting this up is super chill, but you need to have your rig ready. Since this timer works with zero pressure (gravity) and up to 10 bar (tap), you first need to decide your water source. If you are using a tank, make sure it's elevated enough to get flow. You'll need two high-quality AAA alkaline batteries—don't skimp here, cheap batteries are a risk to your crop.

• Check the filter: The unit comes with a built-in filter; ensure it's clean to prevent clogging from tank debris.
• Vertical installation: Always install the timer in a vertical position to ensure the valve mechanism works smoothly.
• Battery quality: Use brand-new alkaline batteries to ensure the maximum lifespan (usually a full season).
• Fittings: It comes with a 3/4” female connector for the tap/tank and a male snap-on connector for the hose. Make sure you have the right adapters if your pipes are different.

During use: Precision and Peace of Mind

Once you dial it in, the magic happens. The interface is incredibly intuitive with two dials: Frequency (how often) and Run Time (how long). You can set it to water every hour for high-drain hydro setups or once a week for cacti or maintenance. The duration ranges from 1 minute to 120 minutes. This flexibility is perfect for Urban Gardening on balconies where you might need frequent, short bursts of water to avoid runoff.

A killer feature is the safety valve. If the battery runs low, the valve automatically closes. This means you won't come home to a flooded room or an empty tank because the timer died while open. Also, if you need to do a manual check or mix in some Cannabis fertilizers, the delay/pause function allows you to stop the program without resetting everything.

After: Results and Maintenance

After a full cycle with the PLANT!T timer, you'll notice your plants are more vigorous. Why? Because plants love routine. Consistent moisture levels lead to better root development and fatter buds. You also save water and nutrients by not overdoing it.

Maintenance is minimal. When the season ends or if you're expecting frost, disconnect the timer and bring it inside. Freezing water expands and can crack the internal valve. Remove the batteries if you store it for a long time to prevent leakage corrosion.

Frequently Asked Questions

Does this timer work with a water butt or tank?

Yes! This is one of its best features. It operates with 0 bar pressure, making it perfect for gravity-fed systems where you just elevate the tank slightly above the plants.

Are batteries included?

No, you need to buy two AAA alkaline batteries separately. We recommend high-quality ones to ensure they last the whole season.

Can I leave it out in the rain?

The unit is weather-resistant and designed for outdoor use, but it comes with a protective cover for the dials. However, always bring it inside during freezing winter temperatures to prevent frost damage.

How do I know if the batteries are dead?

The unit has a safety feature that closes the valve when power is too low to operate, preventing continuous flow. If it stops watering, check your batteries immediately.

Personal Experience of Pevgrow’s CEO (Alan)

I've tested a lot of timers, and honestly, most cheap ones fail when you use a gravity tank because they need pressure to open the valve. The PLANT!T is different. I use this specifically for my mother plants when I take a summer trip. I hook it up to a 50L tank, set it to water for 5 minutes every 24 hours, and I sleep like a baby.

My pro tip: Even though it's weather-resistant, I always wrap a little plastic bag over the top if it's going to rain hard, just to be double sure. And always, always use new batteries at the start of a grow. It’s a small investment that saves you a lot of headaches.
