MetryGrow Automatic Watering System for Potted Plants — Black, Programmable Timer, 10‑pot Drip Irrigation

MetryGrow’s Automatic Watering System is a programmable drip-irrigation kit that delivers precise, low-pressure watering to up to 10 potted plants so you can maintain healthy containers while away or on busy days.

This compact self-watering solution pairs a quiet pump and an easy-to-use LCD timer with drip emitters and check valves to create a reliable, low-waste irrigation loop for balconies, offices, greenhouses, and grow tents. The controller supports both battery and USB-C power, offers delay and manual modes for flexible conditions, and lets you schedule run times from seconds to minutes and frequencies from hourly to weekly.

How simple is it to program watering schedules?

Setting up customized watering cycles is straightforward thanks to the clear LCD and intuitive button layout. You can define start and end times, pick duration from 5 seconds up to 30 minutes, and set frequency between 1 hour and 7 days, then let the timer follow the plan automatically.

• LCD display with simple buttons for fast configuration
• Start/end times plus duration and frequency control
• High-precision timing chip for consistent execution

What happens if the weather changes or I need one-off watering?

The unit includes Delay Mode to pause scheduled watering—useful on rainy days or when soil is already moist—to avoid overwatering. Manual Mode lets you trigger an immediate watering cycle whenever plants look dry, adding flexibility without reprogramming schedules.

• Delay Mode suspends automatic runs when moisture or conditions dictate
• Manual Mode adds instant watering sessions on demand
• Modes work together to reduce water waste and adapt to changing conditions

Will all my pots receive even water distribution?

The system is engineered to preserve stable pressure and steady flow so each drip emitter provides consistent output across multiple pots. The quiet pump achieves up to 24 L/H and about 4 PSI, while one-way check valves help avoid backflow and accidental siphoning.

• Stable pressure design for balanced multi-pot delivery
• Drip emitters target root zones to improve efficiency
• Check valves prevent backflow and keep lines primed

How long will the controller run and what power options are there?

MetryGrow’s low-power chip minimizes energy use so four AA batteries can power regular schedules for months, depending on runtime. For unlimited use and to preserve batteries, plug in a Type-C cable for continuous operation; the wired input also helps maintain precise schedules without interruption.

• Exclusive low-power chip for extended battery life
• Dual power: four AA batteries or Type-C USB-C wired power
• Type-C keeps schedules steady and reduces battery cycling

Who is this for? The MetryGrow Automatic Watering System suits plant owners who want a low-effort, reliable way to keep multiple potted plants hydrated—ideal for frequent travelers, busy professionals, balcony gardeners, small greenhouse operators, and indoor hobby growers. It’s especially helpful if you need programmable precision across several containers without installing permanent irrigation lines. The kit’s modest footprint, flexible power options, and per-pot drip delivery make it a practical choice for apartments, offices, patios, and grow tents where consistent moisture management matters but space and noise budgets are limited.
