An irrigation timer is the perfect solution for anyone who wants to reliably and regularly supply their plants in a grow tent with water. Especially combined with drip irrigation systems, pumps and tanks, a timer ensures your plants always get the right amount of water and nutrients – entirely without manual watering.
An irrigation timer switches your pump on and off automatically, so your plants get water at fixed moments even when you're not around. Currently you'll find the SMSCOM STC Nutrimatic Timer here, designed for controlling pumps in hydro, coco and drip systems up to 2000W. Short, frequent cycles suit coco and drippers; soil usually needs fewer, larger waterings. Test your schedule for a few days and check run-off before relying on it fully. Combine the timer with a pump from submersible pumps and a reservoir from flexible water tanks.
Questions & answers about Irrigation Timers
All growing questions →- Water, pH & EC How often should I change the water in my reservoir? In recirculating hydro, every 1 to 2 weeks. In soil or coco you mix fresh feed for each watering, so there is nothing to change. Read the answer →
- Water, pH & EC What is the ideal water temperature for my plants? Roughly 18 to 22 °C. Colder water slows the roots, warmer water above about 24 °C makes root rot much more likely. Read the answer →
- Medium & pots How often should I water in soil and in coco? Soil: water when the pot feels light and the top 2–3 cm are dry. Coco: water small amounts often, daily or every second day in bigger pla... Read the answer →
- Water, pH & EC Can I use tap water, or do I need reverse osmosis water? Tap water is fine if it's moderately hard (EC below roughly 0.8). RO water is a blank slate for exact control, but you must add Cal-Mag. Read the answer →
Advantages of an Irrigation Timer
Automation: no more daily manual watering needed. Precise control: intervals and duration can be set exactly. Optimal plant growth: even supply prevents drought stress and overwatering. Time savings: ideal for larger indoor projects or when you're away. Flexible: suitable for soil, coco, hydro and other substrates.
Use in Indoor Growing
An irrigation timer is simply installed between the pump and the power source and controls water flow according to preset times. This lets you:
Set irrigation intervals for different growth phases. Deliver nutrient solutions specifically and regularly. Run automatic systems in small grow tents or large grow rooms.
Particularly practical: combined with irrigation controllers, moisture sensors and pumps, complex systems can be built that run fully automatically.
Accessories for Irrigation Timers
Tanks & pumps: ensure a constant water supply. Hoses & drippers: dose water precisely. Filters & pressure regulators: prevent clogging. Cloning systems & propagators: benefit especially from controlled irrigation.
Buy an Irrigation Timer
An irrigation timer is the ideal addition to any automatic irrigation system. It ensures precision, saves time and creates stable growth conditions – whether in a small grow tent or a large grow room.
