AutoPot Watering Systems UK

Choosing an AutoPot watering system

Start with the root volume and number of plants. The easy2grow tray holds two compact pots side by side and suits tight spaces. A 1Pot module gives each 15 litre pot its own tray, so you can spread plants around a room. The 1Pot XL increases root volume to 25 litres. FlexiPot and XXL modules suit growers who want fabric pots and larger root zones.

Every module still needs the right reservoir, pipework and filter. Current AQUAvalve5 systems use 9mm supply pipe at the module. We also stock 6mm parts for older installations. Check the valve and pipe generation before ordering a replacement fitting; similar-looking connectors are not interchangeable.

How gravity-fed AutoPot watering works

Raise the reservoir so gravity can move solution through the supply pipe. The AQUAvalve5 admits a shallow level into each tray, then closes. It does not reopen until the plant has used the available solution. That plant-controlled cycle removes the need for a timer and avoids pumping nutrient solution around the room.

The tray must sit level and the AQUAvalve must be fixed firmly into its tray fitting. Keep loose growing media away from the valve chamber. Fit the correct in-line filter at the reservoir and clean it regularly. These simple checks matter more than adding extra pressure.

Reservoir size and nutrient choice

A larger reservoir changes temperature, EC and pH more slowly, but it still needs routine checks. Size it for plant count, root volume and the number of unattended days you need. Our hydroponic reservoir sizing guide gives a practical starting point. The water-change guide explains when to top up and when to replace the full solution.

Use a clean, fully soluble mineral nutrient for the simplest setup. AutoPot allows suitable organic liquid feeds with AQUAvalve5 and 9mm pipework. Organic feeding needs extra circulation and cleaning. Follow the feed maker's instructions and the current AutoPot nutrient guidance. Never leave thick or settling feed in narrow pipework.

A compact two-pot starting point

Best for: two plants sharing one AQUAvalve5 tray.

The easy2grow system keeps the footprint small and can be extended later with matching modules.

What else will you need?

• Reservoir: match the capacity to plant demand and refill interval.
• Filter: use the correct size for the tank outlet and supply pipe.
• Pipe and fittings: confirm 9mm, 6mm or 16mm before ordering.
• Root control: fit the correct disc or PotSock for the chosen module.
• Meter: monitor EC and pH when feeding mineral nutrients.
• Shut-off taps: isolate branches when cleaning or removing a module.

Read the nutrient, pH and EC guide before mixing a new feed. If the reservoir pH keeps rebounding, use our rising-pH diagnostic. For pumped dripper systems rather than valve-fed trays, compare the irrigation systems range.
