AutoPot XL AV5 Grow Kits

AutoPot XL AV5 Grow Kits - Pump-Free Watering for Bigger Plants

Best for: Growers stepping up to larger 25 litre pots who want consistent, hands-off feeding across several plants without running a pump or timer.

The AutoPot XL AV5 Grow Kit is a gravity-fed watering system built around AutoPot's AQUAvalve5, sitting inside 25 litre XL pots. Each valve draws feed from a central reservoir and tops the tray up to a fixed 20mm depth automatically, then shuts off - no pump, no timer, and no electrical equipment anywhere in the system. Kits link together using 6mm (9mm external) feed pipe, so you can run a run of pots off one reservoir, and each individual pot still self-regulates its own watering.

The AV5 valve is an upgrade on earlier AutoPot generations, with a 5mm fill hole and wider inlet that resists blockages from thicker or particulate nutrient solutions - useful if you're running organic feeds rather than clear minerals. Because the whole system runs on gravity, it also keeps working through a power cut, which is more than can be said for pumped systems.

How it compares

AutoPot occupies its own corner of the market as the main pump-free, gravity-fed system UK growers reach for.

• Nutriculture's Wilma systems use a pump and timer to flood-and-drain trays - more control over feed timing, but another point of failure and a mains socket to find.
• GHE's Aqua-style flood systems work on a similar recirculating principle to Wilma, again needing electrics.
• Compared with hand-watering the same number of 25L pots, AutoPot removes the daily watering can round entirely, at the cost of needing a level surface and a topped-up reservoir.

If you want plants fed automatically without wiring anything up, AutoPot is pretty much the category leader - the trade-off is a bit more plumbing to set up at the start.

Usage guidance

The system is straightforward once it's level and plumbed in correctly.

Levelling
Each pot and its AQUAvalve need to sit on a level surface - even a slight lean stops the valve reading the correct water level, which leads to overfilling or a dry tray.

Connecting the reservoir
Run 6mm (9mm external) feed pipe from your header tank or reservoir to each AQUAvalve. Multiple pots can be daisy-chained off the same tank using T-pieces.

Topping up
Check the reservoir level every few days depending on plant size and stage - the valves will keep pots fed as long as there's solution in the tank.

Mixed feeds
The AV5's wider inlet copes better than earlier valves with thicker organic nutrients, but it's still worth giving any feed a stir before it goes in the tank to avoid sediment settling near the valve.

Technical specifications

• Pot volume: 25 litres (XL pot)
• Valve: AQUAvalve5
• Fill depth per cycle: 20mm
• Feed pipe: 6mm internal / 9mm external
• Power required: None - gravity fed
• Kit sizes available: Multiple pot-count configurations
• Compatible reservoir: AutoPot header tank / FlexiTank
• Material: UV-stable polypropylene pots and trays

Who this is for

• Growers scaling up from small pots to bigger 25L containers
• Anyone running several plants who doesn't want to hand-water each one daily
• Growers who travel or can't check on plants every day
• Organic growers wanting a wider valve that copes better with thicker feeds

Best suited to a grow room or greenhouse set-up on a level floor with a reservoir close by.

Our take

This is proper, well-proven kit - AutoPot's passive watering system has been around for years precisely because it works without asking much of the grower. The XL AV5 kit just brings that reliability to bigger pots and bigger plants.

If you're tired of watering rounds and want a set-and-forget system that doesn't need a pump, this is worth picking up. Does exactly what it should, day in, day out.
