It is for growers who want big plants, a tighter footprint and less faff than running three separate XL trays, and who are happy to feed it from a tank (not included). The pots, valve, pipe and fittings are all in the box.\u003c\/p\u003e\u003cp\u003eThere is nothing to plug in and nothing to programme. The plants drink the nutrient solution in the tray and the AQUAvalve5 tops it back up from your tank.

The tray, lid, AQUAvalve5, three 25L pots, a metre of 9mm pipe and the small fittings are all in the box, but there is no tank. AutoPot's minimum for a single Auto3 XL is a 50L FlexiTank. Pick a free-draining medium such as coco or a soil and perlite mix, and steer clear of thick organic feeds that could clog the valve.\u003c\/p\u003e\u003ch3\u003eDoes the AutoPot Auto3 XL need a pump or electricity?\u003c\/h3\u003e\u003cp\u003eNo. It is gravity fed, so there is no pump, timer or plug to worry about. The single AQUAvalve5 tops the tray up from your tank as the plants drink, and because gravity does the work, the tank needs to sit higher than the tray.\u003c\/p\u003e\u003ch3\u003eHow do I connect more than one Auto3 XL tray to one tank?\u003c\/h3\u003e\u003cp\u003eRun pipe from the one tank to the AQUAvalve5 on each tray. AutoPot's minimum tank sizes are 50L for 1 tray, 100L for 2, 225L for 4, 400L for 8 and 750L for 10. Only 1m of 9mm pipe comes with each tray, so you will need extra pipe and the right connectors for your layout (16mm is the other pipe size AutoPot lists).
