AutoPot 1 Pot Module with 3.9 Gallon Plastic Pot and No Tank - Self-Watering, Gravity-Fed Hydroponic System (1Pot - 3.9 Gallon - No Tank)

Just what you need connects right up and worked flawlessly.

Easy to use. Quality is great. I wish the price was worth the minimal effort into making these.

Didn't work out for me. Had nothing but problems with the valves. There are way cheaper and easier ways to set up an automatic watering system.
