With these towers you can grow above-ground vegetables on your patio, in your Greenhouse or any Sunny warm place. All you have to do is hook up with electricity to run the pump. You put water in the tub and then it circulates every 12 minutes for 3 minutes. You have to plug it into a timer. These towers are all in good working order the pots on the tower I take apart for shipping. All made of PVC plastic and I will send instructions along. Pumps are included.
Excuse me but the shipping is to high contact me for shipping price. Sorry!
