Greenhouse watering system electric (Gedling NG4)

Works with electricity. Automatically fills pots and empties them with water and feed. The timer doesn’t seem to work but that couldi probably be replaced. Made in Nottingham.
24 pots and outer containers, 2 water butts 70 litres which are joined together. All wiring and pumps. Working order. Requires a large, flat floor area for all the pots to spread out. The brain part needs to be kept dry.
I used it in a greenhouse to grow tomatoes but versatile. The feed is put directly into the water butts so the plants are fed at the same time as watering.
The tubs are filled with a hosepipe.
