Our mini greenhouses are a complete growing system, with built in watering. Pipes are integrated with the shelves and aluminium frame, and connected to electrically operated water valves. Water is provided by either a pump (which goes into a small water tank or a nearby water butt) or a garden hose.
All models feature two separate watering zones; top and bottom. The top of the greenhouse is intended for starting seeds and low plants such as salads. This area is covered by misters / sprayers. The bottom of the greenhouse is intended for larger plants, and is covered by sprayers with a larger nozzle size.
Water pressure is provided by a small submersible pump (280gph, 12v, 45mm diameter) which drops into a tank or water butt next to the greenhouse. No priming is needed, which allows us to control the pumping time more precisely, knowing that the plants will actually be getting water rather than the pump just running to prime itself.
