Your choice of power

If you have 240v electricity available, choose the mains powered option. If you don’t have power in the greenhouse or polytunnel, use the solar option.

Your choice of water supply

If you have mains pressure water at your greenhouse or polytunnel, choose the garden hose mode. Otherwise choose the pump model for a pressurised, high flow rate off-grid system which can run from a water butt or tank.
