The towers are constructed out of PVC stormwater pipe, with a polyurethane irrigation pipe down the center which drilled with small holes.

The irrigation pipe is connected to a water timer to ensure quick but very regular watering. You have to wrap the irrigation pipe in weed-netting to stop the strawberry roots from blocking the holes.

The towers are secured in a large pot with about 20 kilos of concrete. This is enough to ensure the tower remains standing in wind gusts as strong as 130km/hr. - initially we used terracotta pots, but these cracked over time, and some broke when the towers toppled over in gusts greater than 130km/hr. We are trying out plastic pots now.
