Shane has three large greenhouses. Two are 2000m ² greenhouses and a newer 1600m ² house with ridge vents which he built kitset-style. They are all unheated, so most of his crops are finished by May/june. The warmer autumns over the last few years have enabled Shane to carry crops a bit later. The springs have been cooler, but with fewer frosts, he has been encouraged enough to try marginal crops like okra. Over winter he rotary hoes sheep manure into the soil, covers it in black plastic and lays sawdust on top, which is later recycled. T-tape irrigation supplies water to all the plants.
