Choosing between greenhouse, shade house and net house
A plastic-roofed greenhouse keeps rain off tomato leaves but can run 8 to 10 degrees hotter than outside by midday, while a shade house or insect net house stays cooler but lets rain and some pests through. Picking the type to suit the crop, the district's rainfall and the budget is the decision every later cost depends on, so make it on paper before talking to a builder.
First tasks
- Write down the crop you plan to grow under cover for the next three years
- Ask the extension office for two growers running covered structures nearby
- Visit both houses at midday and note how hot it feels inside
- Record the structure type you chose and why in the record book
