Producing cucumbers when temperatures exceed 30C (86F) can be challenging in conventional houses especially when outdoor humidity levels are high. We have proven that it can be quite easy to grow 3 crops of cucumbers in warm and hot climates (12 months per year) even when outside temperatures exceed 39C (102F) by using a retractable cooling house with a stationary or retractable layer of insect net under the retractable roof

The insect net under the roof helps provides a stable microclimate that is free of insects helping to reduce losses from virus. Retracting the net can be helpful during the winter to help increase light levels and leaf temperatures.

The retractable roof being installed above the insect net helps optimize leaf temperatures and humidity levels inside helping prevent the foliar diseases. The roof will be used to help cool by blocking sunlight midday helping to prevent the heat from entering below the insect net. The retractable roof will also be used to protect from rain, cold and dew.
