In order to prevent the insects into the greenhouse, we usually install insect prevention net in the air vents. Insect prevention net can keep insects out of the planting areas, can protect the plant without using pesticides or using less pesticides. It's a new way of environmental protection and is conducive to the sustainable development of agriculture.

At present there are three kinds of insect prevention net in order to meet the requirements of different plant. One is silver-gray or aluminum foil one, its expelling aphids effect is good and can reduce the temperature in greenhouse; the second is the white one, its light transmittance is much better than the silver-gray one and more widely used, it's suitable for photophilous plant, but in summer, it will raise the temperature in the greenhouse; the third is the black one, it can prevent insect and have sunshade and cooling effect.

Install the insect prevent net in the air vents of greenhouse will obviously add the ventilation resistance. To install it in the period of pests and keep monitoring the temperature in the greenhouse is necessary. When the period of pests past, it's better to dismantle it.

If the period of pests is the same period of greenhouse need ventilation and cooling, It's better to pay more attention to the following points:
1. Increase the insect prevent nets area or vent area to ensure adequate ventilation. Using nets and rolled polyethylene film instead of hard polyethylene wall is the good natural ventilation method to increase ventilation rate;
2. For the greenhouse which has ventilation, it can install the prevent nets only in the air vents;
3. Keep clean the surface of the prevent nets.

We provide after-sales installation and debugging, Skyplant's engineers could service at site. But, please note this cost is not included in the quotation.
