When sun shade net is set up, it can be propped up, leaving a gap of about 20 cm apart from the plastic film. Thus forming a ventilation belt, the effect of sunshade cooling is better.
When using of external sunshade net, it needs to consider whether the thermal shrinkage of shade net is stable. If the thermal shrinkage is unstable, it may cause damage to the bracket and the clamping groove, or tear net shade . If you are not sure whether the thermal shrinkage is stable, you can try it on a small area first.
In addition, if the thermal shrinkage is too large, after using for a period of time, shade rate of net will increase. The shading rate of net is not the bigger the better, because too high shading rate will reduce plant photosynthesis, so the stems will become weak.
