Function: energy saving and heat preservation; control photo-period
Features: fully enclosed sunshade; easy to fold
In order to control the photo-period, the double-layer SI-CW/CB has a light blocking rate of 99.9%, which is also suitable for the most sensitive plants. The upper layer is made of white material for better cooling effect. Its unique weaving process reduces the influence of condensation, and the volume is small after folding, which does not affect light. This kind of screen is stable to ultraviolet rays, keeps clean, and has a long service life.
