Clear Vs White Greenhouse Plastic

Clear vs white greenhouse plastic

If your growing area needs more sunlight, it's beneficial to use clear plastic because it diffuses light and reduces the risk of sun damage to plants. If you need to control temperature or light, you may consider a white greenhouse or a light deprivation cover to reduce heat and reflect UV rays.

Should you use clear plastic for greenhouse?

If possible, find a location where the greenhouse will be getting at least 6 hours of direct sunlight per day during the winter.

Does white polycarbonate turn yellow?
