Can you use clear glass for greenhouse?
The main disadvantage of using clear vs opaque or frosted greenhouse plastic is that direct light creates hot spots while leaves other plants in shade. It also produces excess heat that is trapped in the greenhouse. In a meantime opaque plastic scatters light waves and provides even light for optimal plant growth.
Is clear plastic OK for greenhouse?
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.
