" There are many benefits to using a diffused plastic covering for a greenhouse.

Clear panels deliver direct light while opaque panels provide diffused light. If you want to germinate seeds and grow starters which will be transplanted outdoors, then a clear covering has the advantage of bringing full, direct light to the starter trays. This warms the soil and encourages germinating seeds to sprout and develop into a vigorous starter plants for transplanting.

If you plan on growing the plants to maturity in a greenhouse, a diffused covering has the advantage of providing even light for balanced foliage growth as well as preventing hot spots within the greenhouse."

I see the above quote everywhere while researching🤷‍♂️


I guess one can find just about any opinion since everyone has one. nodding My experience tells me that diffused works just as well both in providing adequate light and warming the soil. It is the temperature of the greenhouse that warms the soil, not the sunlight. Also, with clear, you run the risk of burning tender plants; the opposite is true with diffused light. I would be interested in what you decide and your results.
