I have read that clear helps warm the soil and gives seedlings a better start?
" 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🤷‍♂️
