I put black plastic down on my raised beds last week, and have seedlings that desperately need to get outside (roots are poking through the bottom of the pots in my living room!). I am planning on putting them in the raised beds with cover (PVC arches), but am confused about clear plastic vs row cover (especially since the temp is going to fluctuate so much-almost 80 tomorrow, 50s this weekend). I want to keep them warm, but don't want to "cook" them. The plants are cucumbers, squash, melons, sunflowers.

Any tips? TYIA!

I think if you use plastic when it's 80 degrees, your plants are going to get overheated. I think it would be OK with temps in the 50s with just row cover.

I have glass cloches I've tried to use other years. They will fry plants in nothing flat. If you use them, be sure to have something underneath them to elevate at least one side. Sometimes I've put them up on blocks so they cover the top but have plenty of air circulation.
