I have started this seasons crop and plan on growing them in my greenhouse. My question is, even in the greenhouse the temps drop close to outside temp at night. I’d like to keep the seedlings outside but outside temps will get to about 40F overnight. Is this too cold?

U got it growmie!
Here’s to a killer season! 
Use a heat mat or some type of bottom heat if possible, at 40F growth may be slowed a bit.
I think plants can usually take freezing temps pretty well, even not in a greenhouse, but frost/moisture is what will kill em fast.

Yeah in the greenhouse it’s protected from frost, and the 40 temp are only for a few hours… maybe 6-8 hours?

How about seedlings in the desert like seeds breaking dirt today? @AzSeaindooin420 @DesertHeartGardens
Also super dry hot wind should I use clear cups or humidity done? Have seedlings from 1-9 days above ground in pots.
Going to be hard for any seedlings in this hot of heat @420noob I’ve had mine established for over a month now
