help! heat shock, dry roots?

I went out to my patch today to dig some more holes and water my babies. I left them alone for 24 hours with wet soil and when i got back about an hour ago half of them look really sick with dry leafs. Im sure the problem was lack of water and possibly to muck heat ( ive been keeping them under a mini greenhouse. I just want to know how bad this will shock them.

I think your greenhouse overheated them. Where do you live? It's getting way to hot here in cali for a grenlenhouse

South pa. It did get in the low 80s today. I water the soil and sprayed water on the plants. Dont know if it going to help though

Thats one of the 35, thats the worst of them
