They were fine yesterday. Today they are black. Is my greenhouse too cold? Or too much Sun?

From my 2 seconds of research, I’m pretty sure that most plants like to be in temps from like 60-75F😂 so I would check what the average temp in your greenhouse is, and then if it’s too cold, I think that might answer your question. I think plants can survive a lot of sun

Could be the temp if it’s cold out, also could be burn from direct sunlight. If your plant isn’t acclimated to receiving full sun it will burn.

I know in my greenhouse things weren’t going great until I got some shade cloths. The sun can be too intense for them. I use a 50% shade cloth and it works great.

Thanks everyone. Got a shade cloth ordered. Hopefully I can save these babies
