We've had a lovely couple of days here so today I thought I'd put my young seedlings outside (they're a couple weeks old). They didn't get much direct sunlight, maybe about 15mins of it. There is a breeze, but nothing major today. After being outside for a couple hours they're wilting. It's not every single plant, but many of them. Especially the cucumbers and peppers. Is this because it's not warm enough for them or because of the breeze? Is it likely they'll survive, or could the couple of hours outside have killed them? The temp today is 20c (68F).
I've now brought them inside and put them under a light to give them a break. Normally I have them in the sunny window, but I don't want to do anymore damage to them.
