I'd say only give them one hour on their first day out.

I'd put one of each species out for a couple days and see what happens. I've noticed that if I keep the propagator at 72-77 degrees, and under lights, the seedlings grow much more quickly than with a 55 degree temp and natural light in the GH.

We're having a warm and sunny day here as well (already 70). I put mine out on the front porch, which is covered. They can have some morning sun, then sit in the shade for the rest of the day. I wouldn't trust them in direct peak sunlight though.

I think basically you follow "Hardening Off" procedure. So you introduce them to sun gradually. Once that is done, they can take it all day.

I started doing that with mine now. What a pain with so many boxes packed with chili's. If it stays warm like this I may be able to move them soon into the GH. Nights maybe hit 50 here.

Not sure a window makes too much of a difference. The sun heats the soil and the plants still get light.

Ronny ... I would move mine out if the night lows stay over 42? I have to wait til July if I want 50f lows.

I use a cold frame, it gives you 20-30 degrees. So mine are out in Michigan already. I agree when below the 50's putting them outside does little good. I would say even stunting them. I have to bring in at night. I follow hardening off procedures at first. We are hitting 50F so it's 70- 75F in the cold frame. When temps hit 60F I have to vent cold frame. As it can get to be 90F.

Peppers just explode when grown at the right temps. If you have grown them a bit you must have noticed when temps reach a certain level, they just grow like crazy, well it can be done a lot earlier with a cold frame. Those exposed to colder temps seem to be slow to get going, at least that is what I have observed. Tomatoes can take more cold, but I try to avoid it with them too.

Well it's 25 F right now, when it warms to 45F I'll put them out for the day (65-75 in cold frame).
