I thought i had hardened by peppers enough before transplanting them outside but a couple of my larger plants are getting sunburn. I dont have a great way of putting them in shade other than completely covering them with a sheet or something. So my question is. Typically if a plant is getting sunburned what is the time it usually takes them to adjust to the new light source? My smaller plants are having no problem with the transplant as they had a much shorter time with artificial light. Also would covering them up for part of the day help at all?

sun Sunburn and bounce back

Im guessing when you live and how close to the equator you are, I would wait for a cloudy day or in the shade.
I wouldn't stress about it too much. It's the little guys you need to worry about more than the big ones.
Seeing that the sunburn damage has already happened, I would just ride it out now and let them recover on their own. Probably won't even take a week.

I would try to cover them during the hours of most intense sunlight. Since they're new transplants, they really need their foliage now - when they're trying to establish a root system. Frying off all the foliage is going to really set them back. They're going to have a hard time growing all new foliage at the same time they're trying to grow new roots. This might be a bigger problem with the cool night time temps we'll be seeing around here for the next couple of weeks. Those plants won't be doing any growing for quite a while.

oddly enough I have had sunburn with using the T5 high output bulbs. I have around 26k Lumens over 4.5 sqft of space. I ended up having only a couple of the older leaves get some white bleaching.
I've seen bleaching too, but only on a seedling that was mostly shaded by much taller plant. Despite everything, it will bounce back in a week or two. The much worse scenario is, that seedlings are all hardened and healthy, but the second you bring them out, slugs prune them for you - thoroughly. Last year, I've had peppers without leaves and tops when I woke up their second day outside. Took them at least 3 weeks to recover.
