>>999320>do I need to slowly adapt them to being non-bottled?(like a transition)No, you only need to harden them off if you are putting them outside. That will help prevent sun scalding of the leaves. Merely repotting properly or allowing them more room in the same environment shouldn't harm them.
>>999348Thinning is even worse. A least you know yours is in good health and should recover nicely. Keep us posted on its progress. I've never done that with my pepper plants and I'm interested in seeing how it progresses. I've only ever trimmed mine when I overwinter them inside. (reposted pic)
