Thanks, I plan on removing the bottles this weekend.

Rather than removing the bottles entirely, you could cut the top off so that
the plants sit in a collar. It'll give them some protection still but will
stop them from cooking. You already know they've liked the environment of
the bottles so keep it up for a little longer but in a modifed form. You've
still got babies there and babies like protection and cossetting.
