We've had a few cold nights where I live in Ontario, after some unseasonably warm weather. I have been bringing my plants into my partially insulated garage at night. The garage has a few windows but definitely doesn't get the proper amount of outside light.

One of my plants looks to have a few "hairs" near the main cola which I have very recently topped. Are these pistils? After tonight the nights should be warm enough to just leave the plant out. If yes, I assume the plant will go back from pre-flower to veg given the days are still getting longer for a few more weeks? Is this going to cause a large setback for the plant?

Also, I assume this means I have a female or hermi plant?
