Cold outside, what to do?

Personally, I would leave it outside in full sun. Bit cold, but warmer in direct sun, however I would bring it under cover at night. It will still grow, just a bit slower, but better than a stretched, weak and spindly indoor plant that isn't getting enough light. Besides, the weather will warm up soon enough. Hope this helps,............ Organoman.

The temp is too low, better inside near the window for now.
