I know which ever one it is ... I have it.. LOL
if you are changing light conditions it's best to do it slowly.. put it outside for a few hours and then put it back in.. adding time each day.. just like hardening off seedlings.. at this time of year I am not sure it will be worth it to move it outside.. too many cool nights will turn it to mush.. they are not happy unless it's over 50 all the time.. a plant light will help for sure
