At 4 weeks flower INSIDE, can I move OUTSIDE?

Hi!
I am at 4 weeks flower on one indoor plant (indica dominant Shark Shock CBD) under a single 400w HPS.

Our days are now just about 13 hours long where I live with mild temperatures. I have a few outdoor plants which are also beginning to flower, but I want to free up my indoor tent for a new project. Is it possible/safe/a good idea to put the indoor plant in my greenhouse outside? Or do I risk serious stress to the plant with the change in light spectrum and slightly longer days?

That is a good question

your talking . 12/12 to 13/11 . your good . some people actually do 13/11 indoors and some do 11/13 or 10 /14 , put the plant out side right after there night . so your better to keep them total dark longer before putting out side then having a longer day . extra dark no problems . extra light problems .

naw, just do it
