I guess the most likely is when you had it at your home you had some source of light interfering with your plant (from your house, street lamp or somethin like that) & when you move it the light hours reduced & that's what triggered flowering.
About your Q, i have heard about this kind of harvest but i have no personal experience & never really searched it. If no one answers you why don't you google it & see what you can find out. In my eyes though (inexperienced grower) it seems that you're gonna stress it a lot that way.
