wellp.. it seems you have 2 choices.. first question i ask you is how many weeks into flowering and how big are the plants? if they are not too far along then maybe you can just leave em out and harvest in the fall.. which would be a good option yield wise.... or if you are in dire need of weed or just gotta finish em up your plants will still like the sun more than those little lights BUT you MUST MUST MUST keep them on a 12/12 schedule if not they will go back into vegitative state and outgrow the buds and in some cases go hermie if you forget to bring em out.. if you can bring em in or cover them completely without overheating them EVERY DAY AT THE SAME TIME then you will be fine and they will just resume where they left off...:hippy:
