What up PC! If I were you, i would leave them alone and not mess with 'em. Even on an overcast day they are getting more lumens and uv light than you could ever supply indoors, not to mention they always take a little time to readjust to a new environment, so I don't think you would really gain anything. And there is always the risk of you bringing outdoor pests, spores, bacteria, whatever, into your house. I say just leave 'em and let mother nature do her thing, just help her out a little along the way. Feelin' me?
