Probably been covered but what ideally should I be aiming for in terms of watts per square (or cubic) feet during veg, presuming everything else (temp, rh, etc.) are dialed in? I presume I should be bumping it up to near 50 watts per sq ft (or to whatever I'm running in flower) before I flip, but how much is overkill, and how many watts should I be running during each week, etc.?
