I NEVER left my fan leaves (water leaves) on plants until I read that here . . . and now that I'm flowering, I find myself taking them off anyway, as they suck up a LOT of light I don't have to give THEM. It certainly opened up the lower growth to some light and thus, some hope of a few decent lower budz.
Had I left them, I certainly wouldn't have made this little MaMa.
