Cute! I considered under-the-sink too once... decided to risky since strangers/visitors/boyfriend would be more likely to open a sink cupboard then my current cabinet, a dresser. I would totally LST too... I'm growing Holland's Hope right now and LSTed them all along, they're no more than six inches tall and a few weeks into flowering now. 'Course I'm running out of sideways room to stake 'em... might just let 'em go now and move my lights up a bit once they get to that part. Good luck!
