i think its possible, you can grow bonsai sideways by wireing it that way so i think it could be possable and there are air purifires that can get rid of any smell under your bed and i bet there is a way you could rig your lighting which if you were to put it on a timer could be turned on and off periodicly to cool. so i think its a pritty fucking good ideas you sightless nay sayers. i think that the major factor would be how much space you have under your bed and how confident you are that no one will look there. I am pritty confident that it would work if you put enough effort into it and didnt say its impossible because there may not be an easy to see obveous answer.
