LOL I just started tanning and when I saw the huge stand up bed the first thing I thought of was how well I could grow a plant with that setup! I know for a fact that if I spend alot of time in my Flower room under my 1000w my head feels sun burnt and I am not bald. So I would imagine that you could tan but may take a lil while. I know the tanning beds are high intensity bulbs and I doubt your floro bulbs are the same as the tanning beds.
