I made my stand whit 2" extra on sides and made a canopy,it stands in the extra 2"; I have 2 lamps, 2 bulbs each, because was cheaper than buy the 4 bulb lamp, also u can set diferent timers, I got 2 dayligths and 2 gro-lux. The lamps were on sale for 10 and the 4 bulbs for 22, so I paid around 30 for my set up. and 10 for the 2 timers.
