I got a 3 ft 4 bulb solar xtreme deep blue t5ho fixture from a local local guy it has a built in timer on it the thing is the ballest had went out and someone replaced it with a more powerful one the hooked it up to where one of the timers are for the fans and the other is for all 4 bulbs instead of 2 the question is would u trust running this on a timer while your not home
