Ok, so I have been vegging under 24 hrs of t-5 light for a few months, now I have to get a timer, that's Dum Dum proof. Need a good timer that is fool proof and extremely easy to use, had bad experience with one in past. Also does HD or wally world have timers that work?? Also what is the best time to set- up ur 12/12 shedule for security reasons,?
