PICK YOUR OWN
This controller looks great about how much $$ no price when I followed the link...unless I missed it....This is what I use in my main flower room controlling my HLG 650's. Has a sunrise and sunset feature if you want to use that and will also dim the lights if the temps get too high at your desired setting. And this has come on a couple times with me. My air-conditioning doesn't always like to come on like it should. I have the air set at 86 and the dimmer on 91. I could prob move it up more and still be safe since I have high humidity in my room.
