I don't, but I have had luck just putting my fan on a timer and running it concurrently with the MH lighting, or a little longer. I was getting temp fluctuations of several degrees before trying this, but now the temp stays between 79-80 degrees 24/7.<a href=showthread.php?s=&postid=13019564#post13019564 target=_blank>Originally posted</a> by NicoleC
Anyone have a temperature controller they want to sell? I just need something to control my fan over my tank.
