I'm wondering what people think of using temperature controllers that cycle heaters on and off instead of the heaters directly as a thermostat. I find my temperature cycles up to about 3 degrees with my halides by the end of the day but the dumb part is often I still see the heaters cycling on and off a little. I'm hoping that a temperature controller would be more accurate for a thermostat as the it easily stays under temperature if I unplug my heaters.

So, I'm also assuming that they are a little safer than your typical heaters that could stick on and cuase a melt down. I'm using small heaters and multiple but one on full still pulls the temp up a few degrees when I've tested it and I'm sure it would keep climbing (I had to stop it!!)..

Any recommendations or personal experience for these would be appreciated. I haven't even started looking into them yet, I just know they exists.

Thanks for any help
