Thermostats?

[Reakt20]

I currently use an on/off thermostat that I purchased at a local grow shop and I would not recommend going with these types. The one I am using is the Custom Automated Products TMP-DNe. It has 2 knobs, one for day and one for night. It finally has stabilized but for a while i was getting very large swings in temps. I was constantly turning the knobs to get it under control and nothing would hold. I don't know what happened but everything now stays around 94 with an average 3 degree swing so I don't touch it anymore!
I am saving up for a herpstat 4. That is the cadillac of thermostats, imo. Shouldn't be too much longer until the one I have ends up in the back-up box.
