Okay, I now have a total of 4 incubators of the Styrofoam ilk: two Hovabators and two LGs. They work okay, but the external temp has to remain fairly constant it seems which means I have to run the AC when it gets warm even when I am not there. They all sit right under the house thermostat. That seems wasteful and expensive to me. They all have wafer type or similar thermostats. I'm wondering if these new cabinet incubators with digital thermostats are any more efficient, less finicky. Do they allow for a little greater variance in external temps? To the extent I might not have to turn the AC on when I am gone? Would it eventually pay for itself vs. these cheap jobbers by saving electricity? Of course, clever souls that you are will no doubt see past my evil plan and know I'm really trying to justify the expense of a brand new fancy digital cabinet incubator. Thanks in advance for the enabling.
