Achieving day/night temperature differential indoors

[mremensnyder]

Ray,

I see what you are saying. I did think about increasing rather than decreasing the temperature. Then you would have 70F-75F at night and perhaps 80F-85F during the day. This should be fine (perhaps not 100% ideal) for most paphs. Then in the winter, the dedicated room could be lowered accordingly.

I actually tried Peltier cooling a number of times and could not make it work well for any length of time. I had a terrarium consisting of a bottomless 10 gallon fish tank on top of a thermoelectric cooler with the top removed. The two were glued and taped together. It actually worked ok but I had to replace the whole cooler every couple months since it would burn out from having to run so inefficiently with the top off.

I also kept telipogons in a fridge for a while back in 2011. This worked quite well.

For Paphs, I would need a bit more space than either of these options would allow. Controlling a whole room of the apartment seems like the way to go.
