Seasons' Temperatures

[girloy]

Hello there!

As I said on another thread I'm trying to implement a system that will somewhat simulate the seasons' different temperatures and daylight times.
I made some research and got this values:

All the temperature values refer to the hottest part of the terrarium.


Winter
Day Light: 12 hours
Night Light: 12 hours
Day Temp: 31 Cº (88 Fº)
Night Temp: 20 Cº (68 Fº)


Spring
Day Light: 13 hours
Night Light: 11 hours
Day Temp: 33 Cº (91 Fº)
Night Temp: 22 Cº (72 Fº)

Summer
Day Light: 14 hours
Night Light: 10 hours
Day Temp: 35 Cº (95 Fº)
Night Temp: 23 Cº (73 Fº)

Fall
Day Light: 12 hours
Night Light: 12 hours
Day Temp: 32 Cº (90 Fº)
Night Temp: 21 Cº (70 Fº)


What do you guys think?
