I have been experimenting with different temps and daylight times over the years every time winter comes around. I live in New Hampshire, so it gets quite cold as you can imagine. Consequently, Luke (my ig), is totally dependant on heat lamps in the wintertime. I have tried increasing temperature and decreasing daylight by different intervals, but have not found the right combonation as of yet. One winter it was too cold, and the next Luke never came out of his breeding cycle. So far this year, I have decreased the daylight to 10 hrs. and have kept the temp ~85 degrees (~95 basking). He seems to be entering his breeding season again, but I was wondering if it is harmful, or even possible, to prevent iguanas from entering their breeding cycle by keeping temperatures and day/night cycles consistant year-round. If not, I would like to get some of your reccomendations on temps and day/night cycles. Thanks in advance!

I don´t think it´s possible to make your ig not go through his breeding season.. You might try to make it last less than it is supposed to, but I really don´t know how.
Now, about the temperatures, I keep the basking place at 95 F, the overall is about 85 F, and the cool place is about 75 F. I think they do pretty good at this temperatures. I´ve never had any problem. As long as you provide the UVb light and the temperatures I told you, you shouldn´t have problems.
In winter time, I keep their lights on for 10 hours, just like you do. Right now it is summer time down here in Brazil, so the lights stay on for 14 hours.
Well, hope it helps.
Later,
Dan
ps: great looking ig!!
