minutes??? perhaps you meant to type hours?
Roadkill said:Laura, wasn't being testy, just stressing that the change is indeed in minutes. And like you, yes, I'm too lazy to go change the photoperiod by hand by 2 minutes a day. That's why I dropped several hundred on a controller with computer interface so that I could program the changes I wanted and let it do all the work. Technology is grand.
Roadkill said:Skeetzy, I utilize several for different reasons, you've kind of hit on one issue that I have. For controlling temperatures and a few other things I've got these:

They're a bit pricey, but what I like about them is that their electrical outlets are rated for 450W each and while I can set a monthly temperature regime, by engaging one specific function it will transition from one regime to the next in a gradual manner and over a time period that I can assign. These can control more than one enclosure, but for my purposes I use it for controlling different regions of the enclosure (primarily what I consider subterranean zone and "above ground"). This being said, you can use any controller to control more than one cage via the use of power bars, it's a different thing to control more than one cage independently of others. You can also program these with different monthly photoperiod regimes. But this is where these units disappoint me: while you can have a transitional function for the temperature settings, there isn't a transitional function for photoperiod. This irks me as I feel (and want to research the importance of) that the CHANGING of photoperiod, not the length of photoperiod, is what is important in adjusting their biorhythms and hibernation.
So for photoperiod control I use this:

A rather pricey device that admittedly doesn't allow for independent control of multiple cages, it allows manipulation of photoperiod like nothing else I've seen at all. You can program it for any region on the planet, or you can create your own stylized year to suit your purpose.
