Alright. I got home from PetSmart an hour and a half ago. I couldn't find the nano stuff, so I bought a $20 dome with a dimmer. Well... when I got home I found out I had a 40w bulb that would do well in my domes I already had . I put the 40w in there and tested it out, and it worked! I cut out another hole in the tin foil for the other dome and set it on there. (I can get a pic) I left it for an hour or so and here's what my temps are reading now:
Cool 79°F
Warm 82°F
Is this okay? I still haven't opened the dimmer, so I'll return it if this works. If not, I'll open up the dimmer and adjust the temps
