The guy I'm looking at isn't quite that size, but he doesn't really seem to be a baby, either. Here's a picture - I realize there's not much to go by in the picture to judge his scale by, but I'd say he's maybe 2.5 inches. I only want to buy one terrarium, and I feel if I bought the smaller 12x12x18, I'd just regret it further down the line. If he's uncomfortable in an 18", I could house him in a small critter keeper until he grows a little larger.
The Zoo Med version of the hood I'm looking at goes up to 60 watts, but it doesn't have the adjustable dimmer your domes have. It seems like it would be a little more difficult to get the correct temperature in the cage without a dimmer, but if I were to use a UTH in conjunction with the Zoo Med hood, it should be possible, correct? Would there be any issue with adding a cheap plug-in dimmer from Home Depot to allow me to dim the lights in the the hood? I just prefer the look of the hoods a lot more than the domes.
Is there any difference in using the red bulbs over the blue moonlight bulbs if I prefer the color? Both are used for heating, but most people seem to use the red ones from what I've seen on the forum.
