I'm very close to purchasing a new, gorgeous juvenile BP. The last thing on my list before picking the little guy up is perfecting the temperatures in the aquarium.

I previously used this tank for a milksnake which required lower temperatures, for which a large heating pad on the underside of half of the tank would suffice. However, for my BP I'm going to need to raise the temperature on the warm side about 10 to 12 degrees.

I layered the netting of the lid with duct tape and and tin foil as the tutorial showed, but those temps. are just not reaching what they need to be! (I live in Seattle, and our winter this year is chilly.)

What is one more step I can take to heat this puppy up? (Purchase/homemade/whatever)

Thanks!
