I didn't realize I was starting another tank vs. tub debate!
I've had my BP in this 20L since I got him in Feb. and haven't really had any issues with temp and humidity since the first month or so. I did have to cover the screen with some foil to help hold humidity, but now I've pretty much got it down to a science. I can change the humidity at will with minor tweaks to help facilitate shedding etc. However, in my current situation new snakes aren't really an option, and I prefer to have my one and only snake on display rather than in a tub.
I kept a rescue in a tub for a month or two, and realize the ease of using a tub. Even with this experience I still feel like a glass tank is the best option for me, even though BPs always hide and suck as a display snake.
That is exactly what I meant when I was saying this will be a slow transition so that I can acquire the proper equipment. I will be investing in a quality t-stat and mostly likely some flexwatt. I also need to build/buy bigger hides, and some "decoration" to provide a secure environment in such a large tank.Also Keep in mind you may need to also upgrade what you're using as a heat element. Its going to be a big difference in a 50G maintaining your temps depending on what you're currently using.
Thanks for all the input guys.
