My two cents: buy a proper snake enclosure. When bringing an animal home that means taking on the responsibility of housing it as it grows. A proper enclosure should be factored in when purchasing an animal.
You can spend $200 on a grow tent and experiment, then what happens if it fails?? Now you're out $200 and still don't have a proper enclosure. Now you've got a snake with no enclosure while you what? Wait for one to be shipped??
Just spend the money once and be done. You'll have this enclosure for 20 years or more, it's worth it. Instead of worrying about all the "ifs" and having to basically frame it with bamboo...just buy an enclosure made for a snake. Easy breezy.
