Given the situation, I'd say you are acting accordingly. Had it been me, there would've been a few more special characters in my post lol. I'll keep my fingers crossed for ya too!

Start with these, I'm looking forward to when I have the space/disposable income for one of Mark's enclosures but it'll be some time as they come...
An easier method would be to purchase a horizontal grow tent off amazon, there are plenty of options when it comes to size and most come with a rod that you can hang the heat/light elements from.
You'll need to provide a bit more details:
Species:
Diet:
Temp Ranges:
Humidity Ranges:
Details about the Enclosure:
If you can attach pictures of the enclosure, that would be helpful as well.
Your best bet would be to check out the Horizontal Grow tents on Amazon but depending how fast your little one grows, I don't know how long it'd be good for.
