So recently I finally got my BPs tank's humidity turned up, it seems to be going well. But it keeps going back down every 30 mins or so, so I keep having to mist her tank. I tried the tinfoil method and taped tinfoil around the mesh top with a hole for the lamp to shine through. However the Humidity still goes down, and I've taped it as much as I can. My top setup is a little weird. Its a wooden home made one with a little wooden frame on top to clamp lights onto. Taping the foin around the whole was a little bit of a challenge.
