I still use a 40 gallon tank for my BP. I have a rack and some pvc cages but I really like the tanks so I still use two of them.

Getting your humidity up is not hard and you just need to employ one trick I found and have used now for a good while.

You simply add moss to the hides. During a shed I keep the moss moist and do no allow it to dry out. During regular times I make the moss moist and then allow it to dry out before making it moist again. This moist moss will boost the humidity inside the hide so it will benefit your snake the most since the hide is where is spends the most time.

The humidity in the rest of the tank will remain low but that is not important. Using this method I get perfect sheds for my BP and never have to worry about humidity levels in her tank.

Just break off a clump, make it moist, and stick it in the hide. It is truly that easy. It also adds to security by making the hide seem smaller and therefore more secure. This can be very helpful when your snake is between hide sizes and you have to use a hide that is larger than recommended.
