So, I’m really thinking of switching to a tub. Reason being is because I can’t bring the humidity up to where it needs to be. It has dropped down into the 40s. But I’ve heard if the temp of my room is below 75, a tub won’t work out too well. Is that true?

I’m using cypress mulch, have sphagnum moss sitting in bowls of water, also inside her hides, screen is covered in foil tape except where CHE is and water bowl is sitting under CHE. What more can I do?
