I am starting to make plans for a 4'x2'x2' wooden enclosure for my BRB. I want it to be solid walls with holes for ventilation, so no screen tops. With no screen top I need to heat the enclosure from underneath as I don't want lights inside the tank. I can't just slap a UTH on it so whats the best way to do it? I was thinking about cutting out the bottom on one side and siliconing tile there and placing a UTH pad underneath the tiles. Thoughts? This will be my first build so any and all help would be awesome!
