My enclosure is custom built but I had to use a RHP and Flexwatt for heating. I have a glass panel on he bottom but the rest of the enclosure is PVC. So I would assume you will need to use Flexwatt for your warm side and RHP for ambientsWorks great for me no matter the temp of the room 65-78 my temps stay a constant 80.1 and 89.9 in my enclosure. Only issue I had was buying a T-stat that would control both heat sources
