This is a side question based on this thread : I thought UTHs say they are for glass tanks and not to use on plastic. I would gladly accept being wrong....as my rack system is already set up with back heat. UTH would have solved my issue that I posted a couple weeks ago...raised floor/walls not getting direct contact with heat tape.
I hope the UTHs work GREAT for you
I'm picking up a hydrofarm thermostat tomorrow
