Elevating Temperature in UV Chamber

I’ve been using the Tough Resin and post curing the prints in the “Nail Salon” set up using the tin foil inserted into the cardboard box set up as shown in the video on the FL site. In reading the guide for post curing the Tough, it suggests 45 degrees C (113 degrees F)… I’m reading about 90 degrees F in my UV set up using the 4 UV bulbs from the nail salon set up. Anyone do any experimenting with elevating the temperature by adding some sort of heating apparatus to increase the temperature?

Thanks for any suggestions.
