I started doing some dry runs last night and tonight,going well so far.I was not going to use any venting as there is plenty with the air gaps around the door and a few other"oops spots" i have,but i am getting less of a temp gradiant than i want...i may add a small vent on the cool side.
Right now unregulated with two 100W night spot infrared bulbs i am getting 88 at the warm end on the shelf,83 at the cool on the shelf,and 81 on the cool end under the shelf.
I'm thinking with a small vent on the cool side,and 3-75W bulbs instead of 2-100W bulbs i may have a better result.I am getting a good surface temp though,about 120.
