Having trouble keeping it humid and hot.

Thank you everyone for the advice! I'm going over my enclosure to check for air spots. My phones been acting crazy so I haven't been able to.tske a new picture but here is one picture with just one side of the Plexiglas cut with the heat lamp.

Make sure the foil ring around the base of the dome extends under the dome, too. I like to use the 8" and 10" domes because my domes overlap the foil ring by 1" at least. Then I seal the entire rim of the dome to the foil.
Because my domes are large and my bulbs are lower wattages I also cover up the holes around the light socket. I've done it this way with 4 fixtures for over a year and no problems yet. I wouldn't cover the holes if you have a small dome or use a high wattage CHE for a 12 hour night cycle.
Just thoughts for you to consider.
