Okay so have a 32 quart sterilite tub. Its not very tall but not way shallow. (23½" Length, 16" Width, 6⅞ Height) (Or 60.3cm x 40.6cm x 17.5cm). I have 10 holes drilled on the long sides for airflow. I use a mix of plantation soil and coco husk. Since the tub is pretty big for a hatching, I have several hides and plants for cover. The only issue is that the ambient temp is too low. I have a UTH set to 91°F that covers about 1/3 of the tub. I have an infrared temp gun and I when I check the temperature it usually reads between 69-74 which is really scaring me. I got a second thermostat and UTH in an attempt to raise the temperature but it really didn't do a whole lot. Please help!
