You can do it. A good thermometer/hygrometer is the acurite 00891, you can put the probe on the hot side and the whole unit on the cool side for cool temp and humidity. They are only $12 on amazon and some Walmart carry them.

Keep the uth off until you get something to regulate it. If you can afford it get a spyder robotics Herpstat 1 or a ve-200 from reptile basics. You should also get a lamp dimmer for the heat lamp but you can raise it up if it's to hot until you get one. Once you have a thermostat or something to regulate the uth you may not need the heat lamp unless your cool side is under 78, if it is under 78 you can have the uth for the hot side and move the heat lamp over the cool side and dim it down to around 80. Also only run the night heat bulb 24/7, bps don't need the daytime light bc they can go by the natural light in your room and you will have to flip the dome every day and night so the night time will be heating the same spot as the day time and that will be a pain so it's easier just to run the night time all the time so just take back the day time. I would position the night heat bulb so it is directly over the hide and then when you get the thermostat or something to regulate uth put the uth so its under the hide.
