The heat pad or other element is controlled by a thermostat. Place the probe either on the element itself or in the cage. If placed on the element, you will have to set the thermostat some number of degrees higher to get the desired temp in the cage. Monitoring the temps will tell you what exactly to set the thermostat at. Wherever you polace the probe, make certain it is secured in place and can't move or your temps could be affected.
The temp gun and/or thermometer only tell you what the temps are. IMO the temp gun is invaluable for checking temps as you can check temps anywhere in the cage, even the surface temp of the animal itself.
Some will tell you daily spritzing is necessary. I don't spritz any of my cages. I prefer to set them up to maintain humidity without daily intervention. The adults don't require as much humidity. A good damp hide with large surface area water dish and limited ventilation and you should be fine.
>>Yes the wood chips are cypress(just looked at my order awhile back) I have abotu 20 more lbs of it so I think I have plenty. I am going to get everything you suggested on that site except for the temp gun, I have a hydrometer/ themometer and then I have another themometer with a probe. Could you just explain to me how all that works together to keep the heat pad at a certain temp. I found a metal screen heavy duty screen top for my 10 gallon and im going to get the plywood like you said and maybe drill screws through the metal onto the plywood and cut off the remaining screw tips. As for the time being I might as well order some frozen pinkies somewhere from a site, will all these guys accept a frozen pinkie??? What kinda sprayer do yall use for your cages?
