Im going to be building and 8' x 3' x 2' Vivarium and going to be connecting upVicks Paediatric Mini Ultra Sonic Humidifier to regulate the humidity. Im going to be getting a thermostat and humidistat. Which is the best one to get as Ill be looking to create 85f to 90f at the hot end of the vivarium and 75f to 80f at the cooler end. Is it best to have two heat lamps one in the hot end and the other in the middle and then two thermostats one at the hot end and one at the coller end connected to the middle heat lamp? Then get one of them with humidistat and have the pipework coming in at the middle of the vivarium?
