Setting the Appropriate Heating, Lighting, and Humidity For Iguana

Another unique creature that has been a recent fad for pets is the iguana. This seemingly fragile reptile can grow to be a huge one and requires very specific feeding and housing requirement. Proper husbandry should include providing the appropriate heating, lighting, and humidity for a pet iguana.

Data shows that this interesting creature usually grow to as long as 6.6 ft. and can weigh to about 6 kgs. However, there are more recent reports indicating that they can grow to even larger than that, such as the one found in Fiji, which is said to be about 7 ft. and another as long as this marine iguana found a couple of years ago foraging underwater by some divers. They are known to be herbivores, so even if they do grow bigger than the regular-sized iguana, there is really no reason for you to fear. Still, you have to make sure that you have provided your pet with a room or an enclosure big enough to allow it to roam around without restrictions.


It is also worth noting that an iguana lives more than a decade. Online research indicates that these gentle giants can live to varied ages. Some have even live beyond 20 years. So, if you are planning to have one of these unusual creatures, make sure that you are thoroughly educated and quite dedicated so that you can provide the appropriate care that your pet will need.

One of the essential needs of a pet iguana is the right amounts of heat, light, and humidity. The design of the heating/lighting devices that may be appropriate for your pet will also depend on other factors as the size of the enclosure or habitat, the placement of the enclosure, the surrounding room temperatures, etc. There are several options available online and even in local  pet stores. When choosing the right elements for your pet’s housing, consider the following guidelines provided below.


Heat is an essential element that contributes to an iguana’s health. These docile reptiles are cold-blooded, hence would need supplemental heat to digest the food that they consume properly. They also need heat to help regulate their internal body temperatures. Your pet will need to best heat lamp source to warm its body so that all its organs will function well. Heat should not be provided in the same wavelength within the reptile’s enclosure, however. A range of temperatures (also called gradient) should be provided so that the iguana can regulate its body temperature by moving back and forth between cooler and warmer areas of the enclosure.
