Geckos are fascinating pets, but they require a specific environment to thrive. One essential aspect of their habitat is humidity, which can be maintained through a misting system. Commercial misting systems can be expensive, but with a little bit of effort and creativity, you can build your own misting system for your gecko pet. Here's how Sam does it.

PVC pipes and fittings (1/2 inch or 3/4 inch)
Mist nozzles
Tubing (1/4 inch)
Hose clamps
Timer (optional)
Electrical tape
Scissors
Drill

Instructions:
Plan your misting system: Decide on the location and size of your misting system. Make sure to measure the enclosure and determine how many misting nozzles you'll need. You'll also need to decide where to place the water pump and how to connect the PVC pipes and fittings.
Assemble the PVC pipes and fittings: Cut the PVC pipes to the desired length and use the fittings to assemble them into a frame. Use electrical tape to secure the joints.
Install the mist nozzles: Drill holes into the PVC pipes where you want to place the mist nozzles. Insert the mist nozzles into the holes and secure them with hose clamps.
Connect the water pump: Attach the water pump to the PVC frame using silicone sealant. Use tubing to connect the water pump to the mist nozzles. Secure the tubing with hose clamps.
Test the misting system: Fill the water reservoir and turn on the water pump. Check for leaks and make sure the mist nozzles are working correctly.
Optional: Install a timer: If you want to automate the misting system, you can install a timer. Connect the timer to the water pump and set the desired misting schedule.
Maintain the misting system: Regularly clean and maintain the misting system to prevent clogs and bacteria growth. Replace the water in the reservoir regularly.
Nozzle and Pump:
For a DIY misting system for a gecko terrarium, I would suggest using misting nozzles that produce a very fine, gentle mist. Some good options include:
• Fogger nozzles - These are very fine mist nozzles that produce a fog-like spray. They typically have flow rates of 0.5-2 liters/minute at standard pressures. These would work well for a small terrarium without making it too wet.
• Misting line and stakes - These consist of small misting nozzles (0.5-2 GPH) attached to thin tubing that you can run inside the terrarium and position as needed. You can adjust the number of nozzles to control the amount of mist. This is a very customizable option.
• Low-flow spray jets or misting emitters - These types of irrigation nozzles produce a very gentle spray instead of a direct jet. They have flow rates of around 0.5-5 GPH. You would install them on some tubing or pipe to run inside the terrarium.
• Ultrasonic misters - These high-tech misters use ultrasonic vibrations to produce a cool, humid mist. They are adjustable and can generate a very fine mist. However, they tend to be more expensive, as much as $50-$100 or more for a small terrarium unit.
In all cases, choose a pump that can generate adequate but not too high pressure, around 20-40 PSI for a small terrarium application. You want enough pressure to produce a fine mist but not too powerful of a spray. It may take some adjusting of nozzle types and pressures to get the right amount of misting for your gecko terrarium. The key is keeping humidity high while avoiding excess moisture on the floor of the habitat.
With an appropriate nozzle and pump choice, a DIY misting system can work great for a gecko or other reptile terrarium. But be sure to check on your gecko often at first to ensure the amount of misting is correct and the habitat conditions remain healthy.
Alternative: Spray Bottle
A motorized spray bottle is simply the easiest and most affordable way to add humidity to your terrarium. A typical spray bottle works by using a manual pump mechanism to pressurize the liquid inside the bottle and force it out through a nozzle. The basic steps for how it works are:
1. A tube connects the pump at the top of the spray bottle to the liquid in the bottom of the bottle. When the pump is at rest, the tube is full of liquid.
2. When you activate the pump, typically by pushing down or squeezing a trigger, it creates pressure that pushes down on the liquid in the tube. This pressure is transmitted throughout the liquid in the tube and the bottle.
3. At the nozzle end of the tube, this increased pressure forces the liquid out at high speed. The narrow nozzle also helps accelerate the liquid, creating a spray.
4. A check valve in the pump allows the liquid to flow in only one direction - out of the nozzle. So each time you activate the pump, it builds up more pressure and sprays more liquid.
5. When you release the pump, it creates suction that draws more liquid up the dip tube to refill the system. A small amount of pressure usually remains to prevent the liquid from dribbling out of the nozzle.
6. The pump may have a piston, diaphragm or bellows to help create the pumping action. Pistons are most common for spray bottles. Springs typically return the pump to the resting position when released.
7. A vent in the pump system prevents pressure from building up too high, for safety and to allow continuous operation. Excess pressure would prevent the pump from refilling properly.
So in summary, a manual pump is used to build up pressure in the contained liquid which is then forced out through a nozzle due to this pressure, creating a spray. Releasing and re-pumping the pump recharges the system for another spray.
Mechanism of a Motorized Spray Bottle
1. Use a servo arm extension - Attach the servo motor's arm extension to the trigger of the spray bottle. This can easily pull the trigger when the servo activates. You may need to glue, tape or securely fasten the servo arm to the trigger for the best results.
2. Create a linkage - You can construct a simple mechanical linkage between the servo motor and spray bottle trigger using materials like craft sticks, straws or wire. Attach one end of the linkage to the servo arm and the other end to the trigger in a way that when the servo turns, it pulls the linkage and activates the trigger.
3. Use a loop of string or twine - Tie a loop of string to the servo arm and loop the other end around the spray bottle trigger. Secure the string so it firmly pulls the trigger when the servo activates. Make sure not to wrap the string too tightly around the trigger.
4. Fabricate a clamp mechanism - You can create a clamp, clip or grasping mechanism attached to the servo motor that closes down over the trigger when activated and pulls it. Then releases it when the servo deactivates. This takes more complex fabrication but can work well.
5. Create a push mechanism - Rather than pulling the trigger, have the servo motor push down on a lever or rod attached to the trigger to activate it. When the servo lifts, it releases the trigger. This requires mounting the servo above and aimed down at the spray bottle.
6. Use an intermediate lever - Have the servo motor turn an intermediate lever, see-saw or bell crank that in turn pulls a linkage or cable attached to the spray bottle trigger. This gives you more flexibility in how and where you mount the servo motor.
In all cases, you will need to power and control the servo motor, typically with a microcontroller board or relay. Adjust the servo position and timing to get the desired spray duration and frequency for your needs. With some experimentation, a motorized spray bottle mechanism can work great.

Where Gecko Lives
Geckos are found in warm climates throughout the world, including:
• Tropical and subtropical regions of Africa, Asia, Australia, the Americas, and various Pacific islands.
• Deserts and dry grasslands in Africa, Asia, and Australia. Some gecko species inhabit deserts from northern Africa and Asia to India and Pakistan.
• Rainforests, especially in Asia and South America. The tropical rainforests of Southeast Asia and Madagascar are home to many different gecko species.
• Warm coastal areas, islands, and mangroves of the Indian and Pacific Oceans. For example, many geckos inhabit the coastal areas and islands of Hawaii, Polynesia, Fiji, etc.
• Mediterranean regions of Europe, Middle East, and parts of Asia. The Mediterranean house gecko is found throughout southern Europe, Middle East, and India.
• Urban areas in the tropics and subtropics. Some species of geckos have adapted well to living in and around homes, buildings, and even cities. The Tokay gecko is well known for inhabiting homes in Southeast Asia and Indonesia.
So in summary, geckos can be found in a very wide range of warm habitats, including rainforests, deserts, grasslands, coastlines, islands, and urban places within Africa, Asia, Australia, South America, southern Europe, and various oceanic islands. They have adapted to survive in all these diverse environments, in some cases even living right within human settlements and buildings. While most gecko species inhabit tropical regions, some also live in drier and more temperate places. They are truly cosmopolitan lizards.
Fun Facts:
1. Geckos are known for their ability to climb walls and ceilings due to their unique toe pads that can stick to almost any surface.
2. Geckos are found in many different colors and patterns, ranging from bright and bold to subtle and camouflaged.
3. Some species of geckos can make sounds, including chirps, clicks, and barks, which they use to communicate with each other.
4. Geckos can shed their tails as a defense mechanism when threatened by a predator. The tail will continue to wiggle, distracting the predator while the gecko makes its escape.
5. Some species of geckos are able to change colors in response to their environment, such as blending in with the color of the surrounding terrain.
6. Geckos have excellent eyesight and are able to see in low light conditions, thanks to their large pupils and specialized eye muscles.
7. Some species of geckos are kept as pets and are popular for their unique appearance and ease of care.
8. The smallest species of gecko, the dwarf gecko, can grow to be less than an inch in length, while the largest species, the tokay gecko, can grow up to a foot long.
9. Geckos are found in many different parts of the world, including Africa, Asia, Australia, and the Americas.
10. Some species of geckos are considered sacred in certain cultures, such as the leopard gecko, which is believed to bring good luck in some parts of the world.
