This humidifier could be used mainly for a reptile tank that has "humidity problems". It is inexpensive and easy to build.
To build this "humidifer" you need:
List of supplies:
- Pump (one used for a fish tank would be good)
- 2 Liter Soda Bottle
- Air stone (which is the stone that you attach to the air hose and produces air bubbles)and blade
Cut two lengths of hose. One for cap to tank, one for pump to bottle. Drill hose sized holes into one cap and one into the side of the bottle, about 5 inches from the top.
Insert tank hose into cap, then silicone for airtight seal. Insert pump hose into side, feed through top, install air stone, feed back down to bottom. Silicone around side hole.
When silicone is dry, fill about half way with water.
Finished product. Put the reservoir someplace hidden, feed the hose from cap down into tank and place where desired, turn on pump.
For increased "humidity", use smaller bottle or raise water level. A larger hose to the tank, or more than one hose works as well.
A three quarter bottle keeps the tank I have at 50-60 percent.
For more humidity, put a sponge inside the "reservoir". It will cause more humidity to build up inside, instead of the air escaping out of the hose without being properly saturated.
