Well Its so dry here I built a DIY humidifier the one with the bottle and the air stone you see all over the internet, but it sucked so bad It was intended for a much smaller environment.
So I built a real Humidifier intended for a much larger space.
Here is what you will need to build your own Evaporative self regulating Humidifier on the cheap.
First a pet water dish with automatic refill.
A few super thick sponges
A small fan with switch (very quiet one from radio shack)
A tupperware plastic square bowl that is about the same size as the open part of the water dish
4 screws or bolts/nuts
