Help with the homemade humidifer on this site?

All sounds about right to me. I have no background in hygromics or thermodynamics (if anyoen does pls chip in here) but I imagine there would be a limit on how big a container you could utilize without the moistened air getting re-absorbed before getting pumped out. That would likely be tied to the amount of air space at the top of the bottle. Again that's just a troubleshooting shot in the dark. I am assuming you have a covered lid/top for the enclosure. The tube lengths sound good - is the tubing fed in on the arm side or cold side? How far down into the enclosure does that tube run? Another factor that would be sure to play a role is the overall ambient room humidity. Maybe any or some of that will help - I've only used the bottles as described in the DIY (though diff sizes of the same) but nothing approaching a gallon size. My first stab at it used a 2L bottle - which also worked fairly well with the exception the lid was painfully small to get both tubes fed in aand sealed right.

how often would you have to put new water in a 2L bottle?

my ambient air temps in the room are 63-67.

I have the tubing sticking about 1" into the cage from the rear on the hot side. I tried the tubing on the cool side but it was worse, I am assuming warming air holds humidity better so the hot side is the better side for the tubing to be on. The tubing just sticks through one of the air slits on the back of the cage which is towards the top of the cage. The tubing has to sort of be flattened out to get through the skinny air slot but this doesn't seem to affect the airflow coming out of the tubing..

I had to top off the bottles (any given size i had used) about 3-4 days - they werent near empty but i wanted to try and keep the open space at the top of the bottle somewhat consistent.

With the tube in only 1" (near the top yes?) you may be losing the moisture quickly. Warm air does hold more moisture than cool air - but it also rises and if the tube isnt in there very far it likely isnt taking much effort for that to vent right back out. The tube being pinched also might be affecting it - as I know that will create increase pressure at that point and might bleed humidity off as well or at least constrict it (any HVAC folks in the hizzy?) - again all that is based a my shoddy understanding of the science behind it.

How arid is the room all of this is in?

The tubes in your bottle, does the air supply bubble thru the water or just pass above the water?

the room humidity stays between 35-40% during the winter..

the air tube goes all the way to the bottom of the bottle where it connects to a circular air stone and then the air comes out of this air stone and makes bubbles in the bottle..

so what type of bottles where you using and how big were the bottles? what size was the tank that the you had the tube in? towards the bottom or the top of the cage?

ps.. I put the tube through one of the air slats in the back of the cage because I didn't want to drill another hole in the cage for this tube and since I could sort of flatten out the tube to fit through one of these air slots I thought it would not be a problem, as I can still feel air coming out of the tube just fine with it sorta flattened out going through the air slot in the cage...

Weird. Environment I was using it in was even drier than that. I was feeding it into a 10 gal (for a juvie) with a contac paper covered screen lid. I'd used the size gatorade bottle pictured in the DIY section as well as one size smaller - both of those after having tried the 2L. Your enclosure simply DWARFS what I was using. I ikmagine for somethign that size youd need bigger tubing and a higher rated pump to push it. And definitely a gallon resevoir or larger. But with that T1 I'd expect it would hold heat/humidity more efficiently.

My more arid environment might explain why the water was spending faster - then again the humidity in the tank was right where I needed it. The tubing I had ran into the cage to about midway between hot and cold and was close to the floor of the cage.

I think I will have to go with not enough airflow for the size of enclosure you are dealing with.

i would guess, bigger pump to push more air. you want to see a little water in the tube going into your cage. for the price of a pump you could just buy a room humdifier and treat the air around the cage and do the same thing. i.e. if the room is 50-60% the cage in the room will be close to this too.

yeah I can't make the room humid enough because it's in my living room which has all open walls to the rest of my house..

I don't want to push too much of a high air stream into my cage becasue it might give my snake an RI..

I thought that the do it yourself humidifier was made for a cage the size of my T3? I would say my T3 inner dimesnions are about equal to a 40-50 gallon glass aquarium. And the air pump I have is rated for 60 gallons.
