Good morning everyone.

I recently bought another big tank for orchids. Since I grow indoors under lights, this is the best way that I have found to keep them especially with most of them being mounted.

This is the biggest tank that I have so far; about 67 gallons. I usually go with Exo-Terra vivariums because I also keep reptiles and amphibians, but this time I went with the new National Geographic reptile sanctuary which was only about $30 more. Unlike the other tanks, this one I had to put together myself which took no time at all.

I do have a few questions that I'm hoping you all can answer.

First, I bought a humidifier especially for the tank to keep humidity up and to help with the watering of plants in the tank. It's a pretty small humidifier, but it fills the tank up with fog in about 5 minutes and I'm wondering if there is a good way to have it externally (outside of the tank) so that the condensation doesn't cause a short in the fuse since it is a plug in humidifier. I was thinking of using a L shape steel pipe in order to guide the fog into the tank from the humidifier, but I'm worried about condensation on the inside of the tube falling either into the tank which isn't that big of a deal, or falling back into the humidifier possibly causing a mess. Also, the humidifier puts out quite a bit of fog and I want to figure out a way to possibly diffuse or slow the output of fog since the tank was completely full of white fog in a matter of minutes.

Another question that I have is how to go about air circulation in the tank to keep the mist moving and properly ventilate the tank. I took the mesh covering off on the top to help keep humidity in, however there is a side vent that is fairly big that I'd like to have the air move out of the tank through. Does anyone know where I can purchase 3 or 4 inch box fans that plug into the wall or a surge protector? I'd rather go and purchase them in a store rather than order them online so that if they don't work the way I want them to I can easily return them.

I will try to take some pictures of the tank this afternoon so that you can see what I'm working with.

Thanks in advance
Chris

I use a USB powered fan with a flexible a 8" pigtail that plugs into the 120v USB power supply (the one that comes with some cell phones as the charger power supply). It has been running continuously for about 8 months. It keeps the air moving around the orchids and the total cost is under $15.
