I've had a terrarium that has been successfully growing drosera and a couple of vft's for many months now. Everything I've read suggests providing some sort of air circulation for the tank, but none really mention how to provide this in a sealed terrarium (other then mentioning the use of a computer fan). I live in Albuquerque, NM where there is virtually NO humidity. Because of this, I keep the terrarium sealed almost always in order to keep humidity up, and although I've had great success growing my cp's, it seems having a fan or some sort of circulation would improve plant growth. So, here's my current setup and my questions:
10 gal. terrarium
3 18" fluorescent lights on roughly a 15 hour cycle
2 drosera capensis
2 standard VFT's
1 Nepenthes Tobaica
The top is completely sealed with glass panes.
1. I'm considering putting a fogger in the terrarium and running it on a 15 minute cycle hourly. Would this circulate the air in the terrarium enough to be of any benefit?
2. How does one utilize a computer fan in a terrarium? Do most people have the fan INSIDE the terrarium blowing in timed cycles? Or do they simply place the fan on top of the terrarium to blow across lights (this wouldn't do anything for air ciculation inside terrarium)
I'm good with wiring and electronics, so I know how to set everything up, I just don't know how the heck to get any kind of air circulation in my terrarium.
Thanks so much for any help.
p.s. I've read a ton of stuff off this board and have learned so much, I'm glad to be a part of this community.
