Creating Air Circulation

[smweaver]

You could also aim a standard oscillating fan away from the orchids. It will still circulate air by pulling it from them rather than blowing it towards them (perhaps creating less chances of any kind of dessicating effect while still moving the air about). I have three of the twelve-inch size oscillating fans going throughout the different areas of the house where I have orchids. They run twenty-four hours a day, and on low speed I don't think they really spike the monthly utility bill all that much. As far as airconditioning goes, I've found from experience that bringing a flowering plant inside to enjoy the flowers (rather than, say, allowing our thriving population of Japanese Beetles to enjoy them) in the middle of summer while the air's on won't harm the plants (assuming they're not sitting directly in the path of the stream of conditioned air). After they're done flowering, just sit them back outdoors to enjoy their summer vacation (if that's an option for you).

Are you going to have the fans circulatet the air inside the tank, or exchange the air inside the tank with the air outside the tank? If so, you can have air blowing out of the tank rather than dry air into the tank.

For fans exchanging air rather than just circulating it, it doesn't seem like it would matter whether the fan is pointing in or out of the tank. Unless you have a fan powerful enough to create a vacuum in the tank, all the humid air that is blown out by an outward pointing fan will be displaced by dry air that is pulled in through other gaps or openings.

Perhaps you are right, but I just feel better doing it one way versus the other. It seems to me that it would dry out more if I pointed the fan in so it would blow drier air in. Its most likely just a prejudice of mine though

I've got a Rona nearby, so I'll check out those clamp fans...I wonder if they only clamp? or can they sit on their own as well?

Yes indeed, these are also base fans, ya sit them anywhere you want them
