My dayton fan is the middle one rated at 265 cfm. was going to have it not blowing far. It will be pulling about 2 feet or less of tubing, and the 40 cf room.

Lighting is 400w econo-cool switchable ballast. hps and mh.

Hmm... no speed controller :{ mabye I should return it for something else. any suggestions?

p.s. thx for the responses :}
