Controlling Humidity & Venting

Ok so im trying to find the best way to vent my grow rooms. I have one veg room aprox 8x7x6.5 and a flowering room aprox 10.5x8.5x6.5. Both in a humid Michigan basement. Any one ever used these Duostats? ->http://www.amazon.com/Ventamatic-XXDUOSTAT-Adjustable-Thermostat-Ventilators/dp/B00336G1ME/ref=sr_1_1?ie=UTF8&qid=1298323872&sr=8-1

I ordered one 6" inline fan(530) and one 8" inline fan(675cfm). I was thinking of hooking the fan to a speed controller like this-->http://www.amazon.com/Fan-Speed-Control-by-C-A-P/dp/B004CT3M0K then to the duostat. What do you think?

Also i have 1 1000watt MH in the veg room and 2 600 watt HPS in air cooled hoods in the flowering room. Everything is aero.

So what do you think is the best way to ventilate it? Any input on those Duostats?

What kind of dehumidifier do you have? Your not going to be able to control the humidity simply by venting.

I have one, i was just trying to figure out the best way to vent the room with the equipment i havst now am finishing up my flowering room and waiting on my fans and carbon to build a filter.

i would intake passively into veg through flowering and exhaust out from there. both fans used exhaust is better than using intake fan. and you're waaaay underlit for flower space. 2 600s can flower 8x4 max 50000lumen/sq.ft is the minimum
