Hi, My 4 blueberry plant will be flowering soon, they are located in a small room next to my Hvac/Oil Furnace. I just bought a 750Watt HPS Lumatek with a cool tube... I was thinking about hooking the cool tube exhaust to one of the hvac air input duct and replacing the furnace filter with carbon activated one... (http://www.danforthfilters.com.s11.incloak.com/secure/store/wpbec_viewItem.asp?idProduct=9884) The cool tube fan will be the only fan in the room. Do you think this 240cfm duct booster will suffice?
