    Hello,

    I am about to upgrade my grow room and I wanted some opinions regarding venting my new 1000 watt. I know there is lots of questions about this, but I couldn't find anything specific about 3 1000 watts in a line.

    I am going to be upgrading to three 1000 watt lights, and to reduce the number of bends in my duct work I was considering doing the following:

    OPTION 1 (MOST DIRECT DUCTING ROUTE):

    Vent my three 1000 watt HPS (with 8 Inch reflector hoods) in a line, using 8 inch ducting, and two 8" Can Max Fans on each end to compensate for bends in the ducts near the end of the line, and where it begins.

    OPTION 2 (LOTS OF BENDS):

    Vent each 8" reflector independently, but still using 2 8" Can Max Fans, just way more duct work, and wye type connections. However, due to room location/shape there would be several 90 degree bends for each light instead of just 1 if they were in a line, which I'm concerned may be an overall reduction in cooling.


    Which option would provide the best cooling?

    Anyone run 3 1000 watt lights in a line with any problems? (IE. 3rd light getting too much heat).

    Reason I'm going to be using the 2 Max fans is to compensate for loss of CFM due to bends in the ducts.

    Is two max fans overkill for 3000 watts?
