just hook the tubing to the cannister. if its the same canister im thinkin about after performance slowes down you can take off the canister flip it around and hook it back up. and get about double the use out of it.

to hook it up go from cooltube fan carbon filter and blowing out of carbon filter
texas grass Reviewed by texas grass on . Ventilation am i figureing this right?????? Based on my calculations for room size . i have two cabinets one is 2x4.5x6=54 cu ft the flowering one is 3.5x4x7=98cu ft total of 152 cu ft The air exchange every 3 min would be 152 / 3= 50.6 cfm (50.6 cfm) + (50.6 x 10%) + (50.6 x 20%) + (0) = 65.78 rounded up 66 cfm The 10% part of the equation is used and added because im using a cooltube reflector on light and the 20% was added for the use of a carbon filter added to ventilation for a total of "66 CFM IS THE MINIMUM REQUIRED"to ventilate Rating: 5
