kronos416 Reviewed by kronos416 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
