Ventilation
I'm trying to calculate what size fan and carbon filter would be necessary for a box that was:
4'x4' and 6' tall. It will be 2x2 boards and plywood walls. I plan on one large in-line fan with a carbon filter above the light exhausting and one or two smaller fans down near the plants for intake. I want to keep as much light and smell contained as possible as this is hiding in my closet.
