So I am building my grow cabinet now. The dimensions are 30" X 20" X 72". I have a vent I will be putting on the bottom of my cabinet. I hope to vent through the top section of cabinet and connect my vent fan to a carbon filter I will make myself.
What's a good economy vent fan? How many CFM do I need? Does Walmart or Target sell a model that would work? Can I hook a square bathroom fan up to a carbon filter? (My plan was to use a circular one and attach it to ducting, but at Home Depot the only circular bathroom fan the size I want is a lot more than I want to spend.)
I'll be using a 250 Watt MH with no air cooling so I need this to keep my cabinet cool and also to provide fresh air.
