hey guys im in the process of building my grow room and was wondering what is the best way to filter air that is coming from out side that is going into my grow room? I want to make sure that no pollen, no bugs, and any fungus or bacteria will get to my plants. any help would be great
Yeah I would rig up a filter from a central AC unit in the wall I would be pulling from like a dryer exhaust port or the openings along the ground in garages.
they sell intake filters they look like car air filters. they just pop on your inlet ducting.. probably expensive.. throw some panty-hoe's over it thatll stop major debree
