your definitely looking top notch just curious how that elf is doing on your odors. I used it last grow and it did NOTHING. I tried slow and fast fans, but it just seemed odor went went right through. This was on 800 watts, 13 plants. and same elf carbon filter, this crop, im venting it through the filter, then right out the window and im using a ozone generator for entire room in small bursts to guarentee air outside room is good.
maybe its the lack of true air tight in hydrohut, but damn if the fan i had didnt suck the walls in so much i dont know how air escaped and odor especially.
