I've just never heard of anyone pushing air threw a carbon filter from the inside out usually it's pulled threw into the filter then out but if it works it works just never seen, at first I was confused I thought you had the filter just sat outside the tent and just trying to filter the entire garage lol then I seen the pic.
Your fan may be more powerful than mine too I'm a tight wad but they work for 30 bucks shipped at least you will know if you have any issues you can just grab some tape and straps and fix it if it happens
I'm growing Sour Livers from Mephisto it's Sour Crack x The Livers they call it prison weed cause it is so stinky not that it matters cause I'm legal but I don't let anyone know.
I thought yours couldn't stink cause mine didn't at that age and I usually don't hear of them stinking till they develop more but I've only tried one strain so could be wrong. Mine did have a smell but I wouldn't say it stunk more of a plant floral smell or something now its stinky socks which is developing into a berry like smell.
