The smallest filter i could find has a 10cm flange and is 20cm tall. It's way too big for my little 40cm x 40cm x 120 cm tent. I tried mounting it on the outside but that proved difficult. Does anyone know if I can use something smaller, like maybe the size of a beer can and where I can get one ? My plants are in week 3 of flowe r and starting to smell
Thanks
