Ok so this is for all my friendly tokers and growers that cant afford one of those big huge and expensive activated carbon filters so the things you need to buy are. 1. panty hose ( buy from your local dollar store buy 2 pairs because your going to need 3 pieces try and buy the panty hose socks things or seperate leggings that are pantyhose!) 2. activated carbon ( found at walmart for 3.97 for 440mL/4oz in the pet section , also at any pet store in the fish section) 3.Duct tape (found at any store) 4. 3" and a 4" net pots ( found at any hydro/aero store, if you cant find any go to the dollar store and look for 2 metal pencil cups/holders and make sure there mesh and that they fit inside each other.) ill post pics as soon as i upload them
