I'm not having as much difficulty growing as I am having with finding the right materials. I need a solution to the odour problem. I remember seeing a DIY USB powered charcoal air filter used to completely filter cigarette smoke. It looks like a promising solution except I currently live in Austira and I have absolutely no clue where to get the charcoal or activated carbon or whatever. I don't want to spend my money on an entire air filter system just to modify it to be USB powered. I am not too skilled in german and I have absolutely no idea what an activated carbon filter would be called and I am completely clueless as to which store would carry such an item. If someone could point me in the right direction, whether it be a specific store or a type of store, it would be much appreciated.
Almost started, need help with a grow box material
