Because pollution is everywhere, this is the NASA Guide To Air-Filtering Houseplants. Was it actually made by NASA? I'm not sure. Maybe it was just made by somebody pretending to be NASA. I've pretended to be from NASA to impress people before. Remember: just because somebody has a fire burning under their ass doesn't mean they're going to space. Also, is black mold good to have in your apartment? Because I'm growing tons of that, I don't even have to try it's just everywhere.

Thanks to Julian, who takes all his plant-related queries straight to Poison Ivy.
