yeah, weather seals, water seals, like around the edges of your car doors, you can use rubber cement or cocking to attach them to the doors. There are even door seals, but I have noticed they leak light a bit..... check at a window/glass store, or a home depot or something... you should find seals to your liking. If your going to grow in there, I highly recommend creating an exhaust system by cutting into the wall (that is if your don't want light to escape) and putting a fan with a filter attached to stop light and smell.... good luck, hope it was informative... as I hate it when people try to answer my questions and I am still in the dark.... but my problem is more that people just don't really answer the questions I post....
