Ideas On How To Get My Closet Light/smell Proof. Help Please :)

[BigBun]

Anyone having some ideas on how to get my closet doors light/smell proof? I dont have a clue because of the hinges and the slackness at the edge between door and closet where the hinges are. I cant use the closet itself and making a frame inside is next to impossible for a noob like me because of the 6 hinges.

Im out of ideas....

Set another closet/cab up the same way. As long as the fan is blowing through the filter on top its causing negative pressure and you wont even have to worry about the doors... you will need a 4-6 inch blower and a carbon filter. There are many cheap combos on amazon.
