Light leaks

I'm growing in my closet and light has been comming through the top, bottom and the side without the hinges of the door. What can I do for this?

You can tape strips of black construction paper along the inside border of the door. Covering them again with strips of foil should help as well. The best way to handle it would probably be to get some quality door insulation that screws to the frame. Whatever you do to block the light, make sure you still have enough airflow.

Weather strip is good for this.
