Well honestly i would love to keep growing 5' plants in my closet .But i just had all the hardwood floors in my house refinished .And i dont feel like screwing up the finish .But i finally figured a way for ventalation.I place 1 pc fan in the side of the box at the top to suck out all the hot air at top .(since heat rises )And another pc fan towards the middle to lower bottom to blow fresh air into the box.So does this sound like its gonna work? And also all the fan holes will be cut out the left side of the box
