the tent is 4x4x6.5. since i'm only doing 3 plants a time i wanted a smaller tent but it was all they had. if i just need the one fan than thats awsome! less i gotta spend

how exactly do you set up the carbon filter? does it hang at the top inside the tent and connect from the left 6" hole of the tent to ducting which connects to the air hood then more ducting and to the right side where the fan will be? so basically everything going straight across then just a flap open at the bottem for air intake?
cypher420 Reviewed by cypher420 on . Can I vent this? Hey so this is my first grow and i wanted to buy this Grow Tent and 400w HPS kit but i'm not quite sure how to set up the ventilation. is it ok if i just set up small cfm fans without ducting? i don't want heat to be an issue, but at the same time i want to keep it as cheap and simple as possible since the tent and light were pricey enough :) any help or tips appreciated! cheers Rating: 5
