    Default Do I need extraction fan

    Hi guys so got everything sorted out ready for my first grow but was just wondering if I absolutely need a fan or is there a way to get a draw running straight through up to my CF?

    Cheers

    100% need an extraction one. Weather its suckin through the must have filter or blowing through it. Either way yes you need one.

    But intake fan.. now thats a fan you can get away without having dependin on size an setup of grow space
