Need help with room design

[DaKindbuds]

Is there a site that will hep me with designing my ventilation, I'm stuck on what I need to do

Have you looked under the 'grow room' tab? The first link - 'how to grow marijuana' has some info. Or do searches on ventilation in the forum, or post specific questions and you'll get help for sure.
