I don't want to confuse you more, and this is not typical advice for a new grower, but have you considered a 'sealed room'? That is, no exhaust, no intake... you need heat, perfect humidity, plenty of light and co2 for that though, and everything must be dialed in: http://boards.cannabis.com/advanced-...ent-guide.html

Just wanted to throw it out there as an option, and the guide is a good read anyways. This will cost some $$$, but it's probably worth it for the peace of mind and superb growth. :jointsmile:
