but they're 405W drawing 245W) I was really happy with the results. Two ladies in a SCROG in a 2.5 x 2.5 cabinet that yielded about 100g each -- and that was with some growing mistakes!
BTW Willy, I read about your uncertainly in LED during your flower. How are they doing now? During my last grow with these LEDs (can't mention the brand here

There are "natural" hermies, but most common reason is due to stress. If you had a hermie, you should double-check to make sure you have NO light leaks in your tent/cabinet! Also, check temps and other environmentals.
Assuming you have good enough exhaust (which I HIGHLY recommend!), you don't need an intake fan, at all. Just use the carbon filter for the exhaust and have intake ventillation. The goal (to eliminate odor) is to create "negative pressure" in the tent/cabinet forcing all the air through the carbon filter. On my tent, you can see the sides visibly "sucked in".
If your exhaust is good, the intake fan won't do much and, if your intake is stronger than your exhaust, you'll create positive pressure and non-filtered air will be forced out of the cabinet and smell up the room.
Go to that Amazin' online store and look for "GrowBright Double Layer 8 Inch Duct Filter".
It's a cheap/simply cover that fits over your intake:
You can configure the fan/filter to either push or pull air through the filter. Most efficient is pulling, so filter, to fan, to exhaust out of tent would be my recommendation.
