It is amazing how the odor changes. The pk was a little smelly during flower and then a couple weeks into flower was skunky, now it is smells almost fruity sweet and very strong.
So when you say huge, how big is the filter? I am looking at a 42" to hook up to my 6" vortex, my DIY filter I made isn't working anymore.
Hey on another note, I have a buddy that wants to trade some clones. He has some og, puple haze and green crack. I will have to get some opinions on the og when it's done before I decide.
Yeah man, the odor change can be significant. The filter I am using is Can 66.
If its one of original cuts, then there is almost no question about OG's potency, its easily one of the strongest stuff I have had.
I have been observing the OG and HG very closely since the beginning. My opinion about OG is that the number of plants doesn't matter as much as having a screen does for a higher yield. Next run I will begin flowering the OG before it hits the screen, in the first week or two of flowering the the stretched stems with popcorn style bud showing up could be bent in the screen kinda making each popcorn bud a mini main colas, since they will be at the same height after bending in the screen, the light could also be lowered. Oh yes, super crop, fim, and LST before entering the screen.
The HG requires a completely different strategy for a good yield.
I keep waiting for something to go wrong.. Let's hope both of us have amazing first grows. It really is geat how much the folks on this site can help someone who is just starting with no experience.(If they take the approach you have and aren't know it alls) You are setting the bar for beginners Bro! Keep it up.
I am over thinking about overthinking. 
Fuck!! Now I am over thinking about thinking about my over thinking. 
How is the odor?
