Think I need some help here.

I'd give it as long as it takes.
Go on the hydrometer and bubbles rather than the number of days.
My beers never take less than 12 days, and I keep the temp between 18 and 21degC.

what he says ^. I ferment at about 19 degrees, sometimes up it to 20 after a week. I too have never had a kit ready in under 12 days, some have taken 3 weeks and they're better for it. As long as you're not messing with it too much it should be fine in the FV.
AG#1 on the other hand seems to be going faster even at 19, whether that's better wort or better yeast I don't know but I'm hoping it'll be done quicker so I can get AG#2 on the go :drink:
