6.5 gallon better bottle as a secondary?

[jrodder]

So I have a couple of 6.5 gallon fermenting buckets that I might need to put into a secondary. (Zombie Dust at 7 days ready for dryhop, Graham Cracker ale at 14 days, debating on seconday mainly because of worries about flavor sitting on graham crackers)

I know the headspace is an issue, I considered filling them with co2 before the racking. Will that co2 just get absorbed eventually into the wort without any additional pressure? Or will it sit nicely like a blanket of oxygen barrier until I keg?

It should blanket fine.....should not absorb because the CO2 in the beer is at atmospheric pressure....and the CO2 that you put in the Carboy will be at atmospheric pressure....so everything is nice and equal and happy.
