Yeah, by the time I get my NALS seeds I'm tired of starting seeds so they just go into the freezer until the next year (or longer).
I think most if not all of my seedlings will just go into larger pots until fall 2013. By then maybe a few more seedlings will voluntarily cull them selves; that would help reduce the number. I don't have the garden room now and will have to cull a lot of what is out there too. Using the baggie method I can cut away the plastic and gently work them into gallon containers. Might have to split to two containers with those "overly successful" germinations.
Since I am in zone 8, I really can't answer about transferring them outside the first year. I know a lot of people here are in lower zones than me so hopefully they will chime in.
