Alright, these are two very new flasks--just back from the lab. Of course the auger gets a bit jostled during shipment. So here is the question, are these two flasks okay to "bake" a little longer? The seedlings are still pretty small, so I'd like to let them get a little closer to pushing off the cork before I deflask them. But, I'd love your thoughts.

And I know the big seedlings would do just fine, but there are lots of little guys that I'd like to give a better chance to. Thanks for your thoughts.
Sadie it depends on how the flask is sealed. If it is sealed with cotton wool which allows gas exchange, then there is no problem with leaving them in, but if it is cork or some other material that doesnt allow air exchange, then it will be better if you deflask them. Also it will be nice if you replate the small ones in a separate flask where they do not have to compete with the stronger ones for nutrients.
Sarah, I am not an expert and my experience is only 7 flasks but I think you are ready to deflask them. Depending on what they are they may never grow to the top. I was holding one flask since april thinking that it wasn't ready and it didn't got any bigger. I deflasked it about a week ago and the plants are great, just not that tall. I am also giving a chance to every single one in the bath- not throwing away anithing green -and most of them made it so far. Also the agar may damage them- it burns the leaves...
I vote for deflasking!
Those plants look bigger than the ones I unflasked a couple weeks ago and I tried to plant everything green, even seedlings only a half inch tall! I always wonder if the tiny seedlings will have different flower color or something.
