I believe like Subcool that you should plant the seedling in the same pot you are going to flower in. I dont like transplanting it causes stress on the plants therefore I think imo that its best to just let them grow in the 16 oz cup throughout its whole life.I don't mean it as something to do for a normal grow, I just wanted to point out that these guys might have been able to do even better if they didn't have to use a 16oz cup the whole time, just have 16oz be the final pot.
