Those look really good! I thought you said you didn't know what you were doing lol. Just my two cents, it takes way more time and resources to get a plant from seed to the point those smaller ones are at now than it does to let them keep growing to twice the size they are now. I would take advantage of all the space you have since they are already growing and thriving. Then again, I don't exactly know how you would keep them in veg and what kind of inconvenience that would be. Just something to think about.
