After they popped from their seeds I put them right into their forever pots because I read you're not supposed to transfer them, because the stress could be too much. So my idea was that I would plant them in 3 gal pots and use mason jars as glass domes/mini greenhouses. It worked for all of my plants except for 1 but that was because i didn't remove the seed casing quick enough and it never progressed past that stage, the managed to grow the other 5 to harvest though!
