very nice.
when mine get that big i drop them all the way into the bottom of a beer cup. only put enough soil in it to reach the leaves. as the seedling continues to grow you can add more soil. keep your light low. by the time it reaches the top of the cup it should have a couple sets of leaves and a nice sturdy stalk.
The only reason I haven't transplanted yet is because I want to slightly stunt the larger ones that germinated first. That way the slower seedlings will catch up a bit.
A small difference in size now can be exaggerated later on. That might mess up my ScroG.
Tomorrow they all get small containers with Fox Farm Happy Frog.
14 of 15 are developing true leaves (first set). 1 of 15 has a large tap root but is refusing to shoot up cotyledons for some reason. If I see no green by transplant time tomorrow it might be the first victim in the search for good phenotypes.
