Why'd you put them all in one container, you plan on culling now that they've made it?
If you can see roots, I'd get them all potted separately as soon as you can. Before you have a tangled mess during the attempt to transplant. I've made this mistake.
I'm happy to say that I just had all 18 attempted clones from that Big Bud root extremely well in seven days! Don't know what I'ma do with them though, lol. This year I found these little coco pods(just like Jiffy pellets). I use a rooting hormone powder dip, into pod, then into propigator, and mist every other day. This way I can see the roots coming out of the pods.
Also, been meaning to ask ya about that WW Seed Bank...are all their seeds white label packaged?
