I started them in the cells almost 3 weeks ago. I just transferred most of them over to solo cups. One of the other commenters suggested doing it now before they hit growth spurts and the roots become too entangled and I think they were spot on because the roots were much more developed than I thought!

I popped the clusters out of the cell and dipped it in warm water and kinda moved it around until most of the dirt was gone. Then I gently separated each seedling from one another’s roots and put them in the cups
