Rido, your babies look amazing! I hope they are still thriving. I am trying my hand at growing JM bloodgoods from seeds for the first time. I harvested, removed the wings and stored them dry late last fall. I just soaked and put the seeds in damp peat to refrigerate for 100 days before planting in May. I think I will use pots as you did. Here in the Willamette Valley these trees flourish so I can only hope that they come out something like yours. They are destined for a woodland area with dappled sunlight on my property. Fingers crossed!
