Transplant them into something else. How big are they? It's ok if you have to take a little MG soil with them so you don't disturb the roots.
I transplanted mine about 3 weeks old, didnt even shock it. I transplanted to Miracle grow ORGANIC.. If you get Miracle Grow Organic, make sure you get the potting soil. I went back for more, saw a huge bag of it and it ended up being mulch type that were for non containers only.
Not much 2it! Try looking into Fox Farm: Ocean Forest soil or any other of their products... Or Light Warrior. All mg products will eventualy cause stress... (they put alot of slow release in their soil) ... Try a hydro store or nursery... ... Call ahead to save you some time huh? PEACE N POT
