Essentially you are root pruning, just with a clippers. I have my DCOs in the bottom of my shop fridge and they might have 1/4" radicals. Rarely open the fridge so I would guess my fridge stays colder.I hadn't thought of cutting the radical. I would have tried it if I had the knowledge to do it. Thanks for the head's up!
My DCO's a couple of weeks ago. They were kept in the fridge but I couldn't keep them from sending out a radical so I stuck them in pots.
They started top growth almost immediately. I'm afraid that such long radicals before planting will mess them up somehow. I guess we will find out.
