Just opened up my 30 gal smart pots and the rootball from when I transplanted from my 7 gal into the 30 still had circling Roots on the bottom of the root ball,so I'm assuming I didn't get all the growth I could've ..i was told to scratch the roots on transplant to promote root growth and stop the roots from circling and redirecting them in a new direction to branch out.i just want to know if that's true, and what else could I do to help this..are my 30 gal pit really necessary ? I mean they had a shitload of roots but mostly small and not a crazy amount
