without damage,,,, not gonna happen...a month old..... you should try and pull out the liitle ones and through em away than put your hand over the pot and turn it upside down and let the rootball slide out in your hand, if the roots are really tangled you coyld try submerging the rootball in water and try to gently pull the plants apart while shakin it around alil. prolly will rip some roots but oh well. be prepared to plant em directly after getting em apart and you may be ok, if not start new seeds 1 per pot and you can have that much growth in a few weeks. give em low lighting like cfl lighting not too bright your not trying to grow your trying to get em through shock water em with a light feeding of compost tea or sumthin like that
