in my bagseed days, I purposely started 3 seeds in every pot, and when they were a couple inches tall, I'd take scissors, and snip off the less vibrant of the 3 ... I'd then grow out the remaining seedling, and never had any problems, whatsoever ... I did it that way, because I didn't know it was better for them to be in separate pots ... ignorance is bliss :D ... as to splitting them up, (instead of trying to untangle the roots), I have caused less root damage, by simply snipping the root balls apart with clean scissors :wtf: ... if one of your seedlings is significantly healthier than the others, it's an easy decision ... :jointsmile:
