So IOW. putting multiple plants in a single pot is only a concern if the grower plans on transplanting the plants at some point? So like you say, if that's not the case (and it certainly wasn't what I had in mind with the type of SOG grow set up I've been looking at) then it shouldn't be a problem at all. That's good to know, as it would actually make everything a little simpler in the grow space.
