it does make sense.... and is valid... i guess i wasnt clear enough about the checking for root bind
obviously, even if things are root bound if the plants are in the last week of their grow it just doesnt matter much either... in fact, it could be attributed to a very efficient grow style at that point... using all that is available with no waste
the thing is though, the bigger and healthier the root ball the bigger and healthier the buds are.... so, personally, i would rather use pots that are too big than too small.
