harddon I have read both ways...I have a different take on transplanting than some,
but you are right it could be transplanted in 16oz styrofoam cup and then easily put in bigger pot in 2-3 weeks...so I concede that one to you
RED I think harddon helped answer your question, but yes, you want plenty of room for root growth, but again harddon was right about too much wetness too soon
did that answer your question?
