So far I think square is winning. Again this is the exact same soil. I think this is a far comparison myself. I will continue to keep doing these types of yield comparisons. I hope you enjoy. The thing is the square container seems to add some sort of larger intermodal spacing. I can't say for certain, but I think roots like 90 degree angles....... hope you enjoy & check back next week to see just who's faster. & remember its 4:20 somewhere!!!!!!
