This is a nice teaching image. Thank you.
does it look like they are stretching?
isnt this a waste, how much do you get from each crop?
It was a good effort, but you could never get a decent adult plant with a planter so shallow as this one. The minimum size for a pot that SWIM would use, MINIMUM of a 10inch depth, and even that is on the small side. The planters swiM uses are usually 14-20 inches deep and can vary in diameter. But you get the idea. I would be very suprised to see big, healthy adult plants growng in such a small amount of soil.
