My brother recently built a 20' x 10' greenhouse in a designated area in his yard. We're hoping to build some boxes inside this week/weekend and we're struggling with the layout. We're hoping to grow a variety of onions, carrots, tomatoes, herbs, and some fruits (if possible). I've poked around the internet for layouts to help guide our project, but the solution for us isn't clear to me yet. Should the boxes be in a single U-shape arrangement? Does it make sense to have three isles?
