I have it set up as a square on the inside. In doing that you have to put 2 on each end and 1 on each side. 6 total blocks per level. I'll try to take a picture of it later today.

I would love to see it!

Here you go! I alternated the bricks for stability, I also want to point out that I did this on top of patio bricks to prevent anything from digging from below. I do have chipmunks that like to dig in there but I use a live trap and relocate them so they won't damage my plants.

Oh nice. Thanks for the pictures to help me visualize how this is working for you!

Hopefully you get a good harvest, make sure you make a harvest video and post it here then I can come back and let you know just how well I did! Thanks!

I will!
