And how many plants can fit in it? I bought a black garden mat to go under. It's 3.25 ft long not sure how tall. I believe it's untouched red wood.
Maybe 10 lb bags will it take to fill?
I had a bigger bed in mind but this is a just cheap start to see how things will go.
Don't roots usually grow out instead of down? Can I just plant a clone in the middle, or two next to each other?
