Vertical Grow Wall

My Grow Up wall is a great way of getting early and late production out of my greenhouse. It sits on the north side of the greenhouse, facing south, so it gives me an extra 1.5 beds worth of crop in an area that would otherwise not be growing anything. This kind of simple low tech is great for urban farms who face a lack of space but would still like to find ways to add more production. We have found basil or cut and come again crops to be the best things to grow in here. Head lettuce would also work well.
