I planted these more for testing purposes rather than pepper production. The output is more than satisfactory considering they are growing in only a half day of full sun. This is an east facing exposure.
The small planting area (about 3' x 3') is a powerful demonstration of how city dwellers with limited space can grow fresh produce using affordable sub-irrigated planters.
All we need is better public education. It is woefully lacking at the present time.
You might compare these photos with this set of photos of Public Farm 1 at P.S. 1. It is my professional opinion that this farm would have been far more productive if the planters were sub-irrigated rather than drip irrigated.
