I have started a pepper project for a botany class on the Olympic Peninsula of Washington. I also happen to live in Sequim, which is in the rainshadow of the Olympic Mountains. I have five different species of peppers with 50 sets of seedlings in beginner trays of Miracle Grow pre-fertilized soil, and will be planting half in the ground and half in a Topsy-Turvy pepper planter in the same area of the yard. I was wondering if you have experimented with pepper yield and overall plant health for an upside-down garden vs. a traditional in-ground setup?

Given suitable growing conditions, peppers grown upside down can be just as productive as those planted in the ground.
