re: Gardening - Anyone grow any interesting peppers?

Are you referring to the grid? There's a rough guide of what you can grow in a single square foot. I've replaced the grid in that image with rows of pvc irrigation that help me divide up everything.

When I built the box, I put in a layer of landscape fabric. I wrapped that up to the top edge on the inside and stapled it into place. The only weed issues I get is grass growing up right along the side.

Since the boxes are raised, they drain out perfectly. I've never had any issue with them holding water, even in heavy rains.

There is certainly some expense up front setting the beds up, but year after year it's so easy to grow and maintain.
