I am gathering ideas for an outdoor potting bench. It will have a small roof I think. You may even call it a gardening bench as some activity will include 15 gallon containers. Anyway, if I promise not to paint it in camouflage colors or neon pink can I elicit a few functional suggestions from you about what you like about your setup? Wheels? A insert screen cutout area that can be changed out for different types of compost filtering? Is 8 feet too wide? What about depth?
