here are some pic's of mine.
so in the middle you can see a wood grate that i pot on. the soil that spills gets collected in the plastic tub under it. on the right side is the soil bin i mentioned. when i make a new one later this year it will pretty much copy this as it's worked very well for me.

working with my hands is a joy,it gives me a sense of fulfillment,somthing so many seek and so few find.-SAM MALOOF.
