Time: 2 hours
- Two five-gallon food-grade buckets (A)
- Drill with ½-inch hole saw and 1/16-inch bit
- Cloth or nylon strips (B)
- PVC pipe, ¾-to 1-inch wide, 18 inches long (C)
- 16 quarts of soil (D)
- Seedlings or plants (E)
- Trace the mouth of the pipe on the bottom of one bucket, less than an inch from the edge. Drill and sand out that circle.
- Drill five additional 1/2-inch holes: one in the center and four evenly spaced around the edge. For drainage, add eight smaller holes spread around the bottom.
- Tie a knot at one end of each cloth strip. Feed the strips through the 1/2-inch holes so the knots sit on the inside and the cloth hangs down.
- Put the holey bucket into the second one, mark a spot on the outer bucket where the holey base hits, and separate them. Drill a small overflow hole at the mark and restack the buckets.
- Cut one end of the pipe at a 45-degree angle. Push that end through the pipe-size hole in the inner bucket.
- Fill the inner bucket with damp soil and plants, and keep them hydrated by pouring water down the pipe. Stop adding water when the overflow hole starts to leak.
