This project turned out exceptionally well, and I thought it'd be a good one to share. It's a dish garden which will eventually house some Mexican Pinguicula in my office window at work.
- Outer shell of self-watering pot from Wal-Mart ....... $5
- Black plastic kitchen funnel, approximately 2.5" diameter from grocery store ....... $3 for pack of three different sizes
- 25/25/50 peat/sand/perlite media ....... ~$0.50
I cut the funnel to the proper height, then flattened it using some needlenose pliers so that it takes up less surface area. Then, just held it in place and packed media around it until it was firmly in place. The funnel allows you to water the garden without spewing perlite, sand, and peat everywhere. It also allows you to monitor the water reserve level in the bottom of the undrained garden, so you don't drown your plants. The black color makes it pretty unobtrusive. No plants in it yet, and only little leaf pulling sprouts going into it for now. Patience.....
