I put together my own self-watering pot for my container vegetable garden for under $10 for materials! (Does not include cost of soil and plant) Red tub $7.50 (Costco)
Laundry basket $1.59 Source: Goodwill Outlet – everything is sold by the pound!
Watering tube $0.25 Source: SCRAP www.scrapaction.org Tube was formerly a large thread spool
Cotton wicking $0.25 Source: SCRAP www.scrapaction.org Officially a sewing notion, but works great in this application
Tools needed: Electric Drill w/large drill bit (I used 1/4 inch) Scissors eXacto knife
Took me longer to round up the supplies than it did to build it.
