I looked at the receipt again and the perlite was actually about $13. Still a very reasonable price for 4 cu ft.

I will be making up a couple of the self-watering containers and adding in some of my veggie plants tomorrow. Here is a photo of the constructed buckets. Looks like it is going to work rather nicely. Fingers crossed!!! I decided to use PVC. Right on the PVC it said "Drinking Water", so I am being optimistic and hoping that they no longer put toxins in the PVC. The PVC manufacturer has a website: http://www.charlottepipe.com . It appears to be produced in Florida. I will be checking their website to learn more about the safety of their PVC products.
