Some day water will be more precious than oil. Having a system of pots being fed from a central reservoir is possibly the most efficient method of watering.

I use "wet pots" that are buried ~15" in the sub-terrain and they certainly do the job in providing sustainable nourishment to the plants.

My system is now in the sixth working year and I have not had a single problem, every now and then I dig one up to evaluate it's performance. Working like a charm!

I keep adding pots ( I must have cast >150 them to date) and the water savings is very, very obvious.

The current cost-of-pot versus cost-of-water is still a mis-match (but every day it gets better and better), but for me that is no reason "not to preserve a precious commodity". Look at it this way casting pots is also fun and challenging.

E-mail me if you want additional information.
