Hi Ci. I thank you for the link. It is quite an interesting thing, haven't thought to link the pots to a gravity feed water tank.

It would have helped a lot today with the watering. So many things seem to have dry pots today, and I was busy all day long. We need a good soaking rain, about 2 inches would work nicely for starters. :)

We've hit our dry, hot season. I have to water most days. I can't imagine watering 500 pots. It has to be a huge job.

I bookmarked that site, cilantro. Thanks for sharing.
