Pretty much. Nothing's sprouted yet, and I did lose a batch to an
over-exuberant dog. I made several improvements, such as a retaining ring
that holds 5 planters together so that no single one can tip over, and a
bracket to hold the electronics above the water level. I'm currently working
on some clips to attach to the sides of the planters to keep the moisture
sensors in place.

There was a script by another user, for one moisture sensor, but then I built
on that and added features that I wanted. The part that I didn't really
think of, but that the other user's project addressed, was to calibrate the
sensors by taking a reading in the air, then a reading in a glass of water,
and converting everything between those two readings into a 0%-100% scale.

I've created a new batch of planters and plan to plant all of the same seeds
in these. I'm waiting on more sensors and seeds; I've decided on Chinese
5-color peppers.
