Air pots seem to be what a lot of growers use. I use the fabric smart pots and my plants love em. But both seem very similar in what they do.

The other day I had an idea and after testing, it works great.

To know if you need to water, get yourself a soil meter.
Poke or drill 4 holes in your pot 1/4 way up from the bottom spaced around the pot.
Insert the meter probe into the hole and test for moisture. If its dry, then water slowly until it reads on the meter.
Stop when the meter reads the water. It's full.

How do I say this politely.... fucking brilliant brother... thats exactly where you want to know the moisture level.

The only possible exception would be in tall skinny pots but not common to see those at all.

It occurs to me that using the probe makes automated water on the plants demand possible.
One of the members here does electronics with arduinos and stuff. It could be programmed to automatically slow water the plant until the sensor triggers again.
You would never have to worry if the plant needs water or not. It would be automatic.

Trigger points could be customized for the type of grow.

With a sensor grid, you could even determine if one side is hydrophobic by how long it takes for water to reach it, or not reach it.

So, you can add auto-watering right in there with auto logging. We need a great mist head that sits on top. Any 3D printers in here?
(I want one of the first production models. LOL)
