# Watering Settings # Monitoring and/or Watering Your Plants
The `grow-monitor-and-water.py` example can monitor and, optionally, automatically water all three Grow channels. The `grow-monitor-and-water.py` example can monitor and, optionally, automatically water all three Grow channels.
It's configured using a settings file - `water.yml` - that looks like the following: By default auto-watering is disabled and an alarm will sound every 1s if the `warn_level` is reached.
Run it with `python3 grow-monitor-and-water.py`.
## Monitoring
Grow can monitor the moisture level of your soil, sounding an alarm when it dries out.
Grow is configured using `settings.yml`. Your settings for monitoring only will look something like this:
```yaml
channel1:
warn_level: 0.2
icon: icons/flat-4.png
channel2:
warn_level: 0.2
channel3:
warn_level: 0.2
general:
alarm_enable: True
alarm_interval: 1.0
```
## Watering
If you've got pumps attached to Grow and want to automatically water your plants, you'll need some extra configuration options.
See [Channel Settings](#channel-settings) and [General Settings](#general-settings) for more information on what these do.

- ``cd grow-python``
- ``sudo ./install.sh``
**Note** Raspbian Lite users may first need to install git:
``sudo apt install git``
Or... Install from PyPi and configure manually:
-----------------------------------------------
- Run ``sudo pip install grow``
**Note** this wont perform any of the required configuration changes on
your Pi, you may additionally need to:
- Enable i2c: ``raspi-config nonint do_i2c 0``
- Enable SPI: ``raspi-config nonint do_spi 0``
And install additional dependencies:
::
sudo apt install python-numpy python-smbus python-pil python-setuptools
