Different irrigation treatments can be programmed into the system.
Each irrigation treatment is a daily schedule of irrigation events that can be terminated in a variety of ways.
The created treatments are not associated with a specific experiment. The irrigation treatments are a pool of treatments that can be used for any experiment.
To set an Irrigation Event:
- Click the Irrigation Treatments menu item.
- Click +Create New to create a new treatment.
- Set the settings according to the images below.
* Timeout - If the "Close valve by" criterion does not meet, the valve will be closed according to the timeout.
"Close valve by" options:
Time | The valve will close after the defined time (in seconds). |
Weight | The valve will close after the defined weight has been added. |
Previous Day Transpiration | The valve will close after the desired percentage of the previous day's cumulative daily transpiration has been added. Example: Plant 1 transpired 150 g yesterday. |
Previous Day Transpiration of Control Plant | Similar to the previous option, but according to the transpiration of another plant. |
Dehydration Rate | Set a daily dehydration rate - daily water loss from the pot. Irrigation will add up water until the defined dehydration rate has been met. Example: Plant 1 transpired 150 g yesterday. If defined 100 g/day, plant 1 will receive 50 g of water. |
By Sensor | The valve will close after the sensor reaches the defined value. Usually used with a soil volumetric water content sensor. Example: When the sensor reaches a dielectric constant value of 10 or more, irrigation will stop. See Set Irrigation by Soil Sensor for more details. |
Close (safety)
| Safety option. Valve will close at the selected time. |
