HOW TO DETERMINE VPD TARGETS
MIST To determine the target for a particular station, do the following: In the SET
STATION MODE for a MIST STATION, enter a large target. (our recommendation for
early crop mist is 1000). The large target is to ensure the station won’t automatically water
the crop until the grower has determined the daily target. When the grower believes the
mist station needs to be watered, do the following: In the MANUAL MODE, choose the
mist station and activate it while noting the time of day. When the plants need to be
watered the very next time,
(THE GROWER NEEDS TO DETERMINE THIS BY
PHYSICALLY WATCHING THE PLANTS) , note the reading of the Accumulated
VPD for this station in the SHOW SYSTEM MODE as well as the new time of day. You
now have the target for the day. Go into the SET STATION MODE, choose the station and
enter in the new target.
REMEMBER THE PLANTS NEED WATER! NOW THAT YOU’VE
NOTED THE ACCUMULATED VPD AND THE TIME, GO BACK
INTO THE MANUAL MODE AND ACTIVATE THE STATION SO
THE PLANTS GET SOME WATER!
To go the next step with the available information, the targets for each day that the crop
will be under mist at this specific station can be calculated. Do the following: Take the
NEW TARGET and divide by the number of minutes between the two mists. This gives
the VPD per minute. For each daily target, calculate how much time between each misting
for that specific day if the environmental conditions were identical to the first target.
Multiply the number of minutes by the VPD per minute to develop a target for each day.
Hint: If developing a model for mist to propagate young plants, the targets should go up as
the plant grows.
Targets going up mean that the amount of mist is going down.
IRRIGATION To determine the target for a particular station, do the following: In the
SET STATION MODE for an IRRIGATION STATION, enter a large target (our
recommendation for small plant irrigation is 10000). The large target is to ensure the
station won’t automatically water the crop until the grower determines the daily target.
When the grower believes the irrigation station needs to be watered, do the following: In
the MANUAL MODE, choose the station and activate it while noting the time of day.
When the plants are ready to be watered the very next time
(THE GROWER NEEDS TO
DETERMINE THIS BY PHYSICALLY WATCHING THE PLANTS) , note the
reading of the Accumulated VPD for this station in the SHOW SYSTEM MODE as well
as the new time of day. You now have the target for the day. Go into the SET STATION
MODE, choose the station and enter in the new target.
REMEMBER THE PLANTS NEED WATER! NOW THAT YOU’VE
NOTED THE ACCUMULATED VPD AND THE TIME, GO BACK
INTO THE MANUAL MODE AND ACTIVATE THE STATION SO
THE PLANTS GET SOME WATER!
