24) Watering Min:Sec. This is the duration in minutes and seconds for each watering cycle.
Set-up Growth Cycle
Harvest-Master uses the term "Growth Cycle" to mean the day and night lengths the plants are under.
Harvest-Master supports three growth cycles, Vegetative, Flowering and Fruiting. The length of "day"
and "night" periods is controlled by the climate settings above. To change the growth cycle just select
this menu option. Use the arrow until the correct cycle is displayed, then OK. Press EXIT to exit.
1) Vegetative. This should be long days and short nights. Most plants can not handle more than 18
hours light per day, so the default "day" length is 18 hours and the night length to 6 hours.
2) Fast Flowering. Setting the length of night to at least 12 hours induces flowering. Normally there
would be 12 hours day as well, but for rapid flowering and early harvesting, reduce the day down
to 6 or 8 hours. Harvest-Master default is 12 hours night and 6 hours day.
3) Full Flowering. For maximum yield, a 12 hours light and 12 hours dark for at least the last three
or four weeks of flowering (or fruiting). Default is 12 hours day and 12 hours night.
Set-up CO2 State.
The purpose of this is to allow you to suspend CO
2
use. This is useful if you run out of CO
2
(or LPG if
using a burner). When CO
2
is suspended it does not try to execute CO
2
cycles. If Harvest-Master tries
to dispense CO
2
but the concentration does not rise, it waits for 10 minutes and tries again. If it gets
three “Not enough CO
2
” attempts in a row it “suspends” CO
2
. It will not try again until the next day
starts. You can start CO
2
again by using the CO
2
state menu option to change the CO
2
setting from
SUSPENDED to ACTIVE.or,….wait until the next day when Harvest-Master will try again.
Set-up Unit Time.
Harvest-Master's internal clock is not restricted to a 24-hour day. The length of the Harvest-Master day
is determined by the values entered for Vegetative light and dark hours, Fast Flowering light and dark
hours, and Full Flowering light and dark hours.
The dark period ALWAYS starts at 00:00. Clock setting is 24hr format
When you set the time the display will look something like:
10:45 0600/1800
Light 1315->Dark
The time is 10:45 in a day with 6 hours dark and 18 hours light.
It is “Light” with 13 hours and 15 minutes to the “Dark” point (midnight in Harvest-Master time).
Use the “Time calculation wheel” to work out the correct time to use. Instructions are provided
on the wheel.
(If you have lost the calculation wheel!)
Suppose in this Vegetative cycle, you want the lights on from 4pm through the night to 10am, so the
lights are off during the hottest period of the day. “10am” real time has to match up to
“midnight/24:00” in Harvest Master time.
•
Work out how many hours/minutes you are
before
or
after
10am
now
, and set the Harvest Master
time
that much before or after midnight.
•
For example, it is now 1:00pm. That is 3 hrs after 10am.
•
That is 3 hrs into Harvest Master dark period after midnight.
• Set Harvest Master time to 03:00
If you are in a Grow Cycle with other than 24hrs per cycle, the Harvest Master day will keep getting
