Aloha,
I saw people asking about the growing seasons in hawaii in 2 separate threads, and when long season starts.
This is the tool I use to figure this information out
http://aa.usno.navy.mil/data/docs/RS_OneYear.php
Just input hawaii then the town and hit Compute Table
i'll post an example of how to find information on your area, lets use mililani as an example
inputting mililani and calculating sunrise/sunset times:
march 15
rise 06:40
set 18:42
daylight hours: 12:01
do the math 1841 - 0640 = 1201
april 15
rise 0613
set 1852
1852-0613 = 12:39 daylight hours
see the daylight hours rising?
may 15th
rise 0554
set 1904
1904-0554 = 13:50 daylight hours
june 15th
rise 0550
set 1916
total daylight hours: 13:66
july 15th
rise 0559
set 1917
total daylight hours: 13:58
the daylight hours start building up until june-july when flowering will start, in the best case scenario you choose a good planting date in late march, thru april or may, and the plants have some time to veg until flowering is triggered
i suggest you all use this table for your specific area and find out the best planting times
good luck this season folks
