Yep. It is still 12+ hours of darkness everynight.
I have attached the 2009 light cycle for hilo(closest to Puna they had for the big island.)
Go here for
One DayLight Times.
Go here for
Year tablelight times.
Check out the txt file attached to figure out the next few lines.
So here January 7th tomorrow. You have -
0657 1757
0657 - Being the time the sun rises.
1757 - Being the time the sun sets
So 1757 in standard military time being 5:57 p.m.
So from 5:57 p.m. there is 13 hours of Darkness and 11 hours of daylight. So your girls can continue to flower as long as there is essentially 12+ hours of darkness.
But being outdoors these figures are exact and natural forces and varying factors also must be taken into account. This is just a rough run down.
Then we skip over to March it is -
0630 1830
0630 - rise
1830 - set
So the sun sets at 630 and rises at 630. This being a 12/12 hour light cycle.
From there the amount of daylight increases as summer comes and the amount of night decreases so the
chemical that induces flowering is suppressed by the sunlight light until the cycle continues again and there is longer nights and shorter days (winter).
I think I got that right. lol
If I didn't feel free to correct me. Hope that helps some people.
