Hi people,
I have a few indoor grows under my belt now I have used 250w 400w and 1000w HID lighting as well as T-5 and LED. As I consider LED lighting for flowering I read all this information on what type of light to use, how far to place it from the plant, what color or temp of the light is best to use but one thing seems to remain constant, The time cycle. 18/6 and 12/12. I know some people go 24/7 veg but generally this is whats used.
When you consider how sensitive cannabis is to light you have to think maybe there is more to it. I am sure I am not the first to consider this, so I thought I would run this by you and see what you think.
I am sure you have noticed the difference between indoor and outdoor production. We try to re-create Mother Nature Including the light cycle but could it be fine tuned for maximum bud production? I have read the actual amount of lumens a plant receives from the sun is around 10,000 at ground level. Please correct me if I am wrong but if that is true then all that's left is the amount of time of the photo period.
This is what I found.
Hours of daylight at 40° Latitude (approximate center of the US)
April 13:14
May 15:22
June 15:00
July 14:49
August 13:48
September 12:31
October 11:10
November 10:01
Take a plant that has an eight week flowering period and would normally be ready in early October if grown outdoors.
At the beginning of flowering period it would be getting 13:48 of daylight.
At the end of the flowering period it would be getting 11:10 hours of daylight.
Thats a 2 1/2 hour difference, yet we keep it at 12/12
How about this?
8 week flower:
Week 1 and 2 at 13/11
Week 3 and 4 12:30/11:30
Week 5 and 6 12/12
Week 7 and 8 11/13
Maybe this is the key to getting better production out of LED lighting.
Has anyone tried this or have any comments?
P.S.I also found out holding down alt, and typing 0176 will give you ° (degree) symbol
