I wanted to pass on the results of a little experiment that I have just completed as others might be interested in the info.
I wanted to know how many days it took from the time my plants were exposed to 13.5 hrs of daylight before I began to see the first flowers and then, the first buds. I chose the daylength of 13.5, because thats the daylenght I assumed I had at 38 degrees on Aug. 1, which is the date I normally see flowers. Ive seen this in several daylength charts for my lat.
First let me say that all 4 of the plants in my experiment are mostly indica, over 80%. 3 cream caramel from sweetseeds and 1 Sadhu from Mandala.
On July 3, I began setting my plants in the grow shed for a period that resulted in 13.5 hrs of daylength . On that date, the plants were fully in the veg stage. The first visible changes in the plants came 4 days later, when the small shoots in the branches began to thicken and change color to purple. The first real flower appearance was on the 11th, 7 full days after I began the dark treatment. The first real bud appearance occurred during the day of the 14th of july, eleven days after the 13.5 treatments began.( I have some pictures showing these flowers but cant upload, ill continue to try)
My conclusions after this rough experiment were that it took about a week after 13.5 was reached to see the first flowers and 11 days or more before small buds were observed.
Shorty after believing I had leaned something, I made a discovery that threw my 13.5 hr belief into chaos. At my lattitude, 38, first flowers for indica strains are seen by Aug 1 generally. Given that my results would indicate that it takes about a week for flowers to appear after appropriate light levels are seen, logic would suggest that here at this lat, the trigger date for flowering is approximately July 23, or 7 days before 8/1.
Today is the 16th of July, and according to sunrise/sunset as listed in the daily paper, sunrise is 6:29 and sunset is 8:59, which is 14.5 hrs. It appears from following the sunrise/sunset times for a week that I am loosing around 3 minutes of daylength per day, indicating that a week from now, I will be at about 14 hrs and 7 minutes of daylength, which I can only conclude that this is the daylength that at my lattitude, will trigger flowering. 14 hrs and 7 minutes sound like a long daylength to me.
My real problem with this number is that i disagree with the papers assessment of when sunrise/sunset begins. I would add at least another 30 minutes to their length because the level of brightness at 6:15 am is significant, as it is at 9:15pm. This would mean in real terms that my indica plants are really being kicked into flower around july 23rd at about 14.45 minutes of daylength, and that is very puzzling to me. Isnt that extremely high? (yes, i was too during most of this experiment)
Anybody have any thoughts or input regauding these astounding findings and conclusions?
