Not just "No" but "HELL NO!"Awesome, and have you experienced this fabled loss of THC content from less than 12 hours of light?

Not that I've noticed..Awesome, and have you experienced this fabled loss of THC content from less than 12 hours of light?
Do you have any documented research to prove what you say?Awesome, and have you experienced this fabled loss of THC content from less than 12 hours of light?
Where’s your lab results?Do you have any documented research to prove what you say?
Nope! Just your uneducated "feelings."
How about you test your "feelings" in a lab, and then get back to us.
Until then, let's hear some more of your "feelings."
I won’t attempt to debate someone’s 40 year old research that isn’t even your own.In my first post was a quote by Dr. Clarke that started "research has shown." Then he cited the source.
"before hid lighting was even used," HA! that gave me a really good laugh! I imagine that you were not even born when Rob published his research, so you would not know about the use of HID lights.

Clearly genetics and light tech haven’t changed at all since then so the same blanket data must stay true forever.
Everyone else must be wasting their time
None of us would be able to tell our end product is missing a measly 50% of the thc because we aren’t as old as you
That's rough, bro. Hope everything works itself out soon...Today at work I had trouble. I went to the toilet in a nearby restaurant and it felt like I was having a number one from my number two, but the type of number one experienced after you've fornicated. There's more. I was the only person to go to the toilet in that time and when I tried to flush, it didn't work. I took the lid off the top bit and started yanking on the floating device, I remember doing that as a child flooding the bathroom, seemed like an option.. but nothing happened. I walked out feeling very bad knowing the young waitress was not going to get an early finish today. Tomorrow my face is probably on a poster pinned to every post in town ''wanted for shit and run''.
Still, not the lowest point of the day.. night guys.
Both flowered under shortened flower periods. So by your logic, these strains if flowered under 12, would've doubled levels? C'mon guy. Different strokes for different folks.Do you have any documented research to prove what you say?

this quote from RobClarke and the apparent 'research' is ridiculous.Marijuana Botany said:
"Research has shown (Valle et al. 1978 ) that twice as much THC is produced under a 12-hour photoperiod than under a 10-hour photoperiod."

No one is suggesting you are. We all make decisions based on limited info. I think the anti-science sentiments so many people express are cute. They act as if its something to despise, as if their lives would be better without it. They act like a spoiled brats, thinking if he breaks his toy another even better one will magically appear. A brat with absolutely no appreciation of what he has, or how he got it. I'll stick with running the light as long as possible while still keeping the plant in bloom for yield reasons.I'm not doing a scientific experiment. I am though growing more herb in less days with less electricity since I cut my light period to 10 hours several months ago. I thought I would try it and here I am. I do grow under high quality full spectrum white COBs and LEDs, not street lights.
Gotta go enjoy some anecdotal herb. My lights finally turned on!
Global warming is very real, very serious and an incredible threat.
Oh, I'm not dismissing your experience. It's got me, and probably a lot of other people thinking about this. But surely you are getting better with each grow. And you probably grow various strains. There are other variables in play, and we are talking about subtle things here. The thing I have difficulty accepting is that a plant that gets more light will have a smaller yield than one that gets less light. That's an extraordinary claim, and extraordinary claims require extraordinary evidence. I think it's an open question, and I won't jump to conclusions either way.My yield is noticeably up. It just is. Potency is at least as good and plants flower time is a couple days shorter. Been doing some same strains for years. Only time I ever was under 12 hours before was down to just over eleven hours to try to finish full bleed Sativas. Too many folks here are having similar results to dismiss. I just like spending less on power with better results, faster.
I was surprised with the results myself but at this point I'm not suddenly getting that much better. From all I can gather, it is working in intensely lit areas. I'm at just over 10 on at about 45 watts/sqft. COBs.Oh, I'm not dismissing your experience. It's got me, and probably a lot of other people thinking about this.

Sounds like you have a lot of experience with the strains you are growing. It would be interesting if you made an adjustment to maximize the light during bloom on your next run. You should see either an increase in yield, or decrease. When you're accustomed to a certain technique, subtle differences become more apparent. That would carry a lot of weight in this debate.

Well the research is aboutI know it was written over 30 years ago, and the research cited is older than that, I'm still going with Rob Clarke's Marijuana Botany. I give my flowering plants 13 hours of light and 11 hours of darkness.
Rob Clarke says that less than 12 hours of light per day will result in less THC produced. So here it is, like I've copied in threads on this board for years:
Marijuana Botany said:
"Research has shown (Valle et al. 1978 ) that twice as much THC is produced under a 12-hour photoperiod than under a 10-hour photoperiod."
(emphasis added)
So you can give your plants 10 hours of light per day, and they will produce half of the THC they would produce under 12 hours.
Therefore, I give my plants as much light as I can give them, while keeping them in flowering.
