24/12 day night cycle shortens flowering time?

So I had a thought about flowering. Since cannabis gets its direction from the night cycle, you could theoretically cut 6.5 days for every 30 off of your flowering time. Cutting an 8 week flowering time to 6 weeks and a day.

If your day and night cycle was 24-12 the plant would still see the 12-hour night and flour like normal but it would be getting more hours of sunlight for week then in a 12 12 schedule.

So I decided to do some research and see if there is anything out there to corroborate my hypothesis. And I found this:


I was wondering if anyone has any thoughts about this? Or has tried it? I'm about to start flowering and I like experiments.

I'm skeptical, sounds too good to be true lol. Keep me posted on the progress. 👍🧐

From a logical point of view it sounds like it would work. From a grower's point of view it sounds too good to be true. I'm interested, are you going to put it to the test? Hell if I can swing it, I may try it myself. Awesome post. Keep good stuff like this coming.

OK... So I was doing some research and I fell down the rabbit hole on light. I watched this 45 minute long video from Dr. Bruce Bugbee from Apogee Instruments. He broke down how cannabis absorbs light and the 8 things you need to have in the sweetspot for all grows, really informative. I recommend watching if you like all the science that goes with growing (link below). Any way, he goes on to explain how the key is the DLI, or Daily Light Integral, and the amount the plant can take. PPFD is the density of your light per second that is hitting your surface area. DLI is the amount of PPFD in a day cycle. They found that production tops out at around 40 DLI and the plant has no further benefit from light.

Basically, if you download a light meter app. You can see what your light is putting out and adjust accordingly. I have my light at 93%, with the IR bar on but not the UV, and have 3 feet between my lamp and closest top. My plants are getting 43 DLI over a 12 hour period and they are loving life. After 40 DLI the cells need the night in order to recover. So the 24/12 technique will work but for someone with a light that has a lower PAR value.

I used the app "PPDF Meter" to see my LUX, PPDF, and DLI. The screen dimmer sensor in the phone is how it works. Helps with light power, angle, hight.

Also, BEST LIGHT OF ALLLL TIME
