Photoperiod Adjustment!

alright, it's nice to see some people put up those links where their was actual info, but you'll gotta chill and not attack each other. As 707 said, the point is that supposedly the plant receives more light at once which allows it to create more ATP and complex carbs and other chemicals which helps it build and generate more cells, the only information I was basing this off was if you've ever heard about Alaskan fruits and vegetables, they're fucking HUGE, and i think that has to do (to a degree) with the fact that they have longer light periods. I was so interested in this information, because I have to grow from feminized seeds every time due to extremely tight space requirements, so I don't mind putting in extra time during the flowering phase if the weight and potency and increases even less than proportionally because either way I have to go through the same amount of veg time each run. But it's also very useful to know that less than 12 hours will produce at least somewhat comparable yields, because if your growing a sativa that takes 14 or 16 weeks to flower being able to chop it down to like 9-10 could speed up the turnover by a lot.

NGT, that artical only talks about the 24 hrs. being better than the 18 hrs. of light during veg. it said nothing about having a day longer than 24 hrs. i still think that increasing your day (light hrs.) hrs. to 22 or 25 hrs. of light or whatever is still not worth it because your just waiting longer. of course you get more bud, but at the cost of more TIME.
I haven't done a lot of research latly on it compared to in 2000 -2001 i did a whole lot of research. I didnt find any then and still havent heard of any now.

I'm sorry but theres only 24 hours of light in a day, so if you run for 24 a day, then the light is constantly on, there is no dark period. As stated in that article the plant grows when it is photosynthesizing so if its on 24/7 then its getting maximum growth.

The same thing applies to flowering. You can only flower for a maximum of 14 hours per 24 hour cycle. The lights go on and off at the same time every day and you get the maximum results.

How does dong 24/0 instead of 18/6 cost you time?

18/6 is more costly on all fronts in comparison.

NGT, maybe you misunderstood me. I agree that 24hrs a day gives morew growth during the veg. state. day = 24hrs.
I'm talking about making a day = 34 hrs. every day in the bloom state. 22 hrs. on & 12 hrs. off. every day will get its 12 hrs. of dark. this will keep it in bloom. people say you get more, but i say you do at the cost of time. i hope im making some sense.

well i never agreed in the first place that this was a sensible way to go, it didnt occur to me this is what you were thinking because it seems crazy. You extend your flowering period just by having 14 instead of 12.

there are several references around addressing this flowering photoperiod length (same source ?)
How do I manipulate the photoperiod for larger yields on Planet Ito?

I'm going to give it a try, junked 5 electric timers and got two 7 day digital timers for the lighting and ebb & flow controllers
- the digital timers also permit a much shorter flood period, but the large # of weekly events (70 max on/off feed cycles) makes finding a suitable timer difficult (tempted to use a PLC controller)
