Just shittin, but ive been meaning to at least read up on the 14/10 flower using far red spectrum right before lights off. I know little to nothing about it but the concept sounds intriguing... if nothing else to get a different perspective

ive watched a youtube grower do an led test with the different spectrum throughout the day and he said the plants responded but had no real significant increase or really didnt bring any traits out like he thought

Looks like 18/6 for the win according to the poll
both are equal votes btw(for now)

you can bet if 18/6 was more productive than 24/0 I'd surely be using it.(for the 23 cents daily savings even)

24 hours on will metabolize vegging plants at a higher rate.

Less light would allow plants to demand less, less food, less water, less c02, less cooling, less air flow for example, but if not provided to the more demanding schedule of 24/0 and plants suffer..
plants grow to their weakest resource. In a weak room 18/6 or 24/0 is not the limiting factor.
If a room has correct controls a 24 hour lights on in veg will be more productive than a shorter light schedule every time.
if plants are suffering from 24/0 and not from 18/6...check the other controls to be sure you are providing resources correctly.

Yea what i read was similiar, that gains can be technically had, however it took longer to ripen so nothing was truly gained.

So just a thought, what would happen if you stayed 12/12 but used it at end of day, could benefits be had that way?

It all works the same I'm the end

Amen! So many folks act the opposite that any single error could herm a good plant. I always laugh at that, how do these folks think she survived for eons before the modern indoor grower?

I always say, remember "weed" is NOT a slang term...

sorry it was 12/12 schedlue he decreased to 12/12 over a week or two then messed with the spec throughout the day. i shouldve added that it wasnt at 14 the whole flowering cycle

I use to over think it
Now as long ass my temp is from 66-86 and humidity around 40-70
Plants are happy

18-6 for veg
12-12 for flower
Why make it harder
I don't even set my timers anymore
Have 2 rooms 1 for veg and 1 for flower

bc sometimes a better outcome awaits with a little more effort lol. i was reading an article earlier and they were explaining that some of the sativas theyve collected over the years do best under 10/14 have more compact dense nugs

I doubt that
Sativa strains in general grow air
Add less light and I don't see how that would make denser nugs
well that was their results, i can see how it could. less light and they wont stretch as much or if they do the way they stack wont be so thin with less light. makes sense to me.

here my take .. trying to keep it natural ...
18/6- veg
14/10 -preflower
12/12- flower
11/13 -ripen
10/14 -finish
this mite be an overkill , see how it goes ...
I've read what seemed to be credible reports of side by side comparisons that showed that 18/6 was the clear winner for the veg period. I know that DJ Short days to flower under 11/13.

I've heard of people starting flowering with a very short day and then going to 13/11. It does make some sense. Outdoors plants start flowering long before the Autumnal Equinox around Sep 21 when the day and night are around 12/12 so it's definitely not necessary to flower. It might be better to just do the 24 hours of darkness to start flowering to get the sudden transition and avoid confusing the plant and go straight to the 13/11 where you'd get more light during flowering.

According to DJ Short the 11/13 gives a more aggressive flowering plant and doesn't seem to affect yield in any negative way. I've light depped greenhouses on 11/13 and it shaved around a week off of the flowering time so it could even improve your yield giving you almost one full harvest extra at the end of the year. I've heard people say that they're crops are ready a week earlier with CMH too. Imagine cropping two weeks earlier? 52÷8= 6.5 crops a year. 52÷6=8.66 crops a year. Who knows if the math would hold but 3 more cycles a year would probably make up for any loss in weight from having less light in the day period and then some.

i agree, and if you pick the right strains, im sure youll get the results you seek :)
