Does vegging 24/0 vs 18/6 have different finishing flowering times?

If two clones from the same mother were started the same time and vegged for 30 days, one 24/0 and one 18/6, will either one finish sooner because of the difference in light cycle during veg?

The reason I ask is because it seems to me that my plant transitioned into flowering a little slower when the light cycle was switched from 18/6 to 12/12, due to there being less of a difference than if the cycle was switched from 24/0 to 12/12. That would mean the 18/6 vegged plant would finish later than the 24/0 vegged plant, no?

Never noticed a difference. I keep mine under 24 hrs of light now. I need the heat from the light because the veg tent is in a cold garage.

if so, it shouldnt be more than a day or two. not something noticable.

so how long do you vegg your plants???????

Clones can have very different growing patterns without a having a different light cycle.For instance i have 6 clones about 9 weeks flowering and some have big buds less branching,medium buds and a lot of branching,some are an inch taller,stronger and bushier.

if the cuttings are from the same plant they should be similar all the way through.

Jorge Cervantes, the growers' guru, did a study a while ago comparing 18/6 vs. 20/4 vs. 24/0 lighting schedules for vegging pot.
He concluded that 20/4 and 24/0 were both better than 18/6. He detected no difference between the 20/4 schedule and the 24/0 schedule
but suggested the 20/4 just to cut down on bulb use.

I been smoking since 1964. You still the oldest hippy?

im smokin from 65 you must be oldas dirt too

These are theoretical perfectly matched plants I'm talking about. Sure, there are many more factors than simply genetics which determine the strength, vigor, size, and yield of a plant. I am trying to narrow down if there is any difference in ending times between two theoretically 100% perfectly matched plants, due to a difference in veg light cycles.

It's all about botany, finding the point where too much light results in less photosynthesis due to limitations in CO2 and/or the destruction of chlorophyll (bleaching it out). I doubt if anyone here uses a light meter, but they sure as hell have a teaspoon or two laying around, hah! Having said that, I have always done a 20/4 for veg and the growth rate speaks for itself. Doesn't mean this ultra fast growth in veg is due primarily cause of my light drills. It means I can balance all factors to facilitate photosynthesis, and that's without using any cannabis specific foods that contain useless enzymes, amino acids and other crap. https://www.rollitup.org/general-marijuana-growing/9114-spin-out-chemical-root-pruning.html

It's all about the amount of photons received over a given light period. It's not a black and white issue. Give the plant too much and it's worse than not enough.

I can settle this once and for all....

I have a picture of me with 48-inch long hair. Didn't get a hair cut from Dec. 1967 (for my HS graduation picture)
to the summer of 2005. Hepatitis C, thanks to dirty needles, led to chemo that had most of my tail fall out. After the chemo
I let it grow again and now have close to a 2-foot tail. Without the chemo I'd be dragging around a 6-foot tail.
