Light leaks in veg?

I have always wondered this myself and i hope we have an answer soon!!!!

If it does somehow disrupt the plant's internal clockwork or "circadian rhythms," then
perhaps that would argue in favor of a 24/0 cycle......no dark period to disrupt!!

i'm gonna search the literature for an answer but really i don't recall ever seeing this
question posed or answered......yet i shall search nonetheless!!!!!

kind regards from a guineapig

Mohter nature doesn't provide a solid veg period of perfect light, cloudy days are natural. I'd be willing to suggest that any strain bred for outdoors wouldn't recognize a trigger, but strains acclimated to indoors might. The only trigger that's important is flower, at least 10 hours of dark until finished - if they see a shortened night they may try to kick back into veg, and if it's sporadic they might hermie from the confusion. Constant fluctuations while in veg may confuse them enough to slow them down to think about what to do, but I don't think fluctuations in veg phase need be a concern as long as they never see 10 or more hours dark, then back to the original veg settings.

i wouldnt worry to much, as long as it is in veg, you're ok.

i never understood 18/6!! its pretty much settled that 24/0 provides faster growth, why slow yourself down??

Wasn't really looking for a "24/0 works just fine" solution, but for information on whether somewhat erratic light cycles -- or rather, some small interruptions during the dark cycle -- would bother plants in vegetative growth or otherwise cause negative effects.

Right now I have no needto switch out of 24/0, but with California/PG&E's baseline pricing schedule and with summer conditions coming up (without A/C), it's under consideration. Currently running 250w MH to veg for a 600w-1000w HPS flo, but might add 250w more to keep mothers and maybe extra vegging capacity (I bought a dual 250w MH electronic ballast, currently running single output).

What 1toke said.

There is no such thing as light leaks in veg, figuratively speaking.

If you've had moms under 24/0 for a long time you may see some auto flowers when dropping the amount of light hours... is the only negative I've noticed. Only with finicky strains...

 

[Guest]

no it will not

If I were to put my vegging room into 18/6, 20/4, or anything with a dark period, would a light leak cause harmful stress or cause anything negative to happen with the plants, like it would during flower?

 

[Guest]

Case in point - I work with 20 moms' clones in perpetual cycle and juggle plants, pots, lights - all the fun shit, and never have I seen probs in veg. They may get half an hour more light, if anything. It's a weed, not rocket science- in my experience they are very forgiving. Just set up a routine and try to keep it constant until you're ready to flower them.

Good call unicorn & stretch.

Seems to make sense, especially the:

Since there isn't any hormonal changes to be made between 24/0 or 20/4 or 18/6 or whatever, since veg is veg.

Thanks for the input, everyone!

ive read that 18/6 will give you more females as opposed to 24/0, in addition to it cutting down on electric bill/heating issues. ive also read that the female male factor of light schedule only comes into play AFTER the first true leaves appear (first set of 3)

I think I also read something along those lines, in Jorge's book. Might have to look into it again, but it'd be almost impossible for me to do any conclusive testing. Too late for this cycle, anyways.

I concur. I used to run my veg cycle 18/6, but I would flip on my overhead flourescent work lights any time I wanted to during the 6 hrs of darkness. It has absolutely no effect on the plants. Frankly, the only good reason not to run 24/0 is because of heat. In SoCal its just so freakin hot that the 6 hours of off time really helps get the temps under control.

The dark period is the critical element. Once the plants start seeing around 10 1/2 to 12 hours of darkness, flowering gets triggered. If you have leaks, or fart around in your room with the lights on during "lights off" after you've forced flowering, then you are just asking for hermies.

nothing is set in stone...even what you read...so many things i have changed over the years...so much bullshit i thought i had to do to grow pot...its art... the parameters set by you

Very well stated, Mr. Radioactive.

thats why i said "ive read" for anyone that wants to buy into the information, they could read into it some more.

i use tap water dont let it sit 24 hrs before using chlorine and all
(but hey we drink it too)...i use sulfuric acid as ph down...dont use clone gel...i can go on and on about what the books say verses what works and what other books say that contradict the very book i was referring too
