Can you make up your own grow hours??

I just had this idea on lighting. Could you like have long ass days? Normal example, grow 18 hrs on, 6 hrs off. Veg 12 on 12 off. Doesn't marijuana need at least the 12 hours to begin budding? Say, for example, during the grow you had like 30 hours on and 6 hours off, would the plant still be healthy or get stressed from the hours. And then during veg, could you have lights on for like 20 or 25 hours and have 12 or more of darkness? Would this increase growth or bud size or make it grow faster?? Would it stress the plant out? ( It doesn't have to be those exact hours, i'm just saying examples ) Just a high idea I had this morning.
:peace:

I think you mean 12/12 for flower and not for veg.
Yup, thats what I mean. I dont see anywhere on the post that says what u said but ok. I'm just wondering if it'll effect growth like I stated in the post. would it just grow faster or bigger? will it effect potency? Will it cause stress if hours are too long? Does it affect bud size?

Because 20/12 is .75 days per earth day.

167% the light/day... for photosynthesis... compared to 12/12.

It'll make it longer, and increase harvest. I'm sure it might be beyond a certain point? More night isn't going to help a lot. Light + CO2 + H2O + Nutrients + O2 = plant(in no particular order).

i have read of people doing stuff like this but have yet to try it myself, what they do is do a week or 2 or 12/12 until the plant starts budding then switch to 14 on 10 off, i guess its not enough of a change to trigger the plants back to veg and you can get bigger yields, i think i read that in high times, as far as the super long days for veg just leave the lights on constantly, the whole 18/6 thing is because ti saves energy mostly and it allows you to let the room cool if say your growing in a hot climate or some shit like that, i have heard of people doing weird things when budding but from what i have gathered the tried and true 12/12 is your best bet, like i have heard of like 24 on 12 off for flowering but im not sold on the technique, from what i have seen it tends to make the plants do funny shit like go hermie or make long stretchy buds that never quite finish, i am going to try the 14/10 flowering schedule though, it sounds like it has some promise

IMO, although we are always manipulating nature on our indoor grows, sometimes we get a bit ambitious as to how far we can take it. One of things we play with are the photoperiods, how ever in an attempt to make a day longer or at least make a plant think that, you are in essence trying to rewrite the core formula in its DNA. This is impossible to do in our lifetime, it would take thousands of years of hermies impregnating themselves and creating this genetic defect in a plant that would bud on that schedule. So unless youve got ALOT of time( a few hundred generations worth ) this isnt a worthwhile experiment.
In my opinion that is. Just my little scientific input

I disagree,

Plants produce the required hormones to sex from extended darkness. There is no proof the light period has a significant affect on this, given normal circumstance.

I do not see how your input is, in any way, scientific(predictably, reproducible, etc).

I see your point and I did say in my opinion. I have no experience with this particular lighting schedule and am all for advances in technique, especially if it means more bud sooner. But I think if you extend the nights beyond a certain point, not sure what that would be, this would indeed create an immense amount of stress and in doing that you have a higher chance of hermies. My point is I think it would take generations of that plant to adapt and produce well on that schedule. I get the point about more light more growth, but I think a plant at a certain point the plant needs the dark to in essence rest and use the energy the collected during the light hours. I have done 18/6 and 24 hour cycles on my veg and with very similar results actually leaning in the direction of the 18/6 as far as growth goes. But like I said this is my OPINION... I was just giving you my input on the question you were looking to answer.....

I was more talking about past 24hr long days. Like 30hr days or something like that. Like 24 on, 8 off. Shit like that

I just dont see much point. 24 hour timers are easily set up and run themselves without having to tinker with them. I think the only thing I would really mess around with is running a HPS or MH during off peak electical hours if your electical company charges different rates at different times.

Digital timers have brought us into the new millennium :dunce:

I know you can do the opposite and have a 12/6 schedule to speed up your flowering (creating an 18hr day). It will fuck up your personnel schedule though, but apparently will reduce your wait for harvest by 25%. I haven't done this BTW, but someone more experienced than I told me so, so it must be true.

I don't understand the significance of making the day longer though.(?)

longer days, longer flower period, more light, bigger yields.

creating an 18hr day would mean shorter days, shorter flower period, less light, smaller yields.

do you want less bud now or more bud later? personally im interested to see how a longer period compares based on yield/time.

Your talking just vegging right? Obviously if your day is longer than 12 hours your not flowering, I assume you understand that.

Do you also know you can keep the lights on 24-0. No night. That's the fastest way to grow in veg. This way you can create a month long day if you want.

I must say I'm still a little confused.

Ya that is a different way too. I'm not really talking necessarily about longer hours, but like your 18 hr day idea, im just talking like making up your own days. That is a good idea tho.

Well i was just giving examples. During veg and flower. 24 hrs tho is a alot of energy with mh and hps. But like the other guy said maybe like a 12 hour day and 6 hour night. Is 6 as low as you could go without messing up the plant during flowering? Would that speed the ripening up or influence the yield?
