would the point be to get denser nugs in the same total weeks due to extra light time, or to shorten harvest time by 56 hours?

56 hours is still only 2 1/3 days over an 56 day cycle... doesn't seem to me to be all that signifigant, barely even the difference people wait depending on their trich color preference.. On the other hand, im not trying to be discouraging at all, and you never know until you try and logically it can't hurt? Anyone see how it could hurt?

opposed to a 12/12 schedule wouldn't it be 4 3/4 total days sooner? 1(12 hours light) + 2(12 hours light) + 3(12 hours light) + 4(12 hours light) + 3/4(8 hours light) = 4 days(56 hours light). I think the math is probably still not correct, as giving and taking hours surely effects things. Math was never my strong point, always enjoyed other subjects much more. its probably showing. lol

Maybe I am just looking at it wrong.

Still not a real big increase, but a little.

I have no idea if it would hurt. Never tried in a scientific aspect.

Denser nugs. Same amount of time. When you think of a "day" as 13 hours it's almost 4 1/2 days. If you did a 14 hour day it would be 9 "days" of extra light in the same 8 week cycle. Basically a 9 week cycle crammed into 8 weeks. Wat-ja-thank?

In a longer flowering strain. Say 11 weeks. It's : 77 extra hours if 13 hour days. 154 if you did 14 hour days. So you have the ability to add 11 full 14 hour days in an 11 week cycle. Anyone else got any thoughts on this? Done any work with this?

Not sure what's going on... Adding an hour of light during the flowering period is what I'm gathering...

You don't want to mess with the light cycle to much, it could result in a hermie.

You can add a hour if you want, but it won't save you any significant time.

I actually cut an hour in the 2nd to last week, and cut 2 in the last week. That's what happens naturally, there is less sun available near harvest and it really focuses on finishing up.

If you want to try some funky cycles go ahead, there are plently to choose from, 6/12 will definately shorten the flowering time, but doesn't result in as much yield.

I think the big thing with 12/12 is that it gives you an amount of time, that will change the plants from veg to bloom in the shortest amount of time, while still maximizing the amount of light time for growth. If you really wanted to , you could gradually change your plants over from veg to bloom, by takeing an hour off the veg every week after the first couple days/weeks. This would just simulate what happens in the fall outside. But this wouldn't trigger the plant to "CHANGE NOW" the way that 12/12 does.

I think that the subject is adding hours for higher yield...

There is a method for outdoor growing where you begin flowering indoors, and after 2 weeks when buds are forming you move them outside to finish out the cycle. You can pull down unlimited amounts all summer long, since the light hours are close to 12/12, but hermies are possible.

If you wanna look further into it, you can put flowering plants outside in late spring and harvest before summer, and continually put flowering plants outside to pull them down before the typical harvest time.

I wasn't talking shorter flowering times. The plant wouldn't finish earlier based on a 13/11 cycle would they? An 8 week strain would still be 8 weeks right? Just with 56 extra hours of light. Thought that would produce denser budz. I couldn't see doing anything to drastic. More curiosity than anything. Figure, if budz grow in "daytime"; Wouldn't the girls benefit from an extra hour a day. I'm sure somewhere in the world there is a naturally occuring 13/11 cycle. Alaska has night for almost a month and daylight in the middle of the night.

Just a thought, glad it got so much discussion. I think common sense says anything more drastic than 2 hours will probably cause stress. But would less than that stress them? If it can't, then it's got to have some growth benefits. However small.

Where does Marijuana THRIVE naturally? Seems like following the daylight schedule of such a place would have ideal conditions. Anyone know?

Marijuana THRIVES on 6 of 7 continents naturally. ;)

The extra hour wouldn't get you much extra yield and might promote vegative growth, i've read something about it, but I'm not too certain, so I won't talk about it.

So probably not a good idea it sounds. Good to know. Now if we can all get together and come up with a strain that will grow on the North Pole. Hmmmm.... Let me think for a minute.

Actually now that you mention "where does it thrive", I remember a thread from some Norwegian guy that thought he knew everything about outdoor growing. He said that part of the reason his plants were so tall was that in Norway they have longer days. It is an interesting idea.

Ive done it twice started flowering inside then moving them out, i found anything less then 3 weeks flowering inside and they reverted to veg,the clones put out at same time as flowering plants had nice buds,while the re veg ended up molding at the end,for ideal i find it is just under 4 weeks flowering inside then out,i even tried a few with 24 hours darkness after 2 weeks flowering then outside and they did better,but im sure it is all strain specific,i think a strong indica like chemo would stay in flower after a few weeks,i put 2 in a small container flowerd them for a few weeks left them in my evestroughs,went on hollidays came back and they were small compact juicy nuggets.but they were really small when i put them in flower,they were clones from a mother that wont go past 18 inches in height.

That's cool. I plan on doing it as soon as I move out to the country.


I guess latitude would be a considerable variable. Here the summer solstice only has 14 hours of light... Some places have longer daylight hours.

Short fast slowering indicas definately have a better chance using this method.

so now that i have read the last 30 pages im going to start a grow tm before i start though is this process able to be done with Cfl Rather than a HPS light? the area im working with dosnt have the best vetelation so i think an hps would get a little to hot i am going to do 10 plants 2 fans same exact nutes just debating on the lights

With Cfl's, I wouldn't advise doing 12/12 from seed. Won't get the same level of growth as a HID system. Cfl's really don't require any ventilation so even a simple fan is sufficient. Keep the bulb about an inch away from the tops. The more the better.

I think if you induce flowering to early; You'll be disappointed months later with your harvest. It would be as quick as mine no doubt, just not as much or as dense. I'd suggest letting them get to a foot under cool white cfl's. Then flowering them. Not sure your space size, but I'd veg em' a little bit before flower. Would give you time to add more lights as well. Look for high wattage and luman output. Like I said the more the better.

Might want to look into some training techniques. Would make lighting the area a lot easier with an even canopy. Maybe even a SCROG. Hope I helped.

well im planning on using the same nutes and everything but if i purchased a 400 wattt hps my grow are is about 10 feet tall 3 feet wide and 2 feet deep have a fan on the floow and above the plants and a bulb above i would do a 400 hps but then i can only do 3 plants right? and either way i was going to veg them for about 2 weeks then switch

Why only 3 plants? I'm doing 25 in only 8 sq. ft. I actually have a little leftover room now. A 400 watt system will do you nicely. They still get hot though. But much easier to cool then mine. I'm assuming your doing soil.

With little sq footage. I'd suggest doing say 6 plants in a Scrog application. Gives you one per sq.ft. You'll want more soil than that no doubt. So I'd look sore something square and one foot by one foot. Look for height too. No rule saying the soil can't be narrow and deep. As long as there is soil. With 10 vertical feet, you could pull off a 2 foot high container. Shit, making one will probably be easier and cheeper. Them put the screen a foot above your medium. Your light 16 inches above that. Waalaa-a grow room.

In the future. Please post these types of qeustions in a related thread. This thread is about SOG growing and the like. Hope I've been some help.
