32on/16off and 24on/24off

[Jungl3Jim]

hey all, as always a pleasure

Just out of interest, I've looked around and can't find damn near anything on this..
however..
Has anyone here tried the light schedule in the subject title?
ie, 32 on and 16 off 4 veg, and 24 on and 24 off 4 flower
Would it double grow time, but twice as big.. do nothing.. or just generally fcuk with the poor girls and cause hermies??

Thinking about trying it with a few seeds and clones I have getting started atm.
Worth a try you reckon?

In advance.. much appreciation.. the community here is always pretty mint

Hmmm, a whole series (using clones) with different time schedules would be interesting. Just like people are geared to a day slightly longer than 24 hours, I'd assume that plants are to. I don't know about a 48 hour cycle, I think I'd try a try something more like 36. Wish I had the plant allotment to experiment like that!

You would have to have a mean timer set-up to do all that time keeping. I bet that, like dennis said, if someone did like a 24/6, it might do something better for VEG. But I think that anything other than 12/12 will just cause hermies, like is already a known fact.

'when in doubt, imitate nature' - 18/6 for vegetative growth, 12/12 for flowering ... there are no shortcuts to growing primo pot ... it requires patience, and leaving your plants alone, to grow naturally ... happy gardening :smokin:

[redtails]

I'm sure if it helped any people would be doing it all over. Good luck with your experiment!

Sorry, not worth a try.

Questions like this make me sad; here you are growing or trying to grow marijuanna for your enjoyment or meds and you completely lack any knowledge of the plants biology. Plus you are unwilling or unable to read a book to understand it, because if you did you'd realize why 36/16 or 24/24 can't work.

Virtually all plants (and most animals) have innate circadian rhythms. These are rhythms of biological activities that flucuate over a period of approximately 24 hours. MJ is what's referred to as a "short day" plant meaning it goes to flower when the daylight becomes less. Actually the plant measures the dark period to make the determination to go to flower, and with mj aprox 8 hrs or less of dark the plant vegges and more then 8 hrs of dark the plant will flower.

So trying to veg 32/16 the plant will build up plenty of the chemicals to make it flower during the 16 hr dark period and have plenty of time during the extended photoperiod to try and revert that and veg. Won't grow very well scince it will be in a constant state of confusion, this will probably lead to hermies.
Trying to flower at 24/24 the plant again recieves mixed signals, so it's a no go.

Now there have been experiments with using a shortened circadian rhythm and it is possible to shorten the flowering times of mj but the vegative growth duration is the same, since you can veg 24/0 there is no gains to be had.
Using a 20 hr "grow day" you can flower at say 12/8 (border line dark, would need to use 24-36 hr dark during the switch over to induce flowering). Now for every 6 grow days you pick up 1 calender day. In other words a plant that needs 8 1/2 weeks or 60 days to flower could be finished in 51-52 calendar days.

See you don't want to lenghten photoperiods to speed things up, actually shorten the complete day. Hope this helps your understanding of the plant and piques your interest enought to read a fuckin' book on plant biology or horticulture.
Hope you still think the community is mint, understand that I'm just a cranky old man.

Thanks for the input everyone.. however I have only two issues with the replies so far..

First: Books are written by a person or people who have tried/experimented with a thirst to try new things instead of playing "Lemming" and following the masses

Second: There is no mention whatsoever of trying to "Speed things up". I was only interested as to whether anyone here had actually tried anything of this nature.
As per the following text "Would it double grow time, but twice as big.. do nothing.. or just generally fcuk with the poor girls and cause hermies??"
This is a question on experience.. opinionated degrading comments isn't exactly what I was after.. but cheers anyway.. every opinion counts, however if the world based everything it did on the comments of a "Grumpy old man".. where would we be right now? :wtf:

[sarah louise]

lol Jim, the world is run by grumpy old men.

Sorry Jim,

I did not mean to be so mean to you. The only opinion I gave you was to read a book. The answer I gave you was based on facts, as current science see's it. I did not mean to put words in your mouth about speeding things up, but felt the example that some people have tried or are using a short day technique was the only useful info from radically changing the photoperiod.

To answer your question:
1) it will not double the grow time....it just won't grow and it won't double in size.
2) it will do more then nothing, see #3
3) it will fuck up your girls and probably cause hermies.

I read and experiment, it works out pretty good for me. It's how I know about shorten grow days. I've lived my life by a simple philosiphy, try to learn something new everyday, and in my 79 years I've learned quite abit. Problem now is trying to remember it.

Sorry again, but as Sarah Louise points out the world is run by grumpy old men....it just that most of them don't grow pot.
