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
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.
