No Dude, Re-read this part: It is important to start these changes at the three-pairs-of-leaves stage and continue for two or three weeks, before reverting to standard conditions

There are a few solid studies that show plants do better with daily darkness as opposed to 24/0

It is always a good idea to give the equipment(lights, fans, pumps, etc.) and plants a rest.

As always seems to be a matter of personal preference.I also say that mimicing mother nature inside defeats the purpose as with indoor conditions you want to exceed mother natures options to get the speed and quality mother nature doesnt allow for.Hell if I was growing indoors and had to wait 6 months to harvest Id be pissed lolTrial and error brings preference and content.

I dunno fletch you gotta remember plants are adapted to the sun and its cycles.

But would you also not see the side, as I am a clone grower from clone growere that go back years from original seed, that through forced adaptation of indoor growth a plant can be adapted to an inside controlled environment in the same way natures selective adaptation has occurred. A sort of if you will evolution to what generations of growers have trained a starin to be which is genetically passed from cloned mom to clone baby then to next generations also??

VIDEO man you are covering something i am very interested in!

I was told by the guy I bought my seeds from (local head shop) that 24h lighting will give approximatly 70% males, while 18/6 brings it to around 50/50 and 16hours 40% chance of males...Those are obviously rough stats and very dependant on the strain and other conditions.
I found it particularly strange because I haven't read that anywhere, or seen any sort of tricks to help the male to female ratio.
I posted something about it on a 24h vs 18h lighting debate and people just politely called me a moron. Thats ok though, I can roll with the punches...

Glad to see some info from a credited fella backing up my thoughts...

Cheers

This is what I am afraid of. We may be destroying the genetics of marijuana. Over time the strain might change, better or worse.

Maybe so but for indoor grows a time scheduele that allows fro optimol production and yeild ina know faster pace does have its advantages.I always am impressed by those out door growers who can put so much time and effort into such long grows but have always figured if Im not growing an acre or more of bud I can get the same yeild indoors with 3 harvests in the same time period with 3 stages of succesfull satifaction without 60% of the effort or stress.Im a believer in the 24 hours on cycle for starting then a slow darking period following a more natural light cycle or season change but find the 24 hours gets me a jump start into real vegging.I do respect others preferences though so Im always saying if it works for you go for it if not maybe try what the other guy does.Good grows either way

I do have a friend who uses all these guidelines on all grows, and claims a 90% ratio of females. That is impressive.

Filthy, I think you would be hard pressed to outdo mother nature, as I re-read your post, I kept wondering if you were growing for personal or for profit, it sounds like it's for profit. How can you out do mother nature, a well grown plant outdoors can yeild over a pound, a well grown plant inside can yeild....ounces.

I could think, and wonder if 24 hour light would speed up vegging, however from all the reading I've done, I have never found any info to support this theory. Only an increased electric bill. I also agree with GardenKnowm that giving the equipment a rest is important too.

Lando, it IS interesting that a company put the time and expense into this study, you need to utilize all the info they posted. A 90% female ratio would be awesome. I think from seed, a normal ratio is like 60-40.
Peace

So right now I'm slowly bringing my veg hours from 24/0 to 18/6 half hour a day. for some of the reasons posted in this thread and also because with the 24/0 my humidity runs 30%-40%. I'm down to 2 hours off right now and it brings the hum up to 50-65% and slowly goes down during lights on, which I don't mind as I would like it a little higher then 30%.


Is this a decent way of changing cycles gradualy or should I just go straight to 18/6?
