Also is there many growers doing the 14 /10 thing? and when do they switch to this from 12/12 ?
do u get much more yield ?

huh, really, first the veg light cycly is 16/8 for vegg and 12/12 for flower...all growers do this because MJ uses a photo-period to grow. YOU need to go back and read the basic stuff because this was covered on day one of class

I veg 20 - 4 and have flowered 10 -14 once or twice to bring them inn early as does flowering with 14 hrs of light on in the last 3 weeks or so make much more of a yield? is it noticeably more? anybody grow like this ?

I don't think that there is much to be gained from the 24 hour of light,i dont think the plants grow that much faster than 18/6.The rest from the light of 6 hours has more benefits than 24/7.but i always stick to what i know works i and i think that 12/12 gives me the best yeild.But this really all depends on the lighting used and the grow room conditions temps humidity ext.If i flower at 2 ft tall and dont get a min of 8 oz per plant from a 600 hps then im not happy,i do two plants per 600 hps two sets of two under 2 600's...............................tyke

yeah well thanks for your input towards the topic i think sticking with 12/12 for cost of electric is the ticket..
do u scrog to get that type of yield results, i too use the same light but would put in more plants and veg less

18/6 is recommended for optimal vegetative growth, and you switch over to 12/12 after 6-8 weeks (or longer depending on the strain) to induce flowering.

is that your method? sounds pretty L

Yeah, right now my seedlings are on 18/6. The 6 is necessary because they need a no-light period because of their photosynthesis cycle. In layman's terms, they need time to rest. 18 hours to 6 is the optimal circadian ratio because it gives the longest amount of time under a light possible while still giving the plant time to 'rest' and get ready for the next 18 hours.
14/10 is more natural, that's more of the day/night cycle a plant would see outside, but you'd theoretically have less growth due to less time under the light. The decision to light 18/6 is a result of the culmination of experience of many, many people growing for many, many years, and it's a tried and true method.
You WILL have to switch over to 12/12 for flowering as that is what tells the plant to start creating the buds. 12 hours of light a day is still plenty for the plant to photosynthesize during the flowering stage.

your a sheep- many many many people grow 20/4 which is proved better than 18-6and also flower in 14/10 not 10/14 as u did say. stick u with what u know though or you'l get confused

first off plants dont rest lol and secondly its all about power you got lumens why people run 18 6 schedule is thats close as your goin to get to mother nature sun rises 5:00 and sets giving you in around 18 hrs of light in the summer give or take as your plant reaches fall it loses light changing plants hormones to trigger flowering
if you really wanted to think about it for a moment you kinda should run a schedule 18/6 flip to flower 12 / 12 this is the fastest way to trigger flowering as you get into late flowering in reality you should go like 4th week 11 1/2 light 12 1/2 off and and lowering your lighting as weeks go by to final light schedule of lets say 11 hrs light 13 off
thats what i do and get 1130 grms dry per 1000 watt light

Their are alot of people who grow 20/4 to keep it short and more bush
But it is not proven that it is better like you said ,

and prob the people that do are running cfls and florescents but you start running wattage and see heres my girls useing like 14,000 watts including fans exhaust C02 this is on 18 /6
3" clone and in 14 days flipping to flower couldnt see runnign 24 hrs for anymore gains other then having problems

I do the 18/6 to 12/12 also and have had nice tight node spacing and all
i dont really see the benefits to run the veg time longer besides keeping them shorter and a little bushy
but imo thats not playing an overall part in yield anyways ya know
iv had small plants put out more then some bigger plants and vice verse
imo its just the way you grow and what methods you use to help increase yield for ex , like lsting or scrog , suppercropping ect.

"its just the way you grow and what methods you use to help increase yield for ex , like lsting or scrog , suppercropping ect"
this is very true I do lst and have to keep my plants small and bushy, also bought that book where they did the grow in the university of london"on a roof top glass house" and they had reckoned that 20/4 was best and if when things heated up a bit to much around noon each day they would switch the lights of a couple of hours during veg and back on again, so as you say eaach grow room is different,
I still wander is it not better for yield to run a couple of hours extra during flowering especially the last 3 weeks as in 14/10- it has to be? i'm sure it will add on a few days of wait though which at the moment def isn't my top priority,

WTF is wrong with you? You post and ask for opinion on a subject. People respond and tell you what they do/think about it, and all you can do is offend them? I don't get it.
BTW I do 18/6 and 12/12 like most people with great results.

MJ does NOT need a dark period during veg! This is a common myth! I have done numerous tests and each time the same results. There is no noticable difference in plant height with either method however under 18/6, the plants stretch more. Under 24/7 light, the plants produce more internodes. More intenodes means more bud sites, more bud sites means more bud. Those who claim 18/6 is better almost certainly have never done a side by side test to find out the truth. I have tested this theory with 12 different strains, sativa's, indica's, hybrids and it makes no difference, you want more bud, go 24/7, you want more height and stretch, go 18/6. As for flowering 14/10 etc, there have been lots of study's on the subject and the facts prove time and again that 12/12 produces more bud. A few strains respond well to a last week change to 11/13 (light/dark) to simulate autumn/winter and this provokes a defensive response from the plant which then produces more resin/oils but with anything scientific, testing is the only way to prove these things. Having done side by side tests many times the facts come back to Veg 24/7 @ min 3,000 lumens per sq ft 6,500k, flower 12/12 @ min 5,000 lumens per sq ft 2,500k Peace W

I don't think you have any idea what you're talking about. Scientists have proven that with photosynthesis, plants need time for things other than the light receiving part, and they DO, in fact, need a period to "rest". 20/4 may provide enough time for this to occur but I prefer to stick with the tried and true method of 18/6. Tender love and care and making sure your plant receives exactly what it needs (18/6 is closer to the more natural 14/10) is much better, in my opinion, than trying to just grow your plant as fast as possible. Growing marijuana should not be about monetary benefit, it should be about a close relationship with the life you are helping to create, and the mutual benefits of this symbiotic relationship. Stop being greedy and do it right.

If your plants are stretching than you are not providing them with enough light.
