Has Anyone Attempted The 6 Hr 40 Min On/ 12 Hr Off Schedule?

has anybody tried this succefssfully on this sight......if so, got any pics?

no, no experience yet, but its going well (i think) plant too young to tell and haven't really noticed and increase in growth rate which i think you're supposed during flowering. its only been a week of flowering though so i shall i hope for the best. here's what she looks like now, going to transplant here again in a few days to get some good rot growth, suppose i should have done this earlier though.

hey guys I was wondering if I should try this with my grow? I am about to start flowering in the next day or two, and I am also running short on time. On the other hand, this is my first grow, so I'm not sure.

Thats a decision your going to have to make on your own. However if your short on time, why not?

HELP REQUIRED, my timer didnt turn off, it must have broken somehow. anyway i was out and when i came back my lights were still on when they should have been off. therefore the light was left on a further six hours than they should have. i am running an 18 hour day of 6/12. so the plants were exposed to 12 hours of light. what should i do? should i give it a 24hrs of darkness to compensate for the dark period or just resume the timing schedule as normal. i really dont want a hermie? any help would be appreciated.

Resume the normal time schedule quickly.

thanks for the response, much appreciated

ok things just got worse. on friday i had to take a trip for the weekend. my timer was fixed and everything was going fine. i was about to leave when my mh lamp stopped working and i had no time to fix it. i had no other choice but to leave it by the window so that it received some light. the daylight hours in the uk at this time where i live are about 12 hours. this isnt 12 hours constant light for the plant though, due to its positions it was probably only exposed to about 4 hours max of direct sunlight and the rest was low light levels i guess. but the weird thing is, when i came back it looked like my plant had really grown in size. not so much bushy, looks a little stretched now but hasnt gotten very noticeably taller. the biggest growth in 2 days i have noticed under the time i was gone imo.

cos i was running the 6/12 schedule i have no idea what to do. i'm a first time grower and only went on this schedule as it was a way to possibly flower early and seeing as i'm rushed for time i went for it. now i'm unsure what to do cos it would all be a waste if i turn my plant into a hermie. should i just carry on with 6/12 or the 12/12. or maybe i should gradually bring the 12/12 down to 6/12 by possibly reducing an hours light each day until i reach 6/12?

here's a few pics to show its growth. can't really see the size from the first pic but it was about 6" in the first two and now its at least 8"

If you believe that it only got 4 hours of direct sunlight then you could continue with 6/12. The reason it stretched is most likely due to the low light levels that you were experiencing after the 4 hour maximum.

thanks a lot, ye i thought the same about the stretching

I was really tempted to try this schedule but I am already in week 3 of flowering and did not want to stress my ladies. I wish you all good luck and if things turn out well I will be implementing this on my next grow. /subscribed

I"ve never grown before, but I'm going to start small real soon. so i don't have advice. But in theory, it shouldn't stress them too much if you do it right. Most people i've seen on here slowly lower their light schedule for about 18/6 to 12/12 by going to 16/14 and then 14/6. So do it 10/14 then 8/16. By that same theory you shouldn't have to keep it at the same schedule for as long. Maybe a week each.


As I said I don't know about growing but i may just try this on my first grow. I just need to get my CFL's and soil. and something to read the humidy of my grow area.

ok well here's an update. i found out that after 2 weeks of using this method, i had light leaks in my closet (shit!) so now that i have fixed this problem, 3 days (18 hr days) of putting the plant in complete darkness for the 12 off period, i had preflowers. this was 2 days ago. i now am waiting to see how long it will take. on the packet it says between 80-90 days so i shall hope for the best. its a sativa dominant plant so should take a while. will show u guys a few pictures once they are really clear cos i can only use my crappy 2 MP phone camera.

Im glad you got things sorted out. Pre flowers....A++
Post some of the pics when you get a chance. Has the stretching stopped, well considering it is a sativa probably wont right now.

stretching has stopped since its been back under the mh lamp and i've been doing some research and i heard that flowering with an mh gets quality buds. may add a 2700K 125W envirolight later just to get some denser nugs. since i've been putting it in complete darkness, the preflowers are really starting to grow fast, well imo, this is my first grow so i can make no comparisons. now there are preflowers at the majority of the nodes and still spreading to the lower nodes. will take some pics later in the lighting period and post them up.

nope, this is just my first grow and seeing i'm on a tight budget i thought about giving it a miss. i was formerly going to buy a hps conversion bulb to fit in my ballast as its not interchangeable. but after i found a thread about this stuff i decided to change my mind, here's the link if you're interested.

https://www.rollitup.org/general-marijuana-growing/63422-help-hps-mh-change-over.html

after reading did a little research on google and its possible to flower with the MH lamp. i saw another thread and posted a few questions where someone told me although hps is good for flowering, the mh lamp outdoes the hps as an overall grow that the hps (taking into account vegging and flowering). seeing as i had to start flowering early i won't be getting really big and dense nugs so i thought i might as well flower with the MH taking into consideration all the other factors (budget etc).

I understand your situation. Trial & error is the best way until you can get all of your ducks in a row. Keep us posted on how things go.

ok here's the update, got a bit excited so there's quite a few pics

the far pics are a bit crappy cos i only have a crappy camera phone.

btw the last two pics are of the bottom leaves, they aren't the ones that sprout when the plant is just a seedling as they have already been shed. they are starting to go yellow, is this nute burn or is it natural. i know the lower leaves begin to go yellow and die during flowering, but i thought this was a bit early. i recently added more nutes, i think maybe 2 days ago? they are all purpose nutes and they lie just below the soil surface and dissolve slowly as i water the plants. any advice would be appreciated as i will remove some immediately and maybe do a flush.

help, urgent help required please. i was a complete idiot and forgot to turn my timer on last night. therefore when i woke up (just as the timer should have been going off) i saw the light wasn't on. i turned the light on but the plant has recevied 18hours darkness instead of its usual 12. now seeing as mine is sativa dominant, almost all sativa, i also heard that sativas are more prone to hermies. what can i do to avoid this problem? should i gradually move it back to 6/12 or just put it straight on 6/12? any help much appreciated

Go immediately back to 6/12
