45 day strains

[Equipment Junki]

That six hours forty minutes on 12 hours off thing works, but yields will suffer. You can get an "extra" crop (or two) in if you have your shit together.

Problem being you have to plot out on a calandar when the lights are on so you can get into the room. Since you aren't on a 24 hour cycle.

I tried 6 on 12 off and it just did not fit in with my lifestyle. I need to be able to get into the room and do my work at regular times. Lights go on a 7, I can get in there and do what needs to be done and go on to doing something else or chilling.

You can shorten any strains time by cutting the light back to eight hours on. This will also make for more compact flowers and greater bag appeal.

The shortened light cycle has been around for awhile and it never really took off, because for a third less time you are going to get a third less yield.

The schedule is spelled out in this thread. That's when you can get into your room.

Think of the commercial implications for those extra yields at the end of the year, or what you could do in micro applications, eh?

cadillachydro.......Use any 120 timer and a relay to switch your 240

Exactly what I was going to say. I would really like to know if your yield is still respectable after this switch as this is something I would really like to try with my sativa dominant ass kickers. I have 8 600's and 8 tables for them, so I could pull a table down every 8 weeks and they would really be at almost 10?

Very interesting subject!

An old grower I know swears by a 10hrs On 14hrs Off schedule. He's done that for many many years with success. I have doubted his method but with the amazing nutes that are out there, BB, fungi, added sugars, etc. could the plant possibly thrive in this timmming schedule? The only benefit here is a saving in electricity. Has anyone heard of anyone else doing this?

M39 is a fast 45 day good yielding commercial strain, very bushy and close internodes, you can really pack them tight since they just seem to want to grow up and don't spread their branches. They also don't stretch much when you put them into flowering and after 2-3 weeks into flower they have zero stretch, you could go on vacation until harvest and not need to raise the lights. There are many many variances of the strain going arround and I have never heard of anyone starting them from seeds although I know they are available. Has anyone here started M39 from seed?

I have always been interested in trying this

9x52 = 468 light/dark cycles per calendar year
468-365 = 103 extra days light/dark periods per calendar year
103/7 = 14.714 extra weeks of growing time per year
52+14.714 = 66.714 total weeks or growing time per year using 6.4/12 regime

lol kk see if I get this next part right ...

using a 55 day strain as an example.

with both harvested @day 55 of their respective light regime rather than having them harvested at at the end of a week(day 54 of 6.4/12 and day 56 of 12/12) we get..

a 55 day strain taken at day 55 using a 12/12 regime
365/55 = 6.636 harvests a year.
a 55 day strain taken at 55 of a 6.4/12 regime
365/42.779 = 8.532 harvest a year
8.532 - 6.636 = 1.896 Extra harvest a year.

using the end of a week as the harvest for both light regimes gave 56days(8weeks) for the 12/12 and 54days(6 weeks) for the 6.3/12 we get

a 55 day strain(taken at day 56 of 12/12) would take 8 weeks even(56 days)
365/56 = 6.517 harvest a year.
a 55 day strain(taken at day 54 of 6.4/12) would take 6 weeks even(42 days)
365/42 = 8.690 harvests a year.

8.690-6.517 = 2.173 extra harvests a year

If you could truely get a 45 day strain(5 weeks in 6.4/12) you could do 10.4 harvest a year...

I think the 6.4/12 light regime would work well in a many clone to flower SOG..

bump want to hear more opinions on this

 

[wantaknow]

i have done very well with 10 14 off ,no difference in yeald ,as45 day strains ak 48 is very fast and lots of resin ,responds well with 14\10

 

[DangerP]

Is there a good reason you can't reduce the night time as well? Will the plants freak out if you did, say, 7:40 on and 11 hours off? That might help get back some of the yield you might lose on this schedule. Alternatively, you could further shorten the days.

 

[Guest]

Should not go less than 12. I just don't understand the point. I am always looking for ways to get the most LIGHT. Maybe going 12 off and then 15 on. Extending the flowering time to see if you can increase yeild?

Has anyone tried or thought about that??

B u m p

Great post.

 

[tngreen]

i like the way you think cannaboost! very interested in an answer to that.

hi

hi

depending on what high you re looking for but i believe northern light would do the trick and as a first experience it ll be a very forgiving strain .(real fast flowering plant and real good yielder.you can add a costless home made co2 supplier . if you need some info about this one let me know)

someting else; i do not understand the 6.40 hmn on .
i know about 6/12 on and off cycle but why 6.40/12

how does it help and what difference does it make?

 

[seaofvert]

cannaboost.

it s no need to let them have more than 6 or 12 hours of light (depending on the cycle you r using) because the plants in blooming stage do not light feed all the time and it s been proven that 6 hours of light per "day" is actually enought .
you wouldn t then make flowering longer or better increasing the light hours to 15 in the growroom.
on the other hand the 12 hours of dark in the room are really needed. the only drowback about the 18 hours day is that the maintenance get a little more tricky since each day in the growroom starts at a different time (i did it myself and unless you re running a hydro system with water suppliance for at least 5 days,wich i didn t at the time , it s not worth the harassment
i ll try to find a link how could explain this to you in better ways with a better english and get back to you.

 

[Guest]

I was just making a point. I think that light is a good thing. In theory, if we were extend the light cycle to 15 on and 12 off we would be extending the flowering time because "days" would be 27 hours long.

As I regress I agree, a simple 12 on 12 off is the way to go! .....IMO

 

[seaofvert]

in theory. hummm.

knowing that a plant in the blooming stage mostly put her energy in flower formation wich occurs at night time i really wouldn t think that longer day cycle (over 12 hours) would make a difference .

then again it s just a though and since i ve never did the experience i wouldn t know so cannaboost i suggest you to try this and let us know what difference it makes.

i know this thread is old, and had recently gained my attention.. just wanted to say that this guy is a dumb dumb.

10 hours on and 14 hours off is still 24 hours. the guys wayy earlier were talking about 6 hours 40 minutes on and 12 hours off. 16 hour 40 minutes total. no wonder you had no difference in yield...

just had to make this comment... this thread IS history (which is studied... i was taught in highschool that history is taught in school because it is the best way to learn ) ISNT it?

on that note... time to switch to that schedule! wouldn't mind saving some energy money also!

They are still using a 24 hour schedule with this setup. It's just that 1 week is really about 9 days. In most cases the 6 hr 40 minute schedule yielded a little less but allows for more harvest per year and also randomizes your light schedule a little more for the power companies to try and track it.

 

[Sepro]

i would like to see an actual controlled comparison. this is indeed very interesting. i think i might give this a try. its funny how nobody posted any results though.

 

[BlindDate]

It's really simple. A 6:40/12 schedule is 22% less time. So as long as yield is not reduced by more than 22% you'll come out ahead assuming zero veg time.

The longer you veg, the less the percentage becomes since the total time is diluted.

As an example, if you veg for 2 weeks the percentage comes down to 18%

Did anyone on this thread ever find a timer with 18 on/off settings? I guess that you could use an interval timer or 2 regular timers to do it. I have one of those 14 settings per day timers, but they don't seem to work the way that they imply. It doesn't allow you to set up each day for 14 settings seperately. It lets you set 14 time schedules that can occur on a fixed 7 day setting.
