    I'm far from the average bear my friend.
    Please point out each and every mistake. Not gonna lie or exaggerate I medicate often and mistakes happen.
    Some of the screws are coming loose too but I'm always interested in learning :bigjoint:

    Okay so what happened? Somebody let the thread get ridiculously long and now it's hopeless trying to find anything. People can start a "part 2" thread you know, like after about 30 pages. Anyway, so wtf happened when you used 8 hour photoperiod, reduced yields?

    Welcome back
    Subtle bob
    I'm saddened to hear about your displeasure in my grow journal length. I didn't think about how this decision would effect others please accept my apology.
    Still not going to start a new grow journal tho. I'm actually pretty sure you were just in my journal a month and a half ago asking the same questions.

    During previous runs in my cabinet and at other rooms I have I've gotten it up to 80-90% of my old yields. This current run under the quantum boards looks like it might end up my highest g per watt but I won't know for another month at least.

    Lol, Bob's off his meds again and trolling other's threads, weird ;) Funny how much he has to say for someone who has yet to post anything resembling a coherent grow.

    Doesn't bother me in the least.
    Theres already more then enough negativity in the world without me adding any to it.
    I'm not on here to bash or bad mouth anyone. Bob and anyone else wants to ask questions is more then welcome.
    I think he was under the impression that I was doing a side by side comparison or something similar.

    I'm sure it's frustrating to find out it's just a grow journal.
    That's ok life makes a flavour for everyone

    Oh, was that you I asked for a summary a while ago? I thought that was a 6 hour thread. Anyway apology accepted. Didn't actually notice this was in the grow journal forum. Seems more like an "advanced mj cultivation" thread. Thanks for the new summary, if that was you before. Seriously though, some of these threads are way too long for practicality.

    Oh sure, I'm gonna write down a record of a grow in a special format, for what purpose? Ain't nobody paying me to go to all that trouble. I start clones, I grow them out, I harvest them, end of grow journal. It's the same every time.

    After reading this thread I can't help but ask why a light over lap system is not the best of both worlds?, should this 6 or 8 hours light on venture be worth while.

    If you currently use two lights, light 1 comes on for 6 hours. At 6 hours the next light turns on, the first light stays on for another hour or so (kind like mid day) and then shuts off while light 2 stays on for the remainder 12 hour period. If you have three lights then do it in 4 hour segments with 30min over laps. 4 lights, 2 hour segments with 15 min over laps. Or with 4 lights just have two lights on for 6, two lights off, similar to the first example.

    You half the electric bill and ''if'' the more shaded side of the room don't create more stretch as a result, you would be better off than having all lights on 6 off 18. Maybe.

    I only suggest this because perhaps light saturation/wasted with all lights blazing is possible?. With a lower more constant light over the full 12 hours maybe it's a better result. Or again, maybe it just creates stretch.

    It would be a interesting concept for the hot summer nights. The reduction in light/ac cost (and I assume nutrient ec level reduction) may more than off set the lower yield. But then perhaps RH rises?.

    The 3 room thing also sounds interesting RM. But would that not force you into midnight or early morning feeding/maintenance for one of the rooms?. You'd also be spreading the load over the day/night for the other two rooms. That sounds like it would get in the way of life quite often.

    I believe @ttystikk may be trying something similar to this eventually.

    At the start of this thread I tried 6/18
    But the buds failed to put on any sort of swell whatsoever.
    That was back when I was using a 400mh. So I think it's safe to say the plants weren't getting "too much" light yet. Now that I've added 2 hours and ran 8/16 for awhile I'm confident I can produce enough yield to keep myself medicated.
    I'm sure that the new led has helped tremendously in bringing the yield into the usual yield ballpark.

    For myself long term I think the best set up will probably be three led lights over three seperate grows all being powered by one driver on a switch that triggers each one every 8hrs. Using this method the grams per watt would be pretty good imo.

    Either way @Flowki
    I forgot to say thanks for stopping by and I'm just glad that more n more people are thinking outside the norm or accepted 12/12.
    I'm blown away by how many views and comments my journal has received.
    Feel a lot less crazy these days now that it's not just me

    You need to defoliate those bitches a little bit , Do it right and you'll gain a little yield ....

    So for everyone just tuning in , what L/D Schedule are you using ?

    Well that sure looks like 8/16 is working very well. I have to flip my soon due to a space shortage, and for sure I am going to try this.

    I'm not sure what kind of light you are using so I can't offer much of an opinion as to how u should run your light.
    I want to be as honest as possible always so please remember that the 8/16 theory or any shortened cycle is that the plants get "too much" light while it's on.
    These plants I'm running now are
    At least twice the size of the ones I had last run under the 400mh. To me that's a drastic lighting difference.

    8/16 will still grow you nice buds but there is a yield loss %
    Now what that will be for you specifically I can't say

    zoic Well-Known Member

    I was thinking about that also. I am only running a 2lights x4ft LED's that are 38W and 3700 lumen. One idea I considered was 12/12 for 2 weeks and then down two 11/3, 10/4 and if that goes well I may try the 8/16. I am going to play it by ear until I can invest in a better setup. So yield wise I think I will be happy to just get anything. :mrgreen:

    I think what he's trying to say is that if you try a shortened day schedule, you'll get better results if you don't skimp on light intensity.
