    24 or not.

    So is it worth the extra cost to run 24/0 in veg or does 18/6 do it? This is a simple question but does anybody truly know?

    Well first are you talking photos or autos? And ask @dangerdan

      Sorry man, photos in vegatative. Seems like an easy way to save 25% on the electric bill if the gain isn't 25% on the veg side for the additional 6 hours.

        With photos it is not really worth the extra cost from my experience and from what I have read. Yes they grow faster but not enough to account for the cost.

            I didn't know you had another alias DrPhoton. 😕

          I did 24/0 for first three weeks of the plants life, then switched to 18/6 but these were photos, and honestly like others say such as Redwasp and DrPhoton, I can’t see the advantage for the amount of energy given, so I’d save on the power. Just my thoughts.

            I agree with NG. I don't see much of a advantage except a bigger light bill. Besides, it doesn't seem natural. 18/6 for me.

              I've always considered 24 hours of light too much light, even for autos. Plants, just like us, need a little break. 24 hours of pure, uninterrupted light just seems unnecessary and a bit stressful for the plants. Not to mention on your wallet. I understand some growers do just that with good results. Still, IMO, it just seems too harsh for me to try on my plants. So yea, I agree with the rest of the posters here; 18/6 all the way for your photos.

                You have to channel KFC's methodology, using modified genetics they can grow a chicken from egg to table inside of 6 weeks. I equate this to be the same with Auto plants.

                I only raise laying hens but did look into meat birds and if you let them go past 8 weeks of age they usually die from heart attacks or break their own legs from the fast weight they put on.

              Well, I'm gonna be the only dissenter here, not because I know anything about growing but rather that I read it on the internet. Here is a blurb from my Sour60auto seed supplier;

              "Indoors, with a light regiment of 18/6, or 12/12, she will do fantastic, but she excels under 24 hours of constant light"

              My seedlings have been under 24/0 for the last 14 days and will continue that until harvest and use it as a comparison for my next batch which will be done at 18/6.
              For my 2 lights (200watt total), the difference between running 24 vs 18 is only $3.60 a month.
              Sour60 autos.

              Completely agree here, I have my plants on a 6/2 veg cycle three times a day to help encourage root development, check out my current perpetual grow
              Grow and good luck

                Just checked it out. Nice work! 6/2 veg cycle 3x a day. Interesting. Haven't tried a schedule like that before.

              I say that the extra electricity you use, does not pay for itself in final product.
              completed 7 grows
              what I have learned so far:
              environment maters more than nutrients
              at least a dab of nutrients in every watering
              effective flushing before harvest is critical to quality

                Anything over 17.5 hours a day, is not cost effective for the yield gains and the increased risk of stressing the plant.
                That said, cannabis does not need a break from the light cycle which is why 24hrs works for so many.

                I take a middle of the road approach and start my seeds @ 24hrs of lights (mostly for wamth) until the 4-5 node and then reduce it to 20/4 through flower for auto's. (photo's flower @ 12/12).

                Many seed companies will suggest 14-18 hours of light (auto's included) reducing the stress factor, too much light/heat may cause.

                Any adjustments to my light schedule- has more to do with controling the enviroment- which in turn will provide a better grow overall.
                It's all bullshit - until you smoke it!
