    Darkness before the harvest

    Do any of you folks go with 24 -48 hours of dark before harvesting? I did some comparisons between no dark time, 24, 48 & 72 hours and I didnt notice any difference. I have also heard its best to harvest before the light come on I usually do that but more becasue I leave the lights out for 24 or so hours so I can harvest when I want to. Just not a morning person

    I swear I remember Nebula doing a piece about that but I can't find it.
    If I remember correctly, the extended dark before harvest is bro science.

      Maybe not bro science. Found the article.
      Does a 3-Day Dark Period Before Harvest Increase THC? | Grow Weed Easy

        There is a lot of info out there on the subject and I did a similar uncontrolled test between no dark period, 24 hours, 46 hours and 76 and there was no noticable difference but I didnt send it out for testing, I use my wife as my Guinea pig. So assuming these tests were done on the same plants I have to wonder did it prove the lights out time matters or stressing the plant by cutting off some buds before harvest boost the the THC?

      I turn my lights out at final harvest just to save electricity on lighting and cooling costs. I'm not sure it does anything but that.

      Edit. It takes me & Mrs Bluey at least two to four days to harvest a full grow in the flower room as I wet trim the good stuff. The fluffy crap doesn't get trimmed because it makes for great extracts.

        I've been using this procedure a while now. It seems to lower the smell of chlorophyll after 24 hours. I stop watering and when the pot seems to be getting light, I wet trim and use a dark period (24-36 hrs) the n I harvest. Drying time is cut in half. Jar it and burp for 30 days and smoke that shit I would. When you pull the pin on a grenade don't throw it away, throw the grenade.

        I believe that this common practice has been debunked at this point. I’ve heard Dr. Bugbee discuss it. If there is no light the plant is not photosynthesizing so not creating secondary metabolites. He suggested lights on for 48 hours before harvest would be a more science backed approach.
        I did it for most of my first 10 or so grows, but I don’t do it anymore. You could argue other reasons to do it I guess , but sounds like more trichomes isn’t one of them.

        It’s a very established approach that lots of folks believe in. I even heard Dr Coco from cocoforcanabis.com say as a scientist he thinks it’s debunked but he still does it, ‘cause we don’t know everything.
        Listen to this clip to hear it discussed and explained better than I can

          Not to put myself on their level but I dont think matters but I also dont think it hurts either. I am not sure how you could do a controlled experiment either. If you use the same plant how would you know if the sress didnt boost the THC or its becasue the roots had less to feed after the first buds are cut or if waiting a couple more days boosted it? So I am going with Bro Science

        Read the article I posted Allenpro. It's short and has pretty pictures. In the end, more research is called for.
        One of my questions is how much effort is a person willing to put out for an extra X%? Another one of my questions is, how much of a percent change does a person need to say one bit of dope is stronger than another bit of dope?

          We dont need stronger cannabis so why bother?

          The strong stuff is already wickedly strong and where I'm from the most popular weed for smoking is old skool sativas around the 8% to 10% mark.

          Do we really need to make the 24% stuff 26%?

              Dab, you fool! Dab! At least get yourself a quality pen if you want higher percentages. My norm is above 70% but I still get heady from 20%.

              See if a dispensary near you has any 400mg Each gummies. My wife went into a dispensary in Maine and asked for the strongest gummies they had. She wont do that again. She got 10 (4000 mg) made by a local company called Baked Bliss, popped her usual 2 and I had to carry her to bed and she is a regular smoker. I took one and ended up stuck it the chair for 4 hours. Now we just take a very small peice and chill. A half of one is a garenteed weed hang over the next day

              There are all sorts of pens you can get for dabbing. Not vape pens. Pens that you screw coils into. Super portable. But for simplicity, vape pens are the best discrete portable inhalers.

            ductwizard I dab what is dabbable. That is, pretty much anything that has been dewaxed. DIY BHO is probably illegal where you are and is so extremely dangerous that I recommend no one but Satan make it.
            That being said, there are all sorts of videos on how to make BHO at various levels of quality from shatter to live resin. Then there's rosin that is made from heat pressed kief. I don't get into that because of the equipment. The most basic way to go us using a glass extraction tube, or as I like to call it, a glass dick. Google the tube to see what I'm talking about.
            A method I have just started working starts in post 90 on page 7, a better breakdown of the process on page 9.

              BHO is dangerous and illegal.
              Check the link. That process is only negligibly dangerous, mitigated with a fan, and perfectly legal.

            This is exactly the problem when trying to manage tolerance levels and chronic pain and the risks of chronic exposure. Increasing levels of THC % exacerbates the problem with tolerance and it's still happening today with opioids, which leads to death, but to a lesser extent since the acceptance of medicinal cannabis across most of North America. Chronic exposure to cannabis does have its serious health problems and DabberDog has touched on that. Other methods of management for chronic pain need to be used to deal with the issue of ever increasing tolerance and this is one for your health professional, not me, to manage.

            Skunk weed grown here has the highest levels of THC that I think I've ever tried and this has had me hallucinating something terribly along with serious anxiety to a dangerous level of panic attacks, which is the only time in my life I have ever experienced that and it's not a road I will ever go down again. So the super strong stuff is particularly dangerous for me given the above and I'm sure I'm not alone.

            Then like so many do, add a bit of alcohol into the mix and we have a total disaster in the making. I'm sure most of us have seen it if not experienced it ourselves.

              i recently had all my toes amputated and lost both my heels to gangrene, i went from morphine 6x a day and a fentanale patch to tylenol. needless to say it don't work. i went to a pain management doc. and he told me they can't give more opiods due to legislation? he gave me breathing exercises like a pregnant chick. try breathing like a preg. chick 24 hours a day. the doc also said this is why so many ppl. turn to herion. i would not do that but i would smoke 100% thc weed

                Vape pens are generally over 90%.
                THC-A diamonds are 99.9% but can make a strong man paranoid. That is the most potent product you can get.
                I don't know the legislation of it. A responsible doctor prescribes opioids for acute pain, not chronic.
                In my past... a treatment I heard for amputee pain (phantom limb syndrome) is to have the person look at the site of amputation in a mirror. It's about seeing there is nothing there to hurt. Sorry if that's personal.

              Blueydog, buddy. This is not directed at you. It is directed at the idea of people using marijuana for medicine. There are exceptions, as most dope smokers claim to be, but in general, the following.
              A 30-year-old who began smoking weed when they were a teenager did not begin smoking to get rid of a backache. They did not start smoking for the placebic or actual medicinal value of it. It was to get fucked up.
              A 30-year-old who torks his knee, researches the myriads of choices of pain relief and settles on weed is trying weed for medicine. But...
              Accurate dosing with flower is impossible. Have I ever used the "I" word? Not sure. Every bud is different. There may be an average over the whole plant, but to say, "Imma gonna use me 1.4 grams of bud for .X-grams of THC, .Y-grams of CBG, and .Z-grams of CBD." just ain't hap-nin. You use until you get the affects you want, yeah? What medicine is dosed as, 'Take until you feel better, but don't take too much or you'll freak out.'? You have the one-hit-wonders and you have the tried-and-true border weed.
              And smoking a medicine? Huh? I'll eat my hat when someone convinces me the benefits of the canna-'s in weed outweigh the physical damage from smoke or vapor. We used to think tobacco and alcohol were medicines, too. How's that turning out? If we call something that has great potential for damage a medicine, we use that as a shield. I had a girlfriend who tried to convince me weed was bad because it was making my lungs black. But her doing meth was okay because it kept her from getting fat.
              Me? I smoke dope because I like myself and the world better when I'm high. It's just a better place for me to be.
              Before I get hammered by a bunch of people telling me I don't know what I'm talking about: first paragraph above, fourth sentence.

                Completely agree re smoking/vaping re dosing, but it still has medicinal value in a whole range of areas even so.

                I've used it the first 25 years of my life simply to feel good and used it with my partner for intimate purposes. Last 10 years I've also used it to sleep and without it at times of pain it was impossible.to sleep, different types of pain at different times. I've also used it just to get rid of pain and its worked quite well for me for that too. My pain is not chronic yet but one my medical condition is.

                I know it works differently for everybody as what works for you may not work for me and it may well be I have a low tolerance to it as I have always suspected and I've maintained that low tolerance somehow so it stands to reason then that some will need quite high doses compared to my wimpy doses.

                What does concern me is the too gooders that want to wind us back to the times of total prohibition and they are still trying to find any bullshit to do so. Chronic exposure is one of their excuses.

                Another side of this is cannabis cannot be abused or misused because no one has figured any of this shit out. Dosing, I mean. How much canna- do you need to... 100lb body vs 200lb body. Half life. The only way you can abuse or misuse something is by using it for other than intended purposes.
