    Oh no, not “defoliation”, pruning.

    As in, Pruning branches so the rest have more space. I don’t really prune leaves that much unless they’re on a branch I’m cutting anyway.

    That being said, if you’ve defoliated twice, then you may have actually overdone it a bit, depending on the strain, as what I’ve found is that a badly timed / too strong defoliation does is it retards the growthspurt meant for buds and instead focuses a bit on “re-leaving”, as in growing new leafs and making the old ones bigger. I might be wrong, but I get that feeling because it looks like it for the general feel. Like you seem to have plenty of light, but there’s still not that many actual bud buds, just sort of a mix between really large sugar leaves and buddish mix. It might be a growth characteristic as well, but oftentimes it is something to do with the growth conditions.

    But… that’s… you’re not getting a lot of penetration through that thicket, I don’t think, so the lower branches will be doing popcorn buds. Even with a 600HPS that would be quite hard. Anyway, pruning is much less to do with light power for me than it is about just getting the plants evenly in the space, but also, very importantly, air flow. We want good airflow among the buds.

    What I do is I let them grow pretty unlimited for a few weeks, while bending the occasional branch this way and other that (one really doesn’t require screens for scrogging, I just supercrop with my thumb and forefinger, gently, without breaking the stem but changing it’s direction). Then some days / a week before starting flowering I prune the lower branches and some of the small side branches depending on how high they reach. Then I end up something like this, although this is a very casual and not well maintained grow I’ve done super-lazily

    The last picture is from early/mid flower. Now I had already harvested about half, I’m still in the middle of harvesting these, so the second last picture from the tent is half harvested, but I think it shows… something. I could’ve utilised the space even better (you filled out yours better than I did this), but, well I hope you see something I’m talking about.

    What’d you think of the purples I got into them? This strain doesn’t produce much purple unless you can get it cold during flowering. Which is nice, because there were just the suitable temps outside for the past month that I could have my window open and have it be like ~13-15C in my growroom at night.

    Anyway, great looking grow, prolly just a way more indica-type growing properties in your strain.

      They have plenty of room.

      Yeah… I’m just gonna bounce from this convo… two defoliations at day 1 and day 21 is pretty standard and there’s plenty of bud sites, you seem to be wanting an argument and I’m not going to oblige. Go back through my post history before making these wild assumptions that are obviously not even close to hitting the mark.

        Don’t be offended for me sharing some tips you may or may not agree with.

        I’ve grown weed for 20 years. You’re 30 days into flower and already it’s way too crowded there. Now I remember the “yeah but more is more, right” mental model, but you’ll only get a tent full of loose bud-like grass with that style. Do you have a RH meter, because I can bet my left nut you’re not even close to 40-50%, which is optimal for flowering. There’s zero room for them to perspire. Even the “buds” you have above the canopy behind there are more than 50% leaves. Look at my pictures. It’s buds. That last picture is from roughly around the same stage you’re in.

        I was just trying to help out a fellow weeder, and ofc I’m not telling you to do anything. Since this hobby isn’t hasn’t been legal for most of the world for a long time, there’s still a lot of “ghetto-science” around it, which is why I feel it’s good to share tips and styles, as you never know what you might learn from another.

        You’re clearly not willing to learn anything though. I’ve known a few growers like that. Usually their stuff was pretty much sugary leaves and some small bits of bud, and tasted horrible (they usually omitted flushing and overfed in flowering, which affects the smoke just… so horribly.)

          It looks like 50% leafs because it has large leafs, which has nothing to do with pruning or defoliation.

          They’re just leggy plants. They grew over 36” from being 6” tall.

          And for what it’s worth, with testing becoming easier and cheaper, people have been testing lower bud sits and canopy bud sites. Lowers test for 20% more THC, which makes sense since light degrades THC, so there’s more evidence to keeping a tighter canopy with penetration.

          Should I have trimmed more, probably, is it doing anything detrimental like you said, nope. Just need to watch for mold.

          I also did more or less worse than this last grow They’re fine.

            because it has large leafs, which has nothing to do with pruning or defoliation.

            But that’s what I’m trying to talk about; I am pretty sure, through my own experience (and all the discussions on forums ofc) on this, that it does. When you defoliate too radically, the plant will try to recompensate, That recompensation will stall new growth of buds and instead focus on building the “energy reserves” in the leaves. This is why the leaves on the buds will start to grow out of proportion, as yours have. That doesn’t always happen, if you can properly manage RH and temp, as the plant won’t be trying to create more leaves to cope. Yours is quite full though, so the RH must be up, so the plant is trying to perspire a lot, as more area is required for perspiration the higher the RH is. So it’s focusing on making bigger leaves.

            Really not the best comparison, but think of what an dog starts looking like when it gets too hot; the tongue lolls out, they pant, go near their face and it’s almost steamy. That’s more or less what those plants are doing. This might also all be solved without changing anything else you’ve done except get a dehumidifier to keep the RH lower if you want to pack it that tight. I still don’t know whether I’m right about the RH issue, maybe you do have dry air and it’s not too high, but I somehow seriously doubt yours is under 70%. Do you have a humidity meter? (I don’t, most times. I get the cheaper ones and then they eventually break, but since I’m pretty accustomed to how I grow with this setup, I don’t really need one to guesttimate accurately enough.)

            If the RH is kept at proper levels, then you introduce more defoliation.

            They’re all fine, more or less. It looks good. Not great, but not bad. I’m not badmouthing you or your grows, I’m trying to give you hints I think might improve your grows, which I think is what all growers aspire to. (Well, except when we get lazy and aspire to see what is the least amount of work for something that is still within acceptable margins. Those margins do get higher though, but I digress).

            Popcorn buds are nice, especially for exctracts. I personally keep them all to myself while selling the prettier top buds. People who buy are after the aesthetic, I just want nice smoke.

            Anyway, no offense meant by any of it.

            I just miss r/druggardening

              I’ve never heard of this before, hydro and aeroponics grow larger leaves due to a variety of reasons, and they create MORE leaves, not larger leaves when you stress them to that degree, but they will also likely herm at that point too. And I didn’t even take off 10% of the canopy, so I don’t know why you would think this could be an overdefoliation, people have taken 50% off and nothing, but 30% is the rule of thumb.

              My humdifier turns off at 50 rh and the fan kicks on when the rh gets over 55. I’ve got 2 fans, one above and below canopy. It is really dry here, usually don’t need to worry about over humidity. I still fill it every day if I feel like it.

              The first image also makes it look darker down there than it is, can I remove more, yes, is it detrimental, no but mold is always a risk, did I remove too much, no. I would love to be able to do more tucking though, pushing the fan leaves down would make a world of difference in appearances I would imagine. From what I’ve seen heard, is when the bracts aren’t swollen is when you should maybe start worrying you’re doing too much.

                I’m sorry but, but your plants are literally wilting in the second picture, which you say went better?

                And just because you’ve never heard of something… it can’t be true? The plants want to perspire. If they can’t, they’ll keep trying. Since your tent is packed that tight, no matter how much they perspire, they’re not actually losing any water, so they desperately make new avenues for “breathing”.

                Plants do breathe you know. You need gas exchange.

                I’m saying it could have been overdefoliation in the case that you’d have pretty much removed all fan leaves. That makes a plant grow in a similar manner.

                But now I’m pretty sure it’s a too high RH with the tightly packed tent. They just can’t really breathe. I’ve not claimed you have it too dry at any point? That’s exactly what my point relies on. Your plants can’t perspire, because they’re constantly in contact with each other. So they create more and more leaves, and no buds. In honesty, it’s a combination of all those things, and all I can do is tell of my experiences and hope they will help you. But you seem a tad confrontational and not that receptive to tips that you can ignore if you want. Like your sort of sly implication that because I’ve grown for 20 years, I wouldn’t be growing hydro? (I have also tested aero on a small grow but too much of a hassle for the benefit to change to my bigger sets) Because I’m some old fart, not “up to date”? I’m a bit over 30 and started with hydroponics, because it’s not a new invention. Been building my own 18 years.

                I’m honestly just trying to troubleshoot a little bit. Unless you think those buds are the best you can do? Because I don’t think so. You seem knowledgeable, but there’s also intuition which comes from just grows and grows and grows, and my intuition is telling me that you have too many plants too close and they have a hard time breathing well. The RH you state seem fine enough, but can you put your hand in the middle of the canopy without it getting wet? Because if not, that’s plants “sweating”, meaning the exact problem I’ve said, be it’s reason RH or not.

                  I’m sorry but, but your plants are literally wilting in the second picture, which you say went better?

                  Wilting? I mangled them trying to get a second trellis on since they were getting too dense for their stems. You’re diagnosing from an image without knowing anything of the scenario.

                  I’m saying I’ve read a lot of grow journals and studies, and that’s nothing that I’ve come across is horticulture either, it’s not rooted in science.

                  And just because you’ve never heard of something… it can’t be true? The plants want to perspire. If they can’t, they’ll keep trying. Since your tent is packed that tight, no matter how much they perspire, they’re not actually losing any water, so they desperately make new avenues for “breathing”.

                  So if the RH is in check, more transpiration means more water use and more nutrient uptake, larger leaves more energy for the plant to absorb. What’s the issue with any of that? You seem to thinking it’s detrimental, why is it? It’s not wasting energy making these leaves. In other cases maybe.

                  You keep saying these have no buds, that could be just as much genetic or pheno differences, but that’s also not that the case here.

                  Trouble shoot what? I started my first message off telling you my school of thought, most of this comes from horticulture and comparative studies, and most people get pissy when science contradicts their anecdotal been doing it for decades. Theres no reason to remove the foliage.

                  Is it the best I can do? Nope, but that’s why we experiment and grow with each one. Could I get some denser looking buds by culling it more, absolutely, but I would rather have 300g of good bud and 200 grams of mediocre higher THC bud than just 400g of good bud.

                  So to someone shooting for the 200g of top shelf, of course mine wouldn’t look as good or as picturesque, but I’ve got far more weed that’ll probably average a higher total THC content, but it won’t look as pretty or dense or large.

                  Edit, I just shoved my hand down on 3 places, now it’s sticky, and no moisture came off. We done here?

                    “We done here”?

                    I’m not arguing with you about anything. I’m pointing out things I notice, and saying things I think. As pointed out, images do not give the whole story. But they do some of it. If you think those are the best buds you can make and you like it, I have absolutely no problem with that. Nor am I saying mine are better. I’m saying there’s always room for improvement for everyone.

                    I’m just noting that it’s very common in the growing community to aim for thick colas instead of loose-leaved branches of sticky material.

                    I was exaggerating a bit with the hand getting actually wet, but there are usually drops of dew on some of the plants, and if you haven’t, well that’s great, innit? I had a friend who was obsessed with pruning though, poor grower — meticulous, but poor — and he waaay over-defoliated his plants (often even because he was looking to dry and smoke some, so reaally really went overboard with it. He had a decent light, but ended getting only bud-like flowers, not proper nugs. Yours are proper, but they have just remind the slightest bit of buds like that, which is why I suggested the defoliation as a cause initially. I may have been mistaken. As I keep saying. I’m not arguing anything. Just telling you my opinions, because I’m not there to know what it looks like there, so perhaps something I say can influence what you perceive, or you can tell me you don’t perceive a thing — as you have, thank you — and it’ll amend my understanding, even though not much, again, because of the limitation of me not knowing much about the grow.

                    That probably means that it’s a very different genotype from what I grow, and that’s totally fine. I know there are a couple of strains that make really airy buds, but to this extent I’ve seen buds similar-ish (but way worse than yours) due to the same sort of growing style. Might be I’m mistaken, might be I’m not.

                    I’m just discussing, not arguing anything. The thing I think could be improved is the size of the colas. Surely you’d rather have a thick canopy of colas then leaves? But, like, again, completely up to you.

                    Hate to trace back so far but to change the subject a bit… you didn’t like the purples on my buds then? (I’m hyped because I rarely get a grow so suitably with this strain I can open my windows and cool the entire room. It’s not a purple strain, just has anthocyanin genetics)

                    Sorry, skipped this bit.

                    Do a bit of your own science? Grow say, some autoflower in the side if you have the room and keep radically defoliating it. Not compeltely bald, but a lot. See how the buds turn out. If you want a control, use same seed on another similar pot next to it, but without any defoliation.

                    And also, yes, it’s definitely based in actual science as well.

                    https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/defoliation

                    The defoliation stress encountered by a forage plant depends on (a) intensity of defoliation; (b) the type of tissue removed, whether meristematic and physiologic age; © frequency of defoliation, whether in discrete well-spaced events or continuous removal; (d) timing of defoliation; and (e) whether stresses or competition have occurred before, during, or after the defoliation (Richards, 1993). Removal of young, photosynthetically active leaves affects the plant more, in terms of photosynthesis, than loss of older, shaded leaves of a lower photosynthetic capacity (Gold and Caldwell, 1989a,b, 1990).

                    Root growth stops quickly after defoliation and fine roots may die (Luo et al., 1995; Jarvis and MacDuff, 1989). Respiration and nutrient uptake also decline quickly after defoliation. These responses, however, may be tempered by the age of the plant and availability of resources. Root growth is also affected by the frequency and severity of defoliation. Alcordo et al. (1991) clipped stargrass (Cynodon nlemfuensis Vanderyst var. nlemfuensis) at several plant and stubble height combinations and observed that root mass accumulation was reduced by up to 97% with severe defoliation compared with an unclipped control.

                    These immediate responses to defoliation are followed by the long-term process of recovering a positive C balance, metabolic adjustment of the remaining organs, and rebuilding the photosynthetic area (Richards, 1993)

                    Those are pretty much exactly the reasons I prune only once and then I only take branches / older leaves and then I give the plant roughly a week to recuperate before putting it into flowering (a source of stress)

                    It’s too long to paste in total but an interesting read well worth it, despite not being strictly about cannabis but defoliation in plants in general.
