Complete scrog/sog walkthrough

[decept1con]

OK so i have found tonz of info on rollitup about scrog/sog. Its been fun and motivating piecing the info together and making it out in my mind. Here is a post i found with great pictures and info. I hope it helps anyone looking for info on this/these methodz....All credit for the info goes to Quazi from International Cannagraphic. An Overview of Cannabis Training (ScrOG, SoG, FIM, Supercrop, LST, etc.) Now then. After the reactions that I received on my first dive into guides for training, I thought a more complete guide was necessary as it's something I've done quite a bit more reading into since then and I've also gained experience and insight into various methods. In addition, it seems the same questions are still being asked by newer growers. There are a lot of good sources of information out there on the subject. However, I felt a compilation giving a brief explanation of them, with some examples, would allow everyone to develop a common language here. In addition, it'll help those newer to the hobby, and the forums, so they can understand just what the hell people are saying. This guide will be divided into five parts: I) Understanding Training II) High Stress Training Techniques III) Low Stress Training Techniques IV) Sea of Green (SoG) V) References/Links No better place to start than the beginning... Part I: Understanding Training First, I should go over the acronyms just to get them straight so that we all know we're talking about the same things here: -ScrOG - Screen Of Green -SoG - Sea Of Green -FIM - Fuck I Missed -LST - Low Stress Training -HST - High Stress Training With that out of the way, let's go into a small explanation as to why these methods are used and what they can help you achieve with your plants. We'll start by dispelling a few of the most prevalent myths about training: 1) Training can take place during flower. 2) Training is not just to control the height of the plant. 3) Training can be done for any strain. Though some react better than others. With those three things out of the way, let's get into some meat and potatoes. Training can be divided into two main categories: High Stress Training - HST Low Stress Training - LST (also a common name for a method of training so be careful with this) The two types of training are like they sound: either more or less stressful for the plant that you are training. For the purpose of this guide and according to most of the sources out there, the differentiation is simple: LST = not physically damaging the plant HST = physically damaging the plant Notice that I did not say harming the plant because, well, it's training; none of us are out to hurt our plants. Both of these types of training produce similar results, but they are done in different ways. Everyone who trains has their preferred method. To help you pick the method that you'd like to choose for your grow, I'll explore the pros and cons of each. We'll go into detail about the different types of training in the next parts of this guide. High Stress Training -Pros 1. Quick 2. Easy 3. Requires no additional parts (except to cause damage) 4. Great for larger grows -Cons 1. Creating possible sites for infection 2. Can backfire if the plant reacts poorly 3. Mostly irreversible 4. Mistakes are more costly 5. Possibly slower recovery time Low Stress Training -Pros 1. Does not stress plants as much 2. Reversible (for the most part) 3. Forgivable 4. Great for micro grows 5. Fun to do as it's more involved -Cons 1. Requires additional parts 2. Takes more time 3. Possibly less fun to do as it's more involved (just depends on you) 4. Requires more plant manhandling Training, when executed properly, has great results that can be seen in both quality and yield for your plants. It can be the difference between 2 big colas and some popcorn to 8-10 large colas: Training, whether it be HST or LST, is done for the same reason: to reduce the level of auxins in the tip of the plant. Cannabis is a plant that grows with a characteristic called "apical dominance." This means that, like other plants, it will do everything it can to push a single tip towards the source of light. We call the tip of a plant that grows like this the apical tip or the terminal tip. The tips of the cannabis plants are also where the biggest colas are produced due to their proximity to the source of light. The tip of the plant is also where a particular type of auxin (plant horomone) is most prevalent. It's called indole-3-acetic-acid (IAA). Unfortunately, due to the chemical properties of IAA, you won't see it in the rooting horomones you can buy. More than likely, you'll find indole-3-butyric-acid (IBA) and/or a-Naphthalene acetic acid (NAA); other auxins. Now, the auxins promote growth when they are in certain levels but they can also inhibit, or stunt, the growth of certain aspects of the plants if they are at higher levels. This is the case for cannabis plants. The plant is perfectly happy pushing one bud up as far as it can to the source of light. The other buds, lower down the branch, will remain auxiliary buds and branching is not as likely to occur in these places. This is especially true in smaller, indoor environments. This is because the auxin production within the apical tip is very high, preventing the lower buds from growing out. A very obvious example of this is in nature with the pine trees: So, training, whether HST or LST, is done to accomplish one of two things: 1) Removing/inhibiting the main source of auxins 2) Making the plant think the apical tip is no longer the best source of light By removing the main source of auxins, the lower (auxiliary) buds are no longer inhbited. The plant will now concentrate on the auxiliary buds and cause branching to occur in order to get itself a new apical tip. In ideal environments, the plant will grow somewhat symmetrically so that means you can very often more than double the number of growing tips. By making the plant think it's apical tip is no longer the best source of light, it will send the message (via auxins and other chemicals) to the auxiliary buds lower down the stem that they need to grow up to get to the light. The tip is not removed, but new bud sites are formed further down the stem. Depending on the length of the stem and strain of the plant, you can sometimes get many, many bud-sites to grow this way. In either case, you end up with more bud-sites closer to your light source than before and, most of the time, you'll end up with a more even, bushier canopy to ensure your lights are being utilized to their fullest. Now that you've got an understanding of training, we can start to look at some examples. Part II continues below...

Part II - High Stress Training Super-cropping, topping, chopping, decapitating, crushing the herd, bending the stem, FIM, call it what you will: it's high stress training (HST). Any time you are physically damaging the plant to train it, you are causing it to undergo a series of chemical and horomonal changes that will result in what everyone is looking for: more budsites on your plant. There are 2 main types of high stress training: 1) Topping (via FIM or other method) 2) Stem mutilation We'll start with topping. Topping involves removing the apical tip from the plant. This causes the plant undergoe a series of changes, resulting in the auxilary buds sprouting new apical tips. As discussed in part I, this is because there is no auxin generator above the tips inhibiting the growth of the sites. This will usually result in at least two bud-sites where there was one. Another type of topping is called the FIM method. FIM stands for "Fuck I Missed." This is because, instead of completely removing the apical tip, you are only removing half of it, looking like you "missed" the top. This can results in 3, 4 or even more tops from the location. A common FIM technique, is to bend a box-razor blade so there is a curve in it. This way, you can scoop out the area necessary to make the FIM cut. DierWolf, from the grasscity.com forums, produced an excellent image that illustrates the difference between regular topping, and the FIM technique: So, you might be asking yourself: "if the FIM technique produces more bud sites than regular topping, why would anyone top their plants?" Now would be a good time to look at the pros and cons of FIM vs Topping. FIM -Pros 1. Potential to produce many bud-sites 2. More careful methods 3. Can keep canopy level the same 4. Great for small grows -Cons 1. Large risk of failure - if you cut wrong, you won't get the results you're looking for 2. Larger risk of infection - more exposed foliage 3. More time consuming 4. More difficult Topping -Pros 1. Quick 2. Easy 3. Does not require tools 4. Great for large grows -Cons 1. Less budsite potential than the FIM technique 2. Longer recovery time FIM is generally known to cause more bud-sites than regular topping but it is definitely more time-intensive. Topping can be as simple as using your fingernails to pop the top off of your plants as you walk along your grow. To properly FIM, precision and a tool must be used for maximum results. Speaking of fingernails, let's look at the other type of high stress training: stem mutilation. Now, there are interesting theories, methods and discussions invovling both the science and application of this type of training. This type of training is known by many different names: -Crushing the herd -Supercropping -Stem-smashing -Leaning the stem over All of them have the same general idea: mutilate the stem evenly around an area so that the stem bends over at a 90 degree angle. In this case, we aren't removing a piece of the plant, but rather damaging an area of the plant so that the angle of the branch changes. The most common methodology for crushing the stem is to pinch the stem enough that it breaks and separates a bit. Then, turn your pinch by 90 degrees and pinch again. This will cause the tip of the plant to fall over at an angle. Supercropping can be done during vegetative growth to achieve effects similar to LST. That is: the apical tip will be bent downwards once the branch has been pinched. This causes the plant to think that it needs to send new tips to grow towards the light source. Supercropping can also be done during flower to keep those stretchy plants from burning themselves. There are plenty of examples of supercropping well into flower w/out having too adverse of an effect on the plant: pic Obviously, some strains will respond better than others. In addition, if you supercrop well into flower and you have some heavy budsites, you may find the stem has troubles supporting itself. Be smart about it and don't crush the stems too hard if you don't think the plant will grow out of it. Let's check the pros and cons of this type of training: -Pros 1. Not as stressful as removing plant parts 2. Less worry of failure 3. Not as prone to infection 4. Quick and easy -Cons 1. Somewhat inprecise 2. Can have a learning curve 3. Changes for different strains In the last type of training, I started to talk about how supercropping can be used to trick the plant by damaging the stem and causing the tip to fall to, or below, a horizontal level. This leads us into the basics for the next type of training. Part III continues below...

Part III - Low Stress Training It is easy to get confused about low stress training when you are first exploring cannabis training. This is because the acronym for low stress training (LST) also happens to be the name coined for a particular type of low stress training. No one is quite sure of the source, but many attribute it back to Delta or myMUSICveins (thanks greenisgold) for popularizing the name and the technique. There are two main types of low stress training: 1) The tie-down method 2) Screen of Green (ScrOG) Low stress training does not require any mutilation or damage to the plant which, for some, is the sole reason to use it above high stress training methods. Low stress training is done by tricking the plant into thinking the apical tips are no longer able to be the apical tips. In nature, if a branch gets blocked by another branch, or a large leaf from another tree, the plant will do it's best to navigate the growing tip so that it can continue growing upwards. If, however, the plant cannot easily find a way to make that growing tip go back towards the light, the level of auxins will shift, and the lower sites will be called upon to try and stretch up to become the next apical tip. This process can be repeated over, and over again in our controlled, indoor environments: apical tip grows up, apical tip trained down, other tips grow up, other tips tied down, more tips up, and so on. Now, let's look at the two approaches to low stress training. First we'll explore the tie-down method that is also just known as LST. There are a couple different approaches to LST. a) Constantly training a single apical tip b) Training every apical tip The first approach involves constantly training, and untraining, the main apical tip so as to utilize as much of the growing pot as possible. TillthedayiDIE420 from rollitup has a great image detailing this method: In the image, the 1st large number represents the week. The second large number represents the size of the pot in inches. Although it does not need to be followed exactly, the idea is there. The second approach to LST. Its simple, train every apical tip down until you are happy with the bush you have. There are many different ways to attach the training to the pot and the plant. In addition, there are many materials that you can use to apply the training. I prefer using clipped pieces of shielded copper wiring. This reduces the amount of time you have to fuss with knots and the pieces are easily reusable. For attaching, you can attach the tip to the base of the stem to begin with. From there, you can either put holes in your containers, or tie some rubberbands around the outside and pull the training medium down to them. They just snap in place. Very handy and easy, though the rubberbands have to be replaced: Now that we've gone over LST, we can look at the Screen Of Green method. The ScrOG method is almost identical to the LST method. Instead of using string or wire, a screen is fastened to the pot, buried along the edges of the pot and stretched up across the plant, or built separately from the plant. Once the plant has reached suitable height, training can begin. Once the screen is above the plant and the apical tip is long enough, it is bent down and pushed beneath the screen. This will cause the tip to grow horizontally. In addition, it will promote new tips further down the stem. These tips can then be trained downwards for horizontal growth, or trained to grow upwards in the hole of your choosing after some horizontal growth. Eventually, the main tip will find it's way to a hole in the screen and start to grow up again. Depending on the size of your screen, you can push it back down and under to promote more growth further down the stem, or allow it to continue upwards with the new tips that you have created. ScrOGs can be done for single plants, 2-3 plants or multiple plants in a SoG-style setup. Once you have a nice screen of tips, or a jungle of trainings from string/wiring, you can send the plant into flower and watch the magic happen. Now that we've looked at the different types of LST, let's look at the pros and cons of each. LST (Tie-down method) -Pros 1. Requires very little materials 2. Can be moved from pot to pot relatively easily 3. Easy -Cons 1. Time consuming (especially if using string) 2. Materials may be harder to reuse 3. Harder for larger applications Screen Of Green (ScrOG) -Pros 1. Easy to train once setup 2. Screens can be easily reused 3. Can be done for large applications w/out requiring much time 4. Cool as hell to look at 5. Easy to harvest -Cons 1. Requires setup 2. Hard to transport or move from pot to pot 3. Requires a bit more learning 4. Requires planning ahead of time for best results Since both methods are so similar, it really ends up coming down to a matter of style and preference more than anything. Both produce excellent results and can greatly increase your harvest. This is especially true for micro-growers where every bud-site counts. Speaking of every bud-site counting, we're going to explore the last bit of "training" for this guide. I put quotations because, well, it's not really a type of "training" at all. Follow along and you'll see what I'm talking about. Part IV continues below...

Part IV - Sea of Green (SoG) The Sea of Green (SoG) is not really a training method, persay. However, because the acronym often gets lumped within micro-growing styles, I felt it was worth exploring in this guide. The Sea of Green method does not involve training the plants or changing levels of auxins like what we've talked about before. Instead, SoG allows a grower to maximize a variety of cannabis while at the same time trying to dial in a strain/method that allows for the most grams per watt. The SoG method involves growing many plants in smaller pots. Usually this is done with clones. There are quite a few different growers who utilize the SoG method in these forums. SoG can be done on smaller scales in containers such as cut 20oz soda bottles, or it can be done by utilizing taller, 1/2-3 gallon containers, with less width. By allowing for more plants under the light, one can grow many different strains without worrying about the canopies interfering with each other as much. The idea behind smaller SoG grows is to get bud from the soil to the tip of the plant. This is a strain-dependent characteristic, but is often a desired one from SoG growers. Let's take a look at the pros and cons of this method. -Pros 1. Easier to grow more strains 2. Clone friendly 3. Can potentially mean increased yield -Cons 1. Higher plant count 2. Not good for all strains 3. More time-consuming SoG is great for some who want variety and a bunch of colas sitting in their flowering chamber. However, the small size and number of plants is just too troublesome for some. Now that we've looked at the main types of training, you can make your own decision and go out there and start maximizing your yield.

Thank you so fucking much man

Brilliant Update Bro! Always wondered about the finer details on this type of growing and now I understand what the hell is going on! One can understand why these methods where implemented and being used today. Thanks for the update!


BTW - Does anybody know what means would be the best to increase yield for Sativa's in general? I do know that Sativa's don't do well with this type of growing means, but are there techniques that do work for Sativa's or is topping the safest way to go? Input appreciated!

[psychoholic22]

Very cool man thanks for the info!!!

 

[mr.lightgr3en]

First I'd like to say thank you for taking the time to set it down for us noobs and understanding the differences on all this different methods of growing!!
Now this is what you wrote:
(By making the plant think it's apical tip is no longer the best source of light, it will send the message (via auxins and other chemicals) to the auxiliary buds lower down the stem that they need to grow up to get to the light. The tip is not removed, but new bud sites are formed further down the stem. Depending on the length of the stem and strain of the plant, you can sometimes get many, many bud-sites to grow this way.)

I just want to make sure I understood this correctly. If I cut the tip off it, it will encourage more growth at the bottom of my plant meaning more bud sites.
But what if I don't do any topping or fimming. But (lst) the plants stem all around my round pot meaning stem is absolutely tied down laying on the pots rim. Distributing even light to the stem for more under growth. Will it still give me and equal amount of but sights?
Or do I have to cut off the tip of my plant for it to concentrate on having another apical tip?

I have a plant that im lsting in a micro grow so far I have tied down the stem around my pot halfway and switched to flower 1wk ago but I did not top so it still has its main apical tip. Should I top or fim during flower or just leave it alone.

Thanks for your help great thread. =D
