Guide To Cannabis Plant Training Part 1

    How to Train Indoor Plants for Bigger Yields:
    Are you interesting in increasing your yields when growing indoors? Plant training is one of the easiest ways to increase your cannabis yields without having to upgrade your light or setup. It can be used to increase your yields up to 40% compared to not training, and it's free!

    First off, what is plant training?
    "Plant training" means physically manipulating the plant so it grows more bud sites, resulting in increased yields indoors.
    Why not let plants grow naturally? Cannabis naturally grows in a "Christmas Tree" shape that is optimized for sunlight, not grow lights. Unlike the sun, cannabis grow lights do not rise and set every day, providing light from the sides. Furthermore, indoor grow lights have almost no penetration when compared against the sun; the light from a 1000W HPS is usable for a a few feet while light from the sun is usable to plants after traveling 93 million miles!

    Even outdoors, lower buds tend to grow smaller than the top ones (cannabis is a wind-pollinated plant and favors buds that are higher up). But the lack of growth in lower buds becomes more pronounced indoors. With grow lights, the vast majority of the light produced is aimed straight down over the top of the plant, and in most setups the sides don't get much light at all. Because of these reasons, the Christmas Tree shape can be really inefficient indoors, causing your plant to have just one big, top bud and many smaller ones that don't weigh nearly as much.

    The main idea of plant training is to create several top colas to take the best advantage of indoor grow lights so less light is lost and yields are higher overall.

    Make many cannabis colas instead of just one!

    Like these Vanilla Kush Girls they both have 8 colas not one top.

    Three main types of marijuana plant training
    1. Bending and securing parts of the plant while causing little-to-no physical damage to the plant
    2. Damaging or removing parts of the plant in a strategic way to get it to grow in a more desirable shape
    3. Manipulating timelines to get faster or bigger yields

    Usually growers will use more than one of these types of training because they can complement each other, but it's also possible to use just one and not any others. For example when growing auto-flowering strains you can't manipulate timelines and it's generally advised not to damage the plant since they have such a short life and that could result in stunting. So for auto-flowering plants, the main option is just bending and securing.

    Next: a breakdown of each plant training technique so your garden has tons of colas!

    Vanilla Kush with 16 colas....

    (LST) - LST is the process of bending stems and securing them in place. The general idea is to bend tall stems down and away from the middle of the plant as it grows so the plant takes on a more flat and wide shape. This should be started when the plant is still a seedling since its young stems will be flexible, while the stems of older plants become rigid and woody. Some growers use the term "LST" as an umbrella term to cover all types of plant training, while others use it to refer only to bending.

    Plant Twisty Ties are commonly used to secure stems in place after bending them over, but lots of growers get creative (pipe cleaners, soft coated wire, etc). Just don't use anything "sharp" like chicken wire because it cuts into the plant as it grows.

    No-Technique Plant Training - This is cannabis plant training in its most basic form. If it's your first grow and you want to keep things simple, or if you don't have much time and want to do the bare minimum to get results, this is for you!

    The main stem was bent over 90° when the plant was very young, so all the lower branches were able to grow up and become main colas. Bending the main stem was the only training done to this plant, no fancy techniques!


    Supercropping - this technique is a more "extreme" kind of bending, and is used for stems that are too tall but have become woody and difficult to bend. With supercropping you "soften up" the stem first before bending it at an extreme angle. Supercropping can be incredibly helpful towards wrangling an out-of-control plant, and it has a few other benefits too because it can stress the plant in a "good" way.

    Supercropping involves extreme bending, but without hurting the "skin" of your plant


    Screen of Green (ScrOG) is a technique where growers use a screen over their plants and weave stems through the screen as they grow. When the plant starts making buds it's already in a flat, table-top shape with lots of well-spaced bud sites under the grow lights. The screen also provides support for heavy buds.


    Topping & FIMing are ways of damaging the plant at a very young age to lead to plants growing mare bud sites.

    In this next picture, notice how the plant sort of "splits" at one point near the base of the plant. That split is where the plant was topped or FIMed and the apical dominance was broken. As a result, the plant turned many stems into main colas instead of only growing big buds on one main stem


    Manifolding - This describes a sequence of topping the plant two times in a specific way so that it forms a wide "manifold" at the base of the plant. This is an easy way to achieve a lot of training without much time on your part. A benefit of training the plant with manifolding is buds tend to grow bigger, longer and more uniform than they would with some other training methods. The downside is topping your plant twice can add a week or two onto your grow.

    Hey! I'm a cannabis grower and breeder focused on kush strains. But grow many other types and crosses "hybrids" Been in the Cannabis grow game, since 1995 was a struggle. Finally, the light, in the tunnel; is lit. Legalization, has taken a lot of stress off the grow game. I grow in Denver, supply dispensary's and edible makers. They love the trim.

    If, you, find yourself; in need of grow help. Don't hesitate to ask me. I would be more thn happy, to help you out.

    It all starts with a seed. StayLifted Stay Safe Stay Awesome c2

    "Great information"
    Pros - The pictures are awesome help!
    Cons - Not familiar with some words.
    I'm just very new to growing anything and looking for detailed information on this subject. I have 2 growing under lights. One is near harvest I think. Both from seed planted 3 weeks apart. Don't know the strains. A really nice young man mailed me 3 seeds. Only one survived. The second was from some left over stems and seeds from a friend. After I harvest at end of November I hope, I'd like to clone 2 plants and use this techniche.

    "Green machine"
    Pros - Good diverse methodology and current technology
    Cons - Gotta train um all.
    Good introduction to different methods with amazing results.

    These methods will require a new grower to test and fine-tune each method thru trial and error.

    Expect lots of errors. But after a lil'time, you'll be all kick-back, with green thumbs.
