Plant Training Techniques: The Tie-Down Method

Low Stress Training (LST) it’s the practice of gently bending stems and tying them in place to drastically change the shape of the plant. This is done to create multiple bud sites, even out the canopy, and overall help you use light more efficiently.

Using LST techniques like the tie-down method can drastically increase your yields without changing your setup.

1. The Tie-Down Method: A LST Technique

Low stress training is used to form a relatively flat, even canopy. This exposes many bud sites to direct light instead of just the top main bud.

As a result, trained plants can naturally produce more and bigger buds in the same grow space than untrained plants.

There are other cannabis plant training techniques that are are called high stress techniques (HST) but they may stress your plant or slow down growth.

2. The Tie-Down Method

The tie-down method lets you train your plants to grow in the exact shape and size you want, giving indoor growers the ability to make the most out of their grow space.

The idea behind the tie-down technique is to bend and gently tie-down your plant’s branches and leaves so they develop into an even canopy.

This will promote multiple bud sites and all will get equally as much light as possible to all your plants, resulting in much bigger yields from the same grow lights compared to plants that were not trained.

It can also be used to reduce the height of your plants that are getting too tall for your grow tent or are growing taller than your other plants and leaving them in shadow.

This LST method is also the easiest to do and it doesn’t require planning, you just have to try and level all branches by tying them down, nothing else.

You will most definitely get the best results if you start from training from when the plant has grown the third or fourth pair of true leaves up to the first weeks of flowering.


• Bigger yields from the exact same grow lights and setup (compared to plants grown normally).

• Complete control over height, shape, and size of the plant (especially helpful indoors).

• Plants produce many big buds instead of just a single main bud and a lot of tiny ones (prevents pop-corn buds).


• You’ll need to perform this technique up to 2 times per week depending on the strain (can result in a lot fo work).

• There is no exact guide, you have to tie-down according to the structure of your plant and all plants are different.

The Tie-Down Method on Autoflowers

Autoflowers are usually bushy and they don’t produce big enough side branches for them to get enough light and develop well.

Even though the tie-down method stresses your plant significantly less other HST method, you can prevent stress by growing a strain that takes training well, like our Zkittlez Auto.

If you train the stem downwards then the lower branches will start growing more rapidly and soon they will be on the same level as the stem, this will allow the side branches to receive more light thus producing denser buds.

3. Starting Training

First of all, have in mind that this is a general guide. The way you perform this technique may change according to the strain you grow and the way it grows.

Training usually begins once the plant has three or four pairs of true leaves (or is big enough to allow you to do it) and is most effective when the plant is young.

The goal is to have all new growth even. Training needs to continue as the plants grow and become bushier. Low stress training isn’t something that you can do once and then forget about, it’s an ongoing process.

What Material Should I Use?

The goal of tying down is to manipulate the plant to our liking without stressing it.

This means you have to use materials that are not too sharp like rubber-coated metal wire, clothing hangers, or even pipe cleaners. Thinner materials like string and chicken wire are usually too sharp and can cut through your cannabis plant.

Tip : Avoid using string because the fibers can get stuck on the trichomes and will result in your flowers being full of string residue.

Where do I Tie-down?

Depending on the type of material you are using, there are different ways of holding your plant down.

If you’re using strings, pipe cleaners, or rubber-coated wire you can make small holes around the pot so you can hold the plant down after tying. If you’re using metal materials like thick wire or something similar, you can stick it in the medium.

Be aware that depending on the material it can oxidize and can harm your plant, the best type of materials are rubber-coated wire or plastic strings.

Tip : If you still have doubts about what to use or where to buy, look for an old electronic in your house and cut the wire off. If you think the wire will get wet when watering, remove the wire inside, and use the rubber coating it to tie your plant.

Bend The Stem or Branches

Start by carefully feeling how flexible the stem or branch is that you want to bend, so you know if you can work with it without problems. If you suspect it might break then you should slightly bend it before tying down to reduce the chances of snapping.

Tie The Highest Branch

Tie the highest branch so that the former top is at a lower level than the rest of the plant. Look carefully to see if the stem bends smoothly and do not force it.

It is essential that you start any low-stress training as soon as possible. It’s best to start when your plant is very young (three to four pairs of leaves). Although if you decide to tie-down midway through the vegetating phase it is also going to work.

Once the stem is bent, tie it to the pot using the material of your choice, use the material of your choice to secure it gently but firmly in the desired position.

Sometimes it is also a good idea to remove some of the larger fan leaves that are blocking light even after training, this is up to you and is not recommended for beginners.

The main idea is to keep all the stems about the same distance from the light.

Organize the canopy

After you’ve done the initial tie-downs, your plant will continue growing and will develop newly grown branches.

Ideally, you want to continue to bend the tallest stems down and tie-down the new branches to avoid vertical growth.

Watch, Wait And Repeat

24 hours after bending the branches will start to grow up again and after a couple of days, there will be new branches growing.

You will have to continue to tie branches and level your canopy slowly, day by day, especially the small new side branches that are growing vertically.

The branches that are already tied down will start growing up after they’ve grown enough, you will also have to move the tie to the tip of the branches so they continue to grow horizontally.

Don’t worry about the initial messy appearance of your plants when you first tie them. After a couple of days, it will start coming into the shape you want.


If done correctly, you will seed your plant developing various bud sites and thanks to your training they will receive the amount of light they need to grow big and dense.

It is recommended that the tie-down method is performed until the first weeks of flowering (pre-flowering stage). After your plant stops growing and is focused on fattening the buds you should stop, continuing this can stress her and she can end up turning into a hermaphrodite.

4. In Conclusion

The tie-down method is the way to grow if you want to use the maximum out of your growing equipment. Performing it correctly will guarantee better buds and a higher yield than growing your plant normally (in your setup).

A good option to avoid stress form this technique is by using strains like our Orange Sherbet Auto that not only takes it well but it’s recommended.

How To Perform Low Stress Training On Cannabis For Better Yields

Low stress training (LST) is a growing technique that involves manipulating the shape of cannabis plants to produce better yields. It’s easy, and can actually be a lot of fun to do! Read on to learn how to LST like a pro!


Even if you don’t have a lot of cannabis growing experience under your belt, you should still consider giving low stress training a try. Low stress training (LST for short) is a simple and methodical way to increase your yield while controlling the height and shape of your plants.


As a yield-boosting training method, LST allows growers to make the most of their available space and light. At its simplest, this training technique involves gently bending and tying down cannabis plant branches and stems. We do this for two reasons: First, cannabis normally grows one large main stem that develops one large, elongated cola. This exists alongside other, smaller side-branches with smaller buds to suit. The natural tendency for cannabis to grow into this “Christmas tree” shape is known as apical dominance. With LST, the goal is to break this apical dominance, instead flattening out the canopy to grow at the same height.

This brings us to the second reason behind LST: better light distribution. By bending and securing plants in a way that breaks apical dominance and evens the height of the canopy, all areas of the plant will be exposed to greater light distribution, thus creating more viable buds sites and larger yields at the end! Not only that, but LST doesn’t even require you to alter your growing setup to achieve great results. All you need is some know-how and a few essential tools.


If you’re familiar with growing cannabis, you’ll know that plants normally develop a few fat buds toward the top of the plant, with several smaller buds below. This is not only true of cannabis, but many other flowers, fruits, and veggies used by humans.

Over centuries, horticulturists have devised ways to get more out of their plants using simple training techniques. These techniques can involve topping and pruning plants, as well as bending, ScrOG, and all manner of other methods. Although they all differ slightly, each one ensures optimal use of light, space, and resources.

Low stress training is a modern variant of an old technique used to force fruiting trees to grow in a flat structure. The ancient Egyptians are thought to have used similar methods to grow fig trees horizontally more than 3,000 years ago. A method known as espalier then became very popular in 17th century Europe, and made espaliered (ie. carefully trimmed and shaped) hedgerows of fruit trees a common sight. The practice was also widely used in apple and pear orchards—not just for better harvests, but more so as a way to beautify the landscape.


A key element of this training technique lies plainly in its name; “low stress” is what separates this method from “high stress” techniques like topping. Whereas the latter technique involves cutting off the plant’s main growing tip in an effort to redistribute growth hormone, LST is much gentler. Not only does this decrease the risk of over-stressing your plant, but it means less time spent waiting for your plant to recover and adapt to high stress changes. With LST, there’s no inherent pruning or trimming, although this method is often used alongside other, more severe tek. All in all, plants that undergo LST respond very favourably, and will reward you for your efforts and finesse with healthy, hefty yields of huge buds.


To properly perform LST on your plants, you need the following equipment:

  • Rubber-coated plant wire/soft plant ties
  • Thin wooden/bamboo stakes
  • Small hand drill
  • Duct tape

Although this method requires little supplies, we seriously advise against using regular string to hold down your plants. Regular string or wire is often too thin or harsh, and will cut into the stems and do more harm than good. It’s much better to seek out special plant ties suited for the job.


We keep referring to tying down stems and branches, but to where?! All you need to do is drill several holes around the rim of your growing container. Now you can loop the ties through the holes and around the branches to hold the shoots securely in place.

For even more support options, some thin wooden or bamboo stakes with a length of about 30cm work great to hold everything in place. And lastly, because accidents can happen when we’re bending branches, get some duct tape so you can patch up any snaps or breaks.


Let’s get to the interesting bits: how to LST your cannabis plants!


To start, it’s all about breaking that apical dominance. Begin by bending your main stem gently down toward the rim of the container. Using the soft plant wire and the pre-drilled holes, securely tie the stem in place. Ta da! You’ve just flattened the canopy and made way for future, horizontal growth. This way, light will reach many more buds sites, which in turn will result in a greater yield.

Tips: Some growers choose to first top the main stem, then bend the secondary shoots out to the side. This way, the plant will take on more of a “spider” shape. But even if you’re performing standard LST—without topping—you may want to consider some light defoliation to increase light penetration.


One thing to keep in mind with LST is that you always want to maintain a flat canopy, so no one branch is taller than the other. When it comes to shaping, it’s important to bend shoots outward and away from the main stem. This isn’t rocket science per se, but it is helpful to have a desired shape in mind rather than just winging it. Even this can work, but beginners are better off doing some basic planning to avoid any pitfalls.

Moreover, sometimes accidents can happen, say if you accidentally snap a branch as you’re bending it. No reason to freak out! Plants are actually more robust than one may think. As long as a branch hasn’t entirely come off, you can always fix such mishaps with some duct tape. It will take a week or so to heal, but it won’t be the end of the world.

Likewise, know that LST isn’t something you do once and then you’re done. This technique requires consistent upkeep. The reason for this is that your plant will keep growing regardless of what shape you’ve moulded it into. In time, shoots will grow and leaves will get larger. For this reason, you’ll want to re-adjust your bends once in a while to make sure the canopy stays nicely even.


Some people think LST is for indoor growers only—but this is far from true! Don’t forget, plant training isn’t exactly new, and it began as an outdoor method to boot. If you live in a colder climate such as the UK and other parts of Northern Europe, outdoor LST can be a good way to increase yield during the summer season, even if you’re not blessed with much sunshine. Likewise, LST can also be a helpful tool to keep your outdoor cannabis plants low-profile. A plant that you tied down for a flatter canopy won’t just give you better yields, but will also draw less attention compared to a towering weed plant somewhere out in the wild, just waiting to be discovered!

As for when you should start with LST, the answer here is: as soon as possible. Once your plant is comfortably in its vegetative stage, it will be primed and ready for manipulation. You don’t want to go too early before the plant has established a few good nodes, but you also don’t want to wait around. There is only one time where LST can be genuinely problematic, and this is when your plant is already into full flowering. At this stage, the plant’s stems may be too rigid to bend, and you risk potentially snapping a branch holding your precious buds. This aside, however, you can start LST at pretty much any time during the vegetative phase. The earlier the better.


Can you LST autoflowers? Absolutely!

Autoflowers grow quickly and don’t require a change in light cycle to initiate flowering, meaning they don’t have much time to recover from high stress training methods like topping and defoliation. With LST, however, plants can still benefit from the optimal light exposure, and they won’t need time to recover since it doesn’t cause any real damage. Although the autos of old likely would not hold up well to LST, the new generation is more than capable of handling it.

In fact, LST can be a great way to boost the yield of your autoflowering ladies! Just know that autos will go into flowering after about 4 weeks, so you should have already made up your mind whether you want to LST them or not! Get started as early as possible for best results.

Here are the top 5 strains to utilise the LST method with:


Chocolate Haze is an absolute treat for the taste buds, with hints of chocolate, sweetness, and earthiness lighting up the tongue when smoked or vaped. The unique terpene profile within the flowers was gifted to this strain via the breeding of parent strains OG Chocolate Thai and Cannalope Haze. Chocolate Haze is a sativa-dominant lady that features 95% sativa genetics and just 5% indica genetics. This results in a potent high that is cerebral, motivating, and very energising. Fuelled by a THC content of 20%, this high takes hold fast, and is often the source of some very interesting and deep conversations.

Chocolate Haze can be grown successfully both indoors and outdoors, and is a strong contender for the LST method. Indoor plants cultivated within grow rooms or tents are capable of rewarding growers with yields of between 475–525g/m². Outdoor plants grown within garden beds or pots are able to produce harvests of up to 500g/plant, and are ready for harvest during late October. Chocolate Haze favours a mild climate and features a flowering time of 9–10 weeks.
