How to Increase the Potency of Your Cannabis Harvest with HST

Cannabis cultivation can be a challenging yet rewarding pursuit, especially for those seeking high-quality yields with potent effects. While there are many factors that contribute to the growth and development of cannabis plants, utilizing high-stress training (HST) techniques can increase the potency of your harvest. However, many growers may be perplexed by the different types of HST and how to properly apply them. In this article, we will explore what HST is, why it is beneficial, when to use it, and step-by-step instructions on how to perform it. By the end of this article, you will have the knowledge and tools needed to take your cannabis cultivation to the next level.

What is HST?


What Is Hst?
Have you ever heard of HST? No, it’s not a new kind of high-speed train, but rather an abbreviation for a cannabis cultivation technique that can increase the potency of your harvest. HST stands for High-Stress Training, which involves subjecting your plants to various forms of stress – such as topping or bending them – to promote more growth and resin production. In this section of the article, we’ll delve deeper into the different methods of HST and how they can benefit your cannabis crop.


Topping is a popular high stress training (HST) technique that involves removing the top section of the plant’s main stem. This forces the plant to produce two new main shoots instead of one, resulting in two main colas instead of one. Using topping, you can effectively double the amount of buds that you harvest from a single plant.

To ensure the success of topping, you will need to make sure that you have the proper tools, including a sharp pair of scissors or pruning shears. You will also need to take care to make a clean cut, as a jagged cut may damage the plant and lead to infection.

The Steps for Topping Your Plant are:

Step 1: Wait until your plant has at least five sets of leaves.
Step 2: Locate the main stem’s topmost part, just above the fifth set of leaves.
Step 3: Using your sharp scissors or pruning shears, cut the top from the main stem.
Step 4: Clip off any excess growth on the stem below the cut to ensure proper air flow and to save valuable nutrients for the top of the plant.
Step 5: Wait for new growth to appear at the stem’s base. This should happen within a few days, and these new shoots will become your two new main colas.

Remember that topping can temporarily slow the growth of your plant, but the end result will be worth it. By topping your cannabis plant, you will increase the amount of buds you can harvest from a single plant and also promote thick, bushy growth that will help boost your yield.


One of the HST techniques for increasing the potency of your cannabis harvest is LST, or Low Stress Training. By bending and manipulating the plant’s branches, LST can help distribute nutrients and encourage equal growth throughout the plant, resulting in larger and more potent buds. Here are some step-by-step instructions for performing LST on your cannabis plant:

Tools Needed:

Soft Ties: Nylon or Velcro ties that won’t damage the plant’s delicate branches.
Supporting Stakes: Bamboo or plastic stakes that can support the plant as it grows.
Scissors: Clean, sharp scissors for pruning any excess foliage.

Step-by-Step Instructions:

1. Start LST in the vegetative stage, once the plant has 3-4 nodes.

2. Use a soft tie to gently bend the main stem of the plant parallel to the soil.

3. Secure the bent stem to a supporting stake with another soft tie, so that it maintains a horizontal position.

4. Wait a few days for the plant to adjust to the new position, then gently bend the upper branches downward and away from the center of the plant.

5. Use soft ties to secure these branches to the supporting stake, so that they maintain a horizontal position as well.

6. Repeat this process every few days, as the plant grows and develops new branches.

7. Continue LST until the plant reaches about 75% of its desired height, then stop bending and begin maintaining the plant’s shape by pruning excess foliage.

Tips for Successful LST:

– Be gentle when bending and manipulating the plant’s branches, to avoid damaging or breaking them.

– Use soft ties that won’t damage the plant’s delicate branches, and don’t tie too tightly or too close to the stem.

– Make sure the supporting stakes are sturdy enough to support the weight of the plant as it grows.

– Keep an eye on the plant as it grows, and adjust the LST as necessary to maintain an even canopy and encourage equal growth.

Common Mistakes to Avoid:

– Bending or manipulating the plant too much or too aggressively, which can cause damage or stress.

– Tying too tightly or too close to the stem, which can restrict the flow of nutrients and water.

– Neglecting to adjust the LST as the plant grows, which can result in uneven growth and an uneven canopy.

By following these steps and tips, you can successfully use LST as an HST technique to increase the potency and yield of your cannabis harvest.


Mainlining, also known as “manifolding,” is another HST technique that involves creating a symmetrical plant structure with multiple main colas. This technique can increase the yield and potency of your cannabis harvest by promoting even light distribution and maximizing space utilization.

To perform mainlining, you will need a young, healthy plant with at least four nodes. Here is a step-by-step guide:

Steps Description
Step 1: Identify the first node below the plant’s top and remove everything below it, including any lower branches and leaves. This will focus the plant’s energy on the top nodes and promote more growth.
Step 2: Once the plant has grown out its top node, identify the two nodes closest to the plant’s base and remove all other nodes and branches. This will create two main branches, which will eventually become the main colas.
Step 3: As the two main branches grow, top them just above their fourth node, leaving four nodes below the cut. This will continue to promote even growth and create four new branches, two on each main branch.
Step 4: Repeat Step 3 with each of the four branches, creating eight evenly spaced branches in total.
Step 5: Remove any new branches that grow between the main branches to keep the plant symmetrical.
Step 6: Tie down each branch with a soft plant tie to promote even growth and light distribution.
Step 7: Continue to train the plant as it grows, tying down new growth to maintain an even canopy and promote maximum light exposure to all branches.

Remember, mainlining can be a bit more complex than other HST techniques and requires patience and attention to detail. However, if done correctly, it can result in an abundant and high-quality cannabis harvest.

Why Use HST to Increase Potency?

Why Use Hst To Increase Potency?
It’s no secret that cannabis enthusiasts love high potency buds. If you’re aiming for a more potent harvest, you might want to consider using high-stress training (HST) methods such as topping, low-stress training (LST), or mainlining. By subjecting your plants to controlled stress during the growing process, you can increase the cannabinoid and terpene content in your buds. But why exactly does HST lead to a more potent harvest? Let’s delve into the science behind it.

Stress Response

When plants are subjected to stress, they develop unique survival mechanisms. Cannabis plants are no different, and when they are exposed to HST techniques, they undergo a stress response that can ultimately lead to increased potency. The following table explains the different stress responses that cannabis plants exhibit in response to HST and how they contribute to increased potency:

Stress Response Explanation Contribution to Increased Potency
Increased Trichome Production Trichomes are the tiny resin glands on the cannabis plant that contain valuable cannabinoids and terpenes. When the plant is subjected to stress, it produces more trichomes as a defense mechanism. The increased number of trichomes on the plant means a higher concentration of cannabinoids and terpenes, ultimately leading to increased potency.
THC Conversion When exposed to stress, the plant converts THCA (the non-psychoactive form of THC) to delta-9 THC, the psychoactive form of THC that is responsible for the high associated with cannabis consumption. The conversion of THCA to delta-9 THC ultimately leads to increased potency, as the psychoactive form of THC is more desirable for recreational users.
Higher Cannabinoid Production As a response to stress, the cannabis plant produces higher levels of cannabinoids in an effort to protect itself. The increased production of cannabinoids, including THC and CBD, leads to a higher concentration of cannabinoids in the plant material, ultimately contributing to increased potency.

The stress response of cannabis plants to HST techniques is an important factor in increasing potency, as it leads to increased trichome production, THC conversion, and cannabinoid production. As a result, cannabis growers who utilize HST techniques can potentially achieve a more potent cannabis harvest.

Increased Light Exposure

One of the key benefits of using High Stress Training (HST) on your cannabis plants is the potential for increased light exposure. This increased light exposure can lead to a more potent harvest as the plant is able to photosynthesize more efficiently, creating more energy for growth and bud development.

So, how exactly does increased light exposure occur through HST techniques?

First, let’s consider the topping technique. When you top your cannabis plant, you remove the top of the main stem, which causes the two nodes below the cut to grow into two separate stems. This creates a bushier plant with more nodes and more potential bud sites. The increased number of bud sites allows for more light to penetrate deeper into the plant, which can result in more energy and growth.

Similarly, the low-stress training (LST) technique involves bending and tying down the stems of the plant to create a more even canopy. This technique allows for more light to reach lower branches and bud sites, which would have otherwise been overshadowed by taller branches. By training the plant to grow in a more even canopy, you are ensuring that each bud site is receiving the maximum amount of light possible, creating more energy for growth and potency.

Finally, mainlining involves a similar process of creating an even canopy, with eight evenly spaced colas. By training the plant to grow in this way, it ensures that each cola is receiving an equal amount of light, allowing for more energy and growth for each individual cola.

By using HST techniques, you are creating a more efficient use of light within your cannabis plants, which can lead to a more potent and productive harvest.

When to Use HST?

When To Use Hst?
One of the most perplexing aspects of using HST to increase the potency of your cannabis harvest is knowing exactly when to apply these techniques. Determining the right time to use HST requires careful consideration of the growth stage of your plants and the specific outcomes you hope to achieve. In this section, we will explore the ideal growth stages for applying HST techniques and provide guidance on choosing the right method for your needs.

Seedling/Early Veg Stage

During the seedling/early veg stage, HST should be used with caution. This is because the plants are still very fragile and may not respond well to stress. However, if done correctly, HST can greatly increase the potency of the final harvest. Below is a table outlining the potential benefits and risks of using HST during the seedling/early veg stage.

Benefits of HST in Seedling/Early Veg Stage Risks of HST in Seedling/Early Veg Stage
Can increase yield and potency by creating a more robust and bushy plant Plants are fragile and may not respond well to stress
Can help to shape the plant for better light penetration and more uniform growth Increased risk of plant damage or death
Stress response can trigger greater production of cannabinoids May stunt growth and delay harvest

It is important to note that if HST is to be used during this stage of growth, it should only be done once the plant has developed a few sets of leaves and is showing signs of strong growth. The plant should also be in a healthy state and not showing any signs of stress or nutrient deficiencies. It is also important to start with a very gentle form of HST, such as LST, and observe the plant’s response before progressing to more aggressive techniques. With proper care and attention, HST during the seedling/early veg stage can be a valuable tool for increasing the potency of your final harvest.

Late Veg/Early Flowering Stage

During the late veg and early flowering stage, cannabis plants are typically well established with a strong root system and multiple branches. This is the ideal time to begin HST techniques to increase the potency of your harvest.

Benefits of HST during Late Veg/Early Flowering Stage:

Benefit Description
Bigger Buds By manipulating the growth pattern of the plant, you can promote larger, denser buds.
Higher Potency The stress response from HST techniques can increase the production of THC and other cannabinoids.
Better Light Penetration By opening up the canopy, more light can reach lower buds, resulting in more even growth and higher yields

Which HST to Use:

During the late veg and early flowering stage, topping and LST are the most commonly used HST techniques. Mainlining can also be used at this stage, but may require more time for the plant to recover before beginning the flowering stage.

Topping: This technique involves cutting off the tip of the main stem to promote the growth of multiple colas. It can be done once or multiple times, depending on the size of the plant and desired results. Topping during this stage can lead to larger colas and an even canopy.

LST: Low Stress Training involves using gentle pressure to bend and shape the branches of the plant. This technique can promote an even canopy, better light penetration, and larger colas. It is important to avoid causing any damage to the plant during LST.

How to Do HST:

Regardless of which technique you choose, it is important to have the right tools and follow step-by-step instructions carefully. Here are some tips for successful HST during the late veg/early flowering stage:

Tools Needed:

– Sterilized trimming scissors or pruners
– Soft plant ties (such as garden twine)
– Bamboo stakes or other support structures, if using LST

Step-by-Step Instructions for Topping:

1. Wait until the plant has at least 4-5 nodes (sets of leaves) before topping.
2. Using sterilized scissors or pruners, cut off the tip of the stem above the fourth or fifth node.
3. Wait a few days for the plant to recover before resuming normal feeding and watering.

Step-by-Step Instructions for LST:

1. Identify which branches you want to train – ideally, choose the branches that are growing horizontally or at a slight angle.
2. Gently tie the branch down using soft plant ties, being careful not to break or damage the stem.
3. Secure the plant tie to a nearby support structure (such as a bamboo stake) to hold the branch in place.
4. Repeat with other desired branches.

Tips for Successful HST:

– Only use HST techniques on healthy plants with strong root systems.
– Wait for the plant to recover and resume normal growth before applying additional stress.
– Monitor the plant carefully for signs of stress, such as wilting or yellowing leaves.
– As the plant grows, continue to adjust and modify your HST techniques as necessary to maintain an even canopy.

Common Mistakes to Avoid:

– Applying too much stress too quickly, which can damage or kill the plant.
– Using dirty or non-sterilized tools, which can introduce harmful bacteria or fungi to the plant.
– Neglecting to monitor the plant for signs of stress or disease.

By using HST techniques during the late veg/early flowering stage, you can promote bigger buds, higher potency, and better light penetration for a more successful cannabis harvest.

Flowering Stage

During the flowering stage, your plants will start to develop buds and you can no longer use topping or LST as they can stress the plant too much and reduce yields. However, mainlining can still be used at this stage to increase potency.

1. Continue training the main colas – During the flowering stage, the main colas of your plant will start to stretch and grow taller. You can use stakes or cages to help support them and train them to grow horizontally.

2. Remove unnecessary growth – As your plant focuses its energy on growing buds, you’ll want to remove any unnecessary growth that won’t lead to the development of dense buds. Look for small, underdeveloped branches or stems that won’t receive enough light and remove them.

3. Monitor nutrient levels – During the flowering stage, your plant will have different nutrient needs than during the vegetative stage. Be sure to monitor and adjust your nutrient levels accordingly. Too much nitrogen at this stage can lead to reduced bud development and potency.

4. Control humidity and temperature – High humidity levels can lead to mold growth on your buds, so it’s important to keep humidity levels under control during the flowering stage. Temperature can also affect the potency of your harvest, so keep an eye on the temperature of your growing environment.

5. Harvest at the right time – The timing of your harvest can greatly affect the potency of your buds. Wait until the trichomes on your buds have turned a milky white color before harvesting for maximum potency.

Determining Which HST Method to Use

Determining which HST method to use is crucial in order to maximize the yield and potency of your cannabis plants. The method you choose will depend on several factors, including the strain of cannabis you are growing, the size and shape of your plants, and your personal preferences. Here are some factors to consider when choosing which HST method to use:

Factor to Consider Possible HST Methods to Use
Plant size and shape – Topping: for plants with a single main stem and a tall, thin shape
– LST: for plants with several main stems and a bushy shape
– Mainlining: for plants with a symmetrical shape and many evenly spaced nodes
Strain of cannabis – Sativa-dominant strains: may require more aggressive HST methods such as topping or mainlining to control growth and maximize yields
– Indica-dominant strains: may require less aggressive HST methods such as LST to avoid stunting growth
Growth stage – Seedling/early vegetative stage: topping or mainlining can be used to create more main stems and increase overall plant volume
– Late vegetative/early flowering stage: LST can be used to train the plant to spread out and maximize light exposure
– Flowering stage: HST should be avoided in order to prevent stress that can reduce yields and potency
Personal preferences – Some growers prefer certain HST methods based on personal experience and success
– Experimentation with different methods can lead to a preferred technique and higher yields

Consider all of these factors carefully when determining which HST method to use on your cannabis plants. Remember, each plant is unique and may respond differently to different HST techniques. It is important to stay observant and adjust as necessary in order to achieve the best results possible.

How to Do HST?

Once you have determined which HST method to use, it’s time to get started with the actual process. Proper execution is key to avoid damaging your plants and to achieve the best results. In this section, we will go through the steps you should take to successfully perform HST, as well as the tools you’ll need to get the job done. Pay close attention to our tips and advice to ensure that your plants remain healthy and strong throughout the process. Let’s dive into the specifics of how to do HST!

Tools Needed

Performing HST on your cannabis plants requires a few essential tools to ensure successful results. Make sure you have the following tools at hand before starting:

  • Sharp scissors: You’ll need to make clean cuts when topping your plants or pruning them during LST.
  • Cannabis-friendly training wire: Look for flexible, coated wire, which won’t harm your plant’s delicate branches.
  • Bamboo sticks or other supports: You’ll need to prop up your plants during LST, so they don’t fall over or damage themselves.
  • Plant ties: You’ll need to secure the branches of your plants during LST, so they stay in place, but without damaging them.
  • Clean, sharp pruning shears: You’ll need them to precisely prune your plant’s leaves during mainlining.

Having these tools handy will make your HST process go smoother, and help you avoid frustration and suboptimal results. Make sure your tools are clean and sanitized, as well, to avoid any potential contamination of your plants.

Step-by-Step Instructions for Topping

To perform topping, you will need a sharp pair of scissors or pruning shears. Follow these step-by-step instructions to successfully top your cannabis plants:

Step 1: Wait until the plant has at least 4-5 sets of leaves and is in the vegetative stage.
Step 2: Identify the main stem of the plant, which is the center stem that runs from the root system all the way up to the top of the plant.
Step 3: Locate the node where the 4th or 5th set of leaves meets the main stem. This will be the location where you will make the cut.
Step 4: Using your sharp scissors or pruning shears, make a clean and precise cut about ¼ inch above the node. Do not leave too much of a stem or too little – the perfect length is about the size of a thumbnail.
Step 5: After you cut off the top portion of the main stem, two new branches will begin to grow from the node where you made the cut. These branches will grow outwards, creating a “V” shape.
Step 6: Allow the plant to recover from the stress of topping for at least a week before performing any further HST. During this time, the plant will redirect its energy to the remaining branches, resulting in more nodes and increased yield.

It’s important to keep in mind that topping should only be done during the vegetative stage, and not during the flowering stage. Also, it’s recommended to only top your plant once so as not to cause too much stress. With proper technique, topping can increase the potency and yield of your cannabis harvest.

Step-by-Step Instructions for LST

Low Stress Training (LST) is an HST technique that involves tying down the branches of your cannabis plant to create a more even canopy and increase the light exposure to the lower parts of the plant. Here are some step-by-step instructions for LST:

  1. Start Early: Begin LST training in the vegetative stage when the plant is still flexible and can be trained to grow in the desired shape.
  2. Prepare: Gather all necessary tools, including plant ties or soft wire and stakes to hold the ties down.
  3. Select Branches: Identifying the two or three main branches that you want to train and gently pull the branches down and away from the center of the plant to create an even canopy.
  4. Secure: Secure the stems to the pot or growing medium with plant ties or soft wire, being careful not to damage the plant.
  5. Observe: Monitor the plant and make necessary adjustments to the ties as the branches continue to grow and bend towards the light.
  6. Repeat: Repeat the process for all desired branches until you have achieved the desired shape and even canopy.
  7. Keep it Low Stress: Remember, the key is to create a low stress environment for the plant. Do not over-tighten the ties, and do not cause any damage or stress to the plant.

By following these step-by-step instructions, you can effectively use LST to increase the potency of your cannabis harvest. Keep in mind that LST can take some time and patience, but the end result will be a healthier and more productive plant.

Step-by-Step Instructions for Mainlining

Step Instructions
Step 1 Select a young plant with a strong central stem and at least four pairs of leaves. Remove any side branches or growth below the fourth set of leaves.
Step 2 Once you have removed the unwanted growth, use a pair of scissors or pruning shears to cut off the top of the plant, just above the second set of leaves. This will encourage the plant to grow two new stems at the same level.
Step 3 As soon as the two new stems have grown to the same height, cut off the tops of those stems again, just above the second set of leaves. Repeat this process until there are 8 main colas growing at the same level.
Step 4 Once there are 8 main colas growing at the same level, use gardening wire to gently bend each stem down and away from the plant’s center, creating a symmetrical canopy. Be sure not to break any branches or damage the stems.
Step 5 Allow the plant to continue growing under the new canopy for 1-2 weeks, then begin removing any growth from the bottom third of the plant to focus energy on the main colas.
Step 6 Continue to maintain the canopy by gently bending and tying down any new growth that emerges above the canopy, until the plant reaches its desired height.
Step 7 As the plant begins to flower, trim off any excess leaves to allow more light and air to reach the buds. Harvest the plant when the buds have fully matured.

Mainlining is a technique that can greatly increase the potency and yield of your cannabis harvest. By creating a symmetrical canopy of 8 main colas, you can ensure that each cola receives even light exposure and nutrients, resulting in larger, denser buds. Follow these step-by-step instructions to successfully mainline your cannabis plant. Remember to be patient and gentle throughout the process to avoid any damage to the plant.
