What Is LST Autoflower growing?

Low-stress training refers to a weed cultivation technique used to maximize the overall yield of your plant with the least stress. The method requires a gentle manipulation of the cannabis plant structure to encourage light usage of lower branches.

Alternative options include high-stress training (HST) methods, like pruning and topping. We don’t, however, recommend high-stress techniques with most autoflowering plants, since they temporarily inhibit growth.

Plants from autoflower seeds have a built-in genetic schedule that predetermines the plant’s transition time from vegetative growth to the flowering period. While some strains can withstand high-stress training, seasoned growers concur that photoperiod plants are best suited for HST.

Why use the LST Autoflower method?

LST is employed to manage stretching, increase yield output, and maximize light utilization in your plant. The technique reduces the amount of vertical growth required with the least amount of stress possible. Allowing the cannabis plants to spread out in lateral growth, producing as many leaves and branches as they can.

Their main objective is to make more flowers that attract pollen and develop seeds. Crops start to produce flowers at the tips of the major branches, and the main cola has the most flowers. It extends toward the sun to take advantage of as much sunlight as possible.

Autoflowering cannabis produces one large bud and a few side-by-side smaller buds. The main stem gets the most sun and makes the most resinous buds. This is referred to as apical dominance.

When you start low-stress training, you’ll discourage apical dominance, allowing the lower branches access to the light source. By tying branches down, you’ll make them all the same height, allowing them to grow more quickly.

Once you low stress train the shoots that have grown higher, you deceive your auto into believing that its main stem is gone. It strives hard to develop those other branches to optimize its chances of survival. After performing the LST, your plants will have a bushier growth and wide profile.

This growing technique is ideal if vertical space is limited and you don’t want your plant to grow tall. When evenly spread, your autoflower plant will divert all its energy to producing glistening, terpene-rich buds.

When to start LST on your Autoflowers cannabis plant

Autoflower growers have two alternatives when conducting LST. Many choose to LST from the start to increase yields and maximize a limited grow space. More experienced growers employ LST to increase their overall production at a later stage by tying branches.

LST allows them to harvest more dense buds from a single plant. The autoflower plant grows at its fastest during the early weeks of the flowering stage. You can perform the LST training from the beginning of the plant’s life cycle until the last weeks of flowering.

  1. At the early signs of your plants’ growth, you can start LST on the first or second true leaves that have fully developed. Your cannabis plants start growing upward at this point, but you can start training it to produce numerous tops.You’ll obtain the best effects from this approach early in the plant’s life. If you opt to use LST as your plants grow their first branches do so gently to prevent damaging the entire plant.
  2. The second option occurs during the first few weeks of blooming or a week before the flowering stage. At this time, a cannabis plant is growing the fastest and generating the most branches.The outcome won’t be as effective as when you begin from scratch, but it’ll still enhance the yield from one plant.

How long should you use the LST technique?

You should stop low-stress training your autoflower crops once the pre-flowering stage begins. It’s crucial to quit at this point since any additional pressure, no matter how minor, could negatively impact your yield.

Due to their short growth cycle, auto plants don’t have much time to recover from any mistakes or damage.

Where to apply the LST techniques on cannabis plants

You can apply LST plant training on autoflowers whether you’re cultivating indoors with grow lights or outside in the sunlight. Whatever the light source, many growers choose to employ these techniques to enhance the yield of their crops.

If you have limited vertical space in your grow area, using LST helps to promote lateral growth and improve yields of each plant.

How to LST autoflowers weed plants

Typically, cannabis plant growth taks the Christmas tree shape, where the main stem experiences apical dominance and grow tall. Using LST, the light exposure is spread to the lower branches, encouraging more bud sights to develop.

There are various low-stress training techniques, like SCROG and the Tie-down method. Choosing the right method depends on how you want your cannabis plants to grow.

Below are three step-by-step guides for cannabis LST. You may train your auto-flowering plants with minimal stress using various basic, intermediate, and advanced techniques. With the help of these cannabis LST guidelines, even inexperienced growers can enhance their yields.

Tie-down method

The tie-down method is one of the most straightforward LST autoflower approaches when growing cannabis at home. It entails drilling holes along the pot’s edge and using any flexible string to bend and hold down the plant.

Begin with the main branch to level the side branches at the main cola.

Step 1: Initial Planning

Get everything you’ll need to LST your autoflowers together. You need a few little components to start LST training. Get some stuff to tie your plants together.

The LST autoflower technique’s most practical variation involves attaching the weed plants to their grow pots. Using this method, you can easily rotate or move the plant without disassembling and reassembling anything. It’s easy to connect the ties using a cloth or air pots.

Use clips or safety pins for fabric pots, as air pots have accessible holes. Having some stakes or bamboo on hand is a good idea when low-stress training your autoflowers. They aid in securing the plant against the ties’ pulling force.

Step 2: Make Preparations

After you have everything you require, it’s time to prepare your pots. Create holes around the equally spaced rims or in fastening safety pins when using fabric pots. Air pot users can skip this step.

Transfer the seedlings to the pots, but be careful not to overfill them with soil. Allow about an inch from the top to make it simple to reach and deal with the holes.

Stake the main stem of your cannabis plant right to ensure stability. All that is necessary is a little stake, which aids in the plant’s ability to withstand the pressure from the ties.

Step 3: Tying Down

The next stage in your autoflowers’ low-stress training includes tying down the branches. All areas of the foliage should get equal light to form a level, even canopy. Even though it’s simple, it’s ideal for studying your plants first rather than just jumping in.

Take your time evaluating your cannabis plant from all sides and deciding where you need changes. It’s appropriate to start low-stress training once you have a general idea of what to do. Bend the branches into position slowly and delicately to check their flexibility.

Understanding the branches’ flex limit allows you to tie the branches without causing damage. Use a non-abrasive plant tie and pull the string until it firmly secures the branch.

Step 4: Maintenance

The low-stress training technique is a continuous process. It needs regular care and upkeep to attain optimal effects. Consider it a constant process of directing your cannabis in the direction of your desired shape.

Review the low-stress training procedure for your autoflowers every day. You’ll be shocked to see how fast your trained branches and stems stretch toward the light source. LST your auto plants continuously all through the vegetative phase.

Pre-flowering signs indicate that you can now unwind. Making minor tweaks is acceptable, but you should have completed most of the work.

Step 5: Flowering

The majority of your autoflowers’ low-stress training is over once flowering begins. It’d help if you now placed your focus on maintenance. Prune and trim smaller immature side branches or leaves to focus energy on flower production.

It promotes plant ventilation, lowers moisture retention, and hinders mildew and mold growth. The real benefit of low-stress training autoflowers will become evident once harvest time comes along. With this straightforward low-stress training method, you can maximize the potential of your cannabis and never look back.


  • It’s cheap and straightforward.
  • You can move your plants around without any issues.


  • During the vegetative phase of your plant, you must tie each branch separately, which can take some time.

Screen of Green

The Screen of Green or ScrOG setup is a slightly more advanced low-stress training method. Start low-stress training by holding and bending branches while employing a net or other screen.

It helps to keep the side branches at the same height. While it requires more setup, the tie-down approach improves yields.

Step 1: DIY Time

The screen is the critical component of the ScrOG autoflower technique. It must be strong enough to support the weight of your auto plant as it grows. Depending on your configuration and budget, you can create a screen from various materials.

Many growers construct a wooden square frame and string over it to create the net. They then mount the screen by suspending it from above or supporting it below. Plant trellis netting fastened to poles is another straightforward method of making a screen for low-stress training.

Growers stretch the trellis between the posts positioned at the corners of your grow space. Any technique for building a screen is acceptable as long as it’s strong and won’t break when expanding.

Step 2: Installation

It’s time to install your screen to start low-stress training your autoflower strains once you’ve finished building it. Mount the screen on support from the bottom or firmly fasten it to the fixtures above. Your autoflower cannabis should ideally be receiving early low-stress training.

Install the screen in this situation a few inches above the plant tops as they are right now. Soon, your plant will reach the screen where the branches will be attached as they grow. Lower the net over the plants if you’re starting your autoflowers’ low-stress training later than usual.

Stretch the branches out and place them into holes spaced appropriately, taking care not to break any limbs. Once every branch is positioned equally and protrudes through the screen’s openings, tie plants to secure them.

Step 3: The screening process

Now that the screen is in place, you can begin low-stress training your autoflower seeds. The goal is to provide light penetration to each branch to produce abundant yields of sticky, dense buds. Start by training your autoflowers into the screen’s outer branches first.

Stretch each branch far from the main stem at the center to widen the canopy’s lateral spread. Tie the string around and over it to secure the branch in place. It supports the upcoming large buds and prevents the branch from migrating back toward the center.

Continue fastening each main stem as you work your way around the plant. You’ll start to see the fruits of your labor as you proceed toward the lower branches. If any branches don’t stretch toward the light, don’t worry too much; they’ll reposition themselves after a few hours.

Training your autoflowers with a ScrOG configuration generates a spread-out canopy that maximizes direct light penetration and boosts productivity.

Step 4: Optimize your screen

The next phase in ScrOG-ing your autoflowers is to enhance effectiveness, which is optional. The goal is to remove any vegetation and growth beneath the screen.

This step of low-stress training ensures that energy is directed to the trained branches exposed to more light and developing buds.

Step 5: Maintain your screen

The final phase of low-stress training autoflowers is ongoing maintenance. Every day or two, check in on your plants and evaluate them. To maintain an even canopy, tie down any new growth beginning to grow past the other branches.

LST your autoflowering plant continuously until blossoming begins to show. It would help if you now had a wonderfully flat canopy prepared to jump into activity and produce tons of bud.

Vertical Screen of Green

A vertical Screen of Green is a more advanced low-stress training method. The effects are remarkable, especially in bigger setups, but it requires more maintenance than the other approaches.

You should follow the same stages as the standard technique when low-stress training your auto plants in a vertical ScrOG.

The distinction is that you’re producing a vertical rather than a horizontal growth screen. The low-stress training technique aims to build a wall of growth in front of your lights. Growers achieve excellent results using this low-stress training technique for autoflowers with vertically mounted lighting.

A different application of the vertical ScrOG constructs a cylinder-shaped screen positioned around enough light. For a system resembling a tube with minimal light loss, weed plants push through the screen while facing the light. This technique to LST autoflower plants is best suited to seasoned growers because it requires a lot of maintenance.


  • The only thing that you have to do is to place the tops under the net.
  • During blossoming, SCRoG also helps the branches.


  • Because the net is attached to your growing tent, you won’t be able to relocate the plant.
  • Preparation is necessary since you have to place the net at the right time.

Sea of Green (SOG)

Similar to the ScrOG approach, Sea of Green encourages the growth of more plants with fewer bud sites. Remember that you must produce the same (or similar) strains when creating a Sea of Green.

It prevents growers from overpowering neighboring plants and causing them to grow at different rates.


  • Faster harvest than with other forms of training.
  • The most effective approach for small growing areas.


  • There are so many plants, hence, it is slightly easier to get mold or bugs.

Low-stress training advantages

Low-stress training autoflowers have far more benefits than downsides. The following advantages accrue to your marijuana if you’re ready to put in a little extra effort.

  • Utilizing space effectively
  • The highest degree of illumination
  • Enhanced airflow
  • It control stretching
  • More bud sites and dense bud production
  • Increased output yield

Low-stress training disadvantages

Low-stress training autoflowers don’t have any significant negatives. The drawbacks are simply cosmetic and won’t affect the quality of your cannabis other than adding a little extra work. These disadvantages include

  • Higher upkeep
  • Loss of the main cola

Tips to improve your LST techniques

Here are some suggestions to consider when low-stress training before you dash out to get your autoflower seeds.

  • It’s helpful to bend branches gently and with caution.
  • If the stems are too challenging to knot through the string, use plant clips or ties to fasten them to the screen.
  • If you see a lot of stretching, your plants probably need more light.
  • Always use soft knots; avoid thin nylon fabric and sharp, cutting wires.
  • Check the attachment points of your setup frequently when you LST autoflower plants. Inspect the ties or strings to ensure they aren’t swaying back and forth on the branches.

Low stress, high yields

Growers of various skill levels can develop remarkably productive cannabis plants using low-stress training techniques. The only requirements when you LST autoflower plants are time and everyday household items.

In exchange, you receive vigorous, thriving weed plants that produce abundant harvests of dense, sticky buds.
