Low Stress Training (LST) Autoflowering Guide

Contents:

Applying plant training techniques at the right times, with the right cultivar can really increase the size of the canopy, the growth structure and overall yield. In this article we explain low stress training, how it is performed, the benefits associated and out top tips for L.S.T.

1. What Does L.S.T Mean?

Referring to a method of training Cannabis plants that causes very little stress, and allows a grower to manipulate the shape of their canopy at will. Low stress training is a very simple technique that has many benefits and can be performed multiple times if necessary. 

L.S.T is the art of lowering certain points of the canopy, in order to create a uniform, multi tipped canopy and to expose light to the inner parts of the plants.
 

Unlike super-cropping, or topping which are classed as high-stress techniques, L.S.T is an inexpensive and excellent way for beginner growers to become more hands-on with their plants, reducing plant height and increasing production.

2. Controlling Apical Dominance

Cannabis plants naturally grow with an apical dominance, meaning they will always produce one central cola with side branches. By applying L.S.T to Cannabis plants, the production of the growth hormone Auxin is cut short, allowing the growth energy to be converted into a lateral growth. This is particularly convenient when attempting to control the final height, for those who are limited with growing space, prefer a low-profile plant for decoration purposes, or plan to grow in a Sea of Green scenario.

Disrupting Apical Dominance

•  Growth hormone Auxin is responsible for the vertical growth of plants.

•  Tying down autoflowering plants controls the final height and structure.

•  The side branches will be encouraged to grow alongside the main crown shoots.

•  Plants will develop a bushy and wide profile once L.S.T is performed. 

3. How Is Low Stress Training Done? 

The principle behind L.S.T is to take the tallest point of your autoflowering plant, and to bend it down to a height in the canopy that is in line with the side branches. The technique only needs to be performed once to completely disrupt the vertically dominant growth structure and will reduce the height of the cultivar as flowering commences.

 

There are different ways to tie side branches down and using twine, metal wire and even weights in some cases prove the most effective.
 

What To Consider 

•  The technique only needs to be applied once to be performed successfully.

•  Using twine or thin metal wire works best and can be removed in an emergency.

•  Different cultivars will be more adapted to low stress training than others.

•  L.S.T should be applied during the first 3-4 weeks of an autoflowering plant’s life cycle.

4. Choosing The Right Cultivar

When it comes to low stress training and canopy manipulation, there will be some autoflowering cultivars that are more responsive than others. Hybrid and sativa dominant cultivars that can grow as tall as 150cm are the best candidates for tying down, like Orange Sherbet AutoA tall growing, sativa dominant, terpene powerhouse testing up to 24% THC that produces extremely big yield under LST training. 

However, it does not mean that short and stocky indica dominant varieties won’t benefit from receiving more direct light. Take Zkittlez Auto, for example, her rapid flowering time, huge yields, and a complex terp profile make Zkittlez Auto a must-have. This indica dominant will give you extra large yield and frosty purple nugs with proper L.S.T. training.

In the same way, topping certain autoflowering cultivars can affect the growth structure and final height of some strains in a negative sense, knowing which strains work best with L.S.T will save you time, space, and increase yields. Purple Lemonade is definitely one of the strains, that is just made for low stress training.

5. Top Tips On Low Stress Training Autoflowering Plants

1. Always do your research and see which strains the seed banks recommend for Sea of Green, SCROG, and L.S.T. This will give you the upper hand and allow you to control your plant height and growth structure with the intended results. 

2. When using string to tie plants, it is best to use a thick twine that is not able to slice through the stem as it grows. You will also want to make sure in the event of an emergency, you can easily cut the twine away and easily remove it.

3. L.S.T only needs to be performed once during the first 4 weeks to obtain the desired outcome. It is possible to tie to all of the side branches with some cultivars, allowing for a very bushy and dense-growing autoflower. 

4. Tying autoflowering plants down too late into flowers can have negative effects. Unless you are purposely growing your plants as low as possible due to stealth reasons outdoors, then we do not advise flowering plants with such a short height. 

5. Have a play with tying down one plant and leaving another to grow normally, so you can see how the plants change in structure. You will notice how the yield and amount of top buds are far superior on the plant that was tied down.

6. In Conclusion

Low stress training is an easy to perform, inexpensive way to stop apical dominance encouraging the plant to grow with a stocky and bushy characteristic. Not every strain will react as well as others, however, if you do find the perfect cultivar, alongside other training techniques such as SCROG and pruning, it is possible to achieve enormous harvests. Good luck practicing L.S.T on your autos and reaping the rewards.
