Weighted LST: training with additional weights

## Introduction

Weighted LST (Low Stress Training) is an innovative training method especially for coco cultivation. By attaching temporary additional weights to the branches, you enforce uniform horizontal growth. As a result, all important canopy areas are optimally illuminated, which leads to increased yield quality. This method utilizes the rapid nutrient uptake in coco and the low buffering of the medium to achieve quickly visible effects.

## Why weighted LST in Coco cultivation?

Compared to conventional LST, where only the branches are fixed manually, the application of weights enables stronger yet gentle bending. This also reduces the amount of manual work required, as gravity continuously supports the desired effect. In the Coco medium, where the pH target value of 5.8 to 6.0 and frequent irrigation are essential, this method leads to faster and more precise training without the plant experiencing multiple stress phases.

## Requirements and materials

**Materials:**

- Soft, flexible plant ties or thin wire that gently holds the branches in place

- Small, mainly water-filled containers or sandbags as weights (100-200 g depending on branch thickness)

- Scissors or pliers to adjust the binding holders

- A stable, easily adjustable planting frame (optional, for support)

**Note:** Make sure the materials are clean to avoid infection. The weights should be sized to gently pull the branches down without causing breakage.

## Step-by-step instructions

### 1. preparation and selection of the branches

Select the main lateral branches that you want to train. In coco cultivation, the plants react quickly, so it is advisable to start training at an early vegetative stage (after the root system has established, from around 3-4 nodes). Make sure that the pH value of the nutrient solution is constantly between 5.8 and 6.0 and that watering is continuous. A stable nutrient mix with additional calcium and magnesium supports regeneration under mechanical stress.

### 2. gently move branches into position

Slowly bend the selected branches into horizontal or slightly downward positions, avoiding cracks in the bark. Use the plant ties prepared in advance for this. The aim is to fix the branch so that it remains permanently in the desired position and the entire canopy is evenly exposed.

### 3. attach weights

Once the branches have been positioned, attach small weights to the end of the branches. This is done in two steps:

- **First step:** Place the weight so that it gently pulls the branch further down. Make sure that the weight does not press directly on the plant, but is distributed over a soft cloth or a small fixing strap.

- Second step:** Check that the plant's muscle tone is maintained and that there are no cold or sore spots. The weights should be used as temporary aids and can be removed after a few days or weeks if the desired bending angle has been achieved.

### 4. regular control and adjustment

In coco cultivation, the plants grow very dynamically. Check daily that the weight distribution is still correct and that the branches are not bending back unintentionally. It may be necessary to adjust the weights or the tie holders. Ideally, these adjustments should be made at regular intervals to ensure that the canopy is always optimally aligned. Avoid excessive readjustments so as not to put the plant through unnecessary periods of stress.

## Important notes and safety

- Gentle handling:** The weighted LST is an extension of the classic LST and should always be carried out gently. Too much weight can break the branches or impede the sap flow.

- **Coco-specific care:** Due to the rapid nutrient uptake in Coco, it is advisable to adjust EC settings regularly. Timely calcium-magnesium supplementation helps to avoid possible deficiency symptoms.

- Cleanliness and hygiene:** Always use clean materials to avoid infections or mold growth.

## Conclusion

Weighted LST is an efficient training method that leads to optimal canopy formation, especially in coco cultivation. With the targeted use of additional weights, you can gently steer the plants in a horizontal growth direction. This technique minimizes manual intervention and supports the natural growth process of the plant. Through regular control and adjustment, you achieve an even distribution of light energy and thus significantly increase the yield quality.

This method makes it clear that the use of additional weights in coco cultivation is an effective training tool that integrates perfectly with the specific requirements of this medium.

## Pro Tips

- Start early in the vegetative stage (from 3-4 nodes).

- Always pay attention to the pH value of 5.8-6.0.

- Use soft materials to fix the branches.

- Check and adjust the weights daily.

- Ensure healthy calcium and magnesium levels in the nutrient solution.
