Background

 

This article is for growers who have not yet entered the flowering phase. In addition, for gardeners who are planning to grow cannabis indoors, this information needs to be read. It will come in handy! This content comes from the feedback of JT Grow Light customers.

 

How to increase the yield of plants that have already started flowering? If you have not taken any measures during the growth period of cannabis, consider that you have one last chance. And it cannot be missed. In addition, there are several ways to influence the final harvest. This content not only comprehensively considers effective solutions for growing in the hue phase, but also studies it during the flowering process (the beginning of bud formation). So, assuming that your greenhouse plants have begun to actively grow buds, what can you really do to increase the yield during this growth stage?

 

1. Increase light intensity

 

It is well known that light is actually a supplement and therefore a transfer of life energy. In short, if plants get more light output, they will produce larger buds. There is nothing supernatural. Everything is obvious and understandable.

 

3 Main Ways to Increase Light Intensity

 

  •  Install Better Cannabis Grow Lights
  • It is very important to keep grow lights as close to the plants as possible without overloading the plants.
  • Prune your new buds so that they develop horizontally under the light. Pruning during growth allows your plants to keep the light as close as possible without causing strong light burning on the tallest leaves.

 

When marijuana is surrounded by vegetation, it will actively react by trying to grow taller to get better lighting.

 

2. Choose the Right Cannabis LED Grow Lights for Flowering

 

For the best yield, density, and bud size, high-quality grow lights should be used when the buds are forming.

3. Provide the Right Spectrum During Bud Formation

 

Using LED plant lights that contain more red light of different wavelengths during the flowering stage will be more effective than using cannabis plant grow lights that contain more blue light.

 

Choose a cannabis LED grow light that contains the following:

  • White;
  • Red;
  • Far Red (infrared wavelength);


Typically, the instructions for such lights contain a light temperature definition of 3000K, or indicate "far red" as an indication that the entire required spectrum is displayed here. Visually, this light appears pink, yellow, or reddish.

 

Cannabis LED grow lights usually need to be kept at least 40 cm above the plants to prevent bleaching and burning.

 

4. Follow the recommended defoliation schedule for defoliation

 

Most growers use targeted strategic defoliation to maximize their yields. This term refers to the process of removing specific leaves at specific points in bud development. In effect, it "disrupts" the plant's natural process and causes the buds to grow larger and denser than normal. This technique works best on seedlings of varieties with increased green volume. Conversely, if your plant does not have many leaves, defoliation will slow growth, so don't go overboard with this operation.

 

The basic principles of soil defoliation are as follows:

 

  • At the beginning of the flowering period (weeks 1 to 3): Remove all large, fan-shaped leaves on long stems. This exposes your newly developed bud structure to direct light. The kidneys need direct light to expand.
  • After 3 weeks, perform another defoliation only when the plant looks thick. Exposing the main branches to direct light will help the plant to "focus" on the development of buds.
  • After the second major defoliation, remove only the leaves that cover the buds, or if the plant becomes too dense in the middle and bottom of the bush.
  •  

You will find that the buds are getting bigger and bigger, and a chic harvest is just around the corner!

High-yield results are obvious!


Attention! The defoliation schedule outlined above is fairly typical for most indoor growers, regardless of the variety chosen by the grower. However, the timing of some operations may change due to various factors, mainly the cultivation conditions.

 

5. Do not ignore the appearance of abnormal symptoms!

 

After entering the flowering stage, the plant has increasingly higher requirements for the ratio of nutrients and its overall nutritional value. Make sure you quickly diagnose and correct any nutrient deficiencies, insect attacks, diseases or other visible problems. Unhealthy plants lack the energy to form buds.


Identify and correct plant problems immediately to avoid damage to the crop. In the photo below, the plant is too close to the light and shows signs of mild stress.

The cannabis leaves in the photo are too bright and the edges are bent upwards. And they themselves become crisp and dry.

 

6. Environmental factors for optimizing cannabis growth

 

There are several key factors to keep in mind. They are mainly related to the microclimate of your grow room / grow box during the flowering stage. If you really want to maximize your yields, consider the following triggers:

 

  • Temperature - keep the temperature between +18°C and +26°C as much as possible. Increased temperatures are associated with loose or "airy" buds, weaker bud smell, reduced immunity, mold formation, insect infestation (especially if the buds are also wet).

 

  • Humidity - after the buds start to develop, do not let the environment be too humid. High humidity can cause mold infestation and bud rot, and also inhibit bud growth. High density / large (high humidity makes it difficult to effectively transport water through key plant nodes).

 

  • Specificity - when the interior of the grow room / grow box has reflective walls, light loss can be prevented. There are many options for increasing reflectivity, such as painting the walls with white paint or covering them with mylar. Providing more light to your plants will help your buds grow densely.

 

  • Air circulation - In addition to maintaining the correct temperature and humidity, it is also important to give your plants a breeze and plenty of fresh air. Effective air circulation prevents many problems and speeds up plant growth, thereby increasing overall yields.

 

  • Adding additional CO2 to the air - Some growers add additional CO2 to the air to increase yields. Plants need CO2 for photosynthesis, and (in some cases) adding CO2 to the air allows plants to extract more energy from the same amount of light. There are many different ways to increase CO2 levels, some of which are more effective than others!

 

A large number of cannabis growers focus on finding new nutrients and additives to increase yields, but ignore the current environmental issues. If the environment created is not ideal, focusing on the above tips may make a much greater difference to your crop than any product you can buy in a container.

 

7. Harvest in time

 

Most importantly, do not start harvesting too early! Please note this argument: cannabis buds will gain significant weight in the last two weeks before peak maturity. Let this become your unshakable law and the results will come quickly.

 

Even harvesting a few weeks in advance can halve the final harvest! In addition, these bots will not be as strong, shiny and aromatic. Do not trust this with your own experience, trust the grower.

 

The cannabis plant is ready for harvest when most of the white hairs on the buds turn black and curl.

Experienced growers usually check the shiny trichomes under a magnifying glass to ensure the proper harvesting time.

 

8. Continuous cultivation

 

This advice is not specific to the flowering period, but its importance cannot be overemphasized. After all, if you do not pause between harvests, the grower will constantly get finished products of different varieties throughout the year. Of course, we are not saying that there will be a harvest every day (although it is possible, but very laborious). However, the cyclical nature of the process and the absence of pauses in the growth process produce amazing results, and it is likely that soon you will have too much. But we all know what you can do with it ;) Interestingly, it is not uncommon for cannabis growers to equip at least two workspaces and ensure continuous harvesting.

 

Finally

 

Continuing with the idea of ​​​​a continuous process, it is crucial not to stop developing and keep learning. Amazing discoveries are made almost every day, which means there is always more to learn about our ever-growing production!
