In the process of growing marijuana, we want to get larger volume, denser flowers, and higher levels of THC concentration.
Factors affecting cannabis production
There are many factors that determine the yield of cannabis grown indoors. The most important thing is the quality of the cannabis itself. Even if a good variety is only watered, the yield is still high. The prerequisite for obtaining high yields is to have high-quality seeds. Seeds are not good. No matter how hard you work, you will waste time and money.
The second is the planting method. In the case of adequate nutrition and a stable and suitable external environment, outdoor planting> aerosol cultivation> liquid cultivation> soil cultivation.
Next is the influence of the external environment. Effective light is the fundamental prerequisite of photosynthesis. Only through photosynthesis can hemp can produce organic matter (some fungi can synthesize organic matter in a dark environment, and Venus fly eating insects, but most plants synthesize organic matter. The method still relies on photosynthesis). Temperature and humidity determine the health of plants. They have been discussed before, so I won’t repeat them here.
The last is fertilization and shape change. Fertilization is like a meal for plants. Appropriate amount of fertilizer can effectively increase the yield of plants. Excessive chemical fertilizer will burn the roots of plants. The core idea of changing the shape is to change the main area where the plant absorbs auxin, so that auxin is needed by us. The plant part of the plant absorbs an appropriate amount to achieve the purpose of increasing production. In this chapter, I will highlight the two methods of fertilization and shape change.
Gardening tips to change the appearance of cannabis plants
There are many ways to change the shape, such as topping, layering, and grafting. Before we understand these methods, we must understand the core factor that affects the shape of plants-auxin.
Auxin is distributed in all parts of plants and is the first plant hormone to be discovered. The most important chemical substance in auxin is 3-indole acetic acid. Auxin has the functions of regulating the growth rate of stems, inhibiting lateral buds, and promoting rooting. It is used in agriculture to promote rooting of cuttings and has significant effects. When the concentration is too small or too large, auxin will inhibit the growth and development of a certain part of the plant. But at the right concentration, auxin will greatly promote growth and development.
We found that the appropriate concentration of roots is the lowest, flower buds are in the middle, and stems require the highest concentration of auxin. Therefore, in order to obtain tall and dense plants, we have to create a suitable internal hormone level for the plants and change the distribution and concentration of auxin.
Auxin has two characteristics. The first is anti-gravity. Auxin is always transported in the opposite direction of gravity and loves to go high. The second characteristic is the distribution of protection from the sun. The auxin always prefers to be distributed in the place where the light intensity is small. The second characteristic obeys the first characteristic first.
In a marijuana plant, auxin is always distributed at the top of the sun. Therefore, marijuana that grows freely always has only one main stem and many side branches, which grow uniquely upward. Our method of changing the shape and increasing production is based on this situation. During the vegetative period of the plant, the stem is relatively soft and the plant has strong resistance to resistance.
Step 1: When there are 4-6 nodes on the main stem, bend the main stem.
The layering is called LST (low stress training) by foreigners. The first step is to break the situation where the auxin is distributed in a large amount at the top. When the stem is soft, use a thick and soft band to fix the rhizome connection part of the plant to fix the plant, and use the band to bend the top stem. You must be slow in the bending process, and don’t break her. If it is difficult to bend once, you can slowly break it day by day.
Step 2: Bend the other tallest stem
Continue to break the top rule. After the plant has adapted to this shape, bend the top of the stem to make the height of the stems of the plant converge, so that the auxin is evenly distributed in each stem, and the light is used to make each stem The poles can play their maximum growth potential. New shoots that are too tender can wait a little longer and never break them.
Step 3: Repeat
Because the main stem is the thickest, the main stem tends to have more auxin, so the main stem will still extend new branches upward. After there are about 3 branches in the horizontal direction of the main stem, we can no longer bend the main stem, or it will grow into a snake. We let the main stem continue to grow upwards and bend the branches on the main stem to allow them to get more auxin and become the new main stem. Then bend these new main stems, and so on.
Step 4: Watch the cannabis plant flourish during the flowering period!
Stop when the marijuana grows its calyx, because the marijuana entering the pre-flowering period will no longer change its body shape. The branches of cannabis entering the pre-flowering period should be evenly pointed upwards, and the crooked branches affect the yield.
This is a schematic diagram of the layering method.
This is a picture of the success of the layering.
The comparison chart of beading and no beading, the output difference is 3 times.
In the process of layering, we must be careful to bend the plants to prevent breaking the branches. The tools we need are
- Plant metal wire or soft plant ties (the uncoated rubber cord or metal wire has the risk of cutting branches)
- Small stake
- Small hand drill
First, make a hole on the side of the flowerpot to fix the plant with a strap. Before bending the plant, use a wooden strip and a strap to fix the main stem first to prevent the root from being pulled when bending. Once she was broken, taped her up and secured, she could always reply in a few days. Repeat these operations until she no longer changes her body shape.
Layering is a commonly used method of increasing yield in horticulture. It has little irritation to plants. As long as you are careful, it will not kill plants, but the benefits it brings are beyond imagination. The skillful use of layering is a must-learn course for novice growers.
In addition to layering can effectively change the auxin distribution of cannabis, topping and rubbing are also often used in the process of growing cannabis.
Topping and rubbing branches will destroy the fibrous structure of hemp and damage the plant cells of hemp, which will make the plant feel threatened or unable to continue to reproduce, resulting in a variety of stress responses and even death. Therefore, many growers abroad call similar methods High Stress Training (HST). These similar methods change the distribution of auxin on the one hand, making the auxin more evenly distributed near the calyx; on the other hand, it also strongly stimulates cannabis, allowing her to produce more cannabis oil and a stronger smell. But it may also cause marijuana to produce an adverse stress response, such as loss of pigment, returning to the vegetative period, degeneration, sickness and infection and many other adverse symptoms. Therefore, when we use high-stress training, we must limit the number of times and only do it during the nutritional period with better resistance.
Use clean plant scissors to completely subtract the branches from the roots of the new branches. When constructing, the main cut is the center position of the structure or the high branches, so that the auxin is scattered from the height and the center and evenly distributed in the surrounding branches. During the process, keep the environment clean to prevent the plants from infecting or getting sick.
Similar to the topping technique, the difference is that the pruning point is at the roots of the new leaves. Pinching can achieve a variety of effects, it will promote the secretion of auxin in large quantities, it will promote the production of lignin in large quantities, and it will prompt many plant stem cells to change the direction of differentiation. For hemp, there are two main effects, forcing the remaining leaves of hemp to differentiate into new branches, because a large amount of auxin will inhibit the development of the leaves but will strengthen the growth of the stem, plus the promotion of lignin on the branches, this The method is very likely to give birth to new branches. Another use is to strengthen the stress response of cannabis, allowing her to produce more growth hormone and cannabis oil. When using this method, be sure to keep all parts clean, because residual leaves will increase the risk of infection.
This method is more useful, basically to make the plant have a stronger stem. Use clean fingers to gently pinch the part of the stem before the bifurcation point. This part should be behind the part where the branches grow on the stem. Then knead slowly to destroy the fiber structure in the stem. When you feel that the inside becomes soft and loose, you can control it to a soft but not broken degree, and then fix it with a plant strap. This method will allow the plant to grow a big bag after branching, make the stem thicker, and strengthen the secretion and accumulation of stem auxin. Once this thick node grows, auxin will be explosively transported to the top of the branches, which greatly promotes the growth of lush flowers. This method is usually used 5-10 days before the pre-flowering period. If the stalk is broken or broken, wrap it with tape and fix it with a tie. This method will slow down the growth of branches and calyx before it is successful, but after the plant recovers, the accumulated nutrients will be transported to the upper layer of the structure in large quantities, which is a method that wants to promote first.
In actual operation, we will mix and apply various methods, which can achieve good results. The core idea is to distribute auxin evenly and in large quantities near the calyx, and pay attention to hygiene when using it to prevent plants from getting sick and dying when they are weak.
The methods described above are only part of the gardening techniques, they will also produce many interesting combinations of techniques. In addition, some gardening techniques can also increase yield, such as pressing soil, cuttings, and grafting. These interesting combinations and techniques will be introduced in later chapters.
