When growing cannabis indoors, the grower needs a pot. A properly selected container is the key to the active development and healthy growth of cannabis, as well as an abundant and high-quality harvest. In it, the root system of the plant must feel comfortable in order to fully perform its functions. Only well-developed roots are able to provide the aboveground part of the plant with a balanced nutrition and sufficient amount of water. They, in turn, will need:
In the constant presence of moisture. The roots should never completely dry out, otherwise this will lead to wilting, and then to the death of the entire plant;
Good aeration. Oxygen must be able to penetrate into the container without hindrance. This promotes the rapid development of the whole plant, strengthens its immunity, and also prevents the appearance of mold and root rot.
At first glance, everything is simple, so many beginners prefer not to bother, choosing an ordinary flower pot, bought at the nearest flower shop. With the acquisition of experience, the gardener begins to realize that things are a little more complicated. Different types of containers have their own advantages and disadvantages, as well as fundamental differences that can simplify or complicate the cultivation process. A grower must know all these nuances so that the marijuana harvest does not turn into a disappointment.
Types of marijuana pots
Four types of pots are best suited for growing cannabis:
Plastic pots for cannabis cultivation
These pots are the most popular and common. They can be easily found in any flower shop. They are sold in a wide range, and therefore it will not be difficult to find a suitable volume. Most often, such a pot comes with a special saucer-stand, which is necessary to collect excess water. For this, drainage holes must be present at the bottom of the pot. Without them, moisture will begin to collect in the pot, which will lead to waterlogging of the soil and, as a result, the death of the plant. If there is no drainage in the plastic container, then it can be easily done by yourself.
Clay pots for cannabis cultivation
Terracotta pots are yellow or red fired clay products, usually not covered with glaze. They were used by humans for centuries until cheaper containers made of artificial materials replaced them.
In general, clay pots are no different from plastic pots, but there are a few nuances. First of all, they are much heavier, which makes them difficult to lift with a large volume of soil. Also, products made from this material are able to accumulate excess moisture inside themselves, which can lead to the appearance of mold. On hot days, this can play into the hands of the grower, creating a cooling effect on the root system. Under normal conditions, excessive moisture will lead to mold, so when using terracotta containers, care should be taken to ensure that the soil is well aerated.
Smart fabric pots for growing marijuana
These containers are very similar in appearance to a bag. They are called “smart” because they help the cannabis root system develop naturally. In plastic or clay pots, the roots that reach the walls are twisted and intertwined. As a result, they lose their ability to effectively absorb nutrients, macronutrients and moisture.
In smart tissue containers, these roots are automatically air-pruned. Reaching the walls, they easily pass through them, going out. The part of the root that has come out dries up, and the part remaining in the container releases secondary roots. As a result, the root system takes on a natural shape, which contributes to its regular development, which has a positive effect on the aerial part of the plant.
Fabric pots are made from durable, environmentally friendly materials. They are safe to use an unlimited number of times. They are not attacked by mold, germs and fungi. The fabric used allows oxygen to freely penetrate into the inside of the container to the roots, as well as effectively remove excess moisture, which significantly reduces the likelihood of root rot.
The disadvantages of “smart” tissue containers for cannabis include:
Due to the good aeration, the soil dries out in them much faster than in plastic and clay pots. In them, marijuana will have to be watered more often;
Due to the rapid removal of moisture, not all types of soil are compatible with them.
Cannabis cultivation air pots
Air pots are cylindrical plastic containers. Their walls have many holes, which are located at the top of the protruding cones. The inner walls also have a loose conical surface that guides the roots towards the outer holes. As a result, they go outside and, upon contact with air, die off naturally, thereby encouraging the development of secondary roots in another place. This allows the plant to form a dense and efficient root system with multiple active branches.
Their main difference from “smart” containers is their high strength and stability. It is much more difficult to turn them over, which is very useful in conditions of limited free space. In air pots, moisture evaporates quickly, which requires more frequent watering from the gardener. Also, water can easily flow out through the holes, so a saucer will definitely come in handy for collecting it.
Marijuana seedling pots
Containers for cannabis seedlings are selected according to the same principles as for adult seedlings. First of all, they need good drainage to grow rapidly. Little soil is placed in small pots, and therefore it will dry out quickly. Frequent watering without enough drainage holes will inevitably lead to mold on the cannabis, which will quickly kill the young, immature plant.
A good solution for planting sprouts are ordinary plastic cups with a volume of 100-200 ml or special peat pots for seedlings. The latter can significantly facilitate and secure the process of transplanting seedlings, because for this the plant does not need to be taken out of the container. It is placed in a new growth site along with the peat pot. Over time, it decomposes in the soil, allowing the roots to grow unhindered outside its walls.
Do not forget that any transplant is a stress for the plant, which can significantly slow down its development. That is why autoflowers try to plant immediately in the final pot.
Hemp pot saucer
After watering, excess water is drained from the pot through the drainage holes. To prevent it from flooding the growbox and causing inconvenience to the grower, it is necessary to use a special saucer that will collect it. As a rule, it comes with the pot, but sometimes you have to buy it separately.
For fabric and air containers, the saucer should be more voluminous, since they remove moisture more efficiently. Its diameter must necessarily exceed the diameter of the pot, because water will also seep through their walls.
Very often, emptying the saucers can turn into daily agony for the gardener. This is especially true when cultivating a large number of plants. But even from under several large plants it is not so easy to get a saucer of water, especially in a confined space. To eliminate this inconvenience, special large pallets that can fit several plants will help. And if you place them at an angle, then you can make sure that all excess water flows independently into an easily emptied tank.
Hemp pot size
The volume of a suitable pot directly depends on the growth of the plant. The lower it is, the less developed its root system. For example, autoflowers will thrive in small containers, while large sativa marijuana bushes will need a few dozen liters pots.
When choosing a suitable pot, they are guided by the maximum growth of the plant. For every 30 cm of growth, she needs about 7-8 liters of soil. However, these are only approximate figures, because all plants grow in different ways. Some grow slender and elongated, while some grow curvy and wide. This fact should be taken into account.
Transplanting cannabis into a new pot
Every grower knows that if you plant cannabis seeds or plant clones in a small container, there will certainly come a time when they have to be replanted. Their root system will develop to such a size that it will no longer be able to perform its function normally in a confined space. As a result, the seedling will not receive enough moisture and nutrients. Its development will stop.
Transplanting hemp bushes is a painstaking process that requires increased attention and accuracy from the gardener. One careless movement can damage the roots, causing the cannabis to spend some time rehabilitating. If, when growing photoperiodic varieties, this time can be compensated by extending the growing stage of hemp, then with the autos the grower will have to say goodbye to part of the crop.
The best time to transplant cannabis is when the roots reach the walls of the container. They can easily penetrate deep into the new pot, providing the growing aerial part with everything it needs without interruption. It is customary to perform the first plant transplant when it grows 3-4 internodes.
Marijuana transplant process
First, prepare a large container by filling it with soil and making a recess commensurate with the small pot. Then a palm is applied to the surface of the soil of the old container so that the stem of the plant passes between the index and middle fingers. The pot is turned over, as a result of which the potting plant, together with the soil, should easily come out of it. This is best done when the soil is moderately moist. Then it will not be heavy and crumbly. The plant is placed in the prepared recess and covered with a small amount of soil, securely fixing it.
