How do the best growers plan their cultivation - how many machines per 1 m2?

Before we discuss the topic of breeding, we should remember one thing.

Not every country legalizes the cultivation of cannabis. In the vast majority of countries, this may result in criminal liability. All content posted on our website is for curiosity purposes only and constitutes a collection of information about hemp. We do not encourage anyone to break the law. For example, in Poland, the cultivation of hemp other than fiber is illegal at the time of writing this entry and may result in legal sanctions, including imprisonment.

So how is it done in cannabis-friendly countries?

When planning to grow automatic marijuana strains, it is important to properly use the available space, both when growing outdoors and indoors (e.g. in a grow box). How many machines per 1 m2 can it fit to make the most of the space while still providing them with optimal conditions for development? Here are some tips:

how many machines per 1 m2

In cultivation outdoor (outside) it's simple. Growing outdoors gives plants more space, so you can plant fewer plants per square meter. Usually, depending on the size of the varieties, 1-1 plants per 2 m² is a good choice. There is no philosophy here. In this case, the grower is not limited by space as much as in cultivation indoor.

In the Room/Growbox: 1 to 4 plants can be placed in a space of 9 m², depending on the size of the plants and the cultivation technique. If we choose smaller varieties or use the Sea of ​​Green technique (SoG), we can fit more plants. For larger varieties and techniques such as Screen of Green (ScrOG), the number of plants will be smaller. You will learn more about the exact impact of both the selection of genetics and cultivation techniques on how many plants you can fit per 1 m2 later in this entry.

Always remember that it is crucial to provide enough space for each plant to grow and reach its full potential. Lighting, irrigation, and soil quality are also important for healthy growth, and you also need to find a place for these systems in the grow box.

Why is it not worth forcing many plants per m2 when growing indoors? Learn how to calculate how many machines per 1 m2

optimally how many machines per 1 m2

There are several important reasons why you should not force many plants into a grow box. As we know, it is impossible to grow bushes without providing them access to light. Every plant needs the right amount of light for optimal growth. Too many plants in a small area may lead to them shading each other, which negatively affects their development and yield.

good air circulation this is another thing that is crucial to plant health. Too dense cultivation can restrict air flow, which increases the risk of diseases and pests. Plants also need space for roots to develop. Packing plants too tightly may cause competition for root space, which negatively affects their growth and health.

Calculating how many machines per 1 m2 of cultivation is a sign of the grower's maturity and skills plant and crop management. More space between plants also makes them easier to access, allowing for better care, pruning and control over growth.

It therefore decreases risk of diseases and pests. Too dense cultivation creates ideal conditions for the development of diseases and pests. More space allows for better monitoring and control of these types of issues.

Optimally used space ensures even development. Leaving enough space between plants allows each of them to develop evenly, which translates into better yields. Marijuana plants can experience stress in thickets.

The above information helps you better understand why it is worth planning the place well and calculating how many machines per 1 m2 of cultivation.

Selection of appropriate genetics for cultivation per 1 m2

suitable variety indoor

Selecting the right strains will allow you to calculate how many plants per 1 m2 will fit in the grow box, based on the characteristics of individual genetics.

Selecting the right plant genetics for growing in a small area is a key element of success. To see how many plants will fit into the grow box per 1 m2, you need to choose the right varieties. It is worth paying attention to several features of a given strain in order to start estimating future cultivation on this basis.

  1. Size and height: Choose varieties that naturally grow smaller. Varieties indica and/ or indica-dominant plants tend to grow shorter and bushier, making them ideal for smaller spaces.
  2. Flowering time: Varieties with a shorter flowering time are preferred in smaller spaces because they allow for a shorter growing time. Indoors, this is often important because the shorter a variety grows, the less light it needs, which translates into lower electricity consumption.
  3. Yield: Look out for varieties known for high yields, even with smaller stature. Some varieties can produce heavy crops despite their compact size.
  4. Resistance: Look for varieties that are resistant to diseases and pests, which is especially important in confined spaces where problems can spread quickly.
  5. effect and aroma: Of course, it is also important to choose varieties that meet your personal preferences for effect and aroma.
  6. Automatics (autoflowering): Automatic varieties are a good choice for smaller spaces because they do not require changing the light cycle to flower and tend to grow smaller. You could also consider Fast Version strains.

Remember that each plant may react differently to its environment, so even the best selected genetics require proper care and constant adaptation to the best growing conditions.

Estimating how many machines per 1 m2 - dimensions and equipment of grow boxes

the appearance of a grow box

“How many plants per 1 m2” – the title itself revealed that it was about indoor cultivation. Of course, there are lucky people on our planet who not only live in countries where hemp cultivation is not punishable by imprisonment (e.g. Thailand or Uruguay), but can also afford to allocate entire rooms or rooms for their cultivation. Those who have less space use grow boxes.

For those who don't know, a growbox is a miniature greenhouse with an internal ecosystem that allows you to grow plants in optimal conditions all year round. There are miniature greenhouses for marijuana cultivation available on the market, which differ, among others, in: sizes. You can find grow boxes ranging from very small to impressively large. The size of such a grow box should be adapted to the specifications of the variety being cultivated. It is assumed that a strain reaching a height of about 80 centimeters develops best in a tent measuring 1 m x 1 m.

A typical grow box consists of the following elements:

  • Frame: Made of various materials, it provides the entire structure with the necessary strength.
  • Reflective material: Used to reflect and distribute light evenly.
  • Lighting: These are usually various types of lamps that provide a light source inside the grow box.
  • Fans: They enable mixing and exchange of air in the crop.
  • Carbon filters: Eliminates unwanted odors.
  • Air humidifiers: They regulate air humidity in the crop
  • Thermometers: Monitor the temperature in the growing environment.
  • Hygrometers: They track humidity levels.

List of tools helpful in cultivation indoor:

tools for indoor

In cultivation indoor marijuana, there are a number of tools that are necessary for effective and healthy cultivation. Below you will find a sample list of key tools:

  1. Watering can or irrigation system: For regular and even watering of plants.
  2. Trimming scissors: Necessary for pruning and shaping plants, as well as for harvesting crops.
  3. pH meter: To monitor and maintain optimal pH levels of water and soil.
  4. Soil moisture meter: Helps determine when plants need water.
  5. Thermometer and hygrometer: For monitoring the temperature and humidity in the grow room.
  6. Grow box lighting: LED lamps or other suitable grow lamps indoor.
  7. Fan: Ensures proper air circulation and helps keep plants healthy.
  8. Carbon filters: To eliminate odors from the growing room.
  9. timer: To control the light cycle of plants.
  10. Sleeveice protective: To protect your hands when working with plants.
  11. Pulverizer/sprayer: For spraying water or nutrient solutions.
  12. Fertilizers and supplements: Adapted to the needs of a specific phase of plant growth and flowering.

Choosing the right equipment is crucial because inappropriate or missing equipment can cause various problems, such as sunburn of plants, drying out, excessive temperature, and slow development. All this translates into the final success or failure of the entire project. Remember that the selection of tools depends on the scale (how many machines per 1 m2) and the specificity of your crop. It is important to adapt the equipment to your own needs and the conditions in which legal cultivation takes place.

What don to use?ice?

The size of the pot is crucial for the development of the plant. The size of the root system that develops underground is directly related to the size of the plant - a smaller 5-liter pot will result in a smaller plant than in a 10-liter pot. Diffice in plant sizes dominant genes Sativa i Indica they will also be visible in different pot sizes.

For autoflowering plants, it is not recommended to use pots that are too large. Typically, an autoflowering plant in an 11-liter pot will reach its maximum height, while in a 5-liter pot it will grow to a medium size and in a 3-liter pot it will be relatively small. If your grower has enough space, the best choice is pots with a capacity of 11-12 liters, which will allow the plants to develop without restrictions.

Very generally, but it can be assumed that:

  • A 3-liter pot means the plant's height is from 35 to 50 centimeters
  • A 5-7 liter pot means the plant is about 60 centimeters high
  • An 8-10 liter pot is up to 100 centimeters high
  • A 12 liter pot is 100 to 130 centimeters high
    pot size and plant size

    Appropriate selection of the pot size allows you to estimate how many machines per 1 m2 will fit into the grow box.

How far apart should the plants be?

The optimal arrangement of marijuana plants on an area of ​​1 m² and the selection of appropriate pots depend on several factors, including the cannabis variety and cultivation technique. Below are some general rules:

  1. Spacing between plants: If we plan to place 4 to 9 plants per 1 m², the ideal spacing between plants should be about 30 to 50 cm. This gives each plant enough space to grow and develop.
  2. Pot size: The choice of pot size depends on the expected size of the plant. For a smaller number of plants (e.g. 4 per 1 m²), you can use larger pots, e.g. with a capacity of 11 to 18 liters. For a larger number of plants (up to 9 per 1 m²), smaller dons will work betterice, e.g. with a capacity of 7 to 11 liters.
  3. Type of flowerpots: You can choose donice plastic, which are light and easy to handle, or donice made of clay, which ensure better air permeability. There are also donice made of fabric that promote healthy root development and prevent overheating.
  4. Space for roots: it is worth making sure that donice provide sufficient space for roots to develop. Limited root space can inhibit plant growth.
  5. Drainage: It's worth choosing donice with good drainage to prevent water accumulation and the risk of root rot.

These tips are general and are best tailored to the specific needs of your own legal grow and your chosen marijuana strains.

The relationship between the size of the tent and the number of cultivated plants, i.e. the cultivation area

growbox appearance

The relationship between the size of the tent and the number of plants grown is crucial for effective and healthy cultivation. Here are examples of arranging plants in grow boxes of various sizes:

  1. Tent 1m x 1m:
    • Ideal number of plants: 4-9, depending on growing technique and variety.
    • Arrangement: Plants can be arranged in even rows, e.g. 2×2, 3×3, depending on their size and the space they need.
  2. Tent 2m x 2m:
    • Ideal number of plants: 8-16.
    • Layout: You can use a 4×4 layout, giving each plant enough space to grow. Alternatively, for smaller varieties, a 5×5 layout is also possible.
  3. Tent 3m x 3m:
    • Ideal number of plants: 18-36.
    • Layout: In this case, a 6×6 layout is suitable for most varieties. For smaller plants, a 7×7 arrangement is possible.

Each plant needs the right amount of space, light and air flow. It is important not to cram too many plants into one tent, which can lead to problems with diseases, pests and limited access to light.

Each tent requires an individual approach, and the choice of the number and arrangement of plants should be adapted to the specific conditions and needs of your crop.

The choice of training method and the number of bushes per 1 m2

Another very important thing when determining - how many machines will fit in the grow box per 1 m2 of cultivation. The use of various training techniques has a significant impact on the number of plants you can grow per 1 m². Here are examples of the number of plants per 1 m² for individual techniques:

  1. Fimming:
    • This technique involves cutting the top of the plant, which stimulates the development of many side shoots. Typically 1-4 plants are grown per square meter when fimming is used, depending on the size and arrangement of the plants.
  2. Sea of ​​Green (SoG):
    • SoG involves growing many small plants instead of a few large ones. You can grow 9-16 plants per 1 m², depending on the size of the pots and the variety of plants.
  3. Toppings:
    • Topping is the removal of the main top, resulting in the development of two main shoots. When using topping, 4-8 plants are usually grown per 1 m², depending on their size and growth form.
  4. Lolipopping:
    • This technique involves removing the lower branches and leaves, which focuses the plant's energy on the upper buds. You can grow about 1-4 plants per 8 m² using lolipopping.
  5. Screen of Green (SCROG):
    • In this techniqueice the plants are trained to grow horizontally under the net. 1-1 plants are usually grown per 4 m², because SCROG allows each plant to grow on a large surface.

These numbers are approximate and may vary depending on variety, growing conditions and plant training experience. It is important to adjust the number of plants to the skills and needs of the crop. Of course, it is impossible to estimate exactly how many machines will fit down to the millimeter per 1 m2 of crops, depending on the training used. A multitude of factors, choice of variety, experience, soil, water, light, diseases, ventilation, pH, electricity, etc. - there are many variables.

How does the ScrOG cultivation technique in a room or grow box affect the number of plants that can be optimally grown per 1 m2?

scrog

How does the use of the ScrOG cultivation technique affect how many machines can fit per 1 m2? Example.

The Screen of Green (ScrOG) growing technique is great for making better use of space in a room or grow box. How does it affect the number of plants that can be grown per 1 m²?

  1. Fewer plants per m²: In techice ScrOG typically uses fewer plants per square meter. It can be assumed that 1 to 1 plants will fit per 4 m². The key factor here is controlling the size and shape of the plants.
  2. Plant training: ScrOG involves training plants to grow horizontally. Plants are gently guided and tied to a horizontal grid, which helps increase photosynthetic efficiency throughout the plant.
  3. Better use of light: By evenly distributing the plants under the light, each part of the plant receives enough light, which increases the overall cultivation efficiency.
  4. Greater yields from individual plants: Although the number of plants per m² is lower, the ScrOG technique can lead to higher yields from each individual plant, thanks to better light exposure and increased bud production.
  5. Greater control over plants: ScrOG allows for better control over the size and shape of plants, which is especially important in the limited space of a grow box.

Remember that each variety reacts differently and the optimal number of plants per m² may vary depending on their type and growing conditions.

Summation

The number of autoflowering marijuana varieties that can be placed per 1 m² depends on several factors, such as the selected cultivation technique, the size and type of plants, and the size of the container. In cultivation indoor, indoors or in a grow box, it is recommended to place 4 to 9 plants per 1 m². This number may vary depending on the size of the plants and the cultivation methods used. With smaller varieties or using the Sea of ​​Green technique, more plants can be placed. With larger varieties and techniques such as Screen of Green, the number of plants will be smaller. It is important to provide plants with enough space, light and airflow to achieve their full growth and flowering potential.
