Growing Marijuana in Small Spaces

Growing Marijuana in Small Spaces

When growing marijuana, the goal is to maximize every inch of space. Some growers are fortunate to have access to an open field, a warehouse, or a greenhouse. However, this is not the case for everyone, which is why men and women need to know how to make the most of the space they do have.

Fortunately, with the right tips and tools, any person can produce a decent marijuana crop with potent buds in even a private and confined grow space. Whether your garden is indoors or outdoors, keeping it small can help you keep this information from you roommates, neighbors, or anyone else you wish to keep in the dark. How can one go about achieving this goal?


When choosing lighting for your marijuana crop, make use of LED lights whenever possible. These lights are compact and won’t take up much space, but they are ideal for growing this plant.

In the past, high-intensity discharge (HID) lights were preferred by growers, as their LED counterparts had some drawbacks. Thanks to the consumer demand for energy-efficient lighting, this is no longer the case. Purchase a high-end LED lighting system and reap the benefits when it comes to your marijuana crop.

LEDs are extremely efficient today and use approximately half the energy of HID systems. In the past, the lights would produce hot spots, but manufacturers have found a way to avoid this issue. Choose the right system and the light will be even over the canopy. Rapid growth and stretching will no longer be an issue in certain growing areas, and the same is true of dead spots.

Additionally, LED systems today are designed to target those portions of the light spectrum that are of most benefit to cannabis plants. As a result, energy is saved, and the quality of the cannabis increases. Finally, these systems come with built-in reflectors. Growers have one less thing to purchase and monitor when this is the case.

Grow Vertical

When you have no floor space, don’t give up your dream of growing marijuana. This crop loves to grow vertically, and some strains do better when this option is selected. In fact, choosing to grow cannabis vertically can actually double the amount of space you have to cultivate the crop.

Simply stack multiple shelves in a hexagon or square and place the light source in the center. When arranged correctly, this setup can provide you with an impressive harvest.

Stack the plants on shelves or arrange them using strings and trellises. Regardless of which option is selected, less space will be needed for growing. As a result, you may be able to add more plants and increase the yield significantly.

One benefit that is often overlooked when this growing method is discussed is the energy savings obtained. Less light is needed to produce the same yield thanks to the central location of the light source. However, this light source must be kept cool.

For this reason, LED lights should be used with vertical growing methods. In addition, a cooling fan under the light source helps to dissipate the heat upward. Be aware that good ventilation is needed when doing this.

Never allow unproductive parts to remain on the plant as it grows. To shape the growth of the cannabis plants, you can string across screens of garden netting to support increased branching of the plant. This technique (also called “ScrOG” for ‘screen of green’) will be of great help. A nice even shape is produced, especially when growing Sativa strains which tend to get quite tall. More on this popular growing technique later on.

Finally, be sure to rotate the crops. This allows each side of the plant to get the same amount of time in front of the central light source.

Use the Right Soil

When growing cannabis outdoors, individuals often have to settle for the soil that is already present. Products can be added to change the quality of the soil to some degree, but this can be costly and time consuming. When growing indoors, this becomes less of an issue.

The soil or grow medium serves as a home for the roots of the plant and allows water and nutrients to reach the necessary areas. When planting small quantities of cannabis, growers want the best harvest possible, and the grow medium plays a large role in whether this is the case.

Complete or super soils are great for this purpose. They contain most of the nutrients the cannabis plant needs. In addition, this type of soil allows the plant to store water so more time can go between waterings.

Monitor the roots so they do not become bound. In addition, make sure they aren’t exposed at any time. If roots began to emerge from the drainage holes found at the bottom of the pot, move the plant to a larger container. If a plant appears to suffer from stunted growth or seems droopy even after being watered, this is often a sign the roots are bound and lacking in the necessary amount of soil.


One thing to be aware of when growing cannabis indoors is the need for adequate ventilation. This becomes increasingly more important the smaller your grow room or tent is.  The fastest way to kill a marijuana crop is to try to grow it in a room that lacks good airflow. When the crop is in a cupboard or closet, an oscillating fan is often enough to provide the necessary ventilation. However, it’s best to situate the plants in a room that includes a built-in fan when possible. Why is this ventilation necessary?

Cannabis plants make their own food using light and CO2. Artificial light is needed when the plants are grown indoors, and these lights produce heat that can be harmful to the plants if not properly dispersed. Furthermore, too much humidity can do harm to a growing crop, and a fan can be of help in dissipating some of the humidity.

Entrance and exit vents are helpful to ensure the plants get fresh, rich CO2 while ensuring depleted CO2 is removed from the growing area. A timer can be of great help in ensuring the room is vented on a consistent basis, so the plants always get what they need.

Some growers choose to invest in a climate control system to maintain the proper CO2 level in the growing space. This is one of several options for ensuring the area is adequately ventilated and that the plants receive the CO2 and light needed to remain fed.


Another thing to consider when growing cannabis indoors is room temperature. Excess heat is damaging to marijuana plants and will decrease the yield of each harvest. Furthermore, some pests harmful to the plants thrive in warm temperatures and breed faster. This can lead to the loss of a crop in little time.

Certain root diseases are more likely to appear when temperatures climb also, and the same is true of foliar diseases. For this reason, every indoor grower needs to make temperature control a priority.

One solution to these common problems is to install an air-cooled lighting system. This helps to lower the temperature in the room considerably. Of course, an air conditioner can be used to achieve the same goal. However, the cost of running an AC for cannabis plants is much higher over time. Keep this in mind when choosing the right solution for your particular situation.


Just as the name suggests, micro-growing is a way to produce cannabis in very small amounts. In fact, a plant can be placed in a kitchen cabinet and produce a decent yield as long as the grower monitors the light, water, and nutrients to ensure the plant is receiving enough of each to meet its needs.

Novice plant aficionados as well as home growers often find they can produce enough cannabis for their personal consumption using this method. Less space is needed, less light and less water, making this the perfect choice for many. Nevertheless, there are some things a person needs to know before buying cannabis seeds to ensure a good harvest.

The first thing to consider is which strain will be grown. Keep in mind the root system of the plant is similar in many ways to the visible portion of the plant. A bushy, short plant will have a bushy root system. A tall, spindly plant, in contrast, will have a root system that mimics the outward appearance. For this reason, the right container must be selected, and this will be discussed more in the upcoming paragraphs.

Use good quality soil that absorbs water, as cannabis plants need a great deal of water to thrive. Adequate ventilation and cooled air are essential here as well along with a light source. Consider making use of a bottom-up watering system to keep the plant hydrated without drowning it.

Container Size

As mentioned above, the root system of a cannabis plant closely mimics the outward appearance of the plant. Keep this in mind when choosing a strain to grow. Selecting the right container is essential to ensure the best yield as well. However, this is where many growers struggle.

To determine which pot size to purchase, use the following guidelines. For a plant that stands 60 centimeters high, a five-liter pot should be adequate. Larger plants benefit from a 12-liter pot and a 24cm plant would do fine in a pot that is between two and three liters. For a small plant, one standing 13cm high, a .5 liter pot should be enough.

The container is of great importance. When a plant is placed in a pot that is too small, the roots outgrow the space and the plant becomes root bound. This means too many roots have been created and there is no longer enough space for the soil, nutrients, and water.

A micro-grow setting leads to the plant needing more food and fertilizer. Be sure to know which fertilizer is best for the strain being cultivated and how much should be applied. This ensures the plant does not get too much of a good thing. Keep this in mind when choosing a container and take the space where the container will be placed into account as well.

Use the SCROG Method

One way to maximize your crop when growing in a small space is to use the SCROG method. When this technique is employed, the plants grow neat and tidy. Branches remain under control, and there is no concern of them crowding each other out. What exactly is this method and how can you put it into practice?

SCROG stands for “Screen of Green” and is a method that optimizes the light source by bringing the lower buds closer to the canopy top. Thanks to the better light distribution, higher yields may be obtained. The plants are bushier and use the available space efficiently.

This method is actually nothing more than training the plants to grow a certain way. A screen is secured above the canopy, and the plants are tied onto the screen as they grow. However, there are additional steps to be taken to ensure the best crop.

In addition to tying the plants to the screen, the tops of the plants should be cut off. This helps the plant grow outward rather than upward. More branches will sprout when this is the case, and the plant becomes bushier. More of the branches and leaves are exposed to the light source also, making this an efficient use of the available space.

Choose the Right Strain

Growers often turn to an Indica strain rather than a Sativa strain when trying to get the most out of a small grow space. This is due to the size difference between the two. Indica strains typically are short and stocky and grow close to the ground. Although Sativa strains can be grown indoors, the results are often less than ideal.

Nevertheless, this is a general observation. Certain Indica strains grow tall while some Sativa strains remain short. Know the different strains and the characteristics of each to ensure you get the right seed for your needs.

Another option to look into is auto-flowering cannabis. This type of plant flowers when it reaches a certain age as opposed to when the light changes. These plants tend to be short and small as well.

A Clean Environment

Don’t assume the plants can be shoved in a dirty closet and still do well. The environment needs to be clean to produce a healthy crop, especially in a small grow space. This is one reason why ventilation is so necessary. A damp environment can lead to mold growth and allow plant diseases to thrive. Keep the growing area as clean as possible at all times to avoid problems such as these.
