Best CBD Cultivation: Indoor vs Outdoor vs Greenhouse

Legal cultivation of CBD cannabis

Knowing the differences between indoor vs. outdoor vs. greenhouse cultivation is interesting not only for those who are new to the world of cannabis cultivation, but also for those users who are looking to to buy CBD online .

In this post we talk about the differences between these cultivation methods, how it can influence the characteristics of the final product and what is the best type of cultivation.

Key differences between indoor, outdoor and greenhouse cannabis cultivation

The fundamental difference between indoor and outdoor CBD cultivation is the exposure to environmental conditions of light, temperature and humidity, as well as possible inclement weather.

As for the cultivation of cannabis greenhouse or greenhouse, is considered an intermediate type of cultivation, since it allows benefiting from some conditions of outdoor cultivation, such as natural light, and from optimizations typical of indoor cultivation, such as artificial light support or a greater control of environmental conditions, compared to outdoor cultivation.

All this results in differences in growing conditions and in the cost of infrastructure, maintenance and production. Furthermore, depending on the type of crop, the quality of the final product is also affected.

What type of cultivation is best for cannabis?

In reality, it is not always possible to generalize the differences between one type of cultivation and another, but the final result ultimately depends on each particular case. The knowledge and technique of the grower, the genetics of the seed and the drying and curing process of the cannabis are decisive factors in the quality of the final product. Having contextualized this point, let’s look at the basic differences of each type of cultivation on the quality of cannabis.

Comparison: Cannabis Indoor vs. Outdoor vs. Greenhouse


In general, growing cannabis indoors allows a more optimal control of the growing conditions. This results in an ideal environment to maximize the production of active components such as THC, CBD and other cannabinoids. By having complete control over factors such as light, temperature, humidity and nutrition of cannabis plants, growers can adjust these variables to favor the development of buds with high concentrations of resin, including cannabinoids and terpenes.

In addition, growing in a closed environment provides greater control over possible infestations and diseases, as well as the possibility of achieving exceptional uniformity in the final product. This cultivation approach is the preferred choice of the most demanding consumers in search of specific quality and consistency.

On the other hand, greenhouse cultivation can be considered a balanced mix between indoor and outdoor cultivation. In the protected environment of a greenhouse, plants are sheltered from rain and wind, while taking advantage of sunlight to optimize photosynthesis and facilitate precise temperature control.

The management of a greenhouse crop can vary widely depending on the level of infrastructure technology. Greenhouses can range from simple plastic tunnels mounted on structures, to large glass structures known as glasshouses, which can reach up to 8 meters high and be equipped with state-of-the-art technology, including irrigation systems, artificial lighting and advanced climate control.

In contrast, outdoor cultivation is the lowest cost option, although with greater exposure to pests and diseases. Plants are usually grown directly in the soil rather than in pots. Soil quality, nutrient availability and microbial life play an essential role in obtaining high quality, fragrant flowers in outdoor cannabis cultivation.

Cannabis grown outdoors can have unique nuances in aroma and flavor, influenced by soil composition and soil conditions, similar to how wine gets its distinctive character from its specific terroir.

The aroma of cannabis is determined by its terpene content. We must not forget that these compounds are like natural defenses used by the plant to protect itself from adversities, such as pests or adverse weather conditions.

In the cannabis consumer, the effects of terpenes are very different. These aromatic compounds can provoke or increase feelings of relaxation, sedation or euphoria, in synergy with cannabinoids, contributing to the so-called indica or sativa effect of cannabis.

Can the same seed produce different terpenes indoor / outdoor?

Broadly speaking, the terpene profile of a cannabis strain is mainly determined by its genetic code. Generally speaking, the terpene profile will be consistent, whether the seed is grown indoors or outdoors, as long as it is the same genetic variety.

The key to achieving maximum genetic expression of both terpenes and cannabinoids, regardless of the growing environment, lies in the management of the crop itself.

The intensity of the “high” that a cannabis strain produces generally does not depend on the type of cultivation (indoor, outdoor or greenhouse).

What really influences the potency of the effect is the interaction between the cannabinoid profile of the strain, the terpenes and flavonoids present, as well as how these components interact with each individual’s endocannabinoid system and personal tolerance to cannabis use. Therefore, it is more important to consider the chemical composition of the variety and how it suits the consumer’s needs and preferences than the growing method itself.


Again, the color of a cannabis strain depends on a number of different factors, including genetics, crop management, temperature and others.

In general, plants grown indoors tend to exhibit more vibrant colors, while plants grown outdoors or in greenhouses may develop darker shades of green and brown due to sun exposure.

The post-harvest process also plays a crucial role, as drying the flowers in a cool environment helps to maintain their color, while drying in a warm place accelerates oxidation and can result in darker shades.

The purple and red colors often associated with certain cannabis strains (such as purple marijuana or Purple Haze) are influenced by both the genetics of the plant and other factors, such as exposure to cold during the last weeks of flowering.

The color of cannabis is also influenced by the genetics of the seed. At the genetic level, some varieties have the ability to produce pigments called anthocyanins, which provide these distinctive colors and are also found in other agricultural species, such as blueberries. The appearance of these pigments is related to edaphoclimatic factors, such as temperature, soil pH and type of light.

Differences in flower size

In indoor cultivation, where environmental conditions are highly controlled, plants tend to be smaller and more compact. This is because factors such as the height of the lights, the distance between plants and the duration of the light can be adjusted, which encourages more controlled growth.

The difference in the size of cannabis plants depends largely on the type of cultivation used: indoor, outdoor or greenhouse:

On the other hand, in outdoor cultivation, plants have the opportunity to grow more naturally and, as a result, tend to be larger and more robust. Access to direct sunlight and available space allow plants to reach their maximum growth potential.

Greenhouse cultivation is at an intermediate point in terms of size. Greenhouse plants can be larger than indoor plants due to the exposure to sunlight, but smaller than outdoor plants due to the moderation of environmental conditions.

Ultimately, the size of cannabis plants is influenced by a combination of genetic factors, growing conditions and management. Each type of crop offers unique advantages and challenges in terms of plant size control and ultimately affects crop quantity and quality.

The Quality Debate: Is indoor, outdoor or greenhouse cannabis better?

The debate about the quality of cannabis between indoor, outdoor and greenhouse cultivation is a complex and subjective issue that depends on several factors. Each type of crop has its own advantages and disadvantages in terms of quality, and the choice of the “best” ultimately depends on consumer preferences and farming approach. Even within the same type of cultivation it is possible to appreciate varieties of cannabis with notable distinctive characteristics and traits.

In short, the cannabis plant is extraordinary, and its diversity makes it difficult to generalize about it, since from seed to post-harvest, including the type of cultivation, there are numerous factors that intervene in the quality of the final result. Moreover, cannabis is not just a plant; it is an experience, in which we each feel slightly different sensations and preferences, even depending on the day.
