2. Basic cultivation requirements
Growing cannabis requires a certain amount of knowledge and preparation to ensure healthy plants and a good harvest. Here are the basic requirements you should keep in mind when growing cannabis:
Light requirements
Light is one of the most important components for the growth of cannabis plants. They require a sufficient amount of light to perform photosynthesis and grow healthily. Most growers use special grow lights such as LED or HID lights. These provide the right spectrum and intensity of light that cannabis plants need.
- Vegetation phase: 18 hours light, 6 hours darkness
- Flowering phase: 12 hours light, 12 hours darkness
You can find out more about the right lighting in the chapterlighting.
Water requirements
Water is also essential for the growth of cannabis plants. Proper watering can make the difference between a healthy plant and a stressed one. Make sure the soil is always moist, but not soggy. Overwatering can lead to root rot, while underwatering will dry out the plant.
- Use pH-neutral water (pH 6.0 to 7.0)
- Make sure excess water can drain away
Further details on watering and care can be found in the chapterPour.
Nutrient requirements
Cannabis plants require a balanced supply of nutrients to grow optimally. The most important macronutrients are nitrogen (N), phosphorus (P) and potassium (K), often given as an NPK ratio. In addition to these, they also need micronutrients such as calcium, magnesium and sulfur.
- Vegetation phase: High nitrogen requirement
- Flowering phase: Higher need for phosphorus and potassium
You can learn more about the right nutrients in the chapterThe function of nutrients.
Temperature and humidity
Controlling temperature and humidity is crucial for the well-being of your plants. During the vegetative phase, the ideal temperature is between 20 and 28 degrees Celsius, and during the flowering phase, between 18 and 26 degrees Celsius. Humidity should be between 40% and 70% during the vegetative phase and reduced to 40% to 50% during the flowering phase.
- Vegetation phase: 20-28°C, 40-70% humidity
- Flowering phase: 18-26°C, 40-50% humidity
For more information on controlling temperature and humidity, see the chapterTemperature and humidity.
Cultivation locations and methods
The growing location and method you choose will also affect the success of your grow. Indoor growing gives you the opportunity to better control environmental conditions, while outdoor growing makes use of natural resources such as sunlight and rainwater.
You can find out more about the different cultivation methods in the chapterCultivation locations and methods.
By following these basic growing requirements, you will lay the foundation for successful cannabis cultivation. You can find more detailed instructions and tips in the relevant chapters of our grow guide.
3. The growth phases of the cannabis plant
To successfully grow cannabis, it is important to understand the different growth phases of the plant. Each phase has specific requirements and needs that must be taken into account in order to cultivate healthy and productive plants.
germination
Germination is the first step in the life cycle of the cannabis plant. During this phase, the seed develops into a seedling. It is crucial that the seeds germinate in a moist and warm environment.
- Temperature: 20-25°C
- Humidity: 70-90%
Light: Darkness until the seedlings appear
Further details on germination can be found in the chapterSeeds germinate.
Seedling phase
In the seedling phase, the seedling develops its first leaves and roots. This phase lasts about two to three weeks. High humidity and constant temperature are important to promote growth.
- Temperature: 20-25°C
- Humidity: 60-70%
- Light: 18-24 hours of light per day
You can learn more about this phase in the chapterCannabis seedlings.
Growing period
During the growing season, the plant grows vigorously and develops many leaves and stems. This phase can last several weeks to months, depending on the desired plant height and size.
- Temperature: 20-28°C
- Humidity: 40-70%
- Light: 18 hours light, 6 hours darkness
- Nutrients: High nitrogen requirement
For more information about the growing season, see the chapterGrowing period.
Flowering phase
The flowering phase is the last growth phase and begins when the light hours are reduced. During this phase, the plant produces flowers and resin. The flowering phase usually lasts 6-10 weeks, depending on the variety.
- Temperature: 18-26°C
- Humidity: 40-50%
- Light: 12 hours light, 12 hours darkness
- Nutrients: Higher need for phosphorus and potassium
You can learn more about the flowering phase in the chapterFlowering phase.
4. Important terms and concepts in cannabis cultivation
When growing cannabis, there are a variety of terms and concepts you should know in order to be successful. Here are some of the most important:
THC and CBD
THC (tetrahydrocannabinol) and CBD (cannabidiol) are two of the most well-known cannabinoids found in cannabis plants. THC is psychoactive and responsible for the "high" feeling, while CBD is non-psychoactive and is valued for its medicinal properties.
- THC:Psychoactive cannabinoid found mainly inSativa and Indica strainsoccurs.
- CBD:Non-psychoactive cannabinoid often used in medical cannabis products.
Photoperiod
Photoperiod refers to the daily light-dark period that cannabis plants receive. It plays a crucial role in the plant's life cycle, influencing growth and flowering.
- Vegetation phase:18 hours light, 6 hours darkness
- Flowering phase:12 hours of light, 12 hours of darkness
For more information about the photoperiod, see the chapterlighting.
Autoflowering vs. Photoperiod Plants
There are two main types of cannabis plants: autoflowering and photoperiod plants. Autoflowering plants start flowering automatically, regardless of the light-dark time, while photoperiod plants require a change in light conditions to enter the flowering phase.
Indica, Sativa and Hybrids
There are three main categories of cannabis strains: Indica, Sativa and Hybrids. Each has unique characteristics and effects:
- Indicas:Known for its relaxing and calming effects, ideal for evening use.
- Cannabis:Known for its invigorating and cerebral effects, ideal for daytime use.
- Hybrids:A blend of Indica and Sativa genetics that offers a combination of the characteristics of both species.
You can learn more about the different varieties in the chapterCannabis strains.
Feminized seeds
Feminized seeds are bred to produce almost exclusively female plants. This is important because only female plants produce flowers that contain the desired cannabinoids.
- Reduces the likelihood of male plants
- Increases efficiency and yield
Regular seeds
Regular seeds can produce both male and female plants. They are often cheaper than feminized seeds, but require more effort as male plants must be removed to prevent pollination of the female plants.
- Requires identification and removal of male plants
- Useful for breeding projects
For further details on choosing the right seed, see the chapterChoosing the right seed.
Sativa, Indica and Ruderalis
Cannabis sativa, Cannabis indica and Cannabis ruderalis are the three main types of the cannabis plant. Sativa and Indica are the most well-known and commonly cultivated, while Ruderalis is often used in breeding programs due to its autoflowering properties.
- Cannabis:Tall, slender plants with long, narrow leaves.
- Indicas:Short, bushy plants with broad leaves.
- Ruderalis:Small, robust plants that flower quickly.
By understanding these important terms and concepts, you will lay a solid foundation for your successful cannabis cultivation. Use the other chapters of our grow guide to get detailed instructions and tips to help you achieve your growing goals.
