The 5 most important requirements for your cannabis cultivation

Before you dive into the fascinating world of cannabis cultivation, you need to create some basic conditions. These 5 factors are crucial to your success and form the foundation for healthy, productive plants.

1. The right location

Choose a discreet, well-ventilated room with a stable temperature. Ideally, it should be between 20-28°C and free from mold. A tent or converted closet is perfect for beginners. Remember: the larger the room, the more control you will need over environmental factors.

2. High-quality equipment

Invest in good equipment - it pays off! High-quality LED grow lamps, a reliable ventilation system and precise measuring devices for pH and humidity are essential. Don't skimp in the wrong place, because good equipment is the key to healthy plants and a rich harvest.

3. Nutrients and substrates

Your cannabis plants need the right nutrients in every growth phase. Choose a high-quality substrate and find out about the specific needs of your variety. A balanced NPK fertilizer (nitrogen, phosphorus, potassium) forms the basis for healthy growth.

4. Genetics and varieties

Choosing the right genetics is crucial. For beginners, robust, autoflowering strains are recommended. They are less prone to failure and have a shorter life cycle. Do your research on different strains and their characteristics before making a decision.

5. Legal basis

Last but by no means least important point: find out about the legal situation in your country or state. In many regions, private cultivation of cannabis is still illegal. Make sure you act within the law to avoid unpleasant surprises.

With these 5 basic requirements, you will lay the foundation for your successful cannabis cultivation. Prepare thoroughly, be patient and learn from your experiences. Over time, you will develop a feel for the needs of your plants and be able to enjoy magnificent, aromatic flowers.

Seeds or clones? Choose the perfect starting method

One of the first big decisions you'll have to make as a budding cannabis grower is choosing between seeds and cloning. Both methods have their pros and cons that you should carefully consider.

Benefits of Cannabis Seeds

Seeds offer you greater genetic diversity and the opportunity to grow rare or exotic varieties. They tend to be more robust and develop a stronger root system. They are often a better choice for beginners as they are easier to obtain and store.

Disadvantages of seeds

The disadvantage: You cannot be sure whether you are getting male or female plants. Male plants have to be sorted out because they do not produce usable flowers. In addition, growing from seeds takes a little longer than with clones.

Advantages of cloning

Clones are genetically identical copies of a mother plant, so you know exactly what you're getting - guaranteed female plants with known characteristics. They tend to grow faster and flower earlier than seed plants.

Disadvantages of cloning

However, clones are more susceptible to diseases and pests. They often develop a weaker root system and are more sensitive to environmental influences. In addition, it is often more difficult for beginners to obtain high-quality clones.

criterion	Seeds	Clones
Genetic diversity	High	Small amount
Sex determination	Unsure	Definitely female
Growth period	Longer	Shorter
robustness	Higher	Low

For your first grow project, I recommend starting with seeds. They are more forgiving of beginner mistakes and give you the opportunity to observe the entire life cycle of the plant. Choose feminized seeds to increase the likelihood of female plants.

Whatever your choice, it's important to take good care of your plants from the start. Observe them closely, adjust environmental conditions, and respond quickly to signs of stress or disease. Over time, you'll develop a feel for which method works best for you and your growing conditions.

Nutrients and substrates: the key to lush growth

An optimal supply of nutrients and the right substrate are crucial for healthy, productive cannabis plants. With the right knowledge, you can give your plants exactly what they need in every growth phase.

Choosing the ideal substrate

Your substrate forms the basis for healthy growth. It should be airy and permeable to water, but also be able to store moisture. For beginners, a pre-fertilized, high-quality potting soil or special cannabis soil is suitable. Advanced growers often experiment with coconut, rock wool or hydroponic systems.

When choosing a substrate, pay attention to the following properties:

• Good drainage and ventilation
• pH between 6.0 and 6.5 for soil (5.5 to 6.0 for hydro)
• Balanced nutrient content
• Free from pests and pathogens

Essential nutrients for cannabis

Cannabis requires a variety of nutrients, with the main nutrients nitrogen (N), phosphorus (P) and potassium (K) being particularly important. The optimal ratio of these nutrients changes over the course of the growth cycle:

Growth phase	Nutrient ratio (NPK)
Vegetative phase	Higher nitrogen content (e.g. 5-2-3)
Flowering phase	More phosphorus and potassium (e.g. 2-8-4)

In addition to NPK, micronutrients such as calcium, magnesium, iron and zinc are also important. Many special cannabis fertilizers already contain a balanced mixture of all the necessary nutrients.

Fertilize correctly - less is often more

Over-fertilizing is a common beginner's mistake. Start with about half the recommended dose and increase slowly. Watch your plants closely for signs of nutrient deficiency or excess. Yellowing leaves can indicate nitrogen deficiency, while burnt leaf tips are often a sign of over-fertilization.

Pay attention to pH value and water hardness

The pH of your substrate and water significantly affects nutrient uptake. Keep the pH in the range of 6.0 to 6.5 for soil and 5.5 to 6.0 for hydroponic systems. Use pH test strips or a digital pH meter to check.

Water hardness also plays a role. Water that is too hard can change the pH value and impair nutrient absorption. If the water is very hard, you should consider using a water filter or distilled water.

With the right combination of high-quality substrate and appropriate fertilization, you lay the foundation for healthy, strong cannabis plants. Experiment carefully and learn from your experiences. Over time, you will develop a feeling for what your plants need to reach their full potential.

Lighting and ventilation: Optimize your grow setup

Lighting and ventilation are crucial factors for a successful cannabis grow project. They not only influence growth and flowering, but also the health of your plants.

Choosing the right lighting

Cannabis needs a lot of light to grow and flower optimally. There are several lighting options available for indoor cultivation:

• LED grow lamps: energy efficient, low heat emission, long lifespan
• HPS lamps (high-pressure sodium lamps): high light output, proven technology
• MH lamps (metal halide lamps): Good for the vegetative phase
• Fluorescent tubes: Suitable for cuttings and young plants

For beginners, I recommend LED grow lights. They offer a balanced spectrum, are easy to use, and use less energy. Look for a power output of around 50-80 watts per square foot of growing space.

Light cycles and photoperiod

Cannabis is sensitive to light cycles. During the vegetative phase, plants need 18-24 hours of light per day. To initiate flowering, switch to a 12/12 cycle (12 hours of light, 12 hours of darkness). Autoflowering strains are less sensitive to light and can receive 18-20 hours of light continuously.

Growth phase	Light cycle
Vegetative phase	18-24 hours light / 0-6 hours darkness
Flowering phase	12 hours light / 12 hours darkness

Ventilation and air circulation

Good ventilation is just as important as the right lighting. It helps regulate temperature and humidity and prevents mold growth. An effective ventilation system consists of several components:

• Exhaust fan: Removes warm, humid air
• Air inlet: Allows fresh air to flow in
• Oscillating fans: ensure air movement between the plants
• Activated carbon filter: Reduces odors (optional but recommended)

Make sure your fans are powerful enough to completely change the air volume of your grow room every 1-3 minutes. This will help keep the temperature stable and prevent the buildup of moisture.

Control temperature and humidity

Cannabis thrives best at temperatures between 20-28°C and a relative humidity of 40-60%. During the flowering phase, you should lower the humidity to 40-50% to prevent mold growth. Invest in a good thermo-hygrometer to be able to constantly monitor these values.

If the temperature is too high, you can use additional ventilation or move your lighting further away from the plants. If the humidity is too low, a humidifier will help, while a dehumidifier can be used if the humidity is too high.

Odor control

Cannabis plants can smell strong, especially during the flowering phase. An activated carbon filter in your ventilation system can effectively neutralize these odors. Be sure to change the filter regularly to maintain its effectiveness.

With the right combination of lighting and ventilation, you can create optimal conditions for your cannabis plants. Experiment carefully and adjust your setup until you find the perfect balance. Remember: a well-thought-out grow setup is the key to healthy plants and a rich harvest.

From Germination to Harvest: The Ultimate Timetable for Beginners

Growing cannabis is an exciting journey that requires patience and care. This timeline will give you an overview of the most important stages and milestones, from germination to harvest. Note that the exact time frames may vary depending on the strain and cultivation method.

Week 1-2: Germination and seedling stage

Your cannabis journey begins with germination. Place the seeds between damp paper towels or directly into a growing medium. After 24-72 hours, the first roots should be visible. As soon as the seedlings appear, place them under low light. Keep the environment moist and warm (around 20-25°C). During this phase, the plants need 18-24 hours of light daily.

Week 3-6: Vegetative phase

Now the vegetative growth begins. The plants develop strong stems and leaves. Slowly increase the light intensity and start with light fertilization. The light cycle remains at 18-24 hours of light per day. Towards the end of this phase you can start training the plants, e.g. through Low Stress Training (LST), to make the best use of the growing area.

Week	Main tasks
3-4	Repotting into larger containers, beginning light fertilization
5-6	Plant pruning/training, increasing nutrient levels

Week 7-10: Pre-flowering and sex determination

At around week 7, you can change the light cycle to 12/12 hours to induce flowering. In the following days, the plants will show their gender. Remove all male plants to prevent pollination. The plants will grow quickly now, so good ventilation is important. Adjust the nutrient supply to the flowering phase.

Week 11-15: Main flowering phase

This is the most exciting phase. The plants are now developing their characteristic flowers. Pay particular attention to the humidity to avoid mold growth. The nutrient requirements are changing: more phosphorus and potassium, less nitrogen. Watch your plants closely for signs of nutrient deficiencies or pest infestation.

Week 16-18: Ripening and harvest

In the last few weeks before harvest, the trichomes (resin glands) begin to mature. Observe them with a magnifying glass: when they turn from clear to milky white and finally amber, it is harvest time. About a week before the planned harvest, start flushing the plants with only clear water to wash out any remaining nutrients.

To harvest, cut the plants and hang them upside down to dry. This takes about 7-14 days. Then cure in airtight jars for at least 2-4 weeks to optimize flavor and potency.

Important tips for the entire cultivation cycle:

• Keep a grow journal to learn from your experiences.
• Monitor temperature and humidity continuously.
• Be patient and avoid over-intervention.
• Find out about the specific needs of your chosen variety.
• Prepare for the next phase in good time.

Remember that every grow cycle is unique. Over time, you will develop a feel for what your plants need. Enjoy the process, learn from your experiences and look forward to a bountiful, home-grown harvest!
