2.1 Basics for your cannabis plants

Equipment for growing cannabis

Growing cannabis requires careful planning and the right equipment to create optimal growing conditions. Here's a list of the essential equipment you'll need for a successful grow:

1. Lighting

  • LED lamps : Energy efficient and generate little heat.
  • HPS lamps (high-pressure sodium lamps) : Are increasingly being replaced by LED lamps because they are more efficient and consume less electricity.
  • CFL lamps (compact fluorescent lamps) : Good for smaller growing areas or the seedling phase.

2. Grow tent or grow room

  • Grow tent : Provides a controlled environment and is available in various sizes.
  • Reflective walls : Increase light output and improve plant growth.

3. Ventilation

  • Exhaust fan : Removes excess heat and moisture.
  • Circulation fans : Ensure even air circulation within the grow tent.
  • Activated carbon filter : Neutralizes odors and cleans the exhaust air.

4. Irrigation system

  • Watering can or spray bottle : For manual watering.
  • Automatic irrigation system : Drip irrigation or hydroponic systems for larger growing projects.

5. Nutrients and fertilizers

  • Base fertilizer : Special nutrient solutions for the growing and flowering phases. There are mineral and organic fertilizers. Organic fertilizers are more difficult to apply because deficiencies or overfertilization are only noticeable later.
  • Additives : Micronutrients such as calcium, magnesium and iron.

6. Substrat

  • Soil : High-quality, well-drained soil with organic matter.
  • Hydroponic media : coconut fiber, rock wool or perlite.

7. Pots and containers

  • Plant pots : In different sizes depending on the growth stage of the plant.
  • Fabric pots (Smart Pots) : Promote root aeration and prevent root binding.

8. Measuring instruments

  • pH meter : For checking the pH value of water and nutrient solutions.
  • EC meter (electrical conductivity) : Measures the concentration of nutrients in the water.
  • Thermometer/Hygrometer : Monitors temperature and humidity in the grow room.

9. Other equipment

  • Timers : Automate light cycles and watering times.
  • Scissors and trimmers : For pruning and harvesting plants.
  • Magnifying glasses or microscopes : For detailed examination of trichomes during the flowering phase.

With this equipment, you'll be well-equipped to grow your cannabis plants under optimal conditions. Make sure to check and maintain your equipment regularly to ensure healthy growth.

What cannabis plants need

Cannabis plants are robust and adaptable plants, but they require specific conditions to thrive. Here are the key factors to consider:

1. Light

  • Sunlight : Outdoors, cannabis plants need at least 6 hours of direct sunlight per day.
  • Artificial light : LED, HPS, or CFL lamps are commonly used for indoor cultivation. The lighting duration varies depending on the growth phase (18 hours of light during the vegetative phase, 12 hours during the flowering phase).

2. Water

  • Watering : Regular watering is crucial, but waterlogging should be avoided. The soil should be moist but not soggy.
  • pH : The ideal pH of water is between 6.0 and 7.0 for soil cultivation and between 5.5 and 6.5 for hydroponics.

3. Nutrients

  • Macronutrients : Nitrogen (N), phosphorus (P), and potassium (K) are the main nutrients. More nitrogen is needed during the vegetative phase, and more phosphorus and potassium are needed during the flowering phase.
  • Micronutrients : Calcium, magnesium and iron are also important for healthy growth.

4. Air circulation

  • Fresh air : Good ventilation is necessary to prevent mold growth and provide CO₂ for photosynthesis.
  • Ventilation : Fans can help improve air circulation and regulate temperature and humidity.

5. Temperature

  • Optimal temperatures : During the day, temperatures should be between 21°C and 26°C; at night they should not fall below 16°C.
  • Temperature fluctuations : Large fluctuations between day and night temperatures should be avoided.

6. Humidity

  • Humidity : During the seedling phase, a high humidity of around 70% is ideal. During the vegetative phase, it should be around 50–60%, and lowered to around 40–50% during the flowering phase.

7. Soil or substrate

  • Soil : A well-drained soil with a high content of organic matter is ideal.
  • Hydroponics : Alternatively, substrates such as coconut fibers or rock wool can be used.

8th place

  • Root space : Adequate space for root growth is crucial for healthy plants.
  • Distance between plants : Sufficient distance ensures that each plant gets enough light and air.

By meeting these basic needs of your cannabis plants, you'll lay the foundation for a successful harvest. Make sure to regularly monitor your plants and address their specific needs – this way, nothing will stand in the way of a successful growing season!
