Proper lighting is a crucial factor for success in cannabis cultivation. The light spectrum plays a central role as it directly influences the growth and development of the plants. Here are the most important points you should know: The optimal light spectrum for different growth phases 1. Seedling and vegetative phase Blue light (400–450 nm): Promotes the development of strong roots, stems and leaves. Recommended light source: LED lamps with a high proportion of blue light. 2nd flowering phase Red light (620–660 nm): Increases flower formation and photosynthesis. A small amount of blue light maintains plant stability. 3. Late phase...

Defoliation of cannabis is an important technique that optimizes growth, improves light distribution, and allows for a better harvest. It increases the quality and quantity of flowers when done correctly. This method offers benefits such as improved light penetration, better air circulation, and targeted energy redirection. Key times for defoliation are the vegetative phase to shape the plant and the flowering phase after the stretch phase to encourage flower production. The technique involves removing large fan leaves that shade lower flowers and retaining sufficient foliage for photosynthesis. Tips for beginners include observing the plants, being patient during the recovery period,...

Potassium deficiency is a common problem in cannabis cultivation that can severely affect plant health and yields. Typical symptoms include yellow or burnt leaf edges (marginal necrosis), dark spots, curling leaves, and stunted growth. Main causes are: An incorrect pH value that blocks potassium absorption. Nutrient blockage due to excess of other minerals. Incorrect or unbalanced fertilization. overwatering. Treatment options: Check and adjust the pH value (optimal: 6.0–7.0 for soil, 5.5–6.5 for hydroponics). Use appropriate potassium supplements or balanced fertilizers. Flush the medium if nutrient blockage occurs. Avoid waterlogging and improve drainage. Prevention: Regular pH and EC checks and the...

Harvesting cannabis flowers marks the climax of the cultivation process. Two key indicators, trichomes and pistils, help determine the optimal time to harvest. Careful preparation, such as cleaning tools and setting up a clean work area, is essential. Depending on your space and preference, you can cut the whole plant or individual branches. Trimming the leaves is done either wet for faster drying or dry to preserve more trichomes. After harvesting, drying and curing under ideal conditions ensures the best aroma and full potency of the flowers. Attention to detail throughout the harvest guarantees a high-quality end product that home...
