Pruning Techniques for Cannabis Plants
Pruning selectively removes unnecessary foliage, redirecting the plant’s energy into producing larger, denser, higher-quality buds. It also improves plant morphology, resulting in a better microclimate by increasing light exposure and air circulation around the plant.Cannabis exhibits monopodial growth, meaning it develops a single main stem that grows vertically, and because it is apically dominant,[1] the main stem inhibits the growth of lateral shoots. Pruning the main stem relieves the plant of apical dominance, triggering hormonal changes—specifically, changes in auxin and …

Canopy Lighting in Cannabis Cultivation
One of the biggest challenges for indoor cannabis growers is replicating the sun’s ability to penetrate the plant canopy, particularly the lower portions. Outdoors, photons[1] from natural sunlight strike leaf surfaces at multiple angles throughout the day, ensuring light distribution throughout the plant. By contrast, traditional overhead lighting in indoor cultivation struggles to reach the lower canopy, limiting photosynthesis and yields. To remedy this problem, canopy lighting has emerged as an effective method for ensuring all parts of the plant receive adequate …

Choosing a Hydroponic System
Hydroponics is a soilless growing method where plants receive a water-based nutrient solution,[1] giving growers precise control over the growing environment and inputs like water, nutrients and oxygen. Several hydroponic systems—varying in size, complexity and efficiency—are available. These setups can be: Open or closed: Open systems discharge the nutrient solution after use. Closed systems recirculate the nutrient solution for reuse. Active or passive: Active systems use pumps to deliver the nutrient solution to plants. Passive (e.g., wick) systems give roots …

Optimizing pH in Hydroponics
The acidity or alkalinity of a liquid is measured as pH. A low pH indicates high acidity, while a high pH indicates high alkalinity. More concretely, pH—short for “potential of hydrogen”—reflects the concentration of hydrogen ions. When acids dissolve in water, they release H+ ions, lowering the pH. Bases release OH- ions, raising the pH. The pH scale ranges from 0 to 14, with 7 being neutral (Figure 1). Figure 1. pH scale. Acidic solutions have a low pH. Alkaline solutions have a high pH. Neutral …
