PAR And Cannabis Grow Lighting

PAR stands for Photosynthetically Active Radiation, which refers to the wavelengths of light that are essential for photosynthesis in plants. PAR is a range of light wavelengths between 400 and 700 nanometers (nm), which includes blue (400-500nm) and red (600-700nm) light.

In cannabis growing, PAR is an important consideration because it represents the wavelengths of light that are most effective for promoting plant growth and yield. Plants absorb light energy in the PAR range to fuel photosynthesis, which is the process by which plants convert light energy into chemical energy that they can use for growth.

When growing cannabis, it is essential to provide adequate PAR to the plants to ensure optimal growth and yield. High-quality grow lights with a balanced spectrum of PAR are important for indoor growers, as natural sunlight may not be sufficient to provide the necessary amount of PAR for cannabis plants.

Growers can select grow lights that provide specific PAR ranges based on the stage of plant growth. For example, during the vegetative stage, cannabis plants benefit from higher levels of blue light, while during the flowering stage, plants require more red light. By adjusting the PAR spectrum and intensity of the grow lights, growers can promote optimal growth and maximise yield.

In summary, PAR is a range of wavelengths of light between 400 and 700 nm that is essential for photosynthesis in plants. In cannabis growing, providing adequate PAR to the plants is crucial for optimal growth and yield. Growers can select grow lights that provide specific PAR ranges based on the stage of plant growth and adjust the spectrum and intensity of the lights to promote healthy plant growth and high yield.
