Blended spectrum cannabis” typically refers to cannabis plants grown under lighting systems that provide a combination of different light wavelengths, mimicking the natural spectrum of sunlight. This approach is common in indoor cannabis cultivation, where artificial lighting is used to support plant growth and flowering.
Blended spectrum lighting systems often combine light-emitting diodes (LEDs) that emit various wavelengths, including blue, red, white, and sometimes far-red light. By blending these different wavelengths, growers aim to provide cannabis plants with the full spectrum of light they need for optimal growth, health, and cannabinoid/terpene production throughout their life cycle.
The use of blended spectrum lighting in cannabis cultivation is based on the understanding that different light wavelengths influence different aspects of plant physiology. For example:
- Blue light: Promotes vegetative growth, helps regulate plant size, and influences leaf development and photosynthesis.
- Red light: Stimulates flowering and fruiting processes, promotes bud development, and contributes to resin production.
- White light: Provides overall illumination and supports balanced growth across various plant tissues.
- Far-red light: Plays a role in plant development and flowering regulation, particularly during the transition from vegetative to flowering stages.
By providing a balanced spectrum of light, blended spectrum cannabis cultivation aims to optimize plant health, growth, and yield, as well as the production of cannabinoids (such as THC and CBD) and terpenes. Additionally, using adjustable blended spectrum lighting systems allows growers to customize light settings according to the specific needs of different cannabis strains and growth stages, maximizing overall crop quality and yield.
