Enhancing Cannabis Flowering with Deep Red Supplemental Lighting: A Comprehensive Guide
The cultivation of cannabis has become increasingly popular in recent years, with enthusiasts and professional growers alike striving to optimise their plants’ growth and potency. One of the key factors influencing cannabis growth is lighting, and deep red supplemental lighting has emerged as a potentially advantageous method during the flowering stage. This article will explore the effects of incorporating deep red supplemental light on cannabis plants during their flowering stage, discussing its benefits, mechanisms, and potential drawbacks.
Understanding Cannabis Flowering and Lighting
The life cycle of cannabis plants consists of two primary stages: vegetative and flowering. During the vegetative stage, plants focus on developing their foliage, stems, and branches, while the flowering stage sees the plants shift towards producing buds, which contain the coveted cannabinoids and terpenes.
Lighting plays a critical role in regulating these growth stages, with the cannabis plant being particularly sensitive to the spectrum and intensity of light. While blue light is favoured during the vegetative stage, red and far-red light become more important during the flowering stage. This is where deep red supplemental lighting can offer significant benefits.
The Benefits of Deep Red Supplemental Lighting
Accelerated flowering and higher yields:
Deep red light (660 nm) stimulates the photosynthesis process and promotes cell division and elongation, which can lead to accelerated flowering and increased bud production. Supplementing traditional grow lights with deep red light during the flowering stage can therefore result in higher yields and more potent flowers.
Enhanced cannabinoid and terpene profiles:
Deep red light has been shown to promote the production of secondary metabolites in cannabis plants, including cannabinoids and terpenes. By incorporating deep red supplemental lighting during the flowering stage, growers can potentially enhance the quality, potency, and aroma of their cannabis flowers.
Deep red LEDs have a low energy consumption and generate minimal heat, making them an energy-efficient and cost-effective option for cannabis growers. By using deep red supplemental lighting, growers can reduce their overall energy usage while still enjoying the benefits of enhanced flowering.
Improved flowering under suboptimal conditions:
Cannabis plants can be sensitive to environmental conditions such as temperature and humidity. Deep red supplemental lighting can help to mitigate the impact of these suboptimal conditions, promoting healthy flowering even in less-than-ideal environments.
The Science Behind Deep Red Light
The cannabis plant’s response to deep red light is mediated by phytochrome proteins, which play a crucial role in the regulation of various physiological processes, including flowering. When these proteins absorb deep red light, they trigger a cascade of events that ultimately promote flowering and the production of secondary metabolites. This is why the addition of deep red light can enhance cannabis flowering and yield.
While deep red supplemental lighting offers numerous benefits, there are some potential drawbacks to consider:
Excessive deep red light can lead to overstimulation, causing the cannabis plants to become too tall and lanky with elongated internodes. This can compromise the overall structural integrity and stability of the plants, making them more prone to breaking or collapsing.
Diminished vegetative growth:
If deep red light is introduced too early or used excessively during the vegetative stage, it can suppress vegetative growth, leading to smaller plants with reduced foliage. This can ultimately impact the overall yield and potency of the cannabis flowers.
Incorporating deep red supplemental lighting during the flowering stage of cannabis cultivation can offer numerous benefits, including accelerated flowering, enhanced cannabinoid and terpene profiles, and improved energy efficiency. However, it is essential to strike the right balance when using deep red light to avoid overstimulation or diminished vegetative growth.
