When growing your cannabis plants indoors, you need to produce the magic of the sun with LED grow lights to help your plants thrive well. Compared to other grow lights LEDs are special as they give your cannabis plants almost optimal environment for their growth throughout the life cycle. Below is a list of what LED can give to your cannabis plants:
- Full Color/light spectrum
In order to grow healthier cannabis and get better yields, you need adequate light intensity and quality light that your plants would get if they were grown outdoors under natural sunlight. Sunlight has many spectrum that we cannot see with our naked eyes such as infrared and ultraviolet.
LEDs that are designed to grow plants can work well for cannabis. best led grow lights produce different light spectrums that are used by cannabis plants through different stages of growth. Such light spectrums include:
- Ultraviolet light (UV)
Ultraviolet light has a spectral band of 10 to 400nm. UV light is said to be the major contributor for plant tastes, aroma and colors. This means it affects metabolic process. Studies have shown that UV light helps in accumulation of phenolic compounds that enhance plants extract antioxidant activity. UVB has been demonstrated to increase levels of Tetrahyrocannabinol (THC) which is a very important cannabis extract.
- Blue light
Has a spectral band of 430 to 450nm which enables phototropins and cryptochromes of cannabis plant to initiate stomata opening, elongation growth, chloroplast movement and seedling growth. In simple terms, blue light is important as it encourage vegetative growth of cannabis plants.
- Green light
Green light produced by LEDs has a spectral band of 500 to 550nm and has smaller role in cannabis growth. This light’s benefits are not well understood by studies show it encourages stomata opening and environmental signaling in cannabis plants. When combined with red, far-red and blue, green light completes a spectral treatment for understanding your plants physiological activity.
- Far-red light
Has a wavelength of 730nm and is very important in cannabis plants bearing in mind they are short-day plants. The wavelength of far-red light is outside the active range of photosynthesis and is not important during vegetative stages of your cannabis plants. However, it can be of important use in flowering cannabis.
- Red light
Has a light wavelength of 640 to 680nm. This light is very important in flowering and seed formation of your cannabis plants. The strong light wavelength is very important in flowering, stem growth and chlorophyll production in cannabis plants.
Why spectrum range is important for cannabis?
A mixture of light spectrum as produced by LED grow lights is used to promote different stages of cannabis growth. This helps explain why LED grow lights are better in growth of cannabis compared to other grow lights. Variety of spectrum can help design your cannabis based on what you want from them. Different aspects of the end products in cannabis will help explain why LEDs are suitable in your cannabis growth.
These aspects include:
- Flower cosmetic appeal
- Concentration of the fragrance
- Flower density- This entails oil and wax ratio and resin content
- Flower weight
- Potency- Entails CBD and THC levels
Though there is no ideal spectrum to help achieve all these aspects you can use different LEDs with different lights at different growth stages of your cannabis to achieve what you want.
- Cool Temperature
LED grow lights do not produce much heat hence they give your plants a cool environment especially when there is optimal temperature for your plants. They help you save extra costs you would incur installing cooling systems.
- Enough time to grow
Many LEDs sold in the market today have been proven to have a life of up to 100,000 hours. Such LEDs give your plants enough time to go through all phases of growth till harvest time. This reduces the need to purchase new LEDs within a short period.
