5 Tips for how to optimize Cannabis yields by using LED grow lights

img 2253(20190727 094737)
As LED technology has advanced in recent years, more cannabis growers are moving to LED for their indoor operations. LEDs are now a great choice for indoor cultivators of all skill levels due to their many advantages, which include consuming less energy, being more durable, and having a longer life span. LED lighting will help you grow cannabis.

Many horticultural lighting companies aim to optimize cannabis production is hoping to squeeze in on cannabis production.

Advantages of LED technology:

As LED technology has advanced in recent years, more cannabis growers are moving to LED for their indoor operations. LEDs are an excellent choice for indoor cultivators due to less energy, more durability, and a longer life span. LED lighting will help you grow cannabis.

Better for Environment and Community:

LED grow lights provide more precise lighting while using 50-70% less energy than HPS; what’s more, LEDs minimize the emission and use of toxic gases while retaining high brightness.

  • Less Heat: LEDs run cooler than HPS, streamlining the ventilation process and costs and lowering environmental impact.
  • Fewer Chemicals: LED grow lights allow a highly controlled environment, significantly reducing the need for chemical treatments on plants.

The primary purpose of a controlled environment for prolong the growing season and increase crop production and quality.

  • LEDs are increasingly gaining popularity for use in agriculture in managed environments.
  • They’re more energy-efficient for a long time.
  • A new quick and modern harvest cycle has been introduced.
  • LED lights are becoming more popular as a result of their longer lifespan.
  • Since LED grow lights do not burn anything to generate light, they can save energy.
  •  LED lights are less harmful to plants than conventional lights.
  • LED grow lights are environmentally friendly products.

Light intensity:

We need to understand spectrum effects on photosynthesis. LED lights improved cannabis flower efficiency, consistency, and yield in a recent study ( Hawley, D., Graham, T., and Stasiak, M. Dixon). Yield and photosynthetic rate have a good relationship (Zelitch, I. (1975). For growers who are considering using led grow lights, we have five tips for you:

Raise the quality and predictability of your cannabis crop: The temperature in your greenhouse or sole source facility is more effectively monitored by using LED light. The LED light emits very little heat, allowing the atmosphere to be more easily controlled. This ensures good consistency and the correct composition of compounds throughout the year and the same quantity year after year to simplify logistical preparation and ensure efficient manufacturing. Using the specific light recipe can steer cannabis plant characteristics.

  1. Keep a close eye on your water intake:

Overwatering is a common mistake by growers when switching from HID to LED lighting. HID lighting produces heat and emits infrared light (IR), making the soil and plants dry out. Since LED grow lights don’t have the same amount of heat as conventional grow lights, they’re not as efficient.

  1. Mounting Height Matters:

Although we live in a plug-and-play culture, taking the time to install your LEDs properly will increase yield and efficiency. While many factors must be considered when mounting LEDs, such as the presence or absence of natural light, you want to ensure that your LEDs can maintain a broad, consistent light distribution concentrated deep into the environment. If you mount your LEDs too high, you can increase your coverage area and reduce the light’s intensity. If you place your LEDs too low, the proximity of the light will cause your plants to become stressed. Start with the LED manufacturer’s mounting guidelines, find out what your DLI (Daily Light Integral) is, and go from there.

  1. Install Multiple Units:

LED grow lights can create a targeted light output using optics, so you can also use an LED lamp to spotlight one section of your grow and repeat the process for each cluster in your growth. On the other hand, your plants will benefit from calculating and implementing multiple units in your grow facility. This allows the beams to overlap, resulting in optimal light distribution throughout the canopy. This could end up saving you a lot of money while still providing optimal lighting. Before you begin the installation, we recommend obtaining a light plane from a qualified lighting company; we can assist you with this.

  1. Define Your Light Cycles:

The biological life of your crop is set by light cycles. Indoor growers can change the hours of light and darkness to stimulate a plant’s photoperiod by increasing or decreasing the hours of light and darkness. During the long summer days, automated blackout curtains help growers block out unwanted sunlight and ensure needed dark periods, while supplemental lighting helps fill the light gap during the dark winter months. They are assuring that your plants receive all of the light they require. During the vegetative stage, the most common light cycle is 18 hours of light per day with 6 hours of darkness for flowers. The increased amount of uninterrupted darkness signals to the plant that falls is approaching, so a 12/12 light cycle will trigger flowering for most flower crops. 17-18 hours of light per day is highly recommended for the vegetative period.

Craft Light Recipes

Just as you can manipulate the photoperiod with LEDs, you can also use exposure to blue, white, red, and far-red spectrums at different stages in the growth cycle. While the flowering cycle can be influenced by multiple factors, crafting a custom light recipe that taps into the far-red spectrum has been shown to reduce the flowering cycle of plants, which expedites the time until harvest. A light formula also allows you as a grower to set the light intensity throughout the day.


Cannabis standardization is required to obtain consistent cannabinoid and terpene profiles and, subsequently, stable efficacy for medical purposes. Growing conditions and management practices should be optimized and standardized to maximize yields; light, temperature, CO2 concentration, irrigation, humidity, nutrients, and growing media combine and interact to affect the final yield.

Light energy is an essential factor for plant growth. Additional light sources are being used in regions where the natural light source (solar radiation) is insufficient for growth optimization. Traditional light sources such as high-pressure sodium lamps and other metal halide lamps are inefficient and generate high radiant heat. Therefore, Energy-efficient should develop new sustainable solutions for energy-efficient greenhouse lighting. Recent developments in light source technologies have opened up new perspectives for sustainable and highly efficient light sources in LEDs for greenhouse lighting. Traditional lamps should compare the effects of LEDs used in cannabis cultivation regarding cannabis yield and electricity consumption. The controlled environment should research optimal light conditions for cannabis under controlled environments to determine the optimized combination of light intensity with plant density for maximum plant yield.
