LED Grow Lights for Cannabis: The Importance of Temperature Control

LED grow lights offer many advantages to growers compared to traditional lamps and are therefore highly preferred. An important factor to consider when using LED lights is temperature control. In this article, we will clarify this issue.

Important For Cannabis Growth Under LED Grow Lights

Temperature control is very important because cannabis plants are sensitive to temperature extremes. If the temperature is too low, the plant may not grow as fast as before, and if it is too high, the plant may not be able to give the desired yield by getting stressed.

LED grow lights emit less heat than traditional HID lights, but they still generate heat. It is very important to ensure that the grow room or tent is properly ventilated and the temperature is kept in the optimal range for cannabis growth, i.e. between 20°C to 30°C (68°F to 86°F) during the day and 18°C to 26°C at night ( 64°F to 79°F).

In addition to temperature control, it is important to consider humidity levels in the grow room. High humidity causes mold growth, while low humidity can cause plants to become dehydrated. Aim for a humidity level of 40% to 60% during the vegetative phase and approximately 50% to 60% during the flowering phase.

The power of the LED grow light will determine how much energy is consumed by the light and how much heat it produces. Higher wattage lights will generate more heat, so it's important to choose the appropriate wattage for your growing area.

The spectrum of the LED grow light is also important as it will affect the growth and development of plants. The cannabis plant needs a full spectrum of light, including blue light for vegetative growth and red light for flowering. Some LED grow lights are designed to provide a full spectrum of light, while others may be more specific for certain growth stages.

Intensity is another factor to consider when choosing an LED grow light. The intensity of light affects how much energy the plant receives and how fast it grows. Some LED grow lights can be too intense for young plants, so it's important to adjust the intensity as needed throughout the growth cycle.

The Best LED Grow Lights for Growing Cannabis in a Cabinet


When it comes to growing cannabis in the closet, LED grow lights are a great choice because they're energy efficient and don't generate as much heat as other grow lights. We have selected for you the best LED lamp with a full spectrum of light for optimal growth and perfect for a small closet:


Kind Led Grow Light Bar X40 


The Kind LED Grow Light Bar X40 is a high-quality LED grow light that is designed for use in smaller grow spaces like closets or grow tents. It features a slim, low-profile design that makes it easy to install and mount in tight spaces. The X40 produces a full spectrum of light, including infrared and ultraviolet light, to support all stages of plant growth.


One of the standout features of the X40 is its use of secondary optical lenses, which focus and intensify the light for more efficient and effective plant growth. This helps to ensure that your plants are getting the maximum amount of usable light, which can lead to healthier growth and better yields.


The X40 is also energy-efficient, using just 40 watts of power while still delivering a high level of light output. This makes it an environmentally-friendly and cost-effective choice for growers who want to minimize their energy usage and expenses.

LED Grow Lights for Cannabis: The Importance of Light Intensity


The light intensity to which your plants are exposed is one of the most important factors to consider when growing cannabis. LED grow lights are an efficient and effective means of providing the appropriate light intensity that cannabis plants need for optimum growth. In this article, we will talk about how you should adjust the light intensity.


From Seed to Harvest: The Importance of Proper Light Intensity for Cannabis Growth with LED Grow Lights


Light intensity is measured in units called lux or foot wax, but in the case of growing cannabis the most appropriate unit is micromoles/square meter/second (µmol/m²/s). This unit measures the number of photons (light particles) falling on one square meter of vegetation per second.


Different stages of cannabis growth require different light intensities. In the vegetative stage, plants require a lower light intensity of about 200-400 µmol/m²/s. This is because plants have leaves and stems still growing, and too much light intensity can actually damage young plants.


During the flowering phase, plants require a higher light intensity of about 600-1000 µmol/m²/s. This is because plants focus on producing flowers and need more energy to do so.


How to Optimize Light Intensity for Cannabis Growth with LED Grow Lights


It's also important to note that light intensity can vary depending on the distance between LED grow lights and plants. The closer the lights are to the plants, the higher the light intensity and vice versa.


In addition to adjusting the light intensity according to the growth stage, it is also important to consider the particular strain of cannabis being grown. Some strains are more sensitive to light intensity and may require lower or higher levels than others.


In addition, the size of the growing area and the number of plants grown can also affect the light intensity required. A larger growing area may require more powerful LED grow lights or additional lighting fixtures to provide proper coverage and density on all plants.


It is also important to consider the light exposure time or photoperiod for the cannabis plant. In the vegetative stage, most growers use an 18 hour on and 6 hour off light cycle. During the flowering phase, the light cycle is often changed to 12 hours on and 12 hours off to stimulate bud production.

LED Grow Lights for Cannabis: The Importance of Red and Blue Light


LED grow lights have become increasingly popular with cannabis growers, thanks to the many benefits they offer. You can use various colors of light with LED lamps, but when it comes to growing cannabis, basically red and blue light is of great importance. Let's take a brief look at the reasons for this.


The Role of Red and Blue Light in Cannabis Cultivation: Why LED Grow Lights are Essential


The Impact of Red Light


Red light is required for the cannabis plant during the flowering period. The plant's chlorophyll absorbs it and helps trigger the flowering response. Red light has a longer wavelength, which means it can penetrate deeper into the canopy of the plant and reach the lower leaves and flowers. This is especially important for cannabis plants, as they can grow quite tall and bushy and without adequate light penetration the lower parts of the plant may not receive enough light to produce high quality buds.


The Power of Blue Light on Plant Growth and Development


On the other hand, blue light is important in the vegetative stage of cannabis growth. The plant's chlorophyll absorbs it and helps support leaf growth and overall plant development. Blue light has a shorter wavelength, which means it is less able to penetrate the plant's canopy but is still essential to provide the plant with the energy it needs to grow and develop properly.


Providing both a red and blue spectrum of light, LED grow lights are ideal for cannabis cultivation as they can provide the right wavelengths of light at the right stages of growth. However, it's important to note that cannabis plants also benefit from other wavelengths of light, including green and yellow light, so it's important to choose a grow light that provides a full spectrum of light to ensure optimum growth and yield.
