Can ordinary LED lights grow marijuana indoors?

Cannabis is a sun-loving short-day plant, which has extremely high requirements for light. If the light intensity does not meet the requirements, it will affect its growth. “Generally, it is not recommended that users use ordinary LED lighting to grow cannabis, especially Planting in the greenhouse or in the basement, affected by the building materials, the light is weakened or even completely dark, which has a great impact on the growth of cannabis and the differentiation of flower buds, so the cannabis should be replenished in time.

Since industrial hemp has high requirements for light intensity, when choosing a fill light, pay attention to the power of the fill light. It is best to choose a high-power LED plant light, which can not only ensure light intensity but also save energy. High-power LED grow lights can be combined according to needs to meet the requirements of plants for light intensity, and are very suitable for greenhouse projects, greenhouse planting, and plant planting.

With the increasing legalization of marijuana, research on marijuana cultivation has become more and more extensive, including the types of marijuana, growth stages, cultivation methods, and suitable growing environment. LED grow light is a kind of light source that uses LED (light emitting diode) as an illuminant and artificial light source to meet the lighting conditions of plant photosynthesis. In a sunny environment, the lamp acts as sunlight, allowing plants to grow or develop normally. Lights help cannabis promote strong root and fruit ripening, including regulating flowering and enhancing quality!


Features of LED grow lights:

  • Rich wavelength types;
  • It fully conforms to the spectral range of plant photosynthesis and photomorphology;
  • Spectral waves can be combined to obtain pure monochromatic light and composite spectra;
  • The light balance can be concentrated on a specific wavelength to illuminate the crops;
  • It not only regulates the flowering and firmness of crops but also controls the nutrients of plants;
  • The system generates less heat and occupies less space;


In the greenhouse, you can choose LED plant lights to fill the light for cannabis, but when choosing fill lights, you should pay attention to the power of the plant lights. The high-power plant lights are powerful and can meet the lighting requirements of cannabis growth. If the temperature in the greenhouse is high, the water vapor is large, and the greenhouse needs to be watered with water, then the selected plant light should also pay attention to the waterproof function. The high power of the plant light will lead to an increase in heat generation, so it is better to have a heat dissipation facility for the plant light, which can prolong the service life of the plant light.

Grow lights provide a spectrum similar to the sun, a custom spectrum that better meets the needs of cultivated plants. Spectral output forms grow lights with different colors, simulating outdoor conditions and providing extended control to maintain light output to plants. Different growth stages of plants require specific spectral ranges, depending on the type of plant, growth stage, and photoperiod required by the plant.

Especially for growers looking to achieve promising crop performance, maximize profits, and make their crops show different characteristics, grow lights offer solutions that help achieve these goals. Both new and professional indoor growers generally require greater plant spectral flexibility to elicit the desired response at different growth stages of the plant. From growing to harvest, indoor medical cannabis plants require a specific spectrum suited to their growing needs.

Indoor medical marijuana cultivation requires an understanding of certain factors, such as plant density, grow light heights, spectral changes, and light intensity. There is a need to clarify what features are required of indoor medical marijuana grow lighting systems that allow medical marijuana growers to better control the factors that affect plant growth.
