What kind of grow LED lamp do you need to grow microgreens, vegetables or flowers? You can learn from this article!


LED grow lamps are the most efficient lighting solutions for indoor and greenhouse growers or aquarium owners. For detailed information on the history and operation of LED lights can be found on Wikipedia or the manufacturers’ pages. In this article you will understand the characteristics, possibilities of use and technical comparison of top quality and professional grow LED lamps.

Grow LED Properties:

Typical characteristics of conventional bulbs (CFL, T5, CMH, HPS) are given in Watt, Lumen, Kelvin, which are suitable for human light detection, but not precise enough to measure the light demand of plants. Modern grow LED lamps have been specifically developed to meet the needs of plants to provide the right amount and quality of light throughout the entire life cycle. For traditional lamps, you may need to use 2-3 types of bulbs in different life cycles to get the best results, while LED lamps meets all the requirements all in one.

When selecting and using a horticulture LED lamp you need to know PAR, PPF, PPFD, PE, IP values to achieve the expected results.

PAR: Photosynthetic Active Radiation, The wavelength of the active radiation required to control photosynthesis is indicated by the term PAR, which is determined by the nanometer value. The plants require a light spectrum between 400-740 nanometers for photosynthesis at different stages of their development. In the seedlings and vegetative cycle, more blue light (400-550nm) is needed for the plants while in the flowering and fruit production cycle more red light (650-740nm) needed, so it’s the best to provide a mixed light spectrum (to mimic the sun spectrum) with a full spectrum grow LED lamp.

PPF: Photosynthetic Photon Flux, PPF is the amount of photons generated per second by the LED light source, measured in micromoles per second (µmol / s). PPF can be measured using a special quantum sensor (PAR meter).

PPFD: Photosynthetic Photon Flux Density, The PPFD value indicates the intensity of the LED illumination, that is, the amount of photons generated per second by the light source per square meter, measured in micromoles / m2 / second (µmol / m2 / s).

PE: Photon Efficiency, Photon Efficiency of a grow LED lamp means that the system transforms electrical energy into effective photosynthetic active radiation (PAR), which value is given by the manufacturers in micromol / jules (umol / J).

IP: Ingress Protection, The level of protection against water or dust penetration is indicated by IP4X, IP5X, IP6X. Grow LEDs suitable for plant cultivation are generally more than IP5X-protected, which works well even at humidity levels above 90%. Grow LED lamps for greenhouses and aquariums are IP6X protected, fully waterproof at 100% humidity.

Compact grow LED lamps (10W-140W)

compact grow led

If you want to sprout and grow microgreens in a small place, you need a compact and power efficient plant LED lamp.

Manufacturers mainly offer LED strip models with low power consumption which covers the low light demand plants (microgreens) and provide the right amount and spectrum of light needed. The size of the lamps varies from 40cm to 120cm, the performance depends on the size (10-50W). Because microgreens and sprouts need 100-300 ppfd, well-designed lighting is very important. Modern LED strips are designed to meet the needs of plants in the germination and seedling phase with a full light spectrum of 400-700nm. Grow LED strips are fully waterproof IP65-IP68 and can even be controlled in groups, allowing you to reach the necessery amount of PPFD that plants need at a given stage of their life cycle. These models generally have the ability to adjust the light intensity for precise setting of PPFD and provide the flexibility to adjust the lighting conditions. These compact Grow lamps have everything you need to start growing right away.

CO2 supplement

Due to the large amount of light, the plant is able to develop better and therefore needs more carbon dioxide.

The table below gives a recommendation on the CO2 supplement for intensive plant production.

-100 and 300 μmol / m2 / s for seeds and germination (under optimal conditions: additional CO2, ~ 400 ppm)

-75 and 150 μmol / m2 / s for seedlings, clones (under optimal conditions: additional CO2, ~ 400-800 ppm)

-300 and 600 μmol / m2 / s in the development phase (optimal results: additional CO2, ~ 400-800 ppm)

-600 and 1000 μmol / m2 / s for optimal results during flowering / reproduction phase without additional CO2 (wonderful results: additional CO2, ~ 800-1400 ppm)

-1000 and 1500 μmol / m2 / s for outstanding results during flowering / reproduction phase with additional CO2, ~ 1400 ppm.


Due to the low electricity consumption and the long life of LEDs, grow LEDs are the new direction of indoor and greenhouse grow lighting.
