How Do LED Grow Lights Promote Growth and Blooming?
Before we dive into how to choose the best LED grow light, let’s look at why LED grow lights are so popular: How do LED grow lights promote growth and blooming?
In the spectrum of LED grow lights, blue and red light are the most important. Blue light (450-495 nm) promotes the absorption of chlorophyll by plants and enhances photosynthesis efficiency, thus boosting plant growth.
In contrast, red light (620-750 nm) in LED grow lights aids in nutrient accumulation, strengthens plants, and promotes flowering and fruiting.
Full-spectrum LED grow lights like the Medicgrow LED grow lights, not only provide a good balance of red and blue light but also include violet light (380-450 nm) and green light (495-570 nm), which increase plants' disease resistance and promote metabolism.
In summary, LED grow lights not only simulate sunlight by providing a diverse spectrum of light but also emit the high photon flux (PPF) needed for plant growth, enhancing photosynthesis efficiency and promoting growth.
How to Choose the Best LED Grow Light?
LED grow lights are popular for their high energy efficiency, long lifespan, and suitable spectrum. You should do your homework before selecting LED grow lights to understand the growth needs of the plants you are cultivating, including the best spectrum, optimal light intensity, photoperiod, and the hanging height of the grow light.
Make sure the LED grow lights you choose provide sufficient but not excessive light intensity (PPF) and the correct spectrum to meet your plants' needs at different growth stages.
Take marijuana for example:
- In the seedling stage, a recommended PPFD value of 100-300 μmol/m²/s is suggested to avoid excessive light intensity that could harm the seedlings.
- During the vegetative stage, a PPFD value of 400-600 μmol/m²/s is recommended, with an increased amount of blue light to promote healthy leaf, branch, and stem growth.
- In the flowering stage, a light intensity of 600-900 μmol/m²/s with more red light is recommended to enhance production and increase yields.
Additionally, choose lights with the appropriate coverage area for the size of your growing space and pay attention to the thermal performance of the light to save on energy costs and maximize yields.
For a small grow tent (60x60 cm), I recommend 100-200 watts.
For a medium-sized grow tent (90x90 cm), a power range of 250-400 watts is recommended to ensure even light coverage.
A large grow tent (120x120 cm) requires a stronger light source, so 400-600 watts is suitable.
For grow tents that are 150x150 cm or larger, 600-1000 watts or more are necessary to ensure each plant receives sufficient light.
Also consider the energy efficiency and cost-benefit ratio of the LED grow lights by comparing parameters such as PPF, wattage, and price.
Lastly, choose well-known brands and products with good customer reviews, long warranties, and responsive customer service to ensure a more enjoyable growing experience.
To sum up, when choosing the right grow light, it’s important to prioritize light intensity, spectrum, wattage, and whether the light is appropriate for your grow tent size.
Best LED Grow Lights Recommendations for 2024
When selecting the best LED grow lights, I highly recommend Medicgrow grow lights. Medicgrow is known for its high energy efficiency, long lifespan, and suitable spectrum.
Their lights provide high light intensity (PPF) and light output (PPE), adjustable light cycles and intensities, and a sufficiently large coverage area to ensure optimal plant performance at various growth stages.
Moreover, Medicgrow LED grow lights are cost-effective, available directly from the manufacturer, have long warranty periods, and are highly rated by customers, making them the ideal choice for growers.
Products from Medicgrow, such as the MINI SUN-2, NEO-780, and FLEX-800 series, offer full-spectrum lighting through advanced technology and design, passive cooling, and intelligent control systems. The MINI SUN-2 is ideal for home and small-scale cultivation, offering high efficiency and energy savings.
The NEO-780 grow light features integrated functions like timers, dimming, spectrum adjustment, sunrise, and sunset settings, making it suitable for professional growers.
The FLEX-800 series provides strong performance and coverage, is foldable, and easy to install. These features make Medicgrow the recommended brand for the best LED grow lights in 2024.
With the help of the MedicGrow FLEX series, commercial growers have achieved great success. Here are some case studies.
How to Test and Compare LED Grow Lights?
Testing LED grow lights can help you determine their performance and effectiveness. Here are some common testing methods:
Spectrum
Use a spectrometer to measure the spectral distribution of the grow light. Ensure the emitted light contains the necessary blue and red light for plant growth. We usually recommend a full-spectrum LED grow light like the Medicgrow NEO-780.
Light Intensity
Use a quantum meter (PAR meter) to measure the photosynthetically active radiation (PAR) at different distances. The unit is micromoles per square meter per second (µmol/m²/s). This helps you determine if the light intensity in the plant growth area is sufficient.
This is a PPFD measurement of the NEO-780 taken at a distance of 36 centimeters using a PAR meter. As you can see, even at this distance, it reaches an impressive PPFD value of 1323 µmol/m²/s. This clearly demonstrates the high efficiency and uniform light distribution of the NEO-780.
Uniformity
Measure light intensity at different spots in the growing area to ensure the light is evenly distributed. Even lighting can prevent plants from growing unevenly due to insufficient or excessive light. A suitable LED grow light coverage area and hanging height can ensure uniform light distribution.
Energy Consumption
Use a power meter to measure the energy consumption of the LED grow light. Ensure the grow light operates efficiently without consuming too much energy. Or you can simply observe the changes in your electricity bill.
