How to Choose the Best LED Grow Lights for Marijuana?

Plants' needs for grow lights vary among plants, and nowadays marijuana grow light techniques have been updated. To choose the best LED grow lights in 2024, consider these 3 key factors:

Light Spectrum

To choose the best LED grow lights, always look for grow lights that provide a full light spectrum (similar to natural sunlight). This includes adequate blue light for the weed vegetative stage and sufficient red light for the cannabis flowering stage. Different plants require different spectrums with red-to-blue light ratios.

Therefore, some smart LED grow lights like Medicgrow NEO-780 and NEO-1000 offer switchable light spectrums tailored for both the cannabis vegetative stage and the cannabis flowering stage, allowing you to customize the best red-to-blue light ratios for different cannabis grow stages.

Energy Efficiency

When it comes to the efficiency of LED grow lights for cannabis, we often think of wattage and PAR. However, experienced cannabis growers prioritize PPF and PPFD over PAR.

PPF indicates how many photons the light source emits, while PPFD measures how many of those photons actually reach the plant's surface. PAR represents the quality of the photon and cannot be measured with ordinary tools; in fact, measurements with a PAR meter result in PPFD levels rather than PAR.

Why does PPFD matter?

One of the necessary conditions for producing cannabis plants is adequate PAR, but now plant biologists typically use photosynthetic photon flux density (PPFD) to quantify PAR. This is because the chemical reactions of plants' photosynthesis depend more on the number of photons(PPFD) than the energy of photons(PAR).

Therefore, PPFD is generally considered the most important parameter, as it directly measures the number of photons the plants receive in the growing area, which directly impacts the efficiency of photosynthesis and the plant's growth.

Higher PPFD generally means your cannabis receives more energy and grows better while saving electric bills. It’s worth noting that Medicgrow Fold-800 produces up to 2080 µmol/s of PPF and when the light height is 12 inches, its PPFD can reach an impressive 1200 μmol/m2/s.

What's more? The Medicgrow NEO-780 LED grow lights are even better! We tested the Medicgrow NEO-780 PPFD this morning (July 31, 2024) using an Apogee MQ 500 PAR meter, and you can see that its PPFD can reach 1323 μmol/m2/s at 14 inches (36cm). Even at 24 inches (61cm), it can still achieve a remarkable result of 1054 μmol/m2/s.

 Medicgrow NEO-780 PPFD

As you can see, the PPFD value of the Medicgrow NEO-780 is significantly higher than that of other LED grow lights. This high PPFD value facilitates faster and bountiful marijuana growth.

It's also important to note that if the LED grow light PPFD value exceeds 1000, it is necessary to add sufficient CO2 to enhance cannabis growth. We don't recommend purchasing an LED grow light with a PPFD value below 600, as it may lead to poor cannabis growth.

Coverage Area

The area covered by LED grow lights is one of the most important factors for growing cannabis. Proper coverage area ensures that light is evenly distributed across all cannabis, leading to higher yields. Uneven light distribution can lead to some cannabis receiving too much light (causing light burn) while others receive too little (leading to weak growth).

Therefore, measuring the area of your indoor grow room and choosing the right size for weed growing lights, as well as determining the appropriate hanging heights, will ensure that the cannabis plants receive the light they need to thrive.

Now that we know how to choose the best LED grow lights. By combining your expert cannabis growing skills with our hand-picked 5 best LED grow lights for cannabis, we're confident that you can increase your yields by 15% to 20% this year!

This is the latest picture from a customer using the Medicgrow Fold-8, you can see that with the help of the Medicgrow LED grow light, the buds are very dense and full, and the yield is excellent.

5 Top Rated LED Grow Lights 2024

In recent years, with the advancement of LED technology, many LED grow lights for cannabis have undergone significant updates. Philips Lighting experimented in greenhouses and found that the best light recipe was not the same for all plants.

3. Spider Farmer (Most Energy Savings)

Spider Farmer is dedicated to improving cannabis cultivation. Their LED grow lights for cannabis provide the ideal spectrum to ensure weed thrives and grows healthily.

The Spider Farmer SE1000W also uses passive materials to prevent the light itself from overheating, which means your cannabis plants won't overheat and you'll save energy.

These weed-growing lights are the most energy-efficient option compared to other LED grow lights for cannabis, but they are pricey, especially when compared to the Medicgrow Fold-800, which sells for only $280! Let's take a look at the Spider Farmer SE1000 specifications to learn more about it.

1. LED vs HID, Which is the Best Grow Light for Cannabis?

LED grow lights are the best grow lights for cannabis because they are energy-efficient, have a long lifespan, and offer a full spectrum of light tailored to different cannabis growth stages. They also generate less heat, reducing the need for extensive cooling systems.

On the other hand, HID grow lights are known for their high intensity. They provide deep light penetration, but they consume more electricity, generate significant heat, and require frequent bulb replacements. For these reasons, HIDs are now overtaken by LED grow lights.

2. What Are the Best LED Grow Lights for Beginners?

The best LED grow lights for beginners are those easy to use and energy-efficient. Options like the Medicgrow Fold-800 and Medicgrow NEO-780 provide a full spectrum of light suitable for all cannabis growth stages and are beginner-friendly with simple setups, minimal heat output, and higher PPFD.

3. Will Any Grow Lights Work for Cannabis?

Not all grow lights are suitable for cannabis cultivation. The best grow lights for marijuana include LED and HID lights, as they provide the necessary light intensity and spectrum for different growth stages.

Besides, LED grow lights for cannabis are particularly favored for their energy efficiency, low heat output, and customizable spectrum, making them ideal weed-growing lights for all stages of cannabis growth.
