Whether you live in an extremely hot country or colder climate, there are a lot of factors to consider when growing your marijuana. To do so, grow lights are highly advisable if you want to do it successfully at home.

Numerous lighting systems are available for you, but which one you select highly depends on your knowledge and setup. Therefore, before considering growing your marijuana, you need to know the capabilities of particular indoor lighting setups to identify which are the best grow lights for Marijuana for you.

What are the Best Grow Lights for Marijuana on the Market?

Let’s take a look at some top grow lights for Marijuana on the market:

Roleadro LED Panel
Apollo Horticulture MH Light
Lithonia Lighting GRW
G8LED Mega Grow Light
Lightworks Solarstorm LED Grow Light

1. Roleadro LED Panel

Roleadro LED Panel lights are used on their own or alongside other lamps. This light is highly versatile and loved by growers. Knowing that it can reach plants up to 8 feet away from it allows you to compute how many lights you require for your particular growing space.

It also emits blue and red light, which can be used during the vegetative and growth stage, saving you the hassle of switching your lighting system and possibly disturbing your plant’s growth. With a service life of over 50,000 hours and barely emitting heat while switched on, this light is reliable and does not harm your plants over long periods.

2. Apollo Horticulture MH Light

The Apollo Horticulture lamp is perfect while your plants are within the vegetative stage and offer further options to optimize growth during the flowering stages. For example, if you purchase a dimmable ballast with the light, you can up the brightness or dim the light as needed, tailoring your plant’s growth more specifically.

3. Lithonia Lighting GRW

The Lithonia Lighting GRW is simple to set up and easy to use straight after purchasing. This lighting system requires a plug-in wall socket. With adjustable chains, you can hang and use them in growing outdoor houses or larger indoor growing rooms. It also has an adaptable lens that concentrates light towards particular plants to aid growth and yield.

4. G8LED Mega Grow Light

Still popular after eight years on the market, the G8LED Mega Grow Light is best for growing marijuana indoors and provides everything they will need. The light is renowned for producing high yields with a light coverage of over 18 square feet. There is also the option to add a 90W red light booster that enhances the production of cannabinoids. How is it so reliant? The light has clever inbuilt cooling fans that prevent it from overheating and the excess light burning your plants.

5. Lightworks Solarstorm LED Grow Light

This recommended light provides every light spectrum required for your marijuana plants in the deepest colors and varieties. The Lightworks Solarstorm growing light has five bands of high PAR (Photosynthetic Active Radiation) and is dual operating, unlike other full-spectrum lights, producing high yields in small and large growing settings.

Understanding the Terminology Before Choosing the Best Grow Lights for Marijuana

Learning keywords and exploring how their differences affect your growing capabilities is crucial to select which lighting setup is best for you. Picking the best lights to grow your plants is not just about paying the highest price tag; it’s about the light’s specific settings and highly depends on how many plants you have and where you are growing them.

Light Spectrum

Similar to other species of plant, marijuana requires different light spectrums to grow; hence its denoted as being ‘photoperiod.’ During the vegetative stage, marijuana requires up to 18-24 hours of blue-spectrum light.

This light spectrum has a wavelength of 400-500 nm and catalyzes peak chlorophyll pigmentation and absorption, leading to the establishment of the marijuana’s healthy root and stem structure. Afterward, stem and leaf growth requires a red light of 600-700 nm.

Wattage

The wattage of a lighting system is essential to pay attention to as it gives a good indication of how many lights you may need. For example, if you have a smaller-sized growing space, then one light with a high wattage will give the plants sufficient lighting. Or you may prefer to surround your plants with more reduced wattage lights.

Lumens

Lumens are crucial for the successful growth of photoperiod plants. Lumens is a quantification of how much light emits each second when switched on. Like the different light spectrums that these plants require, they also need varying amounts of lumens during each phase. For example, about 2-5000 lumens are necessary during the blue stage, exceeding 10,000 within the flowering phase.

Kelvins

As well as understanding how much light to emit, kelvins are essential to comprehend as they indicate the warmth and color of the light radiated. As previously mentioned, marijuana requires a blue light, otherwise known as an excellent light, of around 2,700 kelvins during the vegetative growth stage. Yet, throughout the red-light stage, a warmer light with 2,500 kelvins is needed to support the main body of the plant’s growth.

Getting To Know the Four Main Types of Grow Lights

Growers should also get to know the four different types of lamps. Fluorescent, high-intensity discharge (HID), LED, and induction grow lights are all available on the market, each with different lighting settings.

1. Fluorescent Grow Lights

These lights use little electricity from long tubes and twisted bulbs and are essential indoor lights for herb gardens. CFL grow lights can be purchased anywhere and come as a twisty bulb, easily fitted into any space. T5 grow lights are the most readily available for growing indoor plants, including marijuana. Due to this, they can be bought in most garden centers and come as a long panel that can be fitted hanging inches above your plants without harming them.

Pros: as well as being cheap to supply, they don’t use a lot of electricity and grant your marijuana plants the right light spectrums.

Cons: Fluorescent grow lights produce smaller yields per watt output. For example, every watt has only 0.25 grams of buds fed and produced.

2. High-Intensity Discharge (HID) Grow Lights

Usually screwed into a reflector or hood, high-intensity discharge lights are more efficient at distributing light onto plants than fluorescent versions. Metal Halide Intensity lights are implemented during the vegetative stage as they produce a pure blue light in which the young plants thrive.

Due to its adequate yellow and red light, you should use a High-Pressure Sodium growth light during the flowering stage. These lights produce a better yield per watt of electricity than others on the market, making them very popular and recommended.

Pros: They are the most efficient and suggested to be the best light to use during the flowering stage of growth. They can be hung at any distance from your plants and are easily adaptable.

Cons: Due to their excellent heat production, they tend to overheat, so you must also have a cooling system in place and ventilation. A cooling system is critical with larger lights that have over 250W power as they can enhance the ambient temperature of your growing room.

3. LED Grow Lights

With their cooler aesthetic and built-in cooling system, LED (Light-emitting diode) grow lights are trendy amongst marijuana growers. Plugged into a wall socket and hung over your plants, LEDs make the growing and harvesting of marijuana seem rather doable.

Pros: Unlike the High-Intensity Discharge grow lights, LEDs don’t need ventilation or an added cooling system as their system design pushes heat up from the plants, effectively cooling them. The light spectrums they produce also have significant penetration, so they can be set up in one location and not move around.

Cons: They are easy to use, but there is still a lot to learn. Growers must take time to test out different LED lights and compare which one produces the best yield. LEDs are known to have slightly lower results per watt compared to HPS grow lights. They also require more space between the light and the plants, which could restrict where and how many plants you can grow, as a taller ceiling would be required.

4. Induction Grow Lights

Despite being rarely used, induction grow lights have a super long lifespan of 100,000 hours with lower depreciation than LED grow lights. Induction grow lights are also far more economical than LED grow lights, especially for high-power situations like 300w or 400w light sources. Lastly, Induction Grow Light provides more customized light and spectrum the plants need, while the lighting options offered by LED can be minimal.
