Best LED Grow Lights
The quality of light in your grow room is the most important environmental factor in the quantity and quality of your cannabis yields, so be smart about how you choose the best lighting setup. In fact, if you plan on growing your own weed as a long-term investment, we highly recommend you spend a decent amount of money buying the best grow lights you can afford!
Here’s a brief rundown of why top-rated full spectrum LED grow lights are the most popular among for growing cannabis indoors!
Benefits of LED Grow Lights For Cannabis
The benefits of LED grow lights are as follows:
- LEDs last much longer than other light bulbs and setups
- consume far less electricity, making your grow more profitable and efficient
- offer large coverage of your grow area
- create less heat, meaning your cost of ventilation and air conditioning is lower
- and the best LED grow lights are designed to generate a fuller spectrum of light, resulting in higher yields and better quality marijuana
If cheap LED grow lights aren’t in your budget, then you may consider a fluorescent system. Fluorescent grow lights and setups, especially using high-output (HO) T5 bulbs, are also popular among small hobby growers because they tend to be very affordable.
The cost of T5 grow lights and bulbs are low because most packages come with a reflector, ballast and bulbs. Furthermore, T5 bulbs don’t require a cooling system because very little heat is generated.
Whether you pick a T5 vs. LED grow light really depends on what you’re trying to achieve. Serious marijuana growers will often pick LED lights for their long-term benefits.
How To Choose The Best Grow Light
Choosing the best light for your grow room depends on a few factors. From the area you need covered to whether you want an all-purpose light for both growing and flowering, we will help you pick the best LED grow light for the money!
For starters, the right grow light for indoor plants must cover the area where you grow. Determining the amount of space you need is easy if you plan to use a grow tent for your cannabis; otherwise, measure the area your lighting system needs to shine on.
In order to cover more space, you may need to buy more lights and install them adjacent to each other. However, LEDs can save you money in this respect since high-intensity LED setups often offer more lighting coverage than their alternatives.
Nevertheless, if you’re a grower who wants to be able to position light units in specific spots, you may want to buy two small grow lights versus one large panel. This may turn out to be another benefit, as experiments have shown that growers get better results with many smaller LED panels (e.g. 2 x 300W units) as opposed to a few big panels (1 x 600W unit). This is because more units make it easier to spread the light to all areas of your indoor grow. Fortunately, the high-wattage panels we’ve reviewed don’t have an issue with light intensity.
As for wattage, your ultimate goal with LED lights should be to provide 50 watts per square foot of grow space.
Phases of Plant Growth
Different grow lights provide different wavelengths, unless you want an all-purpose light. If not, you’ll need to buy different lamps for growing (vegging) and flowering (budding). To save money, we recommend one light for the full-growth cycle. For this approach, make sure you buy a full-spectrum LED grow light that works in all phases of plant growth!
The majority of the grow lights we’ve rated and reviewed provide all necessary wavelengths, including infrared and ultraviolet – the parts of the spectrum you can’t see with the naked eye.
Cost and Budget
Like anything else, you get what you pay for. The best indoor grow lights for weed aren’t cheap. But for what you pay upfront for your lights, cannabis growers tend to make back their money with higher yields, increased potency, and lower electric bills.
Nevertheless, we appreciate the fact that some beginners are on a tight budget. For this reason, we’ve included a number of affordable and even cheap options to accommodate everyone!
LED Grow Light Reviews
Here is our list of top LED grow lights for sale based on features, price, and the results they’ve shown in maximizing yield and quality for growers. The top LED light brands for growing marijuana include PlatinumLED, G8LED, Galaxy Hydro, Kind LEDs, ViparSpectra, and Apollo.
Advanced Platinum Series P900
The Advanced Platinum Series P900 is a product of PlatinumLED Grow Lights, a reputable company that incorporates revolutionary full-spectrum technology into their entire product line. The brand excels at providing your plants with all their light needs to ensure maximum yield and minimum power usage, all the while keeping your grow room cool.
Here are some basic specs of the P900:
- Equivalent to a 1000-watt HPS grow light, but only consumes 515 watts of power
- Complete 12-band spectrum, including UV and IR
- Max Coverage at 18″: 6’x4′
- Core Coverage at 18″: 5’x3′
- LED Quantity: 300 x 3W
- Lifespan: 50,000 to 100,000 hours
- Warranty: 5 Years
The P900 also comes with the company’s trademarked “3x intensity” lights that give three times the brightness of other LED grow lights. However, this panel is great for both the vegging and budding stages of cannabis growth. By simply hitting the “Veg” or “Bloom” switch, you can control the intensity of the light. Combined with the integrated 90-degree focusing lenses that allows for deep penetration into the canopy of your plants, the P900 is as close to sunlight as you can get for your indoor cannabis grow.
What ultimately makes the P900 the best LED grow light for marijuana is the large coverage area one panel can provide. When suspended 18 inches above your plants, its maximum coverage is 6 x 4 feet, and core coverage is 5 by 3 feet. The difference in these areas is due to the fact that different stages of growth require different light intensity.
Hence, for the sprouting stage, you can cover more surface area. But at the flowering stage, where you need intense light strength, you’ll be able to cover less area. The bottom line is that, since an adult cannabis takes up a little over 1 square foot of space in a 3-gallon pot, the P900 can conservatively flower between 12 and 20 plants at a time.
Lastly, with a 90-day money-back guarantee and a 5-year complete warrant, you can’t go wrong using the Advanced Platinum Series P900.
Advanced Platinum Series P600
The Advanced Platinum Series P600 is another advanced grow light from PlatinumLED. Built on much of the same technology as the P900, the biggest differences are the wattage and coverage area.
The P600 still comes with the company’s innovative full-spectrum technology, including 12-bands, ultraviolet, and infrared for 100% usable light. Along with a durable build, powerful fans, and enough wattage to replace a 800w HPS grow light, the P600 is perfectly capable of delivering massive growth for your plants. Plus, given the core coverage area, growers can expect this panel to light 5 to 10 plants in the “Bloom” setting.
Here are some basic specs of the P600:
- Equivalent to a 800-watt HPS grow light, but only consumes 345 watts of power
- Max Coverage at 18″: 6′ x 3.75′
- Core Coverage at 18″: 5′ x 2′
- LED Quantity: 200 x 3W
- Lifespan: 50,000 to 100,000 hours
- Warranty: 5 Years
If you loved the P900 but didn’t quite like its price tag, the Advanced Platinum Series P600 is the next best thing. Most growers will agree that premium grows are worth the investment!
