Benefits of using the best LED grow lights for weed

Best LED grow lights - Marijuana under LED grow light1The best LED grow lights for weed offer so many benefits.

Here are the most important reasons to choose the best LED grow lights for weed:

  • Space saving design: LED grow lights do not require a lot of space when compared to other types of grow lights. Nor do LED grow lights need to be supplemented by other equipment, like a cooling system. With these comparatively small grow lamps, you can maneuver more freely through the grow room. You don’t have to worry about extra equipment and cooling systems that take up a great deal of space. With better access to your marijuana plants, you can provide better care and attention.
  • Energy efficient: The best LED grow lights for weed are extremely energy efficient, and far more efficient that traditional forms of indoor lights. LED grow lights are preferred because they have the power to produce a great deal of light without drawing much power. In the long run, this is an enormous saving on your electricity bill.
  • Long Lifespan: With the best LED grow lights, you will be able to grow for years without having to replace your indoor lighting system. The best LED grow lights run for between 50,000 and 100,000 hours. They are hardy and durable compared to other types of grow lights.
  • Low running temperature: The best LED grow lights for weed run extremely cool. The temperature of the grow room is crucial for the success of your marijuana grow. LED grow lights have an advantage in that they run at a temperature that is only just warm to the touch.
  • Intense light generation: The best LED grow lights generate considerably more light per watt than fluorescent or HID lighting.
  • Built in cooling: The best LED grow lights come with small built in fans. This, in addition to the fact that most LED grow lights run relatively cool in any event, means that grow rooms that run on LED grow lights only require extra ventilation in exceptional circumstances.
  • No ballast: LED grow lights do not flicker or need a ballast.

All experienced marijuana growers know the problems and hard work it takes to setup a grow room with HID lighting. HID lights and ballasts are heavy, need a lot of support to hang and require frequent replacement because the lights decrease in brightness each year. With the best LED grow lights these issues are a thing of the past.

While the initial investment in the best LED grow lights you can afford may be a substantial, you will more than recoup your outlay over time in cheaper running costs and better marijuana yields.

Full spectrum lights are the best LED grow lights

Growing marijuana indoors - LED lightsThe best LED grow lights on the market are full spectrum LED grow lights because they mimic the sun’s light spectrum and intensity.

Full spectrum LED grow lights result in greener, lusher marijuana plants with healthy buds. The best LED grow lights come with specialized lenses that increase light penetration by pointing light directly on the marijuana plants. The result is better yields for the same amount of light.

The best LED grow lights ensure your plants get what they need in both the vegetative and flowering stages by providing full spectrum light that includes a wide range of colors (including blue, red, white, and ultraviolet light) at the correct ratios.

Understanding how full spectrum colors work in the best LED grow lights allows you to really take charge of your marijuana grow to ensure the best results ever.

Understanding the color spectrum of the best LED grow lights

Natural sunlight features the entire spectrum of light. The best LED grow light manufacturers use only certain kinds of LEDs that produce a specific color and provide your marijuana plants with exactly what they need.

Here are the different colors and how they relate during the marijuana plant growth cycle:

  • Blue LED lights: Suitable for for the vegetative growth stage, but not helpful during the flowering stage. Blue is in the mid-400nm range and creates tall, leafy plants during vegetation. When used during flowering it can cause bushy plants without many buds.
  • Red LED lights: Suitable for budding and flowering. Red is in the 600-640nm range and too much red light during vegetative growth produces unhealthy plants.
  • White LED lights: These are very contentious LEDs. There is no clear cut answer on whether they are beneficial to plants at all. At best white LEDs assist humans to see inside of the grow room. If only red and blue LED were used, it would be impossible properly or at all.
  • Ultraviolet LEDs: Ultraviolet light is not always used, but it is well worth experimenting with it. Growers started using with ultraviolet LEDs, because they noticed the higher potency of equatorial strains of marijuana, despite the plants being exposed to the most damaging ultra violet rays of light. Research has shown that ultraviolet light in short bursts increases THC production in cannabis plants.

To ensure healthy growth, your marijuana plants need the right blend of light at the right time. It is relatively simple to replicate the right wavelengths for indoor plants.

For the optimum color ratio a LED panel should be as close as possible to:

  • 55% Red LEDs rated at 660nm
  • 20% Red LEDs rated at 630nm
  • 15% Blue LEDs rated at 470nm
  • 10% Blue LEDs rated at 425nm

You cannot simply use one set of red LED grow lights and one set of blue LED grow lights. This setup will fail because it does not provide your marijuana plants the full range that they would receive in nature. When grown outdoors, the kind of light a plant receives fluctuates as time progresses and the seasons change. The best LED grow lights replicate natural sunlight inside your grow room and are a crucial part of a successful harvest.

How to select the best LED grow lights for weed

Best LED grow lights - Marijuana under LED grow lightsThe best LED grow lights for weed produce precisely the correct light spectrum for your marijuana plants, and do not waste energy radiating light in an unneeded spectrum.

We recommend LED grow lights that have a wide range of wavelength options available. You can adjust the best LED grow lights to provide only the needed light spectrum.

Here are the most important factors to evaluate when choosing the best LED grow lights for your setup:

  • Coverage: This is the first aspect to consider when selecting the best LED grow lights for weed. Coverage is the area the LED grow lights can reach.
  • Wattage: Wattage typically refers to the wattage of equivalent non-LED grow lights that the LED grow light can be used as a substitute for. Non-LED lights include High-Pressure Sodium (HPS), Metal Halide (MH) and High-Intensity Discharge (HID) lights (see more below).
  • Full spectrum: We recommend you choose full spectrum LED grow lights that you can use throughout the marijuana growth cycle.
  • Angle of the LED lens: Take note of the angle of dispersion of the LED grow light. Generally, a bigger angles mean more coverage, while the smaller angle mean less dispersion and more intense direct light.
  • Built in cooling: The best LED grow lights have a built in cooling system. This is very important for the lights longevity, as well as the overall temperatures in the grow room.
  • Price: Last, but by no means least, the price of the LED grow light is also a factor. The price tags of the best LED grow lights vary vastly. Aim for the best you can afford. You will recoup your outlay in saved electricity and increased yield.

Determining wattage and coverage of the best LED grow lights

There are no real standards measuring LED output in wattage. The number of watts a LED grow light actually draws from the wall is not the same as the advertised wattage. This is misleading.

A LED grow light advertised as 300 watt means that the light can be used it as an alternative for other types of 300 watt grow lights. The real wattage of the light could be as low as 140 watt because LED grow lights use far less electricity. When determining the wattage needed for your grow room, it is easiest to work with the advertised wattage.

The optimal wattage range is between 50 and 80 watt per sq ft. For example, a 3 x 3 ft grow tent (9 sq ft of grow space) requires at least 450 watt of LED lighting (9 x 50 watt). You can accomplish this either by purchasing a single 450 watt (or more) LED grow light or by daisy chaining a number of smaller LED grow lights together.
