The Top 5 Best LED Grow Lights for Weed

 

Introduction

LED lighting is the most advanced tech in grow lighting today, and can end up saving you a lot of money in the long run. In years past, weed was grown indoors using High Pressure Sodium or HPS lighting. HPS or HID lighting is expensive to maintain because bulbs must be replaced yearly and burn out very quickly.

While many beginning gardeners prefer to buy an out of the box LED grow light setup, there now is a more flexible, and often cheaper option for growing plants indoors — the LED grow light bar. These strips of LED lights are perfect for folks with a bit of do-it-yourself knowledge who want to build their own LED plant stand.

Types of LED Grow Lights

LED grow lights come in a variety of forms. Learning about the most popular ones can help you choose a suitable type for your indoor garden.

Spread-Style
Spread-style LED lights have many small individual lights spread out over their entire surface area, which makes them effective in providing light to a large number of plants. The two main subcategories of spread lights are spider-style and quantum board.

Quantum board lights use a large number of small LEDs spread out over a relatively large, flat surface area. They use full-spectrum white LED diodes and typically feature passive cooling, allowing the plants to be placed immediately under them without the danger of too much heat emission.
Spider-style lights feature multiple LEDs on narrow “arms” in an open bar design rather than on a solid board. These tend to be more expensive than quantum board lights.
Chip on Board (COB)
Chip on board (COB) lights feature a number of tiny LEDs placed close together on a single chip, resulting in a single powerful point of light. While the center point of the area they cover receives optimal lighting, they don’t offer the same level of widespread, equal coverage as spread-style LEDs.

Since they’re so powerful, COB lights often emit more heat than other types of LEDs and may require the use of fans to cool down the area. They use full-spectrum white LED diodes and provide deeper canopy penetration than do spread-style LEDs.

Traditional
Traditional LED grow lamps are usually compact, making them a good choice for small spaces. They use LEDs that provide medium power and typically feature multicolored LEDs that cover the full spectrum of color frequencies, unlike white LEDs. This gives their light a colorful appearance that indoor growers might or might not like.

Why use LED grow lights?

There are some great reasons to use LED grow lights:

You have more control over your plants
The right temperature is critical to ensuring your plants don’t get burned or wilt. Optimal growth means the right balance of warmth and cool. LED lights produce less heat and don’t get as hot to the touch, and are therefore far less likely to damage your plants.

LED grow lights also give you more control over wavelength and even wattage. This allows you to manage the light intensity and wavelength your plant will receive at each stage. Many come with dimmer switches and other precision controls. LEDs also allow you to better plan for unique grows and provide better coverage by configuring multiple lights.

They run cool and eliminate the need to ventilate
No one needs the added expense of a separate ventilation or cooling system. LED grow lights give you intense light without nearly as much heat. No cooling or ventilation system means an additional energy savings.

Easy to install and portable
Installation is typically just following a few steps, very simple. Made with modern materials, these lights are easily portable and relatively compact.

Many LED grow light models are small, and can be configured together. This allows you to combine them to cover larger areas and unusual spaces.

More energy-efficient and cost-effective
LED grow lights have long life spans — between 50,000 and 100,000 hours, or 7 to 8 years on average, typically. LEDs are also more energy-efficient than any other type of light based on output and power drawn.

What Should I Know Before Buying LED Grow Lights?

How to choose the best LED grow light: there are so many important factors. Here are the ones that are most critical.

The Needs of the Plant
Light cycles can seriously impact your plants’ growth and potency. Some need full light from a high-intensity source, and others get dried out or burned with too much, so make sure you know what you need from the outset.

A full spectrum LED grow light will help ensure maximum growth. Ideally this kind of light will have red and blue spectrums, as well as IR and UV light. (If you don’t grow from seed or germinate your seeds outside you might be okay with just red and blue light, but full spectrum is always preferred.) Better still, you’ll be able to control which spectrums it emits, when.

Energy Efficiency
Full spectrum LEDs are also more energy-efficient, typically. They are durable, usually run cool without additional fans, and cost less in electricity. Your grow lights will need to be operating for 18 hours every day at times.

The higher their output (wattage), the more power you’ll be using, but not proportionately. In other words, if you need 1000 watts instead of 500, you still won’t see twice as much power consumption.

Control and Customization
Remember that you’ll be changing the lighting cycles depending on the growth stage to ensure that your plants thrive:

Seedling stage: 16 hours on/8 hours off
Veg stage: 18 hours on/6 hours off
Flowering stage: 12 hours on/12 hours off
Size and Spacing of Your Grow Room
Don’t fight with manufacturer specifications, especially when it comes to coverage area. Your LED grow light system simply has to cover the right space for your plants.
