ECO Farm 30W LED Grow Light Bar VS Atreum Lighting UVA Light Bar, 30W (2-FT)

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.

Why Use LED Grow Strips?

In short: flexibility. You can install these lights anywhere and in any position.

LED light bars give indoor growers great coverage and utility. LED light bars are one of the top options for indoor growers due to their utility and coverage.
Whereas fixtures can be bulky and difficult to fit into tight spaces, light bars are generally longer and more slender overall. This means that they fit great into high-density production facilities like most vertical farmers are using, and the increased length of the bar makes coverage more manageable and dispersed.

That makes them perfect as supplemental lighting or as the primary lighting for small veg or clone rooms. Used as supplemental lighting, you can easily place them on the walls of your room to light your plants from the sides or on the floor to get light on them from the bottom.

One great use is to line the sides of the tent where the walls meet the floor and/or the ceiling with strip lights. In a veg/clone/seedling room, you can use several strips of cool white light above the plants. They give off very little heat, so you can hang them very close, allowing you to grow in tiny spaces.

You can easily stack several shelves of seedlings or clones on top of each other and simply tape LED strips on the bottom side of each shelf to light the plants below.

Why Are LED Strips Better Than Fluorescent Bulbs?

LED strip have four big advantages over fluorescent tubes:

• They take up less space, so you can put them anywhere and they won’t get in the way
• They use half the power, saving you money
• They last longer, saving you money and the hassle of having to change bulbs more often
• They emit less heat, meaning they can hang closer. That said, these strips are generally a bit less powerful (especially the flexible tape-style ones)，so you’d mainly want to use them as supplemental light. If you need more power, I recommend T5 grow bulbs.

ECO Farm 30W LED Grow Light Bar

Features:

ECO Farm  LED Grow Light Bar has professional red and blue spectrum. 630 nanometer red light is the peak wavelength of photosynthesis and light effect, very suitable for blooming and fruits. 460 nm blue light is suitable for plants that synthesize chlorophyll. So this is the best part of the blue and red chips, blue light + red light = encourage plants to reach the plant growth stage.

The shell of the led plant light is made of aluminum, which has excellent heat dissipation, no fan, no noise, and solves the problem of insufficient sunlight in the winter greenhouse.

Wide range of uses-aqueous culture and soil culture. It can be used in gardens, flower exhibitions, bonsai, greenhouses, seeding, greenhouse cultivation, water-soluble breeding, pipeline cultivation, etc.

Atreum Lighting UVA Light Bar, 30W (2-FT)

Features:

Atreum Lighting UVA Light Bar is a 30watt Uv grow light that is made with 5m 385mm ultra ligh-quality Uv- LED diodes, which increase your plant yields and makes your plants resistant to fungal infections. UVA light is proven to trigger increased resin prouctin during the final stages of medcinal plant growth.

This waterproof UV grow light can withstand humid and wet environments. The passive cool design of the light makes it energy-efficient and cuts down your electrcity costs.

And it is suitable for both hydroponics and indoor plants, mainly used for micro-greens and small plants.

Red and Blue Lights in LED Grow Lights

Effect of Red Light on Plants
Red light is radiation with wavelengths between 620 and 750 nm. These wavelengths are within the visible spectrum and red light has a pronounced effect on both photosynthesis and flowering. However, plants grown under only red light may not have the desired characteristics. For example, plants grown with only red light can have skinny, stretched stems (“etiolation”) with fewer leaves. This is particularly true if the plants are young.

Effect of Blue Light on Plants
Blue light is radiation with wavelengths between 450 and 495 nm. These wavelengths are within the visible spectrum and blue light has a pronounced effect on photosynthesis, plant height, and flowering. However, blue light is less effective than red light for driving photosynthesis. In addition to playing an important role in photosynthesis, blue light is well known to suppress stem elongation (“stretching” or etiolation). Plants grown with blue light are usually shorter and have thicker, and denser leaves compared to plants grown without blue light.

Ideal Combination for LED Grow Light Strips – Red and Blue Light
Red light should be used in conjunction with blue light to increase photosynthesis and plant size. Although a plant can be grown using just red or blue light, most plants have faster growth with a broader spectrum of light. Red light can be used in conjunction with blue light.
Both red and blue light are more efficiently absorbed by photosynthetic pigments compared to other regions of the spectrum. The red-blue combination allows for a faster rate of photosynthesis than either red or blue light alone. Compared to red or blue light alone, the red-blue light combination also increases plant size, leaf number, leaf size, and chlorophyll content. Depending on the plant species, the ideal ratio of red: blue light varies.

Conclusion

All in all, LED light bars are an excellent way to give your crops the light they need to grow in higher densities. While there are many options on the market with unique features and a range of power requirements, one thing is constant: you must be mindful of how much heat they generate. Unlike LED fixtures, this particular form factor is not equipped with active cooling elements such as fans and growers will need to understand how to manage excess heat in their growing environment.
Remember, unmitigated heat increases the potential relative humidity of the growing environment, which leads to increased disease incidence and other plant issues like tip burn. At an extreme, it will cause drought stress and tissue death so make sure you know how to manage heat loads or find a light that will do that for you!
