Our LED Grow Lights are recognized by the international standard that designates products fit for use in wet and humid conditions. Few companies that make grow lights are granted this certification and we designed our lights with this in mind as most indoor gardens and commercial greenhouses have wet and humid environments creating challenges for gardeners. Our IP65 housings make clean up easy and you can foliar spray your canopies without worrying about damage to the lights internal components.

Peace of Mind:

Light plays one of the most important roles in growing great plants, but too many growers take it for granted, leading to underwhelming yields and unspectacular results. Our LEDs gives you the lighting you need, whether you’re growing commercially, for pleasure, or both.

NATURE'S HELPER LED grow light is guaranteed to maintain 90% or better light output for 3 YEARS with regular use because we want to ensure your satisfaction with great plants and a healthy harvest.

How To Hang Our LED Grow Lights
Correctly hanging grow lights ensures proper coverage and safety. Fortunately, we make it simple to do. Your standard rope ratchet rated at 40 lbs. will easily hold your lights, which weigh 7 to 26 lbs. depending upon the model and options chosen.

Please note that most rope ratchets have carabiners too small to fit our lights, which is why we recommend using the attached “S” hook as it makes it so much easier to hang the light. You can use the additional bracket to hang the light at an angle of your choice from a fixed position or take it off and use the center ring to hang the light.

Placement of Lights
Lighting fixtures work best when shared. By placing lights in close proximity to each other, plants that would otherwise be on the periphery receive more light from both lamps, thereby increasing their productivity in what is known as cross illumination. Please review the footprint that works best for your application of light.

One widely used method to determine a lamp’s intensity over time is the Inverse Square Law. As a general rule of thumb these results can be found in most lighting scenarios and is only being used here as a guideline. Using different reflectors that focus light into a narrow region such as our 90* reflector will change the outcome of these values greatly as will our 120* reflector.

Once your lamp is properly secured to the ceiling, you must determine the appropriate hanging height above your plant canopy. Light intensity diminishes at an exponential rate; therefore, the closer you hang your light, the greater its effect will be. With LEDs, plants can touch the lamp without suffering heat damage to the plant. However, the light is too intense for most plants to be any closer than 24” of our light source

Coverage Areas
Raising the light higher above your plants increases the light coverage, but also decreases the light intensity. Therefore, it is important that you find the appropriate balance between intensity and coverage. Each LED grow light has been rated to cover a determined area.

90° reflector: For vegetative and mother plants, the light can cover a 4’ x 4’ area 18″ above the canopy.

Why Full Spectrum LED Grow Lights?:

Why Your Plants Need Full Spectrum LED Light?

The key benefit of our LED grow light is its remarkable ability to mimic natural sunlight by emitting a full spectrum of light. Red and blue light wavelengths activate photosynthesis, but are not the only wavelengths plants need. Oversaturating your plants with only red and blue wavelengths actually causes them to go dormant, leading to under produced plants.

By using LED Light with full spectrum, which appears as white light, it induces your plants to undergo natural photorespiration. While that will force them to work harder, it also leads more efficient nutrient intake. You end up with sturdier plants, healthier growth, and increased yields.
