How close should I mount my led grow lights to my plants?
  • Mounting recommendations are written on the back of each bar according to the model you are using.  If
    mounting any of our led grow lights closer than 12" you must angle them in toward the canopy as
    opposed to mounting them directly overhead.  Placing a single bar closer than 12" directly above a plant
    can quickly cause damage .

My plants aren't flowering like I expected.  What can I do?
  • LED grow lighting is very gentle to your plants.  In some cases you may need to introduce some "stress"
    to help you plants bloom.  For example, turn your lights on for fewer hours each day, or allow your plants
    to dry out a little more than usual between watering cycles.  If your plants are grown indoors without
    supplemental light, some plants, such as tomatoes, may benefit from the addition of a single 60 watt light
    placed anywhere in the room with the plants.  This provides a small amount of invisible infrared light,
    which some plants find beneficial.

How long should I operate my lights each day?
  • Remember, most plants need to sleep just like we do, except plants prefer that the room e totally dark at
    night.  Check on the Internet or with your local nursery to find out the preferred light/dark period for the
    plants that you are growing.  One of the characteristics that we are learning is that if you are growing
    under LEDs only (no sunlight or other artificial light) you may be able to use the led grow light for 24
    hours and see up to 40% more growth.

Is it safe to look at the lights in your led grow light?
  • The light emitting diodes (LEDs) used in our led grow light are very high intensity.  Never look directly
    into the light at a close distance, or for long periods of time.

Are there any special considerations for commercial growers?
  • In commercial operations you will want to monitor your C02 levels.  Our led grow lights emit a large
    amount of absorbed light, which may require slight augmentation of CO2 levels (+300-500 PPM).

It looks like one of the LEDs in each cluster isn't working.  Is this normal?
  • If you're using the professional type light bar (Model LGM3/LGM5) you may notice that one of the LEDs
    in each cluster appears to not be lit.  This is perfectly normal for this advanced product.  Light comes in
    many different wavelengths.  People can only see a very narrow range of light wavelengths.  The
    advanced technology used in this product, and in particular the professional type versions, use a very
    wide spectrum of light output.  Over 60% of the light emitted from this led grow light is not visible to the
    human eye.  Plants have a preference for the light that we cannot see.  Why do most plants look green
    to us?  It's because the plant is reflecting the components of white light (green and yellow) and absorbing
    the rest of the light.

Close Mounting of LED Grow Lights
You will find many pictures showing LED grow
lights directly above plants such as the one above.
 These pictures exist because many people do not
recognize the lights as grow lights without a plant
below them.  Most of our clients use their LEDs
three or more feet above the plant canopy which
makes it nearly impossible for a close-up photo
that shows both the plant and the LEDs.
 Some
companies actually suggest you put the LEDs
directly above the plants using the assumption that
because they are not hot- they will not damage
your plants.  The focused wavelengths emitted
from our led grow lights are too intense for any
plant at this distance.   If bars
must be mounted
closer than 12" (LGM1) or 18" (LGM3,LGM5) call for
proper close mounting suggestions.
