Tomatoes and LED Grow Lights

How close should I mount my light bar above 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 even without the infrared light.

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. Always
remember the balance between light, heat, and CO2 levels.

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. The LGM5
LED grow light emits 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.

About LED Grow Lighting

Ten LGM3 LED grow lights use
less electricity than a 100 watt grow
light.

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" (LGM3) or 18"
(LGM550) call for proper close
mounting suggestions and a
diffuser.
