How does the Lumen output of the LED Grow Master Grow Light compare to other grow lights?

Lumens and Lux are measurements of how bright a light source appears to the human
eye. Since the human eye is most sensitive to colors plants don’t need, and least sensitive
to colors plants prefer, Lumens can’t be used to accurately compare the plant growing
capability of grow lights. If a grow light manufacturer rates the grow light output in
Lumens- they are only telling you how bright the grow light will appear to you and light
your room, not how well it will grow your plants. The most accurate unit of
measurement for comparing grow lights is the microEinstein, which measures how many
photons of light strike an area per second. But while this is a much better way to estimate
a lamp’s plant growing ability than Lumens or Lux, it is still very difficult to directly
compare two different types of grow lights. All grow lights except the LED Grow Master
grow light emit large amounts of light plants don’t use very efficiently, so including that
light output in a light’s plant growing measurement is misleading.

Can I buy the LED Grow Master grow light from my local store?

LED Grow Master products are available from several Internet and catalog retailers. If
your local supply store is not carrying LED Grow Master products, ask them why not.

What type of soil should I use for my plants?

In general, it is always best to use a more porous planting medium. A loose soil that doesn’t compact will allow more oxygen to reach the roots, increasing plant metabolism and growth.

How warm should I keep my plant growing area?

The energy efficient LED Grow Master grow bar will not heat your growing area like
traditional grow lighting products. In cooler weather you may need to compensate for
this by raising the temperature of your growing area to between 70 degrees Fahrenheit
and 80 degrees Fahrenheit if you wish to accelerate the rate of plant growth. If you can,
monitor the temperature of your plant’s root zone as this can also affect the rate of plant
growth.

Should I water my plants differently when using LED Grow Master grow bars?

Absolutely! Plants grown under the LED plant lighting system use much less water than
those grown under conventional (i.e. hot!) grow lights, and so need to be watered less
frequently. Be very careful not to over water your plants, and check to see that the soil is
drying a bit before watering them again. The time between watering will vary with plant
species. Over watering will slow root development, stunt plant growth, and cause
nutrient uptake issues. (continued…)

How often and how much should I fertilize?

Your plants will need fewer nutrients when grown under the LED Grow Master Gro-Bar.
Start with a lower amount of nutrient, approximately 400-600 PPM, or around ½ of the
amount recommended by the manufacturer.

My plants aren’t flowering like I expected, what can I do?

LED Grow Master plant grow lighting is very gentle to your plants. In some cases you
may need to introduce some “stress” to help your 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

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
be totally dark at night. Check on the internet or with a local nursery to find out the
preferred light/dark period for the plants that you’ll be growing.

Is it safe to look at the lights in a Gro-Bar?

The light emitting diodes (LEDs) used in this product 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 growing, monitor your CO2 levels. LED 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 or LGM5) you may notice
that one of the LEDs in each light cluster appears to not be lit. This is perfectly normal
for this advanced product. Light comes in many flavors called 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 version, uses a very wide spectrum of
light output. Over 60% of the light emitted from this light bar is not visible to the human
eyes. 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 reflection the components of white light (green and
yellow), and absorbing the rest of the light.
