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 his grow light output in Lumens they are only telling
you how bright his grow light will appear to you and light your room, not how well it will grow your plant.
The most accurate unit of measurement for comparing grow lights is the micro Einstein, 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.
What type of soil should I use for my plants?
It is always best to use a more porous planting medium when gardening with led grow lights. A loose soil that doesn't compact
will allow more oxygen to reach the roots, increasing plant metabolism and growth. A porous medium will also help avoid
problems associated with over watering.
How warm should I keep my plant growing area?
The energy efficient line offered by Light Earth Design will not heat up 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
F to 80 degrees F 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 the LED Grow Master Gro-Bar?
Absolutely! Plants grown under the Light Earth Design plant lighting systems 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.
How often and how much should I fertilize?
Your plants will need fewer nutrients when grown under led grow lights. Start with a lower amount of nutrient, approximately
400-600 PPM, or around 1/2 of the amount recommended by the manufacturer.
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?
Is it Safe to look at the lights in your led grow light?
The light emitting diodes (LEDs) used in the product supplied by Light Earth Design 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
typer 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.
