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 led grow lights.  If a grow
    light manufacturer rates his grow light output in Lumens they are only telling you how bright it will appear
    to you and light your room, not how well it will grow your plants. The most accurate unit of measurement
    for comparing plant lighting 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 of led grow lights 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 LED Grow Master 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 out 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.

Our led grow lights should not be measured in
Lumens or Lux.  These are "white light"
measurements for grow lights such as HPS,
MH, fluorescent, and incandescent lighting.  
When SolarOasis introduced led grow lights to
the grower in 2002, (SolarOasis holds the first  
patent for led grow lights) all measurements of
light energy were based on white light
products.  However, white light products
produce a lot more energy than plants can
use from 380nm (UV) to beyond 880nm (IR).  
Our led grow lights focus on the wavelengths
between 400nm (blue) to 700nm (red) known
as Photosynthetically active radiation.  
Eliminating these extra wavelengths found in
traditional lighting allows led grow lights to last
much longer using far less electricity.
