Indoor Growing Tips From the Experts
  • KEEP ENVIRONMENTAL TEMPERATURES IN THE RANGE OF 70°-80°F (lower temperatures = slower
    plant growth) you should also monitor the root zone temperature. When switching from a traditional plant
    lamp to our LED growing light it may be necessary to add room heat or even a heat mat under your
    plants. Plants grow slower with less blooming when their environment temperature falls below 70° F.  If
    gardening without any sunlight- hybrid systems are recommended for maximum growth rates. (read

  • LOOK OUT FOR OVERWATERING! (less heat from the light source = less water loss to evaporation)
    over watering will slow root development, which will slow and stunt growth. Over watering will also cause
    nutrient uptake issues (you are feeding your plant right?). Aeroponic and hydroponic systems will reduce
    your chances of over watering.  Water plants once, then let them run low on water. This will establish the
    water usage for your plants when using LED plant lights versus natural sunlight or traditional grow lights.
    Maintain this new watering schedule.  Keeping the root medium water saturated, equals no need for plant
    to develop a larger root system, which equals stomata closure, slow and stunted growth, and symptoms
    of over watering. (For indoor growing- using a small amount of high heat traditional lighting such as metal
    halide bulbs will help water to evaporate.)(read more...)

  • For plants grown indoors without direct exposure to natural sunlight, or traditional high intensity lights,
    most growers find that running the LED lights 24 hours a day will produce superior results without
    negative effects.   Some plants require a dark period every 24 hours to stimulate late season blooming
    or fruiting. Check on the Internet or with a local nursery to find out if your plants require this treatment. If
    so, be sure to provide total darkness for 1-8 hours each 24 hour period during late season growing.

  • Use a more porous medium, which will provide more oxygen to roots, giving a higher plant metabolism.

  • In commercial growing, monitor your CO2 levels.  LED lights emit a large amount of absorbed light
    energy, which may require slight augmentation of CO2 levels (typically 300-500 PPM).  Remember that
    although the LED grow lights may not appear bright to you- the wavelengths provide an intense light
    source for your plants.

  • Start with a lower amount of nutrient (400-600 PPM) or 1/2 the recommended amount.  On fruiting plants:
    reduced photoperiod, equals plant stress, which equals more flowering.

  • If your plants are grown indoors, without supplemental light, some plants such as tomatoes may benefit
    from the addition of a single GE 60 watt soft-white light placed anywhere in the room with the plants. This
    provides a boost in some wavelengths of light which will encourage fruiting.  If there is no natural lighting
    available, LED/HPS (or metal halide bulbs) in hybrid systems are recommended for some applications.

  • Remember to follow the recommended hanging distance from your plants as determined by the model
    you are using.  Too close will stunt growth, too far will cause stretching.  When raising or lowering the
    LEDs, move them a few inches at a time and allow time to transition before moving again.

  • If you’re using the “professional” type LED grow light product, you may have noticed that one or more of
    the LEDs in each light cluster appears to not be lit. This is perfectly normal for this advanced product.  
    Light comes in many wavelengths.  Humans can only see a very limited range of light wavelengths. The
    advanced technology used in our products, and in particular the professional product, uses a very wide
    range of light wavelengths. Over 60% of the light emitted for LEDs in gardening is not visible to the
    human eye. Plants have a preference for light wavelengths humans can’t see. Why do most plants look
    green to us? It’s because the plant is reflecting the wavelengths of white light (mostly yellow and green
    light), and absorbing the rest of the light wavelengths.
     These tips come from proven grower experience and should be followed when possible to
insure success with our growing light.  Information applies to both the use of individual LED
grow lights, and light bars mounted in multiple bar arrays.  These tips apply to general gardening
as well as aeroponic and hydroponic systems.  They are techniques you may already be using.  
Now you need to develop these techniques with 90% less heat in your system.

The light emitting diodes (LEDs) used in this product are very high
intensity. Never look directly into the light at close distance, or for long
periods of time.
