• 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 traditional grow lights 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.• DON’T OVER WATER YOUR PLANTS (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?).• 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.
• On fruiting plants: reduced photoperiod, equals plant stress, which equals more flowering.
• Use a more porous medium, which will provide more oxygen to roots, giving a higher plant metabolism.
• Water plants once, then let them run low on water. This will establish the water usage for your plants when using LED grow 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.
• 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).
• Start with a lower amount of nutrient (400-600 PPM) or 1/2 the recommended amount.
• 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.
• Remember, it doesn’t look like much light to you, but it is a lot of light energy to your plants.
• 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 from our product 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.

• 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.
