LED Grow Light Basics

  1. How much light is too much?

    How much light is too much?
    An experiment in excessively high light levels We ran an experiment with our PhytoMAX-2 800 in a 3x3 foot tent to show what happens when plants get too much light. While some of the strains we regularly work with can handle this level of light, most plants like this 'Rainmaker' start suffering and don't maximize their yield when light levels...
  2. Original PhytoMAX Series Grow Light Information

    Original PhytoMAX Series Grow Light Information
    For almost 2 years, Black Dog LED's original PhytoMAX series of lights were the most complete-spectrum LED grow lights available. They have been superseded by the new PhytoMAX-2 lights which deliver greater than 50% more light per watt to your plants, while still keeping our UV to IR Phyto-Genesis Spectrum®, delivering unparalleled yields. For 7 years running, Black Dog LED...
  3. Common PAR Meters Understate the Intensity of PhytoMAX LED Grow Lights- Some by 26% or More

    Common PAR Meters Understate the Intensity of PhytoMAX LED Grow Lights- Some by 26% or More
    PAR lighting meters can be incredibly useful tools when growing plants, but as with any tool it is important to understand their limitations. All PAR meters are made with a sensor that counts individual photons ("particles" of light). These sensors aren't perfect though, and record some wavelengths (colors) of light better than others. Spectroradiometer-based PAR meters correct for this inaccuracy...
  4. Universal Series LED Grow Light Information

    Universal Series LED Grow Light Information
    For almost 3 years, Black Dog LED's Universal Series of lights set the standard in the LED grow light industry. They have been superseded by the new PhytoMAX lights which combine the latest in LED technology with our more than 5 years' experience designing, fixing and growing with LED lights to create the best LED grow light available. The Universal...
  5. Determining the Ideal LED Grow Light Setup

    Determining the Ideal LED Grow Light Setup
    Determining the ideal LED grow light setup for your grow depends on a lot of variables: Plant / crop: Light demands Photoperiod (day / night hours) Growing area: Size Shape Your goals: Vegetative, flowering or both? Economize vs. maximizing yield Active growth vs. maintenance By selecting the appropriate footprint coverage using our lights, you can achieve the ideal grow! Plant...
  6. How many lights can I run on a circuit?

    How many lights can I run on a circuit?
    It's important to never overload your electrical circuits, as they can overheat and create a fire hazard, or trip a circuit breaker and stop important equipment in your grow. To ensure you're being safe, you need to check what is plugged in already, and how much the circuit can handle. If you have any questions or doubts about your electrical...
  7. Increase Weight with Advanced LED Plant Lighting Technology

    Increase Weight with Advanced LED Plant Lighting Technology
    Not all LED lighting systems are the same, so it's important to do some comparison shopping before investing in a system that gives less-than-spectacular results. While LED technology has been around for a while, some manufacturers are using outdated components that simply can't deliver the performance of state-of-the-art LEDs. Older diodes don't have the wattage needed for successful grow operations...
  8. Light Cycles Explained

    Light Cycles Explained
    Many flowering plants, Cannabis among them, are what are known as "diurnal" plants—they use the cycle between day and night to trigger their growth patterns. This is important to understand when growing plants indoors so that your crop management takes this cycle into account. There are two phases to the growth of most flowering plants: vegetative and flowering. The vegetating...
  9. Grow Tents for Convenient Indoor Gardening

    Grow Tents for Convenient Indoor Gardening
    Take advantage of a dedicated grow tent when planning an indoor growing site. When growing a crop indoors, considerations include location and the ambient conditions of the room. Most homes are subject to wide fluctuations in light, heat, and humidity over the course of the day and night. The better you control the lighting, heat and humidity, the more successful...
  10. The Best Grow Lights – Fluorescent vs. LED

    The Best Grow Lights – Fluorescent vs. LED
    Compare the features yourself to pick the right light for your grow operation. Engineering and Design Fluorescent lamps work by passing electricity through a gas-filled tube that contains mercury. When the mercury atoms are excited by electrical current, they give off ultraviolet light, which is invisible to the human eye. The UV light reacts with phosphors coating the inside of...
