Why do plants require such powerful lights to grow indoors?
Plants have evolved over billions of years into very efficient factories for converting sunlight and nutrients into food. To help your plants thrive indoors you need to provide them with light of sufficient quality and duration to enable them to accomplish this. Natural outdoor sunlight can be up to one hundred times brighter than artificial indoor light. Although the human eye may easily adjust between indoor and outdoor lighting conditions “in the blind of an eye” it is an entirely different matter for plants. They still require light energy similar to what they have evolved under. What is the difference between Fluorescent and HID? Fluorescent lamps are good for starting seedlings and rooting cuttings, but do not have enough intensity to sustain aggressive growth in plants in the later stages of life. Sodium and halide High Intensity Discharge (HID) bulbs emit a very bright, intense light with a full color spectrum for optimal plant growth. If you plant to grow vegetables or fruits
