Providing the adequate amount of light to indoor plants is just as important as watering the plant. An indoor gardener cannot grow strong and healthy plants without reproducing the magic of the sun with grow lights. Not enough light coverage will result in weak and uneven plant growth, while too much lighting can stunt plant growth and waste electricity. However, choosing the right amount of light with Light Emitting Diode grow lights can be very simple.

If you are entering the world of indoor gardening, you might be wondering how to choose the right LED grow light for your growth. How much lighting do you need for your particular grow area? LED grow lights are the best choice for efficient indoor growing. The technology in LED grow lights differs greatly in power consumption, light spectrum, and heat output than other grow lights such as metal halide, high-pressure sodium, t5s and plasma lights.

In this article we will assist you in choosing the right LED grow light-saving you time, money, and helping you to a perpetual growth of high quality plants.

Your choice of LED Grow Light will depend on:

  1. The Type of Plants you’re growing
  2. The size of your Indoor Garden
  3. The distance of Light from the Plant

#1- Plant types you’re going to grow

Before you pick the LED grow light for your indoor garden, you should keep your plant in focus. Different plants utilize different intensity of light and have different lighting requirement for photosynthesis. Many grow lights are used for growing illegal type of plants (you can probably guess what that is!) from seedling through vegetative growth, to flowering and harvest.

There are some great LED grow lights, such as the one from Dorm Grow that are made with G8LED technology. These lights allow the growth of the plant from seeding to flower and result in healthy plant growth and quality flower formation. It is important to increase the red wavelengths during the flowering phase of plant growth to mimic the natural changes during outdoor seasonal growth.

#2- The Area of Your Grow Garden

The size of your indoor area for plant growth specifies the wattage you will require. There are different charts available which determine area coverage of particular lamps. A rule of thumb is to have about 25 watts of actual power draw per square foot of growing area. There are different sized lights based on wattage which provide coverage for different sized grow areas. Choose the correct amount of light based on the specifications of coverage area for a given light.

#3- The distance of the Grow Light from the Plant

Your plants will utilize the energy from the grow light to photosynthesize and grow. Light intensity is greater near the light and deceases as the distance increases. With traditional lights the challenge is keeping the light close enough to the plants without burning them as metal halide and high-pressure sodium bulbs generate an immense amount of heat. The advantage of LED grow lights is their efficient use of power and very low heat output. Although the LED grow light will not burn plants, bringing an LED light too close to the plant can hinder its growth, as the light intensity can be too strong for the plant. LED grow lights should be no closer than one foot from the plant and can be as high as four feet above the plant canopy.

You can determine if your LED grow light is too close to the plant by observing the tips of the leaves. If you observe white bleaching this means that the lights are too close and the intensity is too strong for the plants. Raise your light a few inches at a time until your plant recovers. You can also expand the area of your indoor garden by adding additional lights or by adding a light mover-if you are setting up a large grow space. This will prove to be effective in cost and production.
