First, when it comes to growing with LED lights it’s important to know what the light you are using is made of. The wattage of LED, the angle of the lens, and the total wattage consumed by the light. These factors paired with the intensity of the light will determine the best method to follow when using your new LED grow light.
Determining Color and Power of LED Grow Lights
Let’s start with the type of plant and light intensity you desire first. Vegetative types of plants like lettuce or spinach do not need as much intense light to grow. If you are growing flowering and fruiting plants you will need a very intense light with a strong emphasis on red colors. Flowering plants can be hard to grow with LED grow lights if the light uses very cheap 1w LEDs and a wide angle lens (120 degrees) which makes the light spread out and drastically reduce the intensity of the light. Flowering plants should have as much light as possible and usually do much better under all 3w LEDs with a 90 degree lens. With this type of high intensity LED grow light, flowering plants are grown best with the light hung about 18 inches above the plant canopy.
If you have cheap low wattage 1w LEDs with the traditional 120 degree lens you will want to hang the light no higher than 6 inches above the plant canopy in order to produce results. If you have less than 1w/LED of in your lights then I would suggest only using them for vegetative growth, seedlings and clone transplants. These cheap low wattage LED grow lights are not all they are claimed to be and usually will result in a frustrated grower with little to show for a harvest.
Using Light Movers with LED Grow Lights
Another factor in growing with LED grow lights is side light and light movers. LED grow lights are directional lights that focus their light in one direction. If you add some florescent lights to the side of your garden you can see proportional benefits in harvest without much of an increase in your wattage or cost per unit of harvest. Light movers with high powered LED grow lights work great to increase the number of leaf sites that receive intense light and will allow your plants to fill out more evenly. Remember though to check your lights specifications regardless of side lights and light movers because if your wattage or lens angle is weak you will need to be much closer or not use those cheap lights on your flowers at all.
