The use of grow lights as a substitute for sunlight to improve plant growth and yields goes back many years. But quite recently LED technology spilled over into this field causing no end of a stir. So let’s examine what all the fuss is about and sift reality from opinion.

One thing that LED lighting technology can lay undisputed claim to is being the most effective means ever devised for converting electricity into light. Unlike high intensity discharge (or HID) lamps which create considerably more heat than light per watt of electricity, LED lights waste very little and thus also run cool to the touch.

The second key difference between LED and HID lamps is that the former can be made to target very specific parts of the spectrum whereas the latter emit light broadly across most of the visible spectrum. Since plants absorb most of the light they need for photosynthesis from just two narrow zones in the spectrum, HIDs not only waste energy creating heat, they also waste it creating useless (to plants) light.

What is an aerator? If you are wondering what an aerator is, you are not alone. In fact, there are probably more people who do not know what it is than the number of people who do. Basically, an aerator is a tool that you use to keep your lawn healthy. You use it to turn the soil and create holes in the top portion of soil. This will allow the soil (your lawn) to get the water and air to the grass and plant roots therefore keeping them healthy.

What are some of the functions of an aerator? Aerators can do a lot of things, and are like little multi-taskers. The following are some examples of what they do: 1. Creates holes in soil 2. Separates dead grass tissue from healthy soil 3. Helps oxygen to better reach soil 4. Helps water to better reach water 5. Creates more space for roots to grow
