When you want your plants to grow, LED lights can help
What are some of the most important things
to keep in mind when setting up your indoor growing area? Although we would all
like to be idealistic and say that the quality of the product is all that
matters, we have to be realistic and admit that cost is a significant factor.
The cost of the equipment, the plants themselves, and of course, the lighting,
can easily raise the initial investment into the hundreds if not thousands of
dollars. However, when you are preparing to grow, LED lights make a lot of sense
economically. Although the initial investment may be higher than HPS (High
Pressure Sodium) and MH (Metal Halide) lamps, over the long run they will save
you a lot of money. Let’s do some dollars and cents comparisons to see why when
you want your plants to grow, LED lights are the key.
We’ll start with a simple comparison: when
you grow, LED lights provide something that High Pressure Sodium and Metal
Halide lamps cannot: duration. For a basic 1000W High Pressure Sodium system
(which includes the ballast and a cooling unit to offset the heat generated by
the lamp) you can expect to pay about $200. How long will this lamp last? Most
sellers recommend that they be replaced every year (which, if used 18 hours a
day, amounts to approximately 6,500 hours of use). How does this compare with
helping your plants to grow using LED lights?
A comparable LED array would include about
230 diodes at 3W (we have already discussed why LEDs are more energy efficient-
because they only produce the light wavelengths that are actually needed by the
plants). How long will this array last? The minimum
lifespan of this array is 50,000 hours.
At the same usage as the example above (18 hours per day) we can see that a LED
array would only need to be replaced after about 2,777 days, or roughly 7.5
years. But remember that 50,000 hours is the minimum, as many LED arrays can easily last for double that amount
of time. When you want to grow, LED lights are the best choice.
To grow, LED lights like the one we
mentioned are a somewhat bigger investment initially. An array of 230 LEDs at
3W each will cost about $1200. However, with the combined monthly energy
savings (about 30% the cost of a High Pressure Sodium lamp) and the longer
duration, it just makes financial sense to go with the LED array. When you want
to see your plants grow, LED lights are the most practical and environmentally
Once you have decided that the best way to get the fresh food and plants that you want is to bring them in your house and simply watch them grow, LED lights can help to make any project a success. They provide the highest level of light intensity, ensuring that the leaves of your plants receive what they need, when they need it. And when you grow with LED lights, your pocketbook will be much happier. LED grow lights give you lower energy bills now, healthier plants in the near future, and great performance for the years to come.
