Which grow lights for plants produce less heat?
When they are growing plants indoors,
horticulturists face some unique challenges. Whereas growing plants outside
exposes them to lots of air movement and cool nighttime temperatures, growing
them indoors limits the amount of carbon dioxide present and maintains more or
less a steady temperature. Why do we say that this is a challenge? Well, the
ideal growing temperature for most plants ranges from 70-75°F.
However, some high wattage grow lamps produce excess heat, and in a short time
can raise the room temperature to over 85°F, the threshold
when serious damage starts to occur in the plants. In this article, let’s have
a look at which grow lights for plants produce less heat, and thus protect your
As we mentioned in the introduction, when a
grow lamp is rated for high wattage, a lot of the energy is wasted in the form
of heat. So, the key to buying quality grow lights for plants is to look for
efficient arrays that have lower energy consumption. LED grow lights fit perfectly into this
category. Because they are more energy efficient, they produce less heat. What
does that mean for the plant? LED grow lights for plants can be mounted without
raising the plant’s temperature. This means that the plant will transpire (lose
moisture) more slowly, which means that it won’t need to be watered as often.
Whengrow lights for plants consume a large
amount of wattage, they raise the temperature of a growing area. This has to be
counteracted. With most grow lamps (like High Pressure Sodium and Metal Halide
lamps) the only solution is to purchase some sort of a cooling apparatus for
the grow area. One family in Alaska who sells basil locally used to run a large
air conditioner in order to keep their greenhouse at proper temperatures when
they were using conventional grow lights¹. This added up to a significant
expense for the farmers, and cut sharply into their profit margins. When they
began using LED grow lights for plants, however, they saw an immediate
stabilization of the temperature, and they no longer needed to have the air conditioner
running in order to save their crops.
What’s more, using the proper grow lights
for plants eliminates the unnecessary expenses of buying complicated cooling
equipment and the cost of running it. That’s not all. The noise generated by
these cooling mechanisms and the need to give them proper maintenance can
really affect whether or not a grower enjoys what he does. LED grow lights for
plants come with tiny built-in fans to keep the array itself cool, so that they
will not overheat and burn out.
Using LED grow lights for plants is the
best way to guarantee a high yield of your crop and to maintain an adequate
temperature in your growing area. While all grow lights for plants promise
results, only LED grow lights for plants get them. Try some today, and you will
see how much easier they make your life and how much better your plants grow.
