How can you pick the best LED grow light?
When you decide that it is time to invest
in a LED product for your growing needs, you will be astounded at how many
people are willing to sell you their version of the product. They all advertise
that they offer the best LED grow light, and most of them are being sincere.
They honestly believe that their product is just as good as every other on the
market. However, the reality of the matter is quite different, as not all LEDs
perform the same. In fact, during the past two decades that horticulturists
have been using LEDs,there have been some mixed results. The problem is not the
technology or the theories behind it; the problem lies in the quality of the
lamps themselves and how they are used. In this article, we will have a closer
look at how to pick out the best LED grow light for your needs.
Finding the best LED grow light isn’t just
about price. While, naturally, you want to find a bargain, the old adage “you
get what you pay for” cannot be ignored. By definition, the best LED grow light
is one that gets results, namely, healthier and more productive plants. One of
the key elements involved is called light intensity. This refers to the actual
amount of light that is hitting the leaves of the plants. What factors can
influence light intensity? Well, think of an ordinary garden hose. When the
water flows out of the end of a hose, uninterrupted, an incredible volume of
water goes to the exact same spot. However, if you put your thumb over the end
of the hose, the water gets dispersed, and it falls over a larger area.
Something similar happens with the different designs of LED grow lights that
are available, although the best LED grow lights avoid the more serious
The best LED grow light will amplify the
intensity of the light that is emitted by the LED. It does this by means of a
concave lens mounted under the silicone-wrapped chip that is inside each LED.
The angle of this lens is what determines how much the light is dispersed. A
very wide lens will result in the light being dissipated long before it reaches
the leaves of your plants. As a result, you will have to move the LED array
closer. However, in so doing, the temperature of the plant will probably rise
significantly, causing it to lose more moisture, which can lead to permanent
damage. For this reason, the best LED grow light for you is one that is built
with a narrower lens angle. This will permit the LED array to be mounted at a
better height (distance), which will in turn allow the light to reach the plant
without raising its temperature.
As we have seen, there are very slight differences between the LEDs sold online. But the best LED grow light is one that finds a balance between all of the extremes. It does not disperse its light, and it does not produce unnecessary light (yellow, orange, UV…) that the plant doesn’t need anyway. The best LED grow light will also probably not be the cheapest. But remember that you are thinking long term, and about the overall health of your plants.
