LED Lighting - Why and how you should use it on your crop

You may have heard of LED lighting and wondered if it’s the best solution for your plant cultivation needs. This article intends to give you more information on what LED’s are and how and when they should be used, including the benefits of using them too.

Advantages of LED’s There are a number of benefits to using LED lighting compared to other alternatives the market, which include: - Lower heat output - Lower energy usage - Long lasting Another of the benefits of LED lighting is that they are effective at producing visible light. This matters because the more light there is to be used by plants, the more they can use for photosynthesis.

LEDs Last Longer
It has been found that LED’s can outlast the incandescent or fluorescent lamps and it is claimed that they’ll provide 250,00 to 100,000 hours. The reason they last so long is because they are ‘solid state’, which means they contain no gas or vacuum components. 

LED’s are Heat Efficient
Whilst they are a firm favourite of growers, sodium lamps emit a lot of heat, which makes LED’s a great alternative. Managing the temperature in a grow room is a key component of a successful grow, so reducing the heat from your lamp is one of the easiest ways to make controlling temperature simpler. This is particularly useful if you’re growing in an area of restricted space such as a grow tent, where removing heat is often more difficult. Plus, as there’s a lower amount of heat emitted, you can place LED lights closer to your plants without fear of them becoming too hot and making the most of the light available.

LED’s are Available in Different Colour Spectrums
As plants need different colour spectrums of light to grow it’s a real benefit that that LED’s are available in different colour spectrums to satisfy the needs of plants at different stages of growth. You will frequently find that there are LED’s which have more Blue light, which are perfect for propagation, whilst others have additional Red light making them suitable for the flowering stage. The Street Light Range of LED’s have a Dual option, which allows growers, particularly those who are conscious of lowering their costs. A Dual spectrum LED allows growers to provide Red and Blue light to their plants so there’s no switching in the middle of the grow. It is though recommended that for improved yields you should use specific light spectrums at the point your plants require them.

When are LED’s Best Used?
LED’s are a great alternative to other light sources such as HPS and metal Halide, but to get the same amount of light output as those, you’d need a lot of lights, which makes them expensive, although you would likely see a reduction in your electricity spend. So, there are some occasions which they may be better suited for use. Which are:

1) As a supplemental grow light. You can add extra light at little cost with an LED. Perhaps you need extra Red light to help in the flowering stage. An LED could help.
2) As a propagation light. If you’re looking to cultivate a plant from seed or cutting, LED’s offer a lot of Blue light with low levels of heat, making them perfect for propagation.
