Why Do Plants Need Grow Lights?

Before we address grow lights, you must know that all plants need light. This is basic biology that everyone is taught in primary school. Plants need light, which comes to them naturally in the form of sunlight, to grow bigger, taller, and stronger. Plants make use of the energy of the light to break down the sugars in their body and to provide ‘food’ to all their parts. Furthermore, this light also helps with the process of generation of chlorophyll which is important for plants. 

Now when you are growing your plants outdoors, all is well thanks to the sunlight. However, when you grow them indoors inside a grow room or a grow tent, you would need a grow light. The most important function of a grow light is to replicate the natural light of the sun. Sunlight is made out of lights of different wavelengths which is replicated in these grow lights to provide the best quality lighting to the indoor plants. Having a grow light is like having a mini sun in your grow tent

What are T5 LED Grow Lights?

In order to understand T5 LED grow lights, you first need to know that when “T5 Lights” are usually referred, people might be referring to Fluorescent Lights. However, T5 LED lights are different and the word points to a where specific kind of LED lights which fit in T5 ballasts and fixtures. To understand what T5 LED lights are, you will first need to understand what T5 lighting actually means –

Anytime you are talking about lighting systems and you hear ‘T’ lights, it is actually referring to the shape of the light. Here, T stands for Tube/Tubular shape. Now you would usually here lamps such as T3, T5, T8, and T12. This number that comes after the T that denotes the shape shows the diameter of the light in reference to an eighth of an inch. Sounds complex? Let us simplify it.

A T3 light basically has a diameter of ⅜ inches. Similarly, a T5 lamp has a diameter of ⅝ inches. Then comes the T8 lamps which are basically 1 inch in diameter (8/8). T5 lamps are about 40% smaller in size when you compare them with T8 lamps. Now when you look at T12 lamps, it means they measure 12/8 inches which is 1½ inches in diameter. The biggest difference lies in what is inside the tubes. 

If you get a standard T5 fluorescent light, the lighting inside the tube is fluorescent lighting while if you get a T5 LED grow light, the lighting inside the tube is LED light. This distinction is important for the growers to understand. Here, all your fixtures feature T5 setup but the light that is inside them is an LED grow light. This is beneficial for growers as they can use the existing setup while getting LED lighting, which is usually considered better than fluorescent lighting.

You must always know exactly how much area the grow lights you are buying can cover.

When it comes to the most important metric before buying any grow light, power consumption surely ranks on top. You need to know what is the exact amount of power that the grow light is drawing from your power socket. Many growers would confuse this with the number that is written with the light – a 1000W grow light does not really consume 1000W from your power socket! Always check the details for the exact consumption details.

3. Brightness and Intensity of Light:

Measured in lumens, always look up for how bright the light is. Usually, the higher the luminosity the better it is for your plants. 

4. Cost and Warranty

While it doesn’t even need to be mentioned, cost is indeed very important can be the make-or-break factor for many growers. Similarly, make sure you’re getting the light that gives you the longest possible warranty period.
