The Pros and Cons of a T5 Grow Light

The Pros

T5 grow lights are extremely helpful with growing plants indoors. Besides being ideal to use indoors, they also have many other benefits. One is that they are much less expensive compared to other grow light options. This makes T5 grow lights good for beginners to use or for those who don’t want to invest in an expensive light system.

These grow lights are also much cooler compared to other grow lights due to them being energy-efficient. You won’t have to worry about them overheating or burning your plants. Also, due to their energy-efficiency they help to save money on your electric bill.

The Cons

While T5 grow lights have many benefits you should be aware of some things about them. One is that you need to make sure your T5 grow light has a red light. This red light will help with the flowering stages of your plants. Some of the T5 grow light models don’t have this color light so it’s important that you check to see if your model does. Otherwise, your plants might not bloom well.

These grow lights also have a shorter life compared to other light options. T5 grow lights only run for about 20,000 hours. This might seem like a very long time, but when it comes to growing plants it isn’t. You’ll have to be aware that you might end up having to invest a little in T5 grow lights. However, as mentioned above, they are affordable options.

The other downside about T5 grow lights is that you need to have a ballast with one of these lights. While most T5 grow lights have a ballast built into them, not all of them do. A ballast will help to prevent the lights from overheating which could damage your plants. If you find that your grow light doesn’t have one of these built into it, you’ll have to invest in a separate ballast yourself.

Why a Ballast is Important to Have in a T5 Grow Light

Fluorescent lights can overheat sometimes which can burn the leaves of your plants. To help prevent this from occurring, ballasts are usually built into T5 grow lights. Ballasts are specially designed to help prevent overheating in fluorescent lights which can stop possible damage from happening to your plants. Also, because fluorescent lights sometimes flicker, ballasts can prevent them from doing so. Flickering can surprisingly impact your plant’s growth, so it’s important that a ballast is incorporated into your T5 grow light.

What’s the Best Wattage for a T5 Grow Light?

As you’ll find with many of the T5 grow lights in this article, they each have various wattage amounts. So, what’s the difference between them?

There’s actually a big difference between them which could impact how your plants grow. You usually want to look for a T5 grow light that works at 6400K.

However, you want to make sure that the wattage is also at least 2700K-3000K. This wattage range is usually where the red spectrum in the lights will be which is a crucial color when growing plants.

Overall, the wattage amounts will help to show how they will help certain growth stages with your plants. A stronger wattage will mean that it can help with all stages while a lower one usually means that it will work best with only some.

Things to Keep in Mind Before Using a T5 Grow Light

There are quite a few things to keep in mind before using a T5 grow light. Here is more about what you should look for and consider before investing in one of these lights.

The Power Cord

The power cord is extremely important to look at when searching for a T5 grow light. You’ll be hanging this light up which means you need to make sure the power cord’s length is long enough to easily reach a nearby outlet. If not, it could make it very difficult for you to use your T5 grow light. Extension cords can help, but they could make it more difficult for you to reach your plants. They also might overheat a little which could cause some problems with your grow light.

Check the Hanging Height

One of the most difficult aspects about grow lights is their hanging length. How high should it be? Should it be closer or farther away from my plants? The hanging height depends on how strong your T5 grow light is. If the light has a very high wattage you want to make sure it is hanging much higher from where your plants are to prevent them from burning. If the wattage is on the lower side, you probably want to keep it a little closer to your plants so they stay warm. As your plants grow you’ll eventually have to adjust the hanging height so they aren’t growing into the light.

Check the Weight

T5 grow lights can be a little heavy so you always want to check how much they weigh before you hang their structure over your plants. Most of these grow lights weigh on average about 15 lbs. but there are many models that weigh much more (and less) than this amount. Be sure to check the weight and make sure that the structure you are hanging it from is able to handle it.

Look at the Bulb Type

It’s important to look at the bulb type of a T5 grow light. The bulb type will show how high a wattage it will have. You usually want a strong wattage which will help to keep your plants warm. However, a strong wattage also means more energy is needed. This could lead to a higher electric bill for you. Be sure to look at the bulb type to make sure that it won’t be running too high or you might end up paying quite a bit with your electric bill.

Check for a Red Light in the Bulbs

A red light helps with the flowering in plants. If your bulbs don’t have a red light spectrum in them, your plants might be alive but they won’t flower. A red light is vital to have in order to have a plentiful harvest.

Make Sure You Have Replacement Bulbs

Eventually, your T5 grow lights will burn out. When this happens, you want to make sure you have a replacement bulb on hand. This will allow you to immediately replace the burned out light so the warmth of the grow light doesn’t diminish.

Look for Accessories

T5 grow lights can be used with many useful accessories. Two accessories you should consider using with your grow light are rope hangers and timers. Rope hangers will help to keep your T5 grow light secure while it is hanging and make sure it doesn’t accidentally slip and fall on your plants. A timer can help to make sure that the grow lights are on and off at a certain time so they don’t shine too much on your plants. It can also help to tell you when you need to water your plants.


Growing plants can be easy thanks to T5 grow lights. These lights are specially designed to help with all stages of your plant’s growth. While these lights are energy-efficient and affordable you do need to keep a close eye on some certain aspects of them, like making sure they have a ballast. All of the models in this article are some of the best on the market and are ones you should definitely consider using for your plants.
