T5 grow lights are fluorescent lights, that give off all the wavelengths of light that HPS and MH grow light kits offer. Many growers are growing smaller plants from the seedling stage to harvest using T5 grow lights.

They come in a variety of shapes, sizes, and strengths. The T in T5 stands for the shape of the lamp or tube and the 5 represents the diameter of the bulb — so ⅝ of an inch in this case.

Are you looking for the best T5 grow lights? If so, there are hundreds of choices out there. So we’ve compiled this list of top quality T5 grow lights. It doesn’t matter if you’re a seasoned gardener or a newbie with limited experience, we’ve got you covered.

T5 grow lights have many advantages over high-intensity discharge (HID) grow lights, including: they’re more energy efficient, they’re easier to use, they aren’t as expensive, and they’re safer.

But before you rush out and buy a T5 grow light, you should understand this: T5 grow lights aren’t all built alike. While there are T5 grow lights that are 100% perfectly designed for horticulture, others are more “fun” in nature (like novelty lights, fish tank lights, and even Halloween lights).

T5 grow lights are the best types of lights to grow any kind of plant, from vegetables to the most delicate flowers.

Frequently Asked Questions (FAQs)

What is the best T5 grow light?

There are quite a few good T5 grow light brands; it comes down to the best light for your needs.

A spectrum of light with a small number of colors (such as 3000K–4000K) would work well for small plants. Plants in the vegetative stage need a higher level of red light, and plants in the flowering stage, a higher level of blue light. If the blue and red lights are closer in value, it is a standard 6000K grow light.

If you are growing bigger plants, you will need higher wavelengths in your light to encourage them to grow higher and a higher level of blue light. A bigger plant requires a bigger heat sink so that you will need bigger T5s.

The Hydrofarm Agrobrite FLT24 T5 Fluorescent, 2 Foot, 4 Tube Grow Light System is a four tube fluorescent T5 grow light with a full-spectrum® for optimal plant growth. This is a perfect option for you if you want a full-spectrum light with flawless construction and reasonably priced.

How far should my T5 lights be from my seedlings?

The distance of your light source from your plants is a very important consideration. Your plants need to receive light evenly. You wouldn’t want to have them grow tall and lanky on one side of their stem and short and squirmy on the other. It’s not good for the plants and makes them much harder to weed and train.

To ensure proper lighting, add a bit of extra distance between your light source and your plants. This extra distance results in less intensity, and therefore requires your plants to grow extra tall and lanky. The trick with grow lights is to get as much light as possible while still keeping it gentle.
The T5 fluorescent grow light distance for seedlings should start by hanging the light 6 to 10 inches from seedlings.

Are T5 lights good for growing vegetables?

If you are growing vegetables indoors, you need to consider two things: getting the right spectrum of light for each variety and getting the right spectrum of light on the plants at each crucial growth phase.

The different kinds of plants that are grown indoors require their own set of spectrum. If your light doesn’t have the spectrum, your plants won’t either. You need to provide them with the right light, which can be achieved through grow lights.
The T5 light tubes are fluorescent light bulbs. These bulbs are very efficient and can produce more light per watt than any other bulb. These offer a lot of red and blue light, which you need during the veg and flowering stages of growth.

How many watts is a T5 grow light?

In general, the higher the wattage of light, the more electricity it consumes. This is why light efficiency matters. The most important factors to consider are the spectrum, lumens, and PAR.

A full spectrum or broad spectrum grow light for plants contains all the lighting wavelengths of natural sunlight.
The wattages for standard T5 lamps are 14, 21, 28, and 35 watts. The high-output T5 (T5 HO) lamps are available in 24, 39, 54, and 80 watts.

Conclusion

T5 grow lights have become a popular lighting choice, and for a good reason. Unlike more traditional lighting, T5 grow lights are versatile and don’t take up a lot of space. They also use less electricity than traditional lighting setups, and you can get a full grow room setup for a fraction of the cost. Whether you’re a beginner looking to test the waters, or an experienced farmer looking to upgrade, there’s a T5 grow light out there you’ll love.
