Fluorescent grow lights have been seen as inferior products for a very long time because the conventional T12 and T8 bulbs had a very low lumen-to-watt ratio, making them inefficient.

With the new high lumen output T5 grow light systems, fluorescent lights have come a long way to being a sustainable option for indoor growing.

Most T5 fluorescents grow light system are capable of delivering an adequate amount of lumens, allowing you to grow seeds, flowers, cuttings, as well as house plants indoors.

The new T5 lights are also known to be highly energy efficient. They draw less wattage of power to function optimally. They even have the potential to emit the same wavelengths of light as HPS grow lights.

However, not all T5 fluorescent grow light systems are up to the task. Here is our roundup of grow light reviews for the choices that come highly recommended by most growers for indoor grow rooms.

Things to consider

T5 grow lights have the smallest diameter compared to similar types, such as T12 and T8. But they have a superior watt-to-lumen ratio.

So, they aren’t just brighter, but also more efficient than the alternatives. They have a better life cycle compared to incandescent bulbs.

Now, choosing the ideal T5 grow light system that will help your plants grow healthier requires you to consider the following.

What Fluorescent Lights Should You Buy?

When fluorescent lights first appeared in the market, a lot of people were using them in conjunction with incandescent lights for indoor growing.

There are actually lots of different fluorescent lights out there. But, there’re some that just outperform others as far as lumen production is concerned.

When you are looking at buying T5 grow lights, you must ensure that you are buying grow lights. There are lots of fluorescent grow light bulbs for all sorts of different applications in the market.

The ones for growing plants typically have a very specific Kelvin rating, which may range from 3,000K to 6,500K.

Consider Light Color Temperature (Kelvin Rating)

The color temperature of any light source is a measure of how blue, yellow, or white it appears. The system of measurement used for rating the color temperature of T5 grows lights is Kelvin.

We see light differently than plants do. Your plants use the photosynthetic active response part of the light spectrum for different stages of growth.

T5 grow lights (fluorescent tubes) with a Kelvin temperature rating from 3,000 to 6,500 K are best for indoor gardening, such as growing marijuana.

Lower color temperatures are usually easier on the eyes and ideal for home use. However, T5 grow lights with lower Kelvin rating may do a poor job of illuminating your plants.

Therefore, it is very important to pay attention to that Kelvin rating in order to ensure that you’re getting the exactly as much light for the right time in your plants’ life cycle.

The fluorescent lights are also classified as very high output (VHO), high output (HO), and normal output (NO).

We recommend tubes that are rated as high output (HO). These bulbs will provide you with the best of both worlds in terms of Kelvin and usable spectrum your plants need.

What Kinds of Plants Are You Growing?

T5 fluorescent grows lights are more efficient in warmer temperatures, and they are certainly more reliable than T12 and T8 for most of your indoor growing.

They generally emit light in a range that is a little bit friendlier for most vegetative plant production.

However, they seem to be only suitable for plants that don’t require lots and lots of lumens or light with a variable spectrum.

According to our findings, T5s will give you the best results in the vegetative growth stage. In fact, you will get dense vegetative growth and more color.

What about the Coverage?

You cannot just go picking any good quality T5 grow light. You must consider your size requirements with respect to your grow tent, grow house, or stand racks.

Mostly, the bulb configuration will help you establish whether or not the grow light system will be sufficient for your indoor garden.

The most common bulb configurations that you will come across are 1-Tube 2-Tube, 4-Tube, 6-Tube, 8-Tube, and 12-Tube.

Usually, a 1-Tube or 2-Tube bulb configuration is suitable for growing a few small plants. However, a more elaborate garden may need a 4-Tube or higher.

Final Words

These lights still have limits on how much heat and light they give off. Therefore, they are particularly recommended for young plants.

Unlike high-powered grow lights, a high-quality T5 grow light system is very unlikely to burn sensitive cuttings or seedlings.

Their less intense spectrum is also suitable for planting a variety of different herbs and vegetables.

However, T5s may not be as convenient and reliable as LED lights, or a viable option when you want to venture in big production environments.

If you are thinking about a commercial farm, you should think long and hard about installing T5 fluorescent grow lights over something like LED grow lights.
