Before we present our top 5 T5 grow light picks, though, let’s go a little deeper regarding what T5s are and what they have to offer you and your plants.

What Are T5 Fluorescent Grow Lights?

Closeup of T5 grow light bulbs.T5 grow lights are fluorescent lights, and they come in a variety of shapes, sizes, and strengths. The T in T5 stands for the shape of the lamp (or tube) in a grow light fixture. Meanwhile the 5 represents the diameter of the bulb — so ⅝ of an inch in this case.

Though T5 grow lights may seem simple, these fixtures actually have the potential to give off all the wavelengths of light that HPS and MH grow light kits offer and even more. That’s why so many growers are either growing smaller plants from the seedling stage to harvest using T5 grow lights.

So with that said, are there any noticeable benefits to using T5 grow lights on your plants? There absolutely are! Let's dive into what those benefits are!

Why Use T5 Lights in Your Grow Room?

Compared to other lights, T5 grow lights have some truly unique advantages. While they may not be as strong as CMH and HID grow lights, or as intense as LEDs, you’d be surprised at what T5s have to offer.

  • T5 grow lights are efficient. Overall, T5s are going to save you money. The energy usage of these lights is about 50 percent of what HIDs use — that means a lower monthly electric bill. In addition, replacing components in a T5 grow light like reflectors, bulbs, and ballasts costs less than it would to replace those same parts in an HID or LED fixture.
  • T5s are highly customizable. You can adjust your light fixture with different bulbs depending on your plants’ needs. There’s virtually a T5 grow bulb for every occasion — from deep blue for vegging to light red for flowering, as well as bulbs that offer UV light for improved photosynthesis (among other benefits). Really the only lights that come close as far as customization is concerned are LEDs, and we all know that those aren’t exactly cheap.
  • Though not as intense as other lights, T5 grow lights are still very efficient. If you’re wondering how T5s can be so efficient despite their lighter intensity compared to other grow lights, it’s actually quite simple. Typically, you’ll want to hang your T5 light fixture closer to your plants — due to their lower heat output, you don’t need to worry about T5s burning or bleaching your plants like other grow lights would if you were to hang them too close.

T5 Grow Light Upgrades

PowerVEG T5 4' Multi-Color Pack (case of 24)T5 grow lights are awesome because their spectrum can be customized. With these lights, you can swap out each bulb and replace it with a different wavelength of your choice. In fact, you can essentially make an all-vegging, all-flowering, or combination light that you can use from the seedling to harvesting stages by just swapping out a few bulbs. It’s literally that simple.

  • Blue wavelengths boost foliage production. If you want a good harvest, you need to start with exceptional flowers. You can’t get those, though, unless you’ve got the foliage to help them grow. With more blue wavelengths than a standard 6400k bulb, your plant will get the stimulation it needs to grow big leaves and strong branches.
  • Red wavelengths will give you better flowers. Plants need plenty of red wavelengths to ensure they continue to grow big flowers and provide heavy harvests. With an extra bit of red added to a T5 grow kit’s lighting cycle, your plants will give you flowers that rival an LED’s harvest.
  • More UV means stronger plants. Most T5 grow lights don’t have a lot of UVA and UVB in their wavelengths — and neither do a lot of HIDs and LEDs, for that matter. With a bulb like the PowerVEG T5 54W 4' HO Tube, you’ll be able to give your fruit and vegetable plants the specific wavelengths they need for better flavors, richer aromas, stronger roots, and increased growth.
