While the diameter of T5 light bulbs is set at 5/8′′, the fixtures that they come in vary in size, making them a versatile choice for your grow room. T5 light bulbs. If you require a specific length and number of bulbs, you can almost certainly find them.

In T5 grow lights, the temperature of the bulb can be adjusted in two ways. Each has a specific role to play in the growth of plants at every stage.

Microgreens, seedlings, and mature plants can all benefit from 6,500K bulbs. Kevin's best-selling T5 bulb type is the Kevin T5.

Using 3000K bulbs encourages plants to bloom and produce fruit.

Reflector Style

Apart from sizing, there are two primary types of T5 grow lights: rectangular reflectors and gull-wing ones, both of which use the same light source. While I like encased reflectors and near proximity to plants, if you have to set your lights higher, the gull-wing form may be an option.

Your Budget

Your Existing Lights

Adding T5 lighting to your current grow lighting arrangement is a consideration if you currently have grow lights. You should do a preliminary estimate of the overall cost and light output of all of your lights before making a purchase. Unless you want to replace all of your old lights, this is a smart idea.

The Color Temperature of the Bulbs

A T5 light fixture might have replaceable bulbs so check to see what is included in your system before purchasing. Fluorescent bulbs shine in the vegetative stages of growth, thus you should use bulbs suited for this stage. Pick up some flowering bulbs while you're at it, too.


What are T5 Grow Lights?

Plants cultivated indoors or in areas where there is insufficient light might benefit from T5 grow lights, a type of fluorescent bulb that produces artificial lighting. The letters "T" and "5" stand for "5/8 inch tube diameter," respectively.

The T8 and T12 fluorescent tubes are just a couple of the options available. But the most popular and efficient of the three is the T5 model.

Veggies and seedlings have been grown using T5 grow lights for decades.

How far do I hang T5's from plants?

The distance between your light and the canopy should be at least 6-8 inches. A T5 grow lamp can boost this to 12-24 inches depending on how powerful it is.

Despite the fact that T5 lights produce less heat than HIDs, it's vital to remember that they do produce heat. It is also true that the more bulbs a light has, the more heat it produces. It is critical that you raise your plants to keep them safe from the sun's rays.

Remember that if you raise your light too high, it will cause your plants to stretch. Plants and crops are damaged as a result of this practice. As a result, monitoring the height of your T5s above your plants is critical to ensuring that they receive the proper quantity of light.

How long do T5 grow lights last?

Just over two years' worth of use is possible with T5 fluorescent grow bulbs. Their reflectors and ballasts, on the other hand, can last anywhere from three to four years before they need to be changed.

When the internal ballasts or connections on a T5 grow light fail, you'll have to replace the entire reflector, as opposed to other grow lights that may be replaced in pieces. T5's are more expensive to replace than any other grow light, so keep that in mind when you're growing with them.

Are T5 lights energy efficient?

T5 fluorescent bulbs, with the possible exception of LEDs, are among the most energy-efficient options available. If you're producing seedlings, greens, or herbs, you'll save a lot of money by using LEDs instead of HID, HPS, or MH bulbs, both in terms of energy expenses and in terms of venting away surplus heat.


It's important to take into account recurring costs before purchasing the best T5 grow lights for your needs. A good rule of thumb is to think about how many seasons you'll utilize a product before making a purchasing decision. Investing in a step-up product will save you money on future parts and bulb replacements if you plan to grow with the light for at least three seasons. There have been many generations of keen indoor gardeners who have relied on T5 grow lights for sprouting seedlings and keeping houseplants alive through the winter. Your new T5 grow lights will be a lot of fun once you have them installed.
