Buyer’s Guide: The Basics and Tips

Before buying lights for your cannabis, you should have a basic understanding of what kind of product you’re looking for. Besides getting the hang of replacing lightbulbs and ballasts, there are various characteristics that make up the light of a certain type. In this section, I’d like to introduce some vital information for your consideration, as well as some basic terms.

What are T5 grow lights?

iPower GLT5XX4X2


T5 grow lights are one of many different-diameter lights that you can equip your plant-growing tent with. First of all, they are T-shaped, which makes them fit only for a certain type of fixture. Second of all, their size comes to ⅝ of an inch, which is the exact diameter of the bulb juxtaposed to 1 inch.

Types of T5 lights

T5 lights are the third generation of fluorescent lights that are mostly equipped for indoor use due to their local and focused light emission. Though there aren’t different types of products based on its material or use, there is a significant difference between the wattage. To get the best T5 to grow bulbs, it’s essential to see the difference between output and input power and its use:

  • 14-35W lights are used for minor illumination since they produce a sufficient yet limited amount of light. They are perfect for small cannabis patches or seeds that have only recently been planted.
  • 24-80W lights are much stronger, and their light output is considerably higher. Some of them come in handy when maintaining medium-sized or bug-sized cannabis. Also, they offer a wider coverage area that can help illuminate greenhouses and even enclosed farms.

What is fluorescent lighting?

Fluorescent lighting is lighting produced as a result of a chemical reaction inside the bulb. There, a blend of gases and mercury-infused vapors come into contact, creating bluish light. Later, it interacts with chemical phosphorus powders, which leads to white daylight.

Another important part of fluorescence is ballast. It’s used to reduce the current input that comes through the bulb. This prevents the lights from overheating and, consequently, from producing sparks. Also, it makes T5 fluorescent grow lights rather safer and more stable than those which have regular illumination reactions.

T5 vs LED grow lights, and why we choose fluorescent lighting

Both lights use different yet quite similar approaches to producing light. LED lighting is relatively newer to the market, and it uses fewer chemical reactions to provide illumination. When current goes through the bulb, it interacts with a special chip-like device that lights up and gives off light. There are many chips like this inside that when combined, produce a sufficient amount of light. Also, they are known to give off much less heat than other kinds of bulbs.

Despite these characteristics being good for humans, they aren’t as good for plants. We choose fluorescent light because of the heat. Cannabis and many other plants require not only light for their photosynthesis but also warmth. Therefore, in a competition T5 vs LED grow lights, T5 wins.

What to look for when choosing the best T5 grow light for your grow

First, search for the power in Watts. Depending on the stage and type of cannabis you’ve got, you might want to consider different T5 lights before picking the right one. You will need a weaker set for beginnings and a stronger one for a larger plant.

Second, you’ll need some longevity. Normally, it depends on the fixture and bulb material. You’re going to want steel for the fixture and aluminum or aluminum-infused alloys for the bulb. Combining these features, you might get yourself a reliable set of lights that will not damage your cannabis nor break down easily.

Are T5 grow lights good?

Yes, they are, but it depends on the purpose. When it comes to growing cannabis and other heat-demanding pants, then it’s a perfect fit.

Which is better: LED or T5?

Both of them are good enough, but I’d prefer to use T5 since they have already proven more than useful in my experience.

What is the best light to grow plants under?

Doubtlessly, the best light you can get for your growing is sunlight. However, the closest you can get to it indoors is to use grow lights that reproduce the intensity and heat, just like T5 lights.

How many watts does a T5 grow light use?

The wattage may vary depending on a specific product. Normally, grow lights are recommended to be in the range of 14 to 54W.

The Sun Isn’t a Must Anymore
