Some of the links in this post are affiliate links. All opinions remain my own.
Fluorescent lights are nothing new to cannabis growers.
In fact, they were the most widely used lights just a few years ago.
After all, they are cheap and easy to get.
Later, growers began using them as supplemental lights when more powerful lights like LEDs and HIDs entered the market.
You can still use fluorescent lights like the T5 from the beginning to the end of the growing cycle.
It’s only a matter of choosing the right strains.
So, let’s take a look at some of the best fluorescent grow lights for cannabis, and why you might want to add some to your garden.
Quick Top 5 Best Fluorescent Grow Lights:
What Are T5 Lights?
Traditional fluorescent lights don’t produce enough bright light for plants to grow.
But, T5 lights are more efficient and well suited to grow plants.
A single unit consists of several fluorescent lights to help increase the efficiency.
Since they are inexpensive and effective, you can replace LED or HID lights with several units of T5 lights, but we recommend that you use them as supplemental lights.
How to Use Fluorescent Lights Effectively?
Fluorescent lights may not be the first choice for many growers.
However, they can help you grow fantastic plants if you know how to use them.
But, they are PERFECT for clones or seedlings.
For example, a seedling that has just popped out will appreciate the lack of powerful lights baking them.
You need to help the seedling slowly adjust to its environment.
This is when T5 lights can be your savior.
Another advantage of T5 lights is that they can be hung very close to the plants.
You cannot hang HIDs or LEDs close to the plants without burning them.
And once you burn the plants, you can kiss your harvest goodbye.
But, with T5s, you can rest easy.
The light emitted from the fluorescent lights is effective only up to a foot anyways.
So, if you place the plants too far away, the light is pretty much useless.
To make the best use of a T5 light, you can choose strains that tend to grow small.
There are a variety of strains that are small yet powerful.
They can also help to send focused light to your colas to help them dense up.
Here’s a video that explains T5 fluorescent lights in detail.
What are the Benefits of T5 Lights?
There are several types of fluorescent lights including T8 and T12.
The numbers indicate the size of the bulb.
While T8 and T12 lights are bigger, T5 lights are the smallest.
However, T5 fluorescent lights are the still best among them all.
They are designed specifically to produce high amounts of light.
Also, the best part of owning a fluorescent light is that your electricity bill won’t shoot through the roof.
They are low powered and don’t become hot quickly.
In simple terms, T5 lights are best for someone on a tight budget.
Fluorescent lights aren't very powerful.
However, there’s a new range of T5 fluorescent lights that produce a better output with higher lumens.
