What are Fluorescent Grow Lights?
Contents
If you’re new to indoor growing, you may be confused about which type of grow light to choose for your cannabis plants. One option that you may have come across is fluorescent grow lights. But what exactly are they? Simply put, fluorescent grow lights are a type of artificial lighting system that provide plants with the necessary light spectrum for growth. However, there are different types of fluorescent grow lights available, and it’s essential to understand their differences before making a decision. Let’s delve deeper into the types of fluorescent grow lights and how they work.
Types of Fluorescent Grow Lights
When it comes to fluorescent grow lights for growing cannabis, there are several types to choose from. T5, the most popular type, is a tube-style light that is approximately 5/8 inch in diameter. These lights are efficient, cost-effective and produce less heat than other types of fluorescent grow lights. They are also available in a variety of spectrums, including blue and red, which are beneficial for both the vegetative and flowering stages of cannabis growth.
Another type of fluorescent grow light is the CFL (Compact Fluorescent Lamp), which is available in traditional light bulb shapes (such as spiral or u-shaped). These lights are often used for small-scale operations or for providing supplementary lighting to larger grow spaces. They are also energy-efficient and ideal for use during the vegetative stage of plant growth.
The HO (High Output) fluorescent grow light is another popular option. These lights use a type of ballast known as an electronic ballast to produce more light than traditional fluorescent lights. While they are more efficient than other types of fluorescent grow lights, they can also produce more heat and may require additional cooling.
Finally, there are LED (Light Emitting Diode) fluorescent grow lights, which use LED technology to provide a full spectrum of light for all stages of cannabis growth. Although they are more expensive than traditional fluorescent lights, LED grow lights are energy-efficient, long-lasting, and produce less heat. They are also a good choice for larger grow spaces as they can cover a larger area than other types of fluorescent grow lights.
It is important to consider the specific needs of your cannabis plants and the size of your grow space when choosing a type of fluorescent grow light. Each type has its own advantages and disadvantages, so it is important to do your research to find the best fit for your particular situation.
How do They Work?
Fluorescent grow lights work by converting electrical energy into light through the use of a process called fluorescence. Here is a breakdown of how this process works:
- Electrical current: When an electrical current is passed through the gas inside the bulb, it excites the gases and causes them to emit ultraviolet (UV) radiation.
- Phosphor coating: The inside of the bulb is coated with phosphor, a material that absorbs UV radiation and re-emits it as visible light.
- Visible light: The visible light emitted by the phosphor coating is then used by the plants for photosynthesis and growth.
There are a few different types of fluorescent grow lights that use slightly different technologies to achieve this process. For example, some use mercury vapor and argon gas to produce UV radiation, while others use a mix of phosphors to produce a more balanced spectrum of light. In general, however, all types of fluorescent grow lights operate on the same basic principle of electrical current exciting gases to produce UV radiation, which is then converted into visible light by the phosphor coating inside the bulb.
Pros of Using Fluorescent Grow Lights for Cannabis
When it comes to growing cannabis, choosing the right lighting is crucial for a successful harvest. Among the different types of grow lights available, fluorescent lights have become increasingly popular due to their numerous advantages. In this section, we’ll explore some of the pros of using fluorescent grow lights for your cannabis plants.

Cons of Using Fluorescent Grow Lights for Cannabis
While there are several advantages to using fluorescent grow lights for growing cannabis, there are also some drawbacks that growers should be aware of. While fluorescent lights can be a great option for seedlings and small-scale operations, they may not be the best choice for those looking to optimize their yield potential or grow larger plants. Let’s take a closer look at some of the challenges and limitations associated with using fluorescent grow lights for cannabis cultivation.
Lower Yield Potential
While fluorescent grow lights can be a great option for some cannabis growers, they do have some cons to consider. One of the most significant drawbacks of fluorescent grow lights is their lower yield potential.
This is because fluorescent lights typically have a lower intensity of light output compared to other types of grow lights, such as LEDs or HPS lights. As a result, plants may not receive the optimal amount of light needed to produce large, dense buds.
To better understand this, let’s take a look at a comparison table of potential yields for different types of grow lights:
| Grow Light Type | Potential Yield |
|---|---|
| LED | 1-2g/watt |
| HPS | 0.5-1g/watt |
| Fluorescent | 0.2-0.5g/watt |
As you can see, fluorescent grow lights have the lowest potential yield at 0.2-0.5g/watt. This means that if you are aiming for a high-yield harvest, you may want to consider using a different type of grow light.
However, it’s important to note that fluorescent lights can still produce decent yields, particularly if you are growing on a small scale or if you are growing seedlings or clones. Additionally, if you are just starting out with cannabis cultivation, fluorescent grow lights can be a good affordable option to get your feet wet before investing in more expensive equipment.
Not Ideal for Flowering Stage
While fluorescent grow lights may have their benefits, they are not ideal for the flowering stage of cannabis growth. Let’s take a closer look at why:
| Issue | Description |
|---|---|
| Lack of Intensity | Flowering cannabis plants require high levels of light intensity to produce dense and potent buds. Fluorescent lights are not intense enough to provide the light needed in this stage – resulting in lower yield and lesser quality of buds. |
| Light Spectrum | Fluorescent grow lights emit a spectrum that lacks enough intensity in the red and orange wavelengths – which are crucial for flowering in cannabis plants. Thus, they fail to deliver the necessary wavelengths during this stage. |
| Large Space Requirement | During the flowering stage, plants tend to grow taller and wider, requiring more space and light coverage. As already mentioned, fluorescent lights need to be placed close to the plants, which means it becomes less and less effective as the plants grow. Using fluorescent lights for large plants is not economical, and the yield will be disappointing. |
| Long Flowering Period | The flowering stage is generally longer than the vegetative stage, and cannabis plants require a sufficient amount of light, correctly timed, to produce the highest quality buds. Unfortunately, fluorescent lights cannot deliver this level of intensity for an extended period, further reducing the quality of the yield. |
If you are considering using fluorescent lights for growing cannabis and hoping to maximize yields, it is essential to switch to other, more powerful lighting methods, such as high-intensity discharge (HID) lights or LED lights, during the flowering stage. However, if you only grow for personal use or interested in small-scale operations than fluorescent grow lights can still provide a cost-effective solution.
Need to Be Placed Close to Plants
When it comes to using fluorescent grow lights for cannabis, one of the cons is that they need to be placed close to the plants in order to be effective. This is because fluorescent grow lights emit less intense light compared to other types of grow lights like HID or LED lights.
Placing the lights too far away from the plants will result in lower light intensity, which can lead to slower growth and reduced yields. However, placing the lights too close to the plants can also cause problems like burnt leaves or stunted growth.
The distance between the fluorescent grow lights and the plants will depend on the wattage and type of fluorescent bulb being used, as well as the specific needs of the cannabis plants. Here is a general guide for the recommended distance between fluorescent grow lights and cannabis plants:
| Wattage | Distance from Plants |
|---|---|
| 24W – 40W | 1-2 feet |
| 40W – 60W | 2-4 feet |
| 60W – 80W | 4-6 feet |
It’s important to note that the distance between the lights and the plants should be adjusted as the plants grow. As the plants get taller, the lights should be moved further away to avoid burning the tops of the plants.
The angle of the lights can also affect their effectiveness. Placing the lights at a 45-degree angle from the plants can help to distribute the light evenly and avoid hotspots.
While fluorescent grow lights may require the lights to be placed close to the plants, with proper positioning and maintenance, they can still be a cost-effective and efficient option for growing cannabis plants.
Less Effective for Larger Plants
One of the downsides of using fluorescent grow lights for cannabis cultivation is that they are less effective when it comes to growing larger plants. While fluorescents can work well for small-scale operations and for growing seedlings and clones, they may not provide enough light for larger plants to thrive.
This is due to the fact that fluorescents emit less overall light intensity than other types of grow lights, such as high-pressure sodium (HPS) or light-emitting diode (LED) bulbs. As plants grow larger, they require more light to fuel their growth and develop dense buds. Fluorescents may not be able to provide enough light to yield significant results, especially during the flowering stage.
It’s important to understand the limitations of fluorescent grow lights when it comes to larger plants so that growers can make decisions about their lighting setup that will lead to the best results. If you are planning on growing larger plants, it may be necessary to invest in additional lighting equipment to supplement the light received from the fluorescent grow lights. This may include adding HPS or LED bulbs, or increasing the number and wattage of the fluorescent bulbs used in the grow space.
It’s also important to remember that proper plant training techniques can help maximize the yield potential of cannabis plants grown with fluorescent grow lights. This includes techniques such as topping, low stress training, and using a screen of green (SCROG) setup to promote even distribution of light across the entire plant canopy.
So, while fluorescent grow lights may not be as effective for larger plants as other types of grow lights on their own, with proper planning and technique, growers can still achieve great results using fluorescents as part of their overall lighting setup.
May Require Additional Equipment
Using fluorescent grow lights for cannabis cultivation may require additional equipment to ensure maximum effectiveness. Here are some of the equipment you may want to consider:
- Ballasts: Fluorescent bulbs require a ballast to regulate the amount of electricity that flows through the bulb. These ballasts can often be purchased separately or may come as part of a lighting kit.
- Reflectors: To maximize the amount of light that reaches your plants, reflectors can be used to direct the light toward the plants. These can be purchased separately or come as part of a lighting kit.
- Timers: To ensure that your plants receive the right amount of light and darkness, a timer may be necessary to automate the light cycle.
- Supplemental lighting: While fluorescent lights can provide adequate light for most stages of plant growth, additional lighting may be necessary for the flowering stage or for larger plants. Using LED or HID lights in combination with fluorescent lights can provide the necessary spectrum and intensity of light for optimal growth.
It’s important to consider the cost and benefits of any additional equipment before making a purchase. Proper research and planning can prevent unnecessary expenses and ensure that your grow operation is successful.

To determine the size of your grow space, measure the width, length, and height of the area where you will be growing your plants. Once you have these measurements, you can calculate the total square footage of your grow space. This will give you an idea of how many fluorescent lights you will need to adequately cover the area.
It is recommended to use at least 20-40 watts of fluorescent light per square foot of grow space. For example, a 4×4 ft grow space would require at least 320 watts of fluorescent light (16 sq ft x 20 watts per sq ft). However, if you plan on growing larger plants or want to maximize your yield, you may need more than the minimum recommended wattage.
Additionally, the size of your grow space will impact the distance between the fluorescent lights and your plants. Larger grow spaces may require lights to be placed further away, while smaller spaces may allow for lights to be placed closer. This can affect the intensity of the light that reaches your plants and should be considered when selecting fluorescent fixtures.
Overall, considering the size of your grow space is crucial when using fluorescent grow lights for cannabis. It will help you determine the number of lights you need, the size and wattage of the fixtures, and the proper distance between the lights and your plants.
Place the Lights at the Proper Distance and Angle
When using fluorescent grow lights for cannabis, it is important to place the lights at the proper distance and angle in order to maximize their effectiveness. The distance and angle will vary depending on the type of fluorescent grow light being used and the stage of growth of the plants.
Fluorescent Tube Lights: If using fluorescent tube lights, they should be placed no more than 4-6 inches above the canopy of the plants. The angle of the lights should be parallel to the ground, so that the light is spread evenly across the top of the plants.
Compact Fluorescent Lights: When using compact fluorescent lights, they should be placed no more than 2-4 inches above the canopy of the plants. The angle of the lights should be tilted slightly downwards, so that the light is focused more on the center of the plants.
High-Intensity Discharge Lights: For high-intensity discharge lights, such as metal halide or high-pressure sodium lights, they should be placed at least 12-18 inches above the canopy of the plants. The angle of the lights should be tilted downwards at about a 45-degree angle, so that the light is able to penetrate the plants more deeply.
It is important to keep in mind that the distance and angle of the lights will need to be adjusted as the plants grow and change. As the plants grow taller, the lights will need to be raised to maintain the proper distance. Additionally, the use of reflective material around the grow area can help to maximize the effectiveness of the lights by reducing the amount of light that is absorbed by the surrounding area.
Proper placement of fluorescent grow lights is just one of many factors that can affect the success of your cannabis growing operation. By taking the time to carefully plan and execute your lighting strategy, you can help to ensure the health and productivity of your plants.

- Position the reflector: It’s important to position the reflector correctly to ensure that it reflects as much light as possible onto your plants. The reflector should be placed directly above the plants, with the shiny side facing down towards the plants.
- Create a reflective environment: To further maximize light coverage, you can also create a reflective environment around your plants. This can be done by lining the walls of your grow space with a reflective material, such as Mylar or white paint.
- Adjust the height and angle: Experiment with adjusting the height and angle of your reflector to find the optimal position for maximum light coverage. It’s important to keep the reflector close enough to the plants so that the light doesn’t disperse too much, but not so close that it causes heat stress.
- Use multiple reflectors: If you have a larger grow space, consider using multiple reflectors to ensure that all parts of your plants receive adequate light. Be sure to position the reflectors in a way that minimizes shading from neighboring plants.
- Regularly clean and maintain: Reflectors can become dirty over time, which can reduce their reflectivity. Regularly clean and maintain your reflectors to ensure that they are functioning at their best.
By using reflectors effectively, you can ensure that your plants receive optimal light coverage, resulting in healthier and more productive cannabis plants.
Rotate Your Plants Regularly
Regularly rotating your plants is another important tip when using fluorescent grow lights for cannabis. This is because fluorescent lights provide light from a specific angle, so if your plants are stationary, only certain parts will receive the necessary light for healthy growth. By rotating your plants, you can ensure that all sides of each plant are illuminated evenly, which can lead to better results.
Here are some tips for rotating your plants:
- Rotate them daily or weekly, depending on how quickly they grow.
- Make sure to rotate them in a consistent direction to avoid confusion and ensure all sides get equal light exposure.
