Can I Use Fluorescent Lights to Flower my Plants?

Exposure to of light encourages budding of cannabis plants. It increases THC content making it more potent and desirable for those avid stoners. However, exposure to sun’s natural light poses a lot of limitations including weather and security considerations. That is why some of thecannabis growers prefer to cultivate on indoor spaces controlling the amount of light that goes in through the plants and to assure also safety knowing that there are a lot of people who will judge you on. However, grow lights are expensive and not readily accessible to some places. It is quite difficult for some who wants to cultivate indoors availing such specialized lights. To address this, most people use some alternatives such as incandescent and fluorescent bulbs to cater the need of light upon cannabis plants. But the question, is fluorescent lights doable for growing cannabis plants? Let’s find out upon reading this article whether such thing could be done.

What are Fluorescent Lamps?

Fluorescent tubes are low-pressure mercury vapor with inert gas most typically argon containing tubes that are coated with phosphor powder and which then utilizes fluorescence to generate visible light. It contains a set of electrodes at both ends connected for which electric current flows upon.

As you turned on the light, the electric current passes through the wirings under the tube to the electrodes. This will excite down the electrons on the ends of the tube wherein in response, mercury liquid changes state to gas. This excitation of electrons will result to bumping with mercury atoms. By then, the electrons will be promoted to higher levels and upon returning to normal levels, it will generate photons of light. However, this phenomenon is not readily recognizable by human naked eye and exists as ultraviolet rays. That is why phosphor powder is coated around to convert this form of wavelength to visible light.

These type of lamps are most often used in household and commercial units as a medium to light their spaces. It has been proven to be more efficient than the traditional incandescent bulbs for which overheats easily not containing a ballast for current regulation.

What is the basis for using it as lights for cannabis plants?

As you have noticed, the light emitted by fluorescent bulbs are mostly warm and hot. Likewise, this is most closely associated with wavelengths between blue and red for which could be desirable upon growing especially with the budding phase of cannabis plants.

If possible, this could be an efficient lighting material since its cheap and consumes low power as compared to popular grow lights like High-Intensity Discharge Lamps (HID).

Using Fluorescent Bulbs on Lighting out Cannabis Plants

As you’ve known, growing cannabis is a bit complicated especially if you are planning to do it indoors. That is why you really need to invest money, time, effort, and energy in order to grow your marijuana healthy. It is not an easy job and needs to be planned out including the lights that need to be involved.

Cannabis is a little bit sensitive plant. Likewise, you really need to use lights that are high powered and heats much as it can, resembling the quality of sun’s powerful light. By this fact, fluorescent bulbs do not fit the said description. Yes, the quality of light and its wavelength is doable but plants needed heat to grow. Unless you’ll put your cannabis plants very near to your fluorescent lamps which could be possible for growth.

Also, the area covered by the light of fluorescent lamps are not conducive enough. It is approximated that it could cover out distances only between ranges of one to two feet. Beyond such heights, the fluorescent lights are nonsense.

However, if you want to grow out one to four cannabis plants, fluorescent lamps could be applicable as its source of light. You just need to choose out cannabis strains of short stature since you’ll go to put the fluorescent tubes near to the plant.

But then, you could use fluorescent lamps as a supplemental light to shadowy and dark areas of the room. Let High Discharge Intensity (HID) or LED (Light Emitting Diode) Lamps be your primary light source and fluorescent lamps to brighten out the remaining areas to save energy and money.

Types of Fluorescent Grow Lights

As commonly, there are two types of fluorescent grow lights. These tubes relatively comein different forms and sizes. Otherwise, these are effective for low key garden occurrences and comes with cheap and less energy utilization. The following are two types of fluorescent grow lights. This includes the following;

  1. CFL Grow Lights

These are energy efficient bulbs that are normally twisted shaped being sold in commercial and hardware stores. These bulbs light out narrow spaces for cannabis plants. That is why lighting should be very near within it.


  1. T5 Grow Lights

These resemble like normal fluorescent tubes but extends through a panel. Unlike CFL Grow Lights, you could extend it out few inches towards the cannabis plants for efficiency. But still, inefficient as compared to High-Intensity Discharge (HID) Lamps and Light Emitting Diode (LED) Lamps.


Screen of Green Technique (SCROG)

When you are using a fluorescent grow lights, it is needed for your plants to get near the light. However, it is known that the quality of light isn’t still enough upon heavyexposed to it. That is why this technique is employed to maximize out the light that shines to every small part of the cannabis plant. Because of this technique, fluorescent bulbs could be utilized in order to get cannabis bud and flower more. However, it should be remembered that this method is highly applicable only to thesmall cultivation of cannabis and is unideal for a wide area of growing cannabis.

This method works through employing a specialize fine screen over the canopy of the plant as needed. This is most helpful to Sativa strains of cannabis wherein plants grow tall for which does not fit for indoor cultivation. Likewise, any marijuana strains are still applicable with this method.

Development on Fluorescent Lamps

There are a lot of innovations that have been done to fluorescent lamps. Nevertheless, a stronger, brighter, and warmer lights are now being offered in the market to satisfy any customer’s desires. New classifications of fluorescent lamps have emerged rather than the typical one that we use today. Some of these lamps include; a. color-balanced tubes, b. cool white fluorescent tubes, and c. high wattage fluorescent lights.
