Are you concerned about how window film can impact your plants? Even though most plants thrive in environments with tinted window coatings, you might need more information before making any judgments.
Will Window Film Kill My House Plants?
In many circumstances, adding window film to your home shouldn’t hurt indoor plants as long as they are already receiving enough light. The greenery might need a few days to become used to the new lighting, which could initially have an impact on new plant development and flowering. Your plants shouldn’t notice much of a difference if an optically transparent window film, like UV Gard by Madico, Inc., is installed. A transparent window film transmits 80% of visible light, which is sufficient for your indoor plants even while it blocks out 99% of UV rays.
You might observe that plants that ordinarily wither before the end of a sunny day flourish even more once the window film is put in. Window coatings improve the environment for these kinds of plants by blocking some of the intense light and heat that can dry out or scorch delicate blossoms and leaves.
Consider transferring the plant to a room with less sunlight for a few days to observe how it reacts if you’re worried that installing window film will harm your indoor plants. Keep in mind that most plants are sensitive to environmental changes, so make sure you leave the pot in the new location long enough to observe if it recovers. Additionally, the majority of nurseries or regional agricultural organizations can offer guidance on how much light a specific plant needs.
Will Frosted Window Film Affect My Plants?
For homeowners who desire a little more privacy or a more uniform appearance in a space, decorative frosted window film is a great choice. Many people ask if these films block too much light for their indoor plants because they impede vistas. Frosted windows alter the lighting in the space by diffusing and softening the sunlight that enters the space.
Most indoor plants receive enough light from a popular frosted window coating called Frost Matte by Madico, which transmits visible light at a rate of 67 percent. Since diffused light is a novel and unfamiliar environment for your plants, give them some time to acclimate.
What Types of Plants Need More Light Than Others?
Variegated or lighter-leaved plants typically require more light than their darker-leaved counterparts. Because they contain more chlorophyll, darker leaves are better equipped to exploit the available light for photosynthesis.
What Kind of Light Do Plants Need to Grow?
Plants do not require ultraviolet (UV) light to grow, despite popular perception. Red and blue light, which are not in the UV color spectrum, are necessary for plants. Chlorophyll is produced more readily in blue light, which aids plants in developing robust, healthy stems and leaves. Red light supports seed germination, bulb development, and root growth in the early stages of a plant’s life. Additionally, it enables a plant to blossom and bear fruit.
On the other end of the spectrum from UV light, infrared (IR) light is also necessary for plants. Ample far-red wavelength exposure can promote healthy stem growth and blooming. However, an excessive amount of infrared radiation can harm flowers, leaves, and stems. The majority of window films block part of the heat-producing infrared light. With this function, homes can save a ton of electricity. It will also benefit plants that are prone to damage from heat and intense infrared light.
Your plants shouldn’t be deprived of the far-red light they require by glazing that absorbs only a little amount or a moderate amount of IR energy. You can choose a window film that blocks up to 70% of the radiation from the sun without risk.
Does Solar Control Window Film Block Natural Light?
With the exception of blocking damaging UV rays, transparent solar window film still lets natural light into your house. In order to create the ideal balance between natural light and UV protection in your house, there are numerous designs and colors to pick from.
Red and blue light are partially blocked by tinted window coatings, which darken your windows to hide more visible sunlight. A film’s visible light transmittance determines how much light it lets through. A larger percentage suggests it lets in more natural light, whereas a lower percentage shuts out more of the sun’s rays.
The optimal window film for plants typically has a light transmittance of at least 25%. Films that are very reflective or opaque may block more than that, therefore they shouldn’t be put on windows where you want to maintain potted plants. However, the majority of window coatings have a transmittance level exceeding 25% and allow in a lot of natural light. If your plants require a lot of sunlight, think about choosing a film with a light penetration of at least 50%.

Can a plant survive on UV light alone?
The reality about UV light in the grow chamber can be a little hazy at this point. Because UV-C radiation cannot penetrate the ozone layer, plants are not naturally exposed to it in the open air. They don’t require it for growth, and it’s one of the most harmful light spectrums to expose your plants to. Many growers are unaware that UV-C can harm a plant’s DNA.
Having stated that, UV-C lighting wands are frequently marketed as a portable equipment used to sanitize the workspace of bacteria. These wands take inspiration from the UV-C water sterilization technologies used in remote areas. In the end, UV-C exposure causes everything to perish, including your plants. If you do decide to use a UV-C wand in your grow room, be sure to wear protective clothing and avoid prolonged exposure for both you and your plants. UV-C is not produced by your grow lights, and your plants do not require it to grow.
Why is UV light necessary for plants?
Now that you are aware of what a UV wavelength is, let’s discuss how it affects plants. People that utilize grow lights with UVs assert that they are more adaptable, produce higher-quality yields, better colors, and smells and scents. But is that actually true?
Let’s examine how a UV wavelength can impact a plant to determine whether or not it is true.
Faster Photosynthesis
It has been demonstrated that ultraviolet light aids in accelerating photosynthesis and promotes greater plant development.
According to a study that appeared in the peer-reviewed journal Oecologia, UV-A light exposure improved photosynthesis by 12%. Another study indicated that UV-A light increased leaf size, dry weight, and growth potential. This study was also published in Scientia Horticulturae.
Giving your plants a full spectrum of light that includes UV light can undoubtedly help if you want to increase the crops they produce.
Increased Resin Production
The production of resin by plants, which boosts flavonoids and terpenes in your plants, is aided by ultraviolet light. Terpenes give plants their flavor and smell, whereas flavonoids are in charge of some plants’ rich, vivid hues.
Whenever a plant is exposed to a strong UV wavelength, the plant responds by making resin. Resin is a shield that prevents fungi, insects, infections, and other health threats from harming plants or causing them to lose water.
Enhanced flavor and aroma
When resin is secreted, flavonoids and terpenes are released, which results in a yield that is more flavorful and aromatic when it is harvested. Because of this, you may make plants produce more resins and release richer flavors by applying UV to them.
An increase in pest protection
Increased resin means increased defense against pathogens and pests thanks to ultraviolet light. Your plants are on their way to dream harvests when they aren’t being devoured by bugs or struggling to recover from a foreign ailment.
Increased Production of Roots
Roots may receive UV radiation, and even brief exposure aids in boosting root mass. This will be useful when it’s time to move plants into brighter lighting or from indoor to outdoor environments (and vice versa). When planted in a new environment, they won’t have to develop stronger roots, increasing their capacity to flourish.
Bleaching
Your plants will suffer if a UV light is too bright or placed too close to them. Your plants will become bleached as a result of excessive UV exposure.
Overexposure to a UV wavelength makes matters even worse when it comes to bleaching, which happens when a plant’s cells are exposed to too much light and get damaged and discolored. As a result of the leaves’ inability to absorb light, bleaching causes stunted growth and a meager yield.
Terpenes and flavenoids are both severely harmed by excessive UV exposure. Fruits and buds that are bleached by excessive light might lose flavor and aroma even if your leaves are unaffected.
Can plants use UV light in place of sunlight?
Make sure to give your plants a top-notch UV grow lamp for the greatest outcomes.
Just the proper quantity of each form of UV is emitted by the majority of full spectrum LEDs. Additionally, it will replicate natural sunshine, giving plants the impression that they are being grown outside.
Even grow lights made of ceramic (CMH) and some double ended (DE) bulbs generate UV light.
We have a large range of UV Spectrum LED Grow Lights here at Hydrobuilder. Some of our favorites are as follows:
Black Dog LED Grow Lights
For grow lighting, Black Dog LED is the market leader. They were designed with a significant deal of research, and the result is the best plant-growing spectrum ever.
The Phyto-Genesis Spectrum, which contains the ideal quantity of UVA light for plant growth, is utilized throughout the whole PhytoMAX series of LEDs.
They tried with include UVB in the spectrum but found that UVA alone had better results. So they completely omit UVB.
Although they are frequently referred to as the best LED grow lights money can buy, they are out of most growers’ pricing ranges.
California Lightworks LED Grow Lights
They offer a wide variety of LEDs with enhanced UV spectrums to promote growth in addition to all the other advantages outlined above. Here are some excellent choices:
Which kind of grow light is ideal for houseplants?
Although not all grow lights are created equal, they all provide plants with the energy they need to transform light into nourishment. Consider the following categories to gain a better understanding of the variations in grow lights now available on the market.
Light spectrum
Most plants require a variety of colors to survive. Despite the fact that typical grow lights appear clear or white to the unaided eye, they actually emit a variety of colors in varied intensities. This type of light is called “full spectrum.” There are some hues in that spectrum that are particularly beneficial to houseplants.
- Plants need chlorophyll to flourish, and blue light aids in the production of this pigment. Young plants and seedlings benefit by having more favorable conditions for germination and root growth.
Are LED lights beneficial for houseplants?
The least expensive technology is incandescent grow lights, but they are also the least energy-efficient and produce a lot of heat.
Fluorescent lights produce a good spectrum of light for growing and have a minimal heat signature. They often come in the form of reflectors for tube lights or CFLs. Growing under fluorescent lights is more cost-effective than growing under incandescent lights, although it uses less energy.
The most recent technology on the market is offered by LED grow lights. They are incredibly energy-efficient, produce incredibly little heat, and have the perfect light spectrum. The most effective, efficient, and user-friendly way to grow plants at home is with LED lights rather than fluorescent or incandescent lighting since they use less energy, produce less heat, and have colors that are tuned for growth.
A tungsten electrode and an alumina-fused tube form an electric arc to create light in high-intensity discharge (HID) bulbs. These speciality bulbs are frequently employed by industrial growers and have a very high light output level.
A strong light source is produced by metal salts and mercury vapor in metal halide lights. Like HIDs, they make use of a unique fixture and are frequently employed by commercial establishments.
Can plants get enough light from windows?
The majority of houseplant types need indirect light, making indoor cultivation of these plants ideal. Direct light may be tolerated by some varieties of crotons, cacti, and succulents. However, indirect light typically outperforms direct light for household gardening.
Direct sunlight is present when the sun’s rays hit the plant’s leaves straight through the window. Except for windows facing south, most areas in your house get indirect light.
During the hottest portion of the day, place your hand between the window and the plant. Do you notice direct sun exposure on your skin? If so, there is sunlight here.
When the sun’s rays first reflect off of another object before reaching the plant, this is known as indirect light. There won’t be direct exposure to the sun’s rays, but an area of indirect sunlight will be brightly lit.
Are UVA or UVB required for plant growth?
Based on wavelength, UV light for plants is divided into three categories:
- In the range of 320 to 400 nm, ultraviolet A (UVA) photons make up roughly 3% of the photons in natural sunlight that pass through the atmosphere of the Earth. The DNA of plants is not harmed by UVA lights.
- The UVB spectrum, which ranges in wavelength from 290 to 320 nm, accounts for less than 0.15 percent, or one-fifth of one percent, of all natural sunlight. UVB light has enough energy to damage DNA and even start cancer in animals. Fortunately for humans, the ozone layer of the Earth completely absorbs UVB radiation from the sun.
- Since the Earth’s atmosphere almost entirely filters out ultraviolet C (UVC), which ranges in wavelength from 100 to 290 nm, it is not a part of natural sunlight. Because UVC light has sufficient energy, it can be utilized to sterilize objects by killing live cells.
Different plants react differently to UVA and UVB radiation, but studies have generally indicated enhanced production of antioxidants, flavonoids, and other natural sunscreen components in a process known as photomorphogenesis.
UVA light rather than UVB light causes cannabis plants to produce more THC and CBD. The 1987 study “UV-B Radiation Effects on Photosynthesis, Growth and Cannabinoid Production of two Cannabis sativa Chemotypes” by John Lydon, Alan Teramura, and C. Benjamin Coffman raised several questions. The study cultivated cannabis plants, of which some were exposed to UVB light and others to no UV light at all. It discovered that the UVB-exposed plants had higher THC concentrations than the ones that received no UV light at all.
Some have interpreted this to suggest that cannabis plants can only produce more THC when exposed to UVB light, however this study does not support that. First, because just UVB or no UV radiation was used in the study, no conclusions can be drawn regarding how exposure to UVA impacts cannabis plants’ ability to produce THC. Second, because the cellulose acetate filter they used to try to eliminate UVA light from their broad-spectrum UV source was later shown by a different study to allow UVA light to pass through, the study’s setup was flawed and really only tested whether exposing Cannabis plants to both UVB and UVA increased THC production compared to no UV light at all. Therefore, the original study did not determine whether exposure to UVA, UVB, or both boosted THC production over exposure to neither UVA nor UVB radiation.
