A Comprehensive Guide to Lighting For Houseplants

Why is Sunlight Important for Plants?

• Under almost all circumstances, plants are unable to survive in the absence of sunlight. Through a process known as photosynthesis, they absorb sunlight and work to transform it into energy. Chloroplast cells are the sites where this process takes place. The fact that the chloroplast levels in each individual plant are varied is one of the things that makes plants so fascinating and distinctive. In plants, the amount of light that they are able to take in is proportional to the amount of chloroplasts that they contain.
• But as we are all aware, nature possesses a limitless supply of resources. Depending on the amount of light that is available, plants are able to alter the quantity of chloroplasts that they make. When plants are subjected to the process of hardening and are provided with doses of sunshine in more frequent bursts throughout the course of time, it is possible to observe this phenomenon. You can make use of the adaptability of your houseplant to assist it in adjusting to the environment in which it is kept.

Measuring Light

• Lumens and lux are two units that can be used to quantify the illuminance or brightness of light that the human eye is able to perceive. The measurement of illumination that is achieved through the utilisation of visible light by a source per unit of time is referred to as lumens. Lux is an equivalent measurement that employs area as the unit of measurement. In terms of lumens per square metre (3.2 feet), one lux is equivalent to one lumen.
• In terms of a more practical perspective, a light bulb that is 100W and stands will give you approximately 1600 lumens. In general, the suggested level of lux for a room would be somewhere around 150 lux. However, the lux level would vary depending on the amount of total space that the light will illuminate.
• This is not sufficient for the cultivation of plants. The majority of indoor plants require between 1000 and 2000 lux, which is roughly equivalent to “bright, indirect sunlight.” Positioning will be of the utmost importance in order to guarantee that the plants receive sufficient light.

Use Technology

• A light metre is one of the most straightforward methods for determining whether or not your plants are receiving an adequate amount of light. They are frequently utilised by photographers as a means of determining the amount of light that will be absorbed by a lens, and they are known to be quite precise.
• The problem is that there is no list of plants that can claim with absolute certainty that a watermelon peperomia requires a light intensity of one thousand lux in order to function at its highest level. Furthermore, because of its ability to alter its chloroplasts, which was mentioned before, the production of a list is not a practical utilisation of the time that a researcher has available.
• There are, however, a number of applications that you can download (some of which are free) that will provide you with an overall indicator of the amount of light that is present in your home. The majority of these apps also include a convenient warning that indicates there is not enough light. Use these, even if it’s only for fun, and you won’t regret it.

Understanding Light Indoors

• It is not the same thing to cultivate plants outside as it is to cultivate their roots within. It may appear to be self-evident, but it is essential to be aware that windows have the ability to either magnify or dilute light, so influencing the intensity of the light. You can significantly lessen the intensity of the light by moving plants to a location that is only a few feet away from a light source, such as a window.
• Around 10,000 to 25,000 lux is the range of light that can be found outside during daylight hours, provided that the sun is not up. This is something that is really difficult to accomplish indoors unless you have made a significant investment in artificial grow lights.
• The majority of the indoor plants that we purchase have been grown in a greenhouse with light that has been artificially regulated by the grower to ensure that the plants are able to reach their full potential. It is possible that it will not receive exactly what the grower gave it after it is brought into your home. A magnifying effect caused by the glass in a window can cause the leaves of plants to become scorched, which is another way in which sunlight that enters a window can be extremely harmful to plants.

Window Aspect

• When the sun goes in and out of orbit throughout the day, the direction in which a window in your home faces—whether it is to the north, south, west, or east—has a significant impact on the amount of light that enters your home. The following is a list that is comprised of windows that are located in the Northern Hemisphere:

General Lighting Categories for Houseplants

• In the care instructions for a plant that you purchase, you will frequently find an indication of the lighting requirements that the plant has. These requirements typically tend to fall into the following categories:

Direct Light

• Plants such as trees, cacti, succulents, and kitchen herbs are examples of those that thrive best when exposed to direct sunshine through a window. You can cultivate these plants either outside in the sun or indoors as houseplants at your leisure. In most cases, they would like to have at least six hours of direct sunlight each day, in addition to having plenty of light elsewhere during the day.

Bright Indirect Light

• When it comes to houseplants, this is the phrase that is used the most. There are many different kinds of plants that fall under this category, such as climbers, miniature trees, and tropical plants with both large and small leaves. They arise from the canopy of tropical rainforests, where they were first discovered. Even if they are accustomed to dappled shade, they would rather be not exposed to direct sunshine.

How to Tell if Your Plant is Getting Enough Light

• A sufficient amount of light is being provided to plants that are both healthy and growing nicely. In the event that your plant is not receiving sufficient light, it may frequently stretch out and become lanky, thereby leaning towards the light. As a result of those receiving an excessive amount of light, you might notice that the leaves have burn scars, which indicate that they have been burnt by the sun, or that the leaves begin to yellow. Trying the plant in a different place with more suitable lighting is all that is required to bring about the desired results.

Top Up with Artificial Light

• In the event that you are serious about your houseplants, it is possible that you will require artificial light in order to provide your plants with the amount of light that they require. There is a wide variety of lighting that is designed exclusively for plants, whether it be for houseplants, herbs for the kitchen, or seeds that are planted indoors when it is freezing outdoors. The typical illumination in a house is not going to be sufficient for the task at hand. Before adding additional lighting to your room, there are a few factors you should take into consideration.
• Choose lights that achieve the closest possible resemblance to sunlight that the makers can create. These will be referred to as “full spectrum” or “broad spectrum” LED or fluorescent lights, and they will be sold specifically for plants and plants that are growing.
• The blue and red light components of full spectrum lamps are in equal proportion. Not only does blue light encourage the growth of green leafy foliage, but it also helps to preserve stems at a shorter length. Red light is warm and encourages the growth of vegetative tissue, which results in bigger flowers and taller stems. The optimum results for your plants will be achieved by utilising a combination of these colours in a balanced manner.
• Kelvin, the unit that is being used to measure thermodynamic temperature, is also being utilised in the lighting industry to measure the colour temperature of a light bulb. This is being done without getting too mired down in measurements. The Kevin rating for the light bulbs that are closer to sunshine and are required for plants should be between 5000 and 6500,000.

Final Thoughts

• The process of bringing in sufficient light into a home in order to provide houseplants with the opportunity to flourish can be difficult, but it is more of an experiment that involves both trial and error. There is no harm in rearranging plants in order to provide them with the nutrients they require.
• I have a vacation flat that is full with houseplants, and when they appear to be in a state of distress, I bring them into my office, where there is a lot of light, and I give them some much-needed attention and care before reintroducing them to the apartments. Due to the fact that some plants are able to thrive in any environment, while others have a difficult time thriving, there is a great deal that can be taught simply by studying our lovely flora.
