Whether you're a seasoned plant parent or just starting out, knowing the light requirements for plants can make all the difference in how your plants grow and overall health.
We'll discuss the different types of light intensity, the types of light your indoor plant needs, and how to determine the perfect spot for your plant to thrive. So, let's shed some light on the subject and help your plants reach their full potential!
What factors should you consider when choosing optimal lighting for your indoor plants?
Generally, indoor or house plants require bright, indirect light for at least 6-8 hours per day.
There are different factors to consider when determining how many hours of light your house plants need. First we must consider the following:
Different types of plants have different light requirements. Some plants, such as African violets, prefer low light levels, while others, such as orchids, need bright light.
Plants have different light requirements during different growth stages. For example, plants in the vegetative stage require more blue light, while those in the flowering stage require more red light.
The intensity of light also plays a role in plant growth. Plants that receive too little light may become leggy and weak, while those that receive too much light may become burnt or stressed. While some plants (like specific varieties of hoyas) will not be harmed by sun stressing, others will become damaged under too much light.
What light source is most popular for indoor settings?
Some plants require bright, direct sunlight, while others thrive in medium light conditions. Identify areas in your home where you receive the most natural brightness of light. Bright light will cast harsh shadows, while indirect light will cast soft ones.
If you are placing a plant in a low-light position, but need more light to meet their needs, you'll want to invest in a grow light. These come in a variety of colors:
Full-spectrum light is the closest light to natural sunlight, providing a balanced mix of blue, red, and green wavelengths. It is suitable for all plants and is essential for plants that require high levels of light, such as vegetables and flowering plants.
Blue light promotes plant growth and is ideal for plants that require short-day photoperiods, such as strawberries, lettuce, and spinach. Blue light is also suitable for seedlings and young plants as it encourages the development of strong roots and sturdy stems.
Red light is essential for flowering and fruiting plants as it stimulates the production of flowers and fruits. It is also beneficial for plants that require long-day photoperiods, such as tomatoes, peppers, and cucumbers.
Green light is not as critical for plant growth as blue and red light, but it is still useful. It helps plants regulate their growth and development and is beneficial for plants that grow in shady areas with limited access to sunlight.
Ultraviolet light is essential for plants that require high levels of light, such as succulents and cacti. It stimulates the production of pigments that protect the plants from harmful UV radiation and helps the plant to thrive in extreme conditions.
Far-red light is necessary for some plants to break dormancy and initiate flowering. It also helps regulate the plant's growth and development.
