Indoor Plants Lighting Guide

Sunlight is an essential factor that greatly impacts the overall health of any indoor plant. However, one might wonder, “How Much Light Do Indoor Plants Need?” Plants need an adequate amount of light to carry out the process of photosynthesis. It is critical to determine the proper amount of light to keep your plant happy, healthy, and alive. Because your plants can die if they do not receive enough light. This article will go through the light requirements for plants in detail.

Why do plants need light?

To grasp a plant’s light needs, it is necessary first to comprehend “What is the role of light in a plant’s life?”

To begin, understand that plants rely on light energy to produce required nutrients. In the presence of light, they perform photosynthesis, producing food in the form of carbohydrates by utilizing water and oxygen. They then use this energy to grow, blossom, generate seeds, and carry out their regular functions.

The proper sort of indoor plant light is more than just providing a plant with the light it needs. Three illumination elements influence plant growth:

The amount of light: The number of hours of daylight your plants get.

Light intensity: Light intensities ranging from bright sun to complete shadow and

Spectrum: Warm and cool hues in the spectrum.

Types of natural sunlight for Houseplants

Indoor plants do need light for their growth. Some plants enjoy the light of the full sun, while others grow better in the shade. To determine the right sunlight level for houseplants, there are four main types of interior plant lighting for better understanding.

Full sun

Full sun means the plant will receive direct sunlight for at least six hours daily. Some plants, like desert plants, actually prefer full sun and will do best in a south-facing window. Some plants like basking in full sun, but some plants will have damage if they are in full sun. Most houseplants don’t like the full sun.

Partial sun or partial shade

These areas receive less intense sunlight than full sun but more than low light or full shade. Plants that require partial sun or partial shade should be placed in an area where they will receive indirect sunlight for at least four hours per day.

A west or east-facing window is a good spot for plants that need partial sun. The sun will be brightest in the morning and evening, so your plant will get the light it needs without being in direct sunlight all day long. Many plants thrive in partial light and shade near a window, particularly flowering species.

Low light or full shade

These areas receive little to no direct sunlight. Most plants don’t like full shade, but some species grow well in this type of environment. North-facing windows are typically the best place to put full-shade plants. Some of the best flowering plants for full shade include impatiens, begonias, and ferns.

Bright indirect sunlight

This type of sunlight is found in areas that receive direct sunlight for part of the day but not all day long. Some species of plants prefer indirect light or filtered light, such as those that grow under tree canopies. Some examples of plants that grow well in bright indirect sunlight include Spider plants, Peace lilies, Dracaenas, Philodendrons, and Ficus trees.

South-facing windows typically get the most indirect sunlight throughout the day, about a few feet away from the window. East and west-facing windows are also suitable, but not as much as south-facing windows. 

How to Find the Perfect Spot for Your Plan

To determine how much light do indoor plants need, you need to find the perfect spot to get the required quantity of sunshine. Numerous packages or nurserymen provide us prescriptions for their placement, but it still confuses many of us. The next section should provide you with some ideas on where to put indoor plants.

How much light do indoor plants need?, indoor plants, light requirement, sunlight

1. Full sun (direct sun) locations

  • If your plant needs full sun, choose a south-facing window or a room with plenty of light.
  • Be careful not to place your plant in an area where it will be in direct sun for too long, as this can damage the leaves.
  • Once you’ve found the perfect spot for your plant, enjoy watching it grow!

2. Partially shaded locations

  • Place plants a few feet away from east or west-facing windows to ensure they get enough light.
  • Corners of rooms or under the staircase are often the best place for plants.
  • Near windows shaded by trees are another good spot for plants because they will still get indirect light.

3. Low-light locations

  • The best place for plants is in a north-facing window.
  • The other option for low-light plants could be an east-facing window where the morning sun shines.
  • Let your plant rest 3-5 feet away from a window.

4. Bright indirect sun location

  • When placing plants in your home, look for a spot that gets bright indirect sun.
  • The best good option is 3-5 feet away from a south or south-west facing window.
  • Another option is 4-5 feet away from an east- or west-facing window.
  • Make sure the sun shines into the room for several hours each day.

How much light do indoor plants need?

When it comes to giving your plants the right amount of light, there are a few different things to consider. The first is the type of plant you have. Some plants thrive in low-light conditions, while others need a bit more light to flourish. If you’re unsure how much light your plant needs, a good rule of thumb is to start with a low-light plant and move up to a medium-light or high-light plant if it seems like it is struggling.

1. Low-light plants

 Low-light plants can survive in relatively dim conditions, making them ideal for rooms with little natural light or for those who don’t have a green thumb. Some examples of low-light plants include peace lilies, ferns, and philodendrons. So, they’re a good option for those who don’t have a lot of bright light in their home.

2. Medium-light plants 

Such plants need a bit more light than low-light plants, but they can still tolerate some shade. If you’re unsure whether a plant falls into this category, give it a bit more light rather than less. Some examples of medium-light plants include impatiens, begonias, and spider plants. These plants will do best if they’re placed near a window where they can get some direct sunlight each day.

3. High-light plants 

High-light plants need bright light to thrive and often won’t survive in anything less than full sun. If you’re thinking of growing a high-light plant, make sure you have a spot in your home that gets plenty of direct sunlight. Some examples of high-light plants include cacti, succulents, and citrus trees.

Is the plant getting enough light?

Like all other life forms, plants also require times of darkness during the day to rest and grow. But how much light do indoor plants need? Is the light that they are getting enough for their growth or not? Plants that have been exposed to too much or too little light will exhibit symptoms such as:

1. Symptoms plant is getting too much light

If your plant is getting too much light, you may notice some of the following symptoms.

  • The leaves of the plant may turn yellow or brown.
  • The leaves of the plant may begin to become dry and crispy and curl up.
  • The plant may become stunted in growth.
  • The flowers of the plant may begin to fade.
  • The plant may become leggy, with long stems and fewer leaves.

If you notice any of these symptoms, try moving your plant to a location with less light or try adding a sheer curtain to filter the light. You may also need to adjust your watering schedule, as plants in sunny locations will require more water than those in shadier spots.

2. Symptoms plant is getting too less light

  • If your plant is not getting enough light, you may notice some of the following symptoms:-
  • The leaves are smaller than normal, and maybe a lighter green color.-The plant is growing more slowly than usual.-
  • The stem may be thin and spindly. If you think your plant is not getting enough light, you can try moving it to a brighter location. If moving the plant is not an option, you can use a grow light.

If you think your plant is not getting enough light, you should try to move it to a brighter spot. You can also try using grow lights.

Growing House Plants with Artificial Light

If you see signs of less light than the plant requires, you may place it in the care of artificial grow lights to observe better results. If you are growing home plants with artificial light, one of the things you need to be aware of is that not all lights are created equal. There are several varieties of grow lights; each comes with its functionalities.

Fluorescent lights 

Fluorescent lights are often used for seedlings and young plants because they emit a lot of light without producing a lot of heat. However, they don’t provide the full spectrum of light that plants need, so they’re not ideal for long-term growth.

LED grow lights

LED grow lights are becoming increasingly popular because they are very efficient and long-lasting. They emit a full spectrum of light, which is ideal for plant growth. However, they can be quite expensive.

High-pressure sodium grows lights.

High-pressure sodium (HPS) grow lights are often used for flowering and fruiting plants because they produce a lot of red and orange light, which is necessary for these stages of plant growth. However, HPS lights also produce a lot of heat, so they’re not suitable for all types of plants. Metal halide (MH) grow lights are similar to HPS lights, but they produce more blue light, which is necessary for vegetative growth. 

MH lights

MH lights also produce a lot of heat, so they’re not suitable for all types of plants. When choosing to grow lights for your houseplants, it’s important to consider what type of plants you’re growing and what.
