How To Choose The Best Light for Growing Plants Indoors (2021 edition)

Lighting for Plants Growing Indoors

Sometimes it can be quite hard to provide for sufficient light to your houseplants because of many reasons, including seasonal changes or simply just a lack of space. Here, a good indoor lighting can come in handy to help retain a healthy plant and its aesthetic looks. With the perfect set of lighting you can grow many types of plants indoors such as simple houseplants and orchids or even some fruit and vegetable plants! These indoor lights that help in plant growth are commonly known as ‘Grow Lights’. They are also ideal for seed-starting or germination and ensure stocky, healthy and green seedlings. Lets us review 5 best light for growing plants indoors.


Choosing the Best Grow Light for Your Home

When using Grow lights for your plants, it is critical to keep some things in mind such as the intensity of the light, color of the light, duration of provision of the light source and what kind of light like incandescent, LED, Fluorescent and others.

Choosing the Best Grow Light for Your Home

This would essentially depend on the brightness of the bulb used in the Grow Light as well as the distance between the plant and the source of light. Since plants vary in their requirements of intensity, this will have to be considered before matching your plants with your Grow Lights. A general thumb rule is most flowering and fruit/veggie plants require high intensity lights whereas foliage plants can be positioned about 36 inches away from the Grow Light.

Right Color of Light

Sunlight encompasses the entire spectrum of white light and thus has all the colors of the rainbow from violet to red. Thus, impliedly indoor plants grow best when placed under lights with bulbs of the whole spectrum. This provides a natural balance of warm as well as cool light imitating the natural spectrum.

Right Duration of Light

Plants respire in the dark and thus it is pertinent that plants get their time of darkness as well. Thus a good Grow Light should typically include a built in timer as well. Plants that fit in the Short-day category of plants would require about 12 hours of contact with light. Those that are classified as long-day plants would require nearly 14 to 18 hours of light per day and those that are day-neutral only need about 8 to 12 hours of light throughout the year!

What Type of Light Should You Be Using

Incandescent lights: They can be used for plants that require low amounts of light. Most of their energy is heat and thus must be kept at an appreciable distance from the plant or you’ll end up cooking your plant.

Fluorescent lights: These long, tube-like bulbs are ideal for those plants that require low to medium amounts of light. The ideal type of fluorescent bulbs to grow most plants indoors would be those of around 6000 to 8000 Kelvin, which would typically appear more bluish in color. Using T8 or T5 bulbs kept at a distance of 2 to 4 inches away from the plant would aid in the growth of seedlings and even starter plants. For grown plants a distance of 1 to 2 feet should suffice.

Compact Fluorescent Lights: They are great for growing indoor plants and are not as expensive as incandescent lights. Here, however, wattage is subject to variation and you will have to ask around to find out what works best for your plant. Usually this kind of light source is best for some types of orchids and carnivorous plants.

LED Bulbs: Like fluorescent bulbs, LEDs also provide full spectrum light and is also easy on the pocket. They also use half the amount of electricity and are better for the environment. The blue light provided by LEDs stimulates healthy growth of the plant and its roots.
