Guide To Gardening Grow Lights Indoor

What is the ideal greenhouse gardening grow lights indoor? Check out this knowledge about best, well-researched, and proven options.

In the growing world of plants, they need light to produce food, and this is achieved by photosynthesis. Green plants absorb light of a specific wavelength and convert water, CO 2, and minerals into glucose.

Without this process, plants can’t grow, so they need enough light.

Of course, plants in the outside world can receive enough light through the gift of nature, while those who want to grow green plants indoors to decorate their houses usually suffer from poor climate or insufficient lighting at home.

When plants are grown indoors, they may not be able to absorb natural sunlight like other plants. This means that they need an alternative light source similar to sunlight to keep healthy growth.

This is the place where led light plants to save these indoor plants.

Gardening Grow Lights Indoor Overview

The photoperiod of plants varies with their types and cultivation stages. LED light plants can provide a variety of spectra, and their luminous power and color temperature are controllable, which is ideal for planting different plants and adapting to different plant growth periods.

Moreover, besides being used for indoor plants that need plenty of sunshine, plant growth lamps can also be used for gardening, indoor gardening, plant propagation, and food production, including indoor hydroponics and aquatic plants.

Knowing the right greenhouse light for plants for your plants is a key step in cultivating healthy indoor plants. To help you solve this problem, here are some common lighting types that you should know about:

Incandescent Lamp

This type of lighting is still one of the cheapest lighting options and is most common in our homes.

However, when used in a greenhouse, they should keep a safe distance from plants, because they will emit a lot of heat, which may damage plants. They are ideal for some plants and are known to last about 1,000 hours.

Fluorescent Bulb

On the other hand, fluorescent bulbs emit blue light, which can promote the growth of dense plants. Unlike incandescent lamps, they generate less heat and save more energy. They are the favorite choice of greenhouse gardeners, especially during sowing.

High-intensity Discharge Lamp (HID lamp)

These types of greenhouse lights are very suitable for large greenhouses. These devices also need to be installed at a safe distance, because they will give off quite a lot of heat.

I found that there are two types of HID bulbs, metal halide (ideal for flowering and germination) and high-pressure sodium bulb (ideal for stimulating plant growth).

LED (light emitting diode) Lamp

This is the latest greenhouse lamp technology we have. LED is more energy-saving, better in performance, and longer in service life than other lamps. LED lights are available in blue or red to produce balanced heating.

With this knowledge, it is easy to choose the right greenhouse light for plants. To make it easier, I have prepared some tips on using plant growth lights.

Should the gardening grow lights indoor be on for 24 hours?

When using the LED light plants, a friend may ask, if I use the plant growth lamp all day, will the indoor plants grow faster and stronger? Absolutely not!

It is not feasible to keep the light on 24/7 because the dark environment is also very important for plant growth. Just as we need to rest at night to rejuvenate our brains and organs, these plants also need to “rest” in the dark to transfer nutrients to their various parts while keeping them from overgrowth.

Plants need a light-dark cycle environment to develop normally, and the amount of light they need varies from species to species. Considering this situation, we just need to find out the proper amount of light needed by our indoor plants every day.

We can check the seed packaging or plant labels, or ask about the specific needs of hydroponic plants for sunlight when they grow and bloom in the nursery.

Where should the gardening grow lights indoor be placed?

Careful placement of growth lamps is also important for them to better simulate the ideal sunshine conditions. Undoubtedly, it is a relatively good position to hang or place the lamps above the plant beds or pots, so that all sides and leaves of plants will be exposed to artificial light when the plant lamps imitate the natural sunlight overhead.

However, it should be noted that we should adjust the position of the growth lamp according to the plant to be planted and the type of the obtained growth lamp to keep a proper distance.

Take fluorescent lamps and LED light plants as examples. They dissipate less heat, so it is generally recommended to hang them at a height of 50-100cm from the plant canopy.

Things to consider when purchasing gardening grow lights indoor


It is very important to determine the appropriate size of a plant growth lamp because it can ensure that the light covers all the plants we plant.

Therefore, when we determine the size of the required plant lights, we should also consider the number of plants to be covered. Remember to leave enough space for plant growth lamps to prevent them from touching other objects in the room, which will affect heat dissipation and cause potential safety hazards.


From light bulbs to high-power plant lamps hanging from the ceiling, there are various types of plant growth lamps on the market at present.

Therefore, if you want to choose a suitable plant lamp, you need to consider the plant type, the existing natural light irradiation, and the plant placement (planting method) in advance.


Because plants need PAR (Photosynthetic Active Radiation) light, you should choose a plant growth lamp with an appropriate wavelength. PAR is between 400 and 700nm.

Electrical Efficiency

Before buying, you should always determine the efficiency of the product. This will ensure that you get maximum results without spending your arms and legs. Looking for high efficiency and low energy consumption plant growth lamp.


Plants need a certain degree of heating, and lower or higher this temperature may be harmful to plants. This means that you should always choose a growth lamp that provides ideal heat dissipation. Some lamps generate too much heat, while others generate too little heat.

Easy to use

Of course, no one wants to face complicated installation or operation after purchasing a plant lamp. Therefore, it is also important to get an easy-to-use plant lamp.

Therefore, it is also an important consideration to choose a plant growth lamp that is easy to install, disassemble and control when purchasing. If you plan to move the plant lamp from one place to another, then it is recommended to choose a lighter portable product.

Of course, if there is a remote control function, it will greatly save us the time of planting with plant lights, and also help us better control the plant growth process.


Indoor gardening is a good way to enjoy life, which allows us to feel the charm of nature at close range without leaving home.

Accepting this guide to gardening grow lights indoor will help you gain more gardening knowledge.

Knowing more about the types and usage of gardening tools will help you get the best planting lights so that your plants can grow better.
