Many people love gardening. But gardening doesn’t mean that you have to plant trees, shrubs, and herbs in an open area only. You can create an indoor garden by installing lamps for the required temperature and light. The following article goes through different indoor plant growing lights and the best lamps for the indoor gardeners. Let’s check out the various things required for building an indoor garden. 

Types of Indoor Lights for Plants

There are different types of indoor lights for growing plants in an indoor garden.

Fluorescent Lights 

These lights are also known as T12, which help in growing various house plants and seeds. It helps by providing natural light like the sun. It fulfills the basic requirements of plants and helps them to grow like other natural plants. The intensity of the light is quite weak, but it is necessary to place your plants at a distance of a few inches to get more effective results. 

The diameter of T12s is comparatively narrower than other lightbulbs. You can search for full-spectrum grow bulbs that perfectly fit into your available socket and give the right amount of light to your flowering plants.

Compact Fluorescent Bulbs (CFLs)

These bulbs work best in small spaces, or if you have a fewer number of plants in a compact place. Compact Fluorescent Lights do not use the T5 system and are not much more expensive than incandescent lights. 

These bulbs are available in different wattages. Make sure that you choose one that is perfect for your plants and space. If you have carnivorous plants as well as Phalaenopsis orchids, those plants will grow well in these lights. 

LED Grow Lights

The LED indoor plant grow lights are comparatively more expensive than fluorescent or compact fluorescent bulbs. But, the consumption of electricity is less and comes with a long lifespan. Regular LEDs are not meant for growing plants because plants require different levels of lighting from different LEDs. 

This technology is currently massive in demand among various horticultural suppliers. If we compare LED bulbs with fluorescent bulbs, LEDs are full-spectrum and have a higher intensity. These lights work, even if you have a large number of plants. They do produce some amount of heat. Therefore, it is recommended not to use these lights in a compact space. 

HID Lights

HID bulbs were preferred before LEDs came into existence for growing plants in an ample indoor space. The primary reason to switch from HID to LED is that these lights are quite powerful and expensive. It consumes more electricity and also needs unique light fixtures. The lights also emit a considerable amount of heat. But despite so many drawbacks, HID lighting is beneficial and still used in many places. The light penetrates deeply into the plant foliage and provides enough light for growth. 

If you want to plant lemon bushes or tomatoes on a large scale, then you might prefer these lights. HID is classified into two categories. High-pressure sodium (HPS) light bulbs are low in the spectrum and best for flowering plants. On the other hand, Metal Halide (MH) light bulbs are high in the spectrum and help in vegetative growth. 

Incandescent Lights

These lights are best for growing houseplants that require less light. Plants like vines, dracaenas, or ferns can be grown under these lights. There is no need for high-intensity light for growing plants. There is a 10% light and 90% heat ratio in these lights. 


Halide bulbs are used to grow large plants in larger spaces. It covers a lot of distance in terms of light. There is no need to get a 1000 W bulb if you have halide lights. It is essential to provide dark hours to your trees. Make sure that you keep your plants under light for 12 to 18 hours every day. 

What Things are Required to Install Lamps for Indoor Gardening?

Nowadays, indoor gardening is trending across the globe. It can be an easy job if you know what tools you require and how to install a few things for better plant growth. Your requirements for installing lamps may depend on the size of your garden, types of plants, and type of bulb required as a lighting source. Let us review a few things to figure out what you need. 

Calculate Number of Bulbs Required 

All fruit and vegetable plants need only 30 watts of light per square foot. If you have fruiting plants like tomatoes, you must remember that it can produce high-quality fruits only when you provide at least 40 to 50 watts of light per square foot. You need to determine the wattage because every plant, herb, or shrub requires different lighting. It is easy to calculate the wattage by multiplying the watts’ number with the square foot of the growing area. After that, divide it by the number of watts of a bulb that you are planning to use.

Get a Light Rack

It is necessary to install the bulbs at a certain height from your plants. Get a sturdy light rack with adjustable height. You can change the height of the rack whenever required according to the plant growth. You can also hang the light fixtures with the help of a metal chain. It makes it easy for you to adjust the height of the bulbs by managing the light fixtures. Some LEDs are also installed over the rack to provide constant light to the plants. 

Install Other Necessary Things

It is essential to set the timer of your lights. Indeed, these lights grow plants slowly as compared to the sunlight. Therefore, it requires 12 to 18 hours of direct light. But excess light can damage or burn them. You can set a timer to provide light for limited hours. 

Make sure that the temperature of the indoor garden is exact and perfect for growing saplings. If the temperature goes up by 80 degrees, then you must have a good ventilation system to avoid excess heat. You can use reflectors and other accessories to get amazing results.


The plants must be placed at the appropriate distance without any damage. As we know, there are different types of lights available in the market for growing indoor saplings. Every bulb must be installed at a different distance. 

For example, Fluorescent lights must be 3 to 12 inches away from plants. On the other hand, LEDs must be 12 to 24 inches, and HID light must be 24 to 60 inches. If you keep your lights at some distance, then you can prevent severe damage to your plants.
