What kind of lighting should I choose for my plants?

In order for photosynthesis, necessary for every plant, to take place properly, exposure to light is a crucial factor.

Light for healthy plants. Discover our tips to make them flourish in your home.

Why should you light your plants in winter?

Regardless of the season, green plants need light – ultraviolet (UV) radiation – one of the basic elements of photosynthesis, essential for their life and growth. For the record, through this process they synthesize organic matter using light energy, absorbing carbon dioxide from the air and releasing oxygen.

In winter, when the sun sets earlier and the days are shorter and less bright, it is sometimes necessary to lend a helping hand to reach the daily quota of light hours. Without sufficient light exposure, plant growth will initially slow and then stop. As a result, it will lose its intense green color, tend to turn pale yellow, and eventually die.

What lighting to choose for indoor plants?

Unlike their counterparts planted outdoors, which benefit from direct sunlight, houseplants are forced to acclimatize to the environment in which they are installed.

It is therefore advisable to place them near a source of natural light, i.e. a window, opening, skylight. For even lighting, be sure to rotate the plant and its container regularly to avoid damaging the background leaves.

In winter, for more light, you can remove the curtains from the window, if the opposite is not too close. However, if your home faces south, west, or southwest during the summer, be sure to move the plant slightly away from direct light so it doesn’t burn.

If the walls behind the plant are painted white or light beige, they will have a light reflection effect that is not negligible. On the other hand, if the plant is in a windowless room, artificial light will be recommended to illuminate it. Artificial light can be used to supplement natural light in certain cases, such as in winter.

Fluorescent or LED bulbs are also effective for additional lighting.

Fluorescent lights

These are gardening lamps, available at garden centers. They should be installed 25-30 cm above the plants. They are often sold with a reflector and a switch.

Depending on the needs of the plant and its stage of development, you decide on a very specific color. For example, blue lights are suitable for the growing season, while red lights are used during flowering. Depending on the size of the plant, you choose one or more tubes.

These fluorescent lamps have the advantage that they do not heat up much and are ideal for small plants.

– LEDs

Low energy consumption, LED bulbs also emit little heat and have a longer lifespan. They offer a wide spectrum of colors: only blue or red, mixed…

The lamps are placed approximately 20 cm above the plant.

How to properly light the greenhouse?

If you want to build a greenhouse, keep in mind that the best place on the property to install it is the one that is the sunniest.

If it is an already built greenhouse, there are several solutions to ensure more light inside. There are several categories of artificial lights, starting with LED bulbs, which are known for their low electricity consumption but have some efficiency. Fluorescent tubes, like long neons, are also an option to consider.

High pressure sodium lamps are recommended if your greenhouse contains plants that will produce flowers and/or fruit.

However, if you install a large number of lights, it is recommended to check the condition of the plants and check that the brightness is not too high and does not cause the opposite effect by damaging them.
