Can Plants Get Too Much Light?

There’s a question many people are asking if there is an issue with excessive lighting to your plant? It’s a tough question to answer, with every plant with different needs however, the majority of plants suffer when they’re exposed to too much sunlight.

There are two ways for plants to be exposed to too much light: excessive duration of light and a very high intensity of light.

We’ll take a closer look at them below and also the most common indicators of light damage , and the most effective light source for your plants to begin with.

Light Intensity

The intensity of light is the reason for the majority of harmful consequences that can result from a plant being exposed to excessive light.

The intense light could cause your plant to be exposed a harmful quantity of energy from light, and also a substantial quantity of heat.

The heat energy has to be removed, which typically involves the plant using the water it has available to cool down.

After a time the plant’s water reserves could diminish to the point that there’s not enough water to support vital processes like growth and photosynthesis.

If the plant’s capacity to release heat is exhausted or the heat output is greater than the plant’s capacity to disperse it, your plant is likely to suffer heat damage.

Additionally, the light intensity may dry out the soil that your plant gets its water. This could trigger the dehydration of your plant.


Excess Light Duration

The majority of plants can be exposed sunlight for long durations of time, and they will develop. However, exposure to sunlight for too long could alter the growth rate of certain plants.

There are many plants that cannot advance to the next stage of growth or flowering with a minimum amount of darkness throughout the day. Some examples of these plants are Poinsettias as well as Christmas Cacti.

Incredibly, other plants also grow more in the evening due to certain metabolic processes that occur during the night.

In general, the development cycles tend to be affected by the length of time that light is available however, the plants themselves are not often damaged.

  • A hint of yellowing could be evident on the tips of the leaves
  • The wilting of the younger leaves

Does LED Light Burn Plants?

All of this is dependent on the amount of heat that is emitted by the LED light as well as the intensity of the light energy that is transferred into the plants.

Be aware of the fact that grow light bulbs with LEDs must be set at a suitable distance away from the plants that you’re trying to cultivate. It’s true that this will differ significantly depending on the brightness of the light you’re using as well as the particular plants you’re cultivating.

It is also essential to select particular grow lights specifically designed for plants instead of using the standard LED bulbs. The light that is emitted by regular LED bulbs is largely ineffective for the growth of plants.

The light that enters windows can be as much as 50 percent less intense than direct sunlight outside, however in the case of many plants that are indoor,, this could still be enough to cause harm.

For instance, ferns thrive when they are in indirect light however they can be affected if placed directly in front of windows.

If you’re growing plants indoors, the most effective remedy to damage caused by light can often be as easy as moving the plant to an area that is more suitable for it.
