Aquarium plants need light to survive, and they need so much light that many people are unsure how long to leave their aquarium lights on each day.
The answer, however, is not as simple as “leave them on for X number of hours.” Different types of plants require different amounts of light, and the amount of light you need also depends on how deep your aquarium is.
Of course, there are always exceptions to the rule. Some plants, such as Anubias and Java ferns, can do well in low-light conditions. Others, such as most stem plants, need light to grow.
In this article, we will discuss how many hours of light do aquarium plants need.
How Many Hours of Light Do Aquarium Plants Need?
Most aquarium plants need between 8 and 12 hours of light per day to thrive. If you have a shallow aquarium (less than 20 inches deep), you may be able to get away with less light. Conversely, you may need more light if you have a very deep aquarium (more than 24 inches).
What Happens With Too Much or Little Light in Aquarium?
The plants may grow too tall and leggy as they stretch towards the light with too much light. This can make the plants less attractive and less efficient in using sunlight to produce energy.
With too little light, the plants may not grow at all or may grow very slowly. They may also become pale and have fewer leaves. Either way, the plants will not be able to photosynthesize as efficiently and may eventually die.
Different Plants Have Different Needs
When it comes to aquarium plants, there are a lot of different varieties out there with additional needs. Some plants need a lot of light, while others can do well in lower light conditions.
It’s important to research the specific plants you want to include in your aquarium and ensure you provide them with the right environment to thrive.
Here is a list of freshwater aquarium plants with different light needs:
|Freshwater Aquarium Plants||Needed Light|
|Java Fern||Low to Medium Light|
|Jungle Val (Vallisneria)||Medium to high Light|
|Java Moss||Low to Hight Light|
|Pygmy Chain Sword||Medium to High Light|
|Amazon Sword Plant||Medium to High Light|
|Rotala willichii||Medium to High Light|
Difference Between LED and Fluorescent Light
LED and fluorescent light are two types of lighting commonly used in aquariums. They both have their pros and cons, so how do you decide which suits your tank?
LED lights are newer on the market and tend to be more expensive than fluorescent lights. However, they also last longer and use less energy, making them more cost-effective in the long run.
LED lights also emit very little heat, so they won’t raise the temperature of your tank water.
Fluorescent lights are less expensive upfront and used in aquariums for many years. They emit more heat than LED lights, so you’ll need to be careful about how close you place them to your tank.
Fluorescent lights also need to be replaced more often than LED lights.
So, which type of light is right for you? It depends on your budget and what you’re looking for in an aquarium lighting system.
If you want a long-lasting, energy-efficient light, LED is the way to go. If you’re on a tight budget, fluorescent lights may be a better option.
Whichever you choose, do your research to ensure that the light you select is appropriate for the plants and fish in your tank.
How To Regulate Aquarium Light?
Aquarium lights come in various shapes and sizes, and it can be tough to regulate how much light your aquarium plants get.
Too much light can cause algae growth, while too little can stunt plant growth. Luckily, you can do a few things to make sure your aquarium plants get the light they need.
First, consider the type of light you are using. LED lights are becoming increasingly popular for aquariums as they use less energy and last longer than other bulbs.
If you are using an LED light, it is important to get one that emits the full spectrum of light, as this will ensure that your plants get the full range of light they need.
Next, you’ll need to decide how long your light will be on. This will depend on the type of plants you have and the time of year. Aquarium plants need around 8-12 hours of light per day.
However, during the winter months, when days are shorter, you may need to increase the amount of time your light is on to ensure that your plants get enough light.
Finally, it is important to regulate the intensity of the light. Too much light can be just as harmful as too little light, so it is important to find a balance.
Using an LED light, you can typically adjust the intensity by using a dimmer switch. If you are using a different type of light, you may need to experiment a bit to find the right power for your plants.
