As a grower, one of the most important bits of equipment you need is your light. It’s important to feed your plants high-quality light so they can produce high-quality yields.
We recommend you to use good LED grow lights because of their energy efficiency, full spectrum, and durability. However, it’s not an easy task to find the right light for your plants.
Today, we will help you to learn about all the essential info you need to know about this topic.
Do LED Grow Light Work for Growing Plants?
LEDs grow lights actually are small electronic components. They are made from 2 different types of semiconductor material. They include electrons and holes. The first one is a negative charge, and another one is a positive charge.
If the LED grows light applies properly voltage, electrons and holes will collide releasing energy.
Color variation of the LED grows lights influence plant growth. In fact, they affect the root and flower formation due to red and blue light spectra. Some of LED grow light system offers more spectrums, so they can give you higher quality plants.
What size LED Grow Light Do you need?
In order to determine the size of LED grow light you need, you have to determine the exact size of your grow space first.
The size of your grow space
If you are growing cannabis, you need to use a minimum of 50w of light to cover each square foot. Then, your plants can get lots of energy to produce big potent buds. Therefore, it’s important to determine the square footage of your grow space.
How many plants can you grow?
Generally, you have to give each cannabis plant at least 1square foot of space. An essential rule of the process is to grow between 1-6 plants in a large 5-gallon fabric container. In fact, most LED grow lights are capable of covering about 1-6 plants.
In order to grow any more plants, you need to buy multiple lights in order to hang side by side. It will help to cover the entire canopy.
You will need to give your plants around the shaft of the power (25w) during their vegetation stage. Most of the lighting systems now are designed with VEG and Bloom switches that are essential for your plants during the vegetation and flowering stages.
Which LED Grow Light Should You Choose?
If you still wonder if which LED grow light you should choose, let’s take a look at a detailed list below. We will give you the name of the best grow lights on the market today. They may be helpful for you:
- Viparspectra 300w LED grow light
- Roleadro 300w LED grow light
- MarsHydro 300w LED grow light
Three LED grow lights are great choices for a small grow space. You should consider using them to set up between 1-4 plants. They also are for a 1 to 4 square foot grow space.
To decide which one is the best for your crops. Don’t forget to read all the reviews of customers and consider before you make your decision.
How Far Should LED Grow Lights be from Plants?
If you want to grow strong and healthier plants, you need the right distance from LED to grow lights to plants. Also, this helps to make sure the lights won’t burn your plants out. Always remember that LED grows lights can burn your plants if you place them too close your plants.
In fact, there will be yellow spots all over your plant’s leaves if you let them be overexposed to their light source. Also, this can lead to nutrient deficiencies.
There are various distances. Therefore, we will have no specific distance of your LED grow lights from your crops. Then, it’s essential to take a look at the shape, size, as well as the wattage of the LED grow lights you use.
It’s important to check the specifications of the lighting system you have. If there are no recommendations when it comes to the distance between your LED grow light and your plants, you should contact the manufacturer.
How Many Watts Should My LED Grow Light be?
Nowadays, LED bulbs have become one of the most effective ways to grow your plants indoors. They mainly come in three models, including 3w, 5w, and 10w.
The fact is that a 3w LED bulb can be able to run potential at 4w though its lifespan may be reduced. Actually, these measurements are only an estimate of the manufacturers.
However, it’s easy to realize that a 5w can give better light penetration compared to a 3w because it’s made on a larger chip.
You can consider purchasing COB lights. They are known as relatively new technology. These lights packages many 3w or 5w LED chips. They promise to give your plants greater light intensity as well as increased penetration rates.
In order to help you know how many watts you need for your grow area. We will give you the following bullet points:
- 1 by 1 – 32w
- 2 by 2 – 128w
- 3 by 3 – 288w
- 4 by 4 – 512w
- 6 by 6 – 1152w
Is Watts a Reliable Measurement of Light Output?
This is just a unit measuring energy. Therefore, you can’t determine the quality of light a LED grow light produces based on it. Normally, ones with higher wattage will produce more light.
According to many growers, the optimal number is around 300-500W per square meter. Therefore, you should consider using a 400-600W LED grow light.
In order to get a quality to grow light for your indoor plants, you also need to pay attention to color temperature, light intensity, and light wavelengths. They are also important measurements.
