Question 1

Why Do You Need a Grow Light?

Accepted Answer

The first and foremost question that many growers tend to ask is - why do you need an LED grow light? When you are growing your marijuana indoors, you do need an LED grow light because this is what will replace the natural light of the sun indoors! Since sunlight is the most essential thing required to grow a plant and since it cannot be provided naturally indoors, you would require to buy a grow light.rnrnThe grow lights are needed by growers to grow marijuana indoors because it is in the direction of these grow lights that the stem of the plants will grow and it is with the help of these grow lights that the process of photosynthesis will be able to take place. Photosynthesis is really important for the healthy growth of any plant as that is the process via which plants convert sunlight into energy! Hence, if there are no grow lights the plant will not be able to survive as it will not be able to generate energy! This is primarily why grow lights are important. rn

Question 2

What is an LED Grow Light?

Accepted Answer

An LED grow light is a modern grow light which is used to provide light and heat to the plants. These grow lights make use of electricity to produce light using light emitting diodes placed on circuit boards. LED grow lights fare special because they can provide lights of a large spectrum of wavelength, and users can simply hit a switch to change from vegetative mode to blooming mode. LED grow lights also have a longer lifespan compared to practically all other grow lights in the markets and are being preferred by a large number of modern day growers. rn

Question 3

Difference Between LED Grow Light and Fluorescent Lights?

Accepted Answer

Fluorescent grow lights have been in use for a really long time. They include two major types of lights - the T-lights and the CFL lights. CFL lights, as we know them to be, are the household lights and bulbs that we use for providing lighting in our homes. T-lights are lights of varying intensities which come along with a complete reflector setup and provide a fairly bright amount of light to the plants. One major difference between fluorescent grow lights vs LED grow lights is that of the fact that fluorescent grow lights make use of mercury vapor to convert electricity into light. However, in case of LED grow lights, there is no such toxic chemical involved. rnrnAnother major difference between these two lights is that LED lights are way more energy efficient when compared to fluorescent grow lights. LED lights can even last for much longer than CFL or T-lights. When you compare the cost, however, fluorescent grow lights might appear cheaper - but when you do an overall analysis, LED grow lights are the clear cut winner here!

Question 4

How do LED Grow Lights Work?

Accepted Answer

To understand how LED grow lights work, you essentially need to see these grow lights as semiconductors that allow the passage of electricity through a circuit. To further simplify it, there is a small piece of silicon with a Positive side and a Negative side to it and between the two sides there’s a small gap. When electric current is passed through the circuit, electrons tend to jump between the two sides - thereby resulting in producing light. This is the simplest explanation as to how LED grow lights work by converting electric current into light.

Question 5

What are the Benefits of Using LED Grow Lights?

Accepted Answer

There are a number of benefits of using LED grow lights. First of all, they are the most electricity and energy efficient option that growers have. Grow lights tend to consume a lot of electricity, especially if you use primitive forms of lights such as High Pressure Sodium lights or Metal Halides. However, these modern-day lights are much more energy efficient and provide a much higher output of light by converting a lesser amount of electricity. rnrnApart from that, another huge benefit of using LED grow lights over other types of grow lights is that LED grow lights can last much, much, longer compared to them. LED grow lights have an average life span of 40,000 hours - which is massive. Furthermore, if they go bad, they are easy to dispose as well and you can be assured that they will not cause you or the nature any harm because they do not have any toxic chemicals powering them.

Question 6

How To Know If Your Plants Are Getting Enough Light?

How to Choose The Best LED Grow Lights in 2021?

Accepted Answer

Most grow lights today are full spectrum LED grow lights so make sure you are going for a full-spectrum light and not for one which has a partial spectrum. rnrnWhile these are the primary considerations, you must also look at certain secondary things such as if the light you are planning to buy water-proof? How is the heat dissipation system of the grow light you are considering to buy? Also check out the warranty period and whether you can return the product if you are dissatisfied with it. The lifetime of the product is also something that buyers must consider. Most LED lights today come with an average lifespan of about 50,000 hours. Keeping all these things in mind would help you choose the best LED grow light in 2021.

Question 8

How far should LED Grow Lights be from plants?

Accepted Answer

LED grow lights need to be kept at an appropriate distance from the plants - keep them too near the plant and you risk burning it and keep it too near and then you would risk not providing adequate light to the plant (particularly the lower portions). Hence you need to ensure that you keep the lights hung at just the right distance. The most basic way to do this is known as ‘back of the hand test’. Place your hand on top of the plant and keep moving the light slowly downwards till you begin to feel hot and then move it significantly upwards. The light, as a rule of thumb, needs to be farther from the plant during the growth phase buy nearer during the flowering phase. The distance should be adjusted till you come to the perfect position.

Question 9

These lights are designed to help you grow indoors, just like you can grow in sunlight outdoors or way simpler.rn

Question 10

How many watts per square foot for LED Grow Lights?rn

Accepted Answer

Grow lights need to perform with efficiency and power to mimic sunlight, and there should be enough power required to do so. Therefore, grow light with 50 to 80 watts per square foot of operation will be needed for the desired result. Lights with below the stated watts will be able to perform for your plants but will not be as efficient. Heat and light will be ideal with 50 watts and above of watts per square foot.rn

However, the UV light present may prove harmful for your eyes if you stare for an extended period of time.rn

Question 12

What size LED Grow Light do I need?rn

Accepted Answer

Your grow light must be in accordance with your grow area and spread of your plants. You need a size that covers your grow area with its efficiency with wattage output. Like a 250 watts of grow light is ideal for grow space of about 3 x 3 feet of area, a 400 watts will cover 4x4, a 600 watts will cover 6x6 feet and likewise. You will need coverage the most when your plants begin to grow and spread along with enough output. So, measure your grow area and order a size close to it or order in multiples. You can check out amazing grow lights in our article above.rn

Question 13

How many plants can I grow with a 1000w LED light?rn

Accepted Answer

A 1000 watt LED light is ideal for a growing area of about 7x7 feet and more, and with that, a user will be able to grow 1 to 20 plants. The number of plants will be dependent on the strain, size of plants, and to the extent, they grow. Also, the efficiency of the light and output will determine the number of plants you can grow below it.rn
