Best Small Grow Lights

The outlook of the government and citizens towards marijuana has witnessed a drastic change over the past decade. With almost all US states having legalized marijuana for medicinal purposes and some even allowing the recreational consumption of weed, the legalization movement is at its peak and marijuana is no longer a taboo. In these times, if you want some good weed you can get it from a licensed store and no longer need to ‘score’ it form hush-hush places. However, there’s another alternative: you can grow your own weed. Personal-scale growers are increasing with every passing day – and in this article, we shall be discussing the best small grow lights for growing marijuana.

We shall be addressing what lighting is and why it is important, but our focus here is on small grow lights which are important for small-scale growers. Not all growers want to grow weed in bulk – most grow lights suit the needs of larger growers but there are certain specialized products that are made for small scale growers too. In this article, those specific needs will be addressed. 

Small grow lights are very important and growers who buy them need to understand the minute details about these grow lights which are often accidentally missed. These grow lights are created to serve a specific kind of purpose and are meant for a specific kind of grower. In addition to reviewing the best small grow lights in 2020, we shall also be talking about the features that you need to look up – as a part of a buyer’s guide.

Each of the products that we have reviewed are of high quality and will help small-scale growers grow their weed under the perfect conditions! Let us begin by understanding the role that light plays in a plant’s life cycle and what grow lights are:

Why Is Light Important for Marijuana Plants?

Marijuana plants need light all over their main stages of growth. While as a seed or a germinating seed they don’t need light, but right from the seedling stage all the way to the day of the harvest, these plants need a lot of sunlight. This is because light consists of rays of different colors and wavelengths – the blues (cooler lights) are needed for the vegetative growth of the plant and helps it mature into the flowering stage – seedlings and vegetative plants need a lot of blue light (up to 20-22 hours). As the plant matures into pre-flowering lighting is gradually reduced to about 14 to 16 hours and then growers trigger their plants to enter the flowering stage by reducing the light to 10-12 hours. 

Besides this, lighting is also important for the process of photosynthesis, for the proper exchange of respiratory gases, for the proper breakdown of sugars, etc. Even the generation of chlorophyll is dependent upon lighting. The amount of THC and CBD also depends upon certain aspects of the light and the improvement of root mass and spacing of branches is also a function where light aids the plants. Hence, lighting is extremely important for marijuana growers. 

Naturally, you get light from the sun when your plant grows outdoors. However, when you grow your weed indoors, you need to provide it with an artificial source of lighting which comes in the name of grow lights. These grow lights help growers recreate light very similar to natural sunlight inside their grow tents or grow rooms. These artificial lights help your plants grow under ideal conditions as you can move them up and about, or angle them at special positions – and turn them on and off at will, giving you control over the right kind of distance, angle, and time that your plants need for best possible growth. Let us now take a look at the best options we have when it comes to small-sized grow lights:

10 Best Small Grow Lights in 2020

‘Small’ grow lights basically refer to the area that is covered by the lighting. Large grow lights tend to cover large areas – these are grow lights which are either clip-ons, strips, or lights that cover below 3×3 grow tents.

Buyer’s Guide to Small LED Grow Lights:

There often is a lot of confusion about small-sized LED grow lights in the markets. While regular-sized grow lights are already an established commodity and growers know what they want, small grow lights can be quite a challenge to buy. To make this decision-making process easier, we have come up with a checklist of some questions that you need to ask yourself before you decide on which grow light you are finally going to buy. Considering that most of these grow lights are quite inexpensive, most growers don’t really go through this and end up getting the wrong lights! We hope this buyer’s guide helps you pick the perfect small-sized LED grow light for your marijuana plants:

1. How Much Area Does the Light Cover?

You must always know how much area the light covers because then you would know if it is the right size to cover your plants. A larger light is alright to buy but a light that provides a smaller coverage than the area your plants are spread out in doesn’t make sense unless you’re planning on buying multiple such lights. 

2. Is it a Full-Spectrum Light?

Always try and get a full-spectrum light instead of a light that offers a dedicated wavelength. This will ensure that you will not need to change the lighting from time to time during the different phases of your plant’s growth. 

3. Is it an LED Light?

Using an LED light is always better in comparison to using HPS or Fluorescent lights because they are much lighter in weight, consume very little power, and can last for a really long time in comparison to the other, older forms of lighting. 

4. How Much Power Does the Light Consume?

You need to know how much power your light is consuming. If the light’s name states 150W in it, it does not necessarily mean it consumes so much power! LED lights tend to consume much lesser power and the exact details will be written on the packaging. You need to know what is the exact power draw. This is the biggest benefit of using LED lights that they consume so little power that you end up saving a ton of money in comparison with HPS lights. 

5. What is the Expected Lifespan of the Light?

You must know what is the expected lifespan of your grow light – most LED lights can last for 50,000 hours. Some good quality lights even go till 100,000 hours or more. Do check this parameter before you buy your small grow light.

6. Does it Support Dimmability? 

Dimmability and timers are two critical features which are present in almost all small LED lights. Do make sure that the one that you are choosing offers these features! 

7. What are the Cost and Warranty Details?  

This isn’t even something that we need to tell you but the cost and warranty do matter quite a lot and make sure you’re getting a good deal there! 

Frequently Asked Questions (FAQs) About LED Grow Lights

We keep getting emails and DMs about these grow lights – hence we have picked up a set of questions that we get asked the most so that everyone can benefit from the answers at a single place. Going through them will help improve your understanding of these lights 

1. Where can I buy small grow lights?

Small grow lights are easily available on Amazon. You can also find them in your local gardening stores or super speciality stores. Sometimes if you are lucky, you can even find them in a nearby hardware store which sells lighting equipment as well. Although Amazon remains the best option for buyers because of the variety that they get there. 

2. Who is a small grow light really for?

A small grow light is meant for growers who are growing at a very small scale. These are mostly personal growers. However, if we ignore the marijuana part for a bit, these are also great for growers who are growing succulents! 

3. Why is there no warranty on these grow lights? 

Not all grow lights come with a warranty period. While you might find some of them offering you a two or even a three-year warranty, most of them don’t. This is because they are a very low cost and low margin product.

4. Are clip-on lights or LED strips as effective as a proper grow light? 

Getting a proper panel LED light is always a better option in comparison to getting an LED strip or a clip-on light. We have provided you with all three options which you can buy based on your needs. Clip-on lights and strips are great for those growers who want additional lighting but don’t necessarily rely on them for the primary source. However, they might suit those who are growing succulents or other smaller plants with lesser lighting needs. 


Not every grower wants to grow a lot of weed. Most marijuana growers want to grow it only for their personal consumption or for a close circle. Hence, for small-scale needs, growers need to have a very clear idea about the kind of grow lights that they can make use of! Most growers actually prefer to use these grow lights as additional lighting equipment to boost the growth of their plants. We hope that we have answered all your questions regarding the best small grow lights in 2020.
