How to Choose the Best LED Grow Light: Buyer’s Guide
For a beginner trying their hand at growing plants indoors using LED grow light, it can seem like a daunting task to choose with so many options available in the market. Parameters such as light spectrum, PAR, wattage can leave many confused and wondering what’s really important. In this guide, we will address critical parameters that will help in choosing the best LED grow light. Having this complete understanding will help you delve into indoor gardening with enthusiasm.
Let’s go step by step into each of the ‘must have’ to consider prior to purchasing your LED grow light:
The size of your grow space is important because it will dictate the size and number of LED units you would need to purchase. Grow spaces sizes very greatly and it is absolutely important to measure your grow space in terms of length x breadth x height. A LED grow light manufacturer will design the grow light for a specific coverage area. Most common sized grow areas for hobbyists include 4’ x 4’, 3’ x 3’, and 2’ x 2’ spaces. Once you are through with the measurements of your grow space and know what area you need your LED grow light to cover, you can narrow down your search results by filtering to show LED grow lights specific to your required grow space.
While the length and breadth have been factored, the height of your grow space is also important and is measured in terms of light distance. Every grow light listing ideally should state the coverage area as well as the recommended light distance where the light distance is the distance between the grow light and the top part of your plants. You would not want your plants to grow too close to your light so you will need to factor this aspect as well.
If you plan to grow plants inside your home, you would not need plenty of LED grow lights. However, if the surface area is extensive like in the case of a greenhouse, you would have to consider purchasing several units of LED grow lights so that each plant receives optimum amount of light. For example, if you are growing in an 8’ x 8’ area, it is best to use four lights that cover a 4’ x 4’ area and for smaller areas, such as a 2’ x 4’ area, you can choose a light that is advertised to cover that area, or use two lights that each cover a 2’ x 2’ area.
Purchasing a LED grow light with full spectrum will go a long way in terms of helping your plant grow. A spectrum of light is the color emitted by the grow light and the different colors emitted at a certain energy created by photons are measured in nanometers (nm). The difference in the nm of a photon, or its color, changes its potential effectiveness to drive photosynthesis which is crucial for plant growth.
An LED grow light with full spectrum would mean it has red & blue spectrums and also infrared and ultraviolet. The blue light is needed more during the vegetation stage and red light is essential during the flowering stage. Although, blue and red light are most critical, UV and IR also needed but, in smaller amounts. Ideally, one should look for blues that have a range from 440-470 nm and reds in the range of 640-680 nm. Another advantage of full spectrum lights is that they run cool and don’t need any additional fans, they cost less overtime thus, being energy efficient. If a grow light listing does not show the spectrum, it is recommended to ask the manufacturer before purchasing it.
PAR (Photosynthetically Active Radiation)
A PAR is the amount of light that is actually available to be used during the photosynthesis process. LED grow lights can have different PAR values depending on the manufacturer and a light having a higher PAR doesn’t mean that the bulb is better. The PAR should be evenly distributed among the plants which is why it is also important to know the surface area as plants directly below the light will receive more PAR.
Consider reading the PAR chart shared by the manufacturer as it will have the PPFD readings which stands for Photosynthetic Photon Flux Density. To put it simply, it means the light that hits a certain area every second. The PAR chart is helpful as it will show you exactly how intense the light is over a given area and how the intensity is distributed. As a quick reference, one can know that plants in the veg stage need around 300 PPFD to 600 PPFD whereas plants in the flowering stage need at least 600 PPFD to 1000 PPFD. These PPFD numbers could vary depending on how hard you want to push your plants.
Depending on the growth stage of your plant, you would want to ensure that your plants receive the optimum amount of lighting right down to the exact hour. You can refer to the various phases and their requirement as follows:
Seedling Phase: 16 hours on, 8 hours off
Vegetative Phase: 18 hours on, 6 hours off
Flowering Phase: 12 hours on, 12 hours off
It is extremely important that light cycles are followed as it can severely impact or alter the growth and potency of your plants. There are LED lights in the market that are programmable and allow you to set schedules of when the light should turn on and off, so you don’t have to do it manually. Some lights may even allow you to adjust the intensity of the light as well as the spectrum so it would be suitable for the kinds of plants you’re growing. There are also LED lights with the veg/bloom switch feature where one can switch to either of the phases depending on the growth stage of your plant.
A LED grow light should have great electrical efficiency and be able to operate for at least 10-12 hours a day. Wattage (or watts) is a measure of energy consumption and when a LED grow light listing shows the number of watts, it indicates how much energy the grow light would consume. This directly relates to the electricity bill one can expect each month.
When researching a good LED light, you’ll need to thoroughly understand what the output is e.g. 1000w, 400w, 300w etc. The higher the watts, the less consumption of electricity thus, making it more cost effective.
Ease of Use
Often, you would have to adjust the position of your lamps based on the plant type and growth stage. In such cases, you would need a LED grow light which is easy to use and will let you fine tune it’s placement with little effort. Also, look for LED lights that are lightweight and easy to mount or hang in any part of your indoor garden.
It is important that the wavelength and light intensity are adjustable as well. One should look for LED lights that are easy to maintain, set up and ready to use straight out of the packaging without any additional costs for wiring, plugs, wall mounts etc.
LED grow lights are now the cutting-edge solution for indoor gardening and hence, when buying LED grow lights, one must consider its durability. The construction should be of high quality and the light units must not flicker often or produce too much heat.
As the plants need sufficient light to thrive, flickering lights will obstruct the process of photosynthesis and heated light may cause burning of the leaves or seedlings. Most often, if your LED light is made up of poor quality, it is more likely to get overheated.
If the working of your LED lights is for at least 15 hours a day, there is a high possibility of it being overheated. Excessive heat is harmful to the plants and the unit itself as well.
Opt for LED grow lights with an efficient cooling system. A good LED grow light would have a heatsink to dissipate the excess heat and prevent it from overheating.
The best LED grow lights are not very easy on the wallet and while they work flawlessly 99% of the time, there is also a possibility that a driver can fail or the LEDs go out or the fan breaks. In such unfortunate instances, knowing that the manufacturer will take care of it is reassuring.
LED grow light warranties vary from 1 year to 7 years. Most companies offer a 3-year warranty and you must consider reading the warranty terms and conditions on the manufacturer’s website. Most noted practice is that manufacturers will send a replacement part or the LED light free of cost if there are any issues with the fixture within the warranty period.
The cost of a LED grow light is of consideration to most people and the amount of money one is ready to shell out while purchasing LED grow lights would depend if the activity is being pursued as a hobby or business. For a hobbyist, the price point of the LED light is of high importance but for growing high value crops that quickly recoup the investment post harvest, one may want to invest in higher quality LED grow lights.
Usually, cheaper lights are smaller in size and work only for small plants like herbs, spices and some vegetables. Also, buying a cheap light could incur more expenses for future repairs, maintenance or replacements.
The points detailed in the buyer’s guide can help you navigate into the world of LED grow lights and trim down to the LED grow light of your choice for your indoor garden.
With LED grow lights being a revolutionary step in the world of horticulture, we hope this article helps you decide on your next best LED grow light to pursue your passion for gardening.
