How to Choose Grow Lights
Here are the most important aspects you should consider before buying a grow light for your plants. It's also important to know what grow lights are and how they work before making a choice.
The size of the grow light you’ll choose depends on the number of plants that you want to illuminate and how much space they need from the light. If it’s just a plant or two, their needs will differ from a whole indoor garden.
How much grow space will the light have anyway? This will directly affect your choice in terms of size. In addition, you should consider the light’s level of portability if you’re planning to move it around.
Grow lights come in a variety of types, the most common of which is freestanding. Freestanding lights are those that can stand on their own. They come in trays or on stands. In addition, Their popularity stems from their convenience and ease of use.
We highly recommend them for growing seedlings. That being said, they come in fixed sizes, meaning that you can’t expand them.
Stackable Modular Units
As the name suggests, modular units are stackable so that you can expand your indoor garden freely. You start with what you need at the moment, then expand vertically according to your gardening needs with additional racks. You’ll get a lot more options in terms of size as well.
Not everyone has the space for an entire garden. It’s becoming more common to grow plants indoors on countertops, thanks to countertop models. These indoor grow lights allow for space-saving gardening with their compact design. In addition, they’re great for an aesthetically pleasing view.
Light bulbs are a great option for DIY enthusiasts that love to install and customize their own setups instead of buying the whole thing intact. Plus, this no-fuss option means that your complete focus will be on the light’s performance when choosing, so it’s quite straightforward.
Some plants don’t like to have their light right above them. So, if you want to grow houseplants and succulents indoors, a home lamp would be the ideal choice. Like freestanding lights, they’re also good for growing seedlings and even seed germination.
Quick Pro Tip: If you’re growing seedlings, pair your home lamps with sterilized soil for the best bacteria and fungus-free results.
Cool, Warm, and Full-Spectrum
You may have heard these words before as a beginner without context and wondered what they even mean.
Basically, cool, warm, and full-spectrum refer to the light’s temperature, especially on the Kelvin scale. So, you’ll find numbers ranging from 2,500K to 6,400K, and the higher the number, the cooler the light will be, and vice versa.
Cool light is more desirable for vegetative growth, so it produces greener leafy greens. On the other hand, warm light is better for flower production and growing fruits.
If you want to skip the guesswork and get the best of both worlds, there’s no better option than a full-spectrum light. In fact, most people use full-spectrum grow lights because they’re the best at imitating natural sunlight that has both the warm and cool in it, which enables them to grow all kinds of plants.
Ease of Use
What’s the point of a grow light if it doesn’t make your life easier? Get grow lights that you can install, especially if you’re just starting out. Check the instructions before you buy it and see if it comes with all the needed connections or if you’ll have to buy something yourself.
Also, consider if the light you have in mind has helpful features, such as height adjustability, timers, remote control, casters, and self-watering.
Quick Pro Tip: Grow lights can make the soil dry faster, so check your plants daily to monitor their water needs.
LED vs. Fluorescent Bulbs
Each of these grow lights have their devoted fans. These two are the most popular, and people are abandoning their MH and HPS lights for them because they save money while consuming less energy and having less heat output. So, which one should you get?
Generally speaking, LED is the more advanced option and has impressive longevity, so it’s more expensive initially. It’s more energy-efficient since it uses less energy for the same light output that its fluorescent counterpart uses. Finally, it has a greater spectrum of light than fluorescent.
On the other hand, fluorescent light is cool, meaning that it’s good for lush foliage. Since this light intensity is low, you should place it inches away from the plant. Still, it provides good coverage. Fluorescent comes in two categories: tube lights and compact fluorescent lamps or CFL.
Frequently Asked Questions
Let's answer some of the most common questions people have.
What Lights Do Professional Growers Use?
It depends on their biggest priority. If they’re looking for energy efficiency, they go for LED and fluorescent. Their more expensive counterparts, MH and HPS, have different purposes. MH light is used by professionals in the vegetative phase, while HPS light is for flowering.
That being said, LED and fluorescent lights have taken over the market in the last few years, thanks to their efficiency. T5 bulbs seem to be very popular right now.
Will Any LED Light Work as a Grow Light?
Technically, you can use any LED light. However, the LED bulb that you already have around won’t perform as well as an LED grow lamp that’s meant for that purpose. Also regular incandescent bulbs won't do the trick unfortunately, as incandescent light is far too hot for most plants to grow.
If you’re growing leafy greens, it’ll be easy to grow with most LED bulbs. That being said, if you want to induce flowering, you’ll need more powerful LED bulbs.
Should I Turn off the Grow Light at Night?
Yes. You should adjust the light to meet the plant’s light-dark cycle, as grow light is supposed to mimic sunlight. Sunlight isn’t around all day, and neither should the grow light.
However, the duration of the dark differs from one plant to another, so do your research and set a timer to remind yourself to turn the light on/off. Otherwise, the plant could burn, and the soil could dry out.
How Many Hours a Day Should Grow Lights Be On?
It differs depending on the light requirements of the plant you’re growing. The most common range for indoor plants is 12 to 14 hours. Nonetheless, some plants don’t need more than 6 hours of light a day, while seedlings need up to 18. Your best bet is to do some research on your plants and set a timer accordingly.
Can Too Much Light Kill a Plant?
Definitely, since all plants have their own light requirements, exceeding them will lead to drastic results. Just like how humans get sunburned if they stay under sunlight for too long or are exposed to too much light, plants act the same. If your plants grow in shade or low-light conditions, you shouldn’t push them to their limits so that they remain alive and healthy.
