What grow light is best for tomatoes?
If you are looking for the best led grow light for tomatoes in 2021, you want to ensure that you have one that works well with that particular type of plant. Below we review two types of lights that are proven to be extremely helpful for successful tomato growth.
01. KingLED Brand King Plus 2000 Watt LED Grow Light
This grow light is advertised as equivalent to a 2000 watt High Pressure Sodium grow light. Those are the gold standard when it comes to grow lights. In reality, this model of LED grow light is similar in light output to a 1400 watt HPS grow light. Like other LED lights, is energy efficient; it only uses 400 watts of electricity.
This grow light can put out full-spectrum light for tomatoes and other vegetables in a three foot by three foot area at an eighteen inch elevation. That’s enough for starter tomatoes. This grow light can provide supplemental light for tomatoes growing on a trellis in the window or a kitchen planter; in this case, it can provide light for a four by four area or larger.
It has blue light, red light, infrared and ultraviolet light that fosters both stem growth and fruiting. You won’t have your plants losing fruit because it can’t support them.
This may be the best led grow light for tomatoes for beginners. It has almost everything you need out of the box minus the planter and seeds. You get the grow light, hanging equipment, and protective glasses. Because it puts out UV, you need to wear protective glasses working around this grow light when it is on.
It runs hot, and it will get very hot if the cooling fans conk out. Make sure the fans are working, and ensure that you have adequate heat exhaust if you don’t want the plants to suffer due to the heat. Some units even ship without the heat sink, and that can cause the PCB to overheat and die.
- Full spectrum grow light
- Energy efficient
- Tends to get hot
- Closer to 1400 than advertised 2000 watts
02. Parfactworks Brand Model RA2000 Grow Light
Parfactworks is a second tier brand of grow lights. You probably haven’t heard of them, but you should consider their products given the price. The model RA2000 grow light is a full spectrum grow light. For example, it puts out some orange and green light as well as blue and red. It doesn’t put out the mostly red light required for lettuce and other leafy plants, but it is fine for fruiting vines like tomatoes. It may not be enough for flowers by itself, but it can provide supplemental light for indoor plants.
This unit can cover a three foot by three foot area that is flowering or a four foot by four foot area of seedlings. It can provide supplemental light for a four foot by four foot area.
This unit has far more cooling fans than other LED grow lights. It won’t overheat your plants trying to provide adequate light for them. It achieves this in part by having reflectors above the lights to direct as much light as possible downward. Make sure they are lined up correctly or the light distribution won’t be correct. These can shift during shipping.
It is energy efficient. It only pulls 250 watts.
The fans are loud. If any of the fans go out, the boards will overheat, and that can cause things to short out.
It doesn’t have a timer, but that’s generally something you have to pay extra for, anyway.
- Energy efficient
- Good overall value
- Loud fans
- Prone to overheating
03.The Viparspectra 450 Watt LED reflector-series
This grow light is one of the best grow lights for vegetables. It is perhaps the best led grow light for tomatoes for several reasons.
Supports All Phases of Growth
This grow light puts out a balanced mix of red and blue light. It helps seedlings to grow and fosters leaf growth. It ranks as the best led grow light for tomatoes because its blue light output is enough to make stems strong while encouraging flower and fruit production. Note that these lights are great for tomatoes and many other vegetables but not strong enough for orchids or sun-loving plants.
It Covers a Decent Area
This grow light covers a two and a half foot by two and a half foot area when the light is two feet above the target area. If you put it two feet above the plants, it only covers a two foot by two foot area. This is enough lit area to enhance the growth of two staked tomato plants. Or you can accelerate the growth of even more seedlings before you plant them outside. If you plant them outside, they’ll need to be one to two feet apart if staked, two to three feet apart if caged.
The reflector maximizes the light received by the plants while minimizing energy consumption. This grow light generates as much light as a 400 Watt metal hydride or HPS light, yet it only consumes 200 watts. This means you’ll save money on electricity for this grow light as well as get a unit cheaper than HPS grow lights.
It Won’t Burn Your Plants – Literally
This grow light has fast, quiet fans to prevent the LED grow light from overheating and burning your plants. Its cooling heat sinks prevent the LED itself from generating so much heat that makes a grow tent or living room too hot. That makes this grow lamp 70% cooler than comparable high intensity discharge lamps.
Be sure to place the lamp somewhere that it has adequate airflow, since a blocked fan cannot keep things cool; in a worst case scenario, it can get so hot that the lenses melt. This means you can’t put the light right at the top of an enclosed grow tent if the tent’s sides are trapping the exhaust from the fans.
Note that this grow lamp is not to be used outdoors. That makes this the best led grow light for tomatoes if you’re growing them in an enclosed space.
The Viparspectra 450 watt grow lamp comes with a three year warranty. You have thirty days to return it if dissatisfied. The challenge you may face is getting the warranty honored if you used the light at all, so if it has issues, return it as soon as possible.
Everything in One Package
The Viparspectra grow lamp kit comes with the one large grow light, a hanging kit and a single six foot power cord. You don’t need extra ballast to make it work. You can control it via a timer, but it does not come with a timer.
04. Osunby LED Grow Light

If you want to keep them inside, that is completely possible with this type of grow light. Start off seedlings near the end of the winter indoors.

Tomatoes can be very fussy plants when they are first started, and this type of grow light can aid in getting them the best start. This grow light is affordable and dependable and easy to set up. There are no complicated wiring needs either, so the cost that is saved on hiring an electrician to ensure all lighting is set up properly can be put towards higher quality lights such as these.
These lights do give off some heat, but it is only enough to warm the seedlings and assist tomatoes in growing taller, faster and straighter than without grow lights.

Can you grow tomatoes with LED lights?
The short answer is yes. The longer answer is that the growth of tomatoes with LED lights is a process. There are two types of tomato plants, those
which produce tomatoes, all ripening at the same time and then the plant is spent – reaching the end of its life. The other type of plant offers constant growth and production of tomatoes at several times throughout the year. This plant produces fruit as the vine continues to grow and develop which means that it must be constantly pruned in order for the plant to continue to grow.
The most common tomato varieties are Green Zebra, Independence Day, Early Girl, Big Beef, Better Boy, Juliet, Sun sugar, Jersey, San Marzano, Cherokee Purple, Amish Paste, Celebrity, Cherokee Purple, Mortgage Lifter, Yellow Pear, Black Krim, Brandy wine and Big Boy. Each variety has a different size plant and growing season length so you need to educate yourself on which variety is the best for indoor growing. Of course, you can try many varieties and see how they develop or grow over time.
You also need to decide if the plant is going to be staked or allowed to sprawl out in order to determine which plants are most suitable for indoor growing.LED grow lights are perfect for growing tomatoes because tomatoes need a full eight hours of light each day to produce tomatoes.
Tomatoes will slow their growth if they experience any cold temperatures so LED grow lights help to keep the plants at their preferred temperature of between 71 and 75 degrees Fahrenheit for the optimum growth of your plants.
Using a good quality grow light will let you control the amount of light that your plants receive. When the plants are being germinated they should receive a full 12 hours of light in the first 3 to 5 weeks of their life. After that initial germination period, the amount of light should be
increase to as much as 16 hours daily for the next three weeks. After that period of time, the amount of illumination can be lowered to 10 hours daily.
LED grow lights offer many benefits to growing tomato plants, including: ·
A markedly lower consumption of energy as compared to sodium lights A noticeable increase in the volume of tomato fruit;The promotion of germination and growth of tomatoes The ability to grow and cultivate plants all year long;
How many lumens do tomato seedlings need?
Tomato seedlings need an average of 7000 lumens per square foot of plants being grown. The minimum amount of lighting should be 2000
lumens per square foot with a mid-range amount of light being 5000 lumens per square foot. During the phase where plants are reproducing and flowering they require a minimum of 2000 to 3000 lumens per square foot.
Led grow Light Distance Tomato Seedlings
The goal is to get your seedlings usable light about 8 – 12 inches above the plants. The amount of light helps the seedlings to grow as fast as you give them light. Less light means that they will grow a little bit slower. You need to deliver 120 – 150 micro-moles of light to the seedlings per minute to help them grow to their capacity.
When you want to know what is the best LED grow light for tomatoes, it is a good rule of thumb to use a light that delivers the proper minimum amount of light as described here to ensure that your seedlings are getting the proper amount of light.
