Bright light is super-important for healthy tomato seedlings! As soon as they sprout, they’ll reach up for sunbeams (or fluorescent beams). Seedlings need 12-18 hours of light each day. Do yourself a favor and give it to them.
What kind of grow light for tomato seedlings?
Full-spectrum grow lights are the best grow light for tomatoes because they emit all of the wavelengths of light that plants need. They are more expensive than other types of grow lights, but they are worth the investment if you want to get the best results.
How far should LED grow lights be from tomato seedlings?
Their distance from the plants should be between 24 and 60 inches (60 and 150 cm). Moreover, as the plants get taller, you’ll need to move the lights further away as well.
Can you give tomato seedlings too much light?
It is true that your seedlings need bright light to grow healthy and strong—but, too bright a LED light could actually damage them if it’s too close – plus, seedlings also need a period of darkness in order to thrive.
Will tomato plants grow under LED lights?
The quality of your tomatoes will improve if you use LED grow lights for tomatoes with a customized spectrum. The right combination of red and blue LEDs provides faster ripening, higher yields and a more uniform plant balance. Furthermore, the tomatoes have more weight and a better flavor.
How close should my LED light be to my seedlings?

What is the best grow light for seedlings?

Can you leave a grow light on too long?
A: In general, you should not leave grow lights on 24/7. Plants need a light-dark cycle to develop properly. It’s believed that they truly do “rest” during periods of darkness, and probably use this time to move nutrients into their extremities while taking a break from growing.
Can you leave grow lights on 24 hours a day for tomatoes?
A. No. Tomato plants need at least 6-8 hours of darkness each day. Turn off the lights at least part of the time.
How high should a grow light be above tomato seedlings?
Our recommended grow light distance for fruiting and flowering plants (eg tomatoes, peppers) is 2 – 10 inches, again based on the same wattage/optics variables.
Can LED lights burn seedlings?
While LED lights do produce some heat, they deal with that heat more effectively than other light types. Plants can grow much closer to LEDs than other lighting types because of this. Usually crops can grow right up to the light without burning.
How many hours of artificial light do seedlings need?
14 to 16 hours
In general, seedlings should receive roughly 14 to 16 hours of light a day when situated in a south-facing window. This can be very difficult to achieve, and most growers opt to use artificial lights for their seedlings. These fluorescent lights should be left on for 12 to 16 hours a day.
How do I know if my seedlings are getting too much light?
Symptoms of too much light on plants
- Droopy leaves. One of the chief signs your plant is getting too much light is drooping leaves.
- Brown patches. Plants may develop brown patches throughout their leaves that indicate it is getting too much light.
- Faded look.
- Hot plant surface.
- Crispy leaves.
- Dried out soil.
When should you start tomato plants indoors?

How many hours should a grow light be on tomatoes?
12 -16 hours
Tomatoes needs at least 8 hours a day of sunlight to produce fruit, but aim to provide 12 -16 hours of light for the best growing results. Tomato plants are day-neutral, meaning that they will flower independently of the day length.
Can you grow tomatoes with grow lights indoors?
Tomato grow lights (or plant grow lights) allow you to start seedlings and grow tomatoes indoors, even during the off season or when temperatures are cold outside.
How many plants can I grow with a 1000W LED light?
6 plants
Yield Lab 1000W HPS+MH Cool Hood Reflector Grow Light Kit (Price: $239.95) — With a 1000w grow light, you’ll get 130,000 lumens from an HPS bulb and 110,000 lumens from an MH bulb. That’s sufficient to provide coverage for up to 6 plants.
How high should my LED light be above my plants?
So the ideal way to use an LED light is to place it as close as possible to the canopy without burning the plants. In well-ventilated areas, we have found the mounting height to be as close as 6 inches.
How many watts light for seedlings?
The seedlings of the indoor led grow lights need about 32 watts per square foot, while CFL needs 100 watts for each plant. They also need the right color temperature to grow and thrive, so choose a temperature range of 3500 to 6500 Kelvin.
Is red or blue light better for seedlings?
Light Color
Red light stimulates vegetative growth and flowering (but if a plant gets too much, it will become tall and spindly). Blue light regulates plant growth, which makes it ideal for growing foliage plants and short, stocky seedlings (but too much will result in stunted plants).
Can any LED light be used as a grow light?
You can use regular LEDs but you’ll get better results with LED grow lights. LED bulbs and strips usually produce white light, which is helpful for general plant growth. However, plants really need blue and red light to thrive.
