Seedlings need light as soon as they emerge from the soil. Light is essential for their growth and development, and without it, they can become weak and leggy.
So let us investigate more
Seedlings need light as soon as they emerge from the soil. Light is essential for their growth and development, as it plays a crucial role in photosynthesis, the process by which plants convert light energy into chemical energy. Without sufficient light, seedlings can become weak and leggy, negatively impacting their overall health.
An interesting quote from renowned botanist Luther Burbank sheds light on the significance of light for plants and seedlings: “Flowers always make people better, happier, and more helpful; they are sunshine, food, and medicine to the soul.” This quote emphasizes the importance of light, which is essentially sunshine, for the well-being and vitality of plants.
Here are some additional interesting facts about seedlings and their need for light:
-
Different plants have different requirements for light intensity and duration. Some species thrive in full sunlight, while others prefer partially shaded areas.
-
When seedlings lack adequate light, they often exhibit symptoms such as elongated stems, pale or yellowish leaves, and a weak overall appearance. This is known as etiolation.
-
Light serves as a signal for seedlings to determine the direction of growth. This phenomenon, called phototropism, ensures that plants orient themselves towards a light source, allowing for optimal light absorption.
-
The color of light can influence the growth and development of seedlings. Red and blue light are particularly important in promoting photosynthesis and healthy growth, while green light is less effective in stimulating plant growth.
In order to provide a more structured overview of the light requirements for various plants, here is a simple table highlighting some popular plant species and their preferred light conditions:
| Plant Species | Light Requirement |
|---|---|
| Tomato | Full sunlight |
| Peace Lily | Partial shade |
| Zinnia | Full sunlight |
| Spider Plant | Indirect sunlight |
| Basil | Full sunlight |
In conclusion, seedlings require light as soon as they emerge from the soil in order to support their growth and development. The significance of light cannot be overstated, as it provides energy for photosynthesis and influences the overall health and vigour of seedlings. Understanding the specific light requirements of different plant species can help gardeners provide the optimal conditions for successful cultivation.

Other approaches of answering your query
The answer to this one is simple. Your grow lights should be turned on (or your seedlings should be put under lights) as soon as the first seed starts to sprout. Many types of seedlings grow very fast, and they will begin reaching for the light as soon as they emerge. So give them plenty of it right from the start.
Most seedlings require 14 to 16 hours of light per day. It can be a demanding schedule to accommodate, which is why many gardeners gain the upper hand by hooking up the grow lights to a timer.
It is true that seedlings need lots of bright light to grow healthy and strong—but they also need a period of darkness in order to thrive. In general, seedlings should receive roughly 14 to 16 hours of light each day.
More intriguing questions on the topic
Do seedlings need light after germination?
Your seedlings will need light, but they also need periods of rest (darkness) too. A good rule of thumb is to turn the grow lamps off when you go to sleep, and turn them on when you wake up (or use a timer). Read all about different types of grow lights here. Seedlings need blue night and red light.
Also Know, At what point do seedlings need sunlight?
Answer will be: Days 1 – 3: Place your seedlings outdoors in a shady spot that will only get 3-5 hours of direct sunlight throughout the day. Days 4 – 5: Place your seedlings in a slightly sunnier spot that will get about 5-6 hours of direct sunlight. Days 6 – 7: Place your seedlings in a full sun spot (6+ hours of direct sunlight).
In respect to this, How many hours of darkness do seedlings need? Plants need to sleep. They perform important respiratory functions at night. Seedlings should have at least 6 hours of darkness per day, and more mature plants at least 8-10 hours a day.
In this regard, How far should LED lights be from seedlings?
As a response to this: As an unofficial rule of thumb, many growers work on the basis that: You need 20-40 watts of power per square foot. Lower wattage LEDs of around 200 watts should sit between 12-20 inches from the top of the plant. Higher wattage LEDs of 1000 watts and above should sit between 36-46 inches from the top of the plant.
Keeping this in view, How many hours a day should I Light my seedlings?
Response will be: If they start getting tall or growing sideways, then give them another hour or two of light. Some people like to follow a 12/12 lighting cycle for their seedlings. That means the lights stay on for 12 hours a day, and they are off for 12 hours at night.
Can you put seedlings under grow lights?
No, and you should not put seedlings under grow lights for 24 hours a day. Just like us, they need to rest at night. It’s important to follow a normal sunlight pattern, or your seedlings will suffer when it’s time to move them outside. So keep the lights on for 14-16 hours during the day, and turn them off at night.
Beside this, How long should you keep artificial lights on your seedlings? One convenient thing about artificial lights is that you can set them to turn on and off by themselves using timers. But how long should you keep light on your seedlings? Growers are going to need 12–18 hours of light per day. Your place in that range depends on the costs of two things: real estate and electricity.
In this manner, When should I Turn my grow lights on? The answer to this one is simple. Your grow lights should be turned on (or your seedlings should be put under lights) as soon as the first seed starts to sprout. Many types of seedlings grow very fast, and they will begin reaching for the light as soon as they emerge. So give them plenty of it right from the start.
In this way, How many hours a day should I Light my seedlings?
If they start getting tall or growing sideways, then give them another hour or two of light. Some people like to follow a 12/12 lighting cycle for their seedlings. That means the lights stay on for 12 hours a day, and they are off for 12 hours at night.
Subsequently, Can you put seedlings under grow lights?
The answer is: No, and you should not put seedlings under grow lights for 24 hours a day. Just like us, they need to rest at night. It’s important to follow a normal sunlight pattern, or your seedlings will suffer when it’s time to move them outside. So keep the lights on for 14-16 hours during the day, and turn them off at night.
How long do seedling lights stay on and off?
As a response to this: Some people like to follow a 12/12 lighting cycle for their seedlings. That means the lights stay on for 12 hours a day, and they are off for 12 hours at night. But in my experience, 12 hours is not long enough to keep all types from getting leggy.
When should I Turn my grow lights on?
Answer will be: The answer to this one is simple. Your grow lights should be turned on (or your seedlings should be put under lights) as soon as the first seed starts to sprout. Many types of seedlings grow very fast, and they will begin reaching for the light as soon as they emerge. So give them plenty of it right from the start.
