If you are starting your seedlings indoors, you will need to provide them with the right amount of light and darkness. The amount of light your seedlings need will depend on the type of plant you are growing. Most plants need between 14 and 16 hours of light each day. This can be provided by natural sunlight or by using artificial light.
If you are using natural sunlight, you will need to place your seedlings near a south-facing window. If you are using artificial light, you will need to use a grow light. Grow lights come in a variety of shapes and sizes. You will need to experiment to find the right light for your seedlings.
Your seedlings will also need a period of darkness each day. This is necessary for the plants to perform their natural processes. Most plants need between 8 and 10 hours of darkness each day.
You will need to provide your seedlings with the right amount of light and darkness each day. If you do not, your plants will not grow properly.
seeds that need darkness to germinate
In order to germinate, some seeds need darkness while others need light. It all depends on the plant. For example, the common morning glory (Ipomoea tricolor) produces seeds that need light to germinate, while the castor bean (Ricinus communis) produces seeds that need darkness.
There are two types of dormancy: light dormancy and dark dormancy. Light dormancy is when a seed won’t germinate in the presence of light. Dark dormancy is when a seed won’t germinate in the absence of light.
Light dormancy is common in forest trees. The seeds of forest trees need light to germinate because they have a very thick seed coat. The seed coat protects the embryo from drying out and from predators. The seed coat also contains chemicals that prevent the embryo from germinating. When the seed is exposed to light, the chemicals in the seed coat are broken down and the embryo can start to grow.
Dark dormancy is common in Desert plants. The seeds of Desert plants need darkness to germinate because they have a very thin seed coat. The seed coat does not protect the embryo from drying out or from predators. The seed coat also contains chemicals that prevent the embryo from germinating. When the seed is exposed to darkness, the chemicals in the seed coat are broken down and the embryo can start to grow.
Some seeds need to be scarified before they will germinate. Scarification is when the seed coat is damaged or broken. This can be done by rubbing the seed with sandpaper or by soaking the seed in acid. Scarification allows water and oxygen to reach the embryo, which is necessary for germination to occur.
why do seeds germinate better in the dark
Seeds are the baby plants from which all other plants grow. In order for a seed to become a plant, it must first germinate, or sprout. Once a seed germinates, it breaks through the soil and begins to grow.
There are many factors that affect seed germination, including temperature, moisture, light, and oxygen. One factor that is often overlooked is darkness. While most plants need sunlight to grow, there are some plants that actually prefer to grow in the dark.
One reason why seeds may germinate better in the dark is because darkness is a signal that it is time to start growing. In nature, seeds often germinate in the spring when the days start to get longer. This increase in daylight signals the seed that it is time to start growing.
Another reason why darkness may be beneficial for seed germination is because it helps to keep the temperature and moisture levels constant. Seeds need a certain amount of moisture and warmth to germinate. If the temperature or moisture levels fluctuate too much, it can prevent the seed from germinating.
Darkness can also help to protect seeds from predators. Some animals, such as birds, are attracted to the light and will eat the seeds before they have a chance to germinate. By keeping the seeds in the dark, you can help to ensure that they are not eaten before they have a chance to grow.
If you are having trouble getting your seeds to germinate, try growing them in the dark. You may be surprised at how well they do.
do autoflower seedlings need darkness
Do autoflowering cannabis seedlings need darkness? This is a common question with a simple answer: no, autoflowering cannabis seedlings do not need complete darkness. However, like all cannabis plants, they do need a period of uninterrupted darkness each night in order to thrive.
Autoflowering cannabis strains are unique in that they do not rely on changes in the length of daylight hours to signal when they should begin flowering. This means that they can be grown in a variety of environments, including places where the days are shorter in winter.
However, it is still important to give your autoflowering cannabis seedlings a period of uninterrupted darkness each night. This is because cannabis plants use darkness to produce melatonin, a hormone that helps regulate the plant’s sleep cycle.
If your autoflowering cannabis seedlings do not get a period of uninterrupted darkness, they may not produce enough melatonin, which can disrupt their sleep cycle and cause them to flower prematurely.
To avoid this, make sure that your autoflowering cannabis seedlings get at least 14 hours of darkness each night. You can do this by covering them with a black cloth or placing them in a dark room.
Once your autoflowering cannabis seedlings have been getting 14 hours of darkness each night for at least two weeks, they should be ready to start flowering. If you are not sure whether or not your seedlings are ready to flower, you can check their leaves for signs of stress.
If you see any yellowing or wilting leaves, it is a good idea to give your seedlings a little extra time to mature. Once your autoflowering cannabis seedlings are ready to flower, they will do so regardless of the amount of light they are receiving.
So, if you are wondering “do autoflower seedlings need darkness?”, the answer is no, but they do benefit from a period of uninterrupted darkness each night.
do cannabis seedlings need darkness
Cannabis seedlings need darkness in order to germinate. The process of germination is when the seed starts to grow a root system. In order for the root system to develop, the seed needs to be in contact with water and soil. Once the roots start to grow, the seedling will need light to photosynthesize and produce energy for the plant to grow.
Cannabis seedlings need to be in a dark environment for the first few days after germination. The best way to provide darkness is to put the seedlings in a cupboard or closet. You can also use a grow tent or grow box. If you are using grow lights, make sure to cover the seedlings so they are not exposed to any light.
Once the roots have developed and the seedling has started to grow leaves, it is time to give the plant some light. You can start with a few hours of light per day and gradually increase the amount of light as the plant grows. Make sure to give the plant some darkness at night so it can rest.
do tomato seedlings need darkness
When it comes to tomato seedlings, there is a lot of debate on whether or not they need darkness. Some say that it is essential for the seedlings to get 12 hours of complete darkness in order to grow properly, while others claim that tomato seedlings can do just fine with 6-8 hours of darkness. So, what is the truth?
In order to understand the role of darkness in tomato seedling growth, it is important to first understand how tomato plants grow. Tomato plants are what is known as short-day plants, which means that they require less than 12 hours of light in order to flower. In fact, most tomato plants will only flower when they experience less than 10 hours of light each day.
So, what does this have to do with darkness? Well, when tomato seedlings are first growing, they need a good amount of light in order to develop properly. However, once they reach a certain point in their growth, they actually need less light in order to continue growing. This is where darkness comes in.
By providing your tomato seedlings with 12 hours of darkness each day, you are essentially tricking them into thinking that it is time to flower. This means that they will put all of their energy into growing flowers and fruit, rather than leaves and stems. As a result, you will end up with a much higher yield of tomatoes.
Of course, you don’t have to provide your tomato seedlings with 12 hours of darkness in order to get a good yield. However, it is generally recommended, especially if you want to maximize your tomato harvest.
So, there you have it. Darkness is actually beneficial for tomato seedlings, and can help to increase your yield. Just remember to give them plenty of light during the day so that they can develop properly.
do weed seedlings need darkness
Weed seedlings need darkness in order to germinate. The weed seed must be in complete and utter darkness in order to germinate and break through the soil. If there is even the tiniest bit of light, the weed seed will not germinate.
This is because weed seeds need sunlight in order to photosynthesize and produce food for the plant. However, when the weed seed is first germinating, it has not yet developed the chloroplasts needed for photosynthesis. Therefore, it must rely on the food stored in the seed for energy.
If there is any light, the weed seed will orient itself towards the light in an attempt to photosynthesize. This uses up the food stored in the seed, and the weed seedling will eventually die.
So, if you want your weed seedlings to germinate, make sure they are in complete and utter darkness. Once they have germinated, you can then move them into a well-lit area.
do plants grow better in the dark or light
In general, plants grow better in the light. They need light to produce energy through photosynthesis and to grow towards the light. However, some plants can grow in the dark if they are given enough water and nutrients. These plants usually have white or pale leaves, since they don’t need to produ
