Do Seeds Germinate Better In The Dark? Find Out Here!

Effect of Light on Germination and Seedlings

The most common question asked by new gardeners is whether or not seeds need to be kept in the dark to germinate.

If you want to know if seeds germinate better in the dark we have the answer for you.

The short answer to this question is, “No” – the length of time seeds are kept in the dark has no effect on germination.

Here are the basics about seed germination:  In order to germinate, a seed must have be have the correct temperature, right air temperature, proper conditions, sufficient moisture, proper light requirements, and warmth.

Ambient Temperature and moisture are key factors in germination.  Temperature is less of an issue, since most seeds can survive in between 70-80 degrees Fahrenheit. 

Moisture, on the other hand, is a big issue.  Pot seedling grow best in a humid environment.  If you don’t have a humid environment, try to find an ideal soil temperature that is at least 60% relative humidity.

There are two ways to germinate seeds: in the dark conditions, or in the light. Both methods have their advantages and disadvantages.

Seeds that are to be sown in the natural light will most likely germinate better, since they’re more resistant to stress. They’ll have a higher survival rate and grow faster.

But, if you want to save some time, you can sow them in the dark conditions.

Is Light Necessary for Germination?

There is a lot of debate about whether or not light is necessary for germinating seeds. Some claim that sunlight is essential, while others say that artificial lighting is sufficient. 

To help you decide for yourself, you might want to consider the following:

In general, seed germination requires light, but light isn’t always necessary. In fact, some seeds germinate even when they are kept in the dark , but some seeds require light for germination.

Sunlight is a crucial factor in seed germination requirements, but only a small percentage of seeds are actually photosynthesized. The rest require the presence of light for germination and growth.

This means that it is important to determine the light requirements of seeds, so that we can correctly determine how much growth in daylight of the seeds.

Since 1939, most seed companies have insisted that seeds need sunlight to germinate. But as a recently-published article in Small Times Magazine notes, the science on this is shaky, and there are no hard and fast rules when it comes to seed germination.

Even if you believe that sunlight is necessary for seed germination, it might not be the only way; there are many other methods of getting seeds to grow, including the use of blacklights, microwaves, fluorescent lights and even in a bowl of water.

Seeds That Need Light to Germinate

Some seeds need light to germinate and grow. Others need heat. Exceptions to the rule may include seeds that are light-intolerant seeds, but need light to germinate.

This article will show you examples of seeds that need light to germinate.

  • Cucumber seeds
  • Broccoli seed
  • Tomato seeds
  • Bbean seed
  • Cactus seeds
  • Palm seed
  • Carrot seed
  • Nicotiana seeds

Seeds need light to germinate, but so do seedlings. Thus you want to make sure your seedlings have light so they can grow.

They also have to have some water to drink while they are growing, and they also need food so they can grow bigger.

It needs light for proper seed germination, but in order for them to grow, they must first in a ideal conditions which is into a complete darkness.

This is because many seeds need light to activate the process of photosynthesis. Some seeds need light for 24 hours a day, while others only need to be exposed for a few hours a day.

Seeds That Can Germinate In Darkness

We all know that seeds need light. However, with some seeds, you can grow them indoors in total darkness, so long as they have been previously exposed to light in the day.

The seeds are then transformed by the darkness, and in a few weeks, they grow into something beautiful. 

We’ve compiled a list of seeds that can germinate in complete darkness  

  • Lettuce seed
  • Coriander seeds
  • Chinese cabbage
  • Calendula
  • Gazania

If you don’t like the idea of germinating seeds in the light, there are a few options for growing them at night.

First of all, you can simply cover them in a deeper soil and let them sit there, and some of them will eventually germinate. However, that isn’t the only method.

Some plants, such as the Venus flytrap and coleus can be grown from seeds that are only viable in darkness, usually in a paper bag. This way, you can keep them safe from flies, moths or any other insect that might want to eat them.

How do you know when a seed has germinated?

You can’t wait to plant a seed and see it grow, but it can be hard to tell if it has germinated just by looking at it.

To help you know when your seeds have germinated, here’s a guide on how to recognize the signs of germination.

When you see the seed coat split and a small green sprout emerge from the seed, the seed has germinated.

When a seed emerges from the ground, it’s a big deal. It’s a chance to start a new life, one that takes the seed out of the germination chamber, into the light and into the world.

During this process, the seed is in constant contact with soil. It is covered by a layer of moist earth to keep it hydrated and to prevent drying out.

What happens though, when the seedling is not cut out of this thick root and is pushed aside to an empty area of soil?

The seedling never receives the same attention as the parent. It has no soil to absorb nutrients and water until it’s able to root, and until it’s able to fend for itself.
