…and soil to germinate, but do they also require light?
This is an issue that many gardeners may be considering.
Like how Patrick did.
People had been experimenting with seeds on the internet and I admit I have a bit of FOMO.
I, with the help of my girlfriend, started shopping for tools to make our own small garden.
We’ve bought several seeds we’re interested in growing out, pots, watering cans, then there’s a question in both of our minds:
Should we have lights for the seedlings?
Because if yes, we’ll have to buy one as our apartment doesn’t have good lighting for plants.
If you are asking the same question, you have come into the right place!
We also have an article on this blog about the best grow light on Amazon that you might find interesting.
What is Germination?
Is it necessary for the seed to germinate in the presence of light?
What does it take to cultivate a seed? Seeds require the sun, water…
…and soil to germinate, but do they also require light?
This is an issue that many gardeners may be considering.
Phase – Imbibition
Before sowing, immerse the seeds in warm water overnight.
The seed coat will enlarge and soften as a result, making it…
…easier for the seed to germinate. This can also be aided by…
…wrapping the seeds in moist paper towels and placing them…
…inside a plastic sheet.
Scarification may be required in some cases to persuade hesitant…
…seeds to participate in the treatment.
Phase – Interim lag
Before seeds germinate, they must be viable.
The term “viable” refers to the seed’s ability to grow due…
…to the amount of energy contained within it. Nutrients and…
…water are stored in dormant seeds. When it’s time for the seed…
…to germinate, the correct conditions must be present.
When a seed is exposed to light and oxygen, it germinates.
Radicle and Root Emergence Phase
To complete the sprouting process, cells within the seed expand and divide…
…to form the primary root or radicle.
The seedling will emerge from the earth thanks to the radicle, which will…
…subsequently bind the structure to the ground while absorbing moisture.
This process differs depending on whether the seedlings need to lift their…
…cotyledons (seed leaves) above the earth (epigeous) or need to keep them…
…comfortably below the ground (non-epigeous) (hypogeous).
Seedlings burst through the earth’s surface at this point and begin to mature into adults.
Do Seed Need Light To Germinate
Following the planting of seeds in a seedling tray, the next step…
…may appear obvious:
Isn’t it true that they require light in addition to warmth? In reality…
…some seeds require darkness rather than light to germinate.
When the seeds mature, they should be placed in direct sunlight.
You don’t have to aim to be a master gardener, but you can become…
…the master of your own garden, if you take the time to learn how to…
…nurture seeds through their most difficult stage.
Tips
The majority of seeds germinate best when stored in the dark.
Light, which is required for seedling growth, may actually hinder…
…the germination process.
Most seeds thrive in the dark
It’s easy to forget that seeds are living beings, so fussy might be…
…an understatement. Behind the thick shell are an embryo and food.
While your seeds may appear to be viable on the surface, they will…
…only sprout if the conditions are favorable or if they are exposed to the…
…suitable temperature as well as the necessary amount of air, moisture, and light.
Soak your seeds well.
When you open the package and inspect the seeds to ensure they are intact…
…your pulse rate may quicken. Any seeds that appear to be damaged…
…should be discarded since the seed embryo may be destroyed as well.
Then, if you can hold your excitement and wait a day before planting the seeds…
…soak the seeds overnight.
This technique weakens the seed covering, making germination easier.
Recognize the Seeds That Require Light to Germinate
There will almost definitely be numerous parallels in seed requirements.
To grow, they usually require the appropriate number of seeds per cube.
According to Tower Garden, this often means one or two seeds…
…for vegetables, up to six seeds for herbs, and six to twelve seeds for lettuce…
…and other greens. Seeds also require three times their thickness in burrowing…
…depth, damp, cold, and finely textured seedling soil, and an indoor…
…temperature of 60 to 70 degrees Fahrenheit.
Still, All Seedlings Need Light
“Gardeners are most likely to make one of three common mistakes: an insufficient amount of light, lights that are placed too far away from the seedlings, or lights that aren’t left on long enough.”
Upstart University
After they sprout, it’s time to shift gears. Your seeds did not require light to germinate…
…but the seedling will. Even yet, simply setting the tray on a sunny windowsill is unlikely…
…to produce the constant growth you seek. Seedlings that grow slowly at first and then…
…become tall and lanky are telltale signs that they aren’t getting enough light.
This is why many seasoned gardeners recommend using grow lights.
LED or fluorescent lights, when used properly, can be a terrific solution.
At this stage in the growing process, gardeners are most likely to commit…
…one of three common mistakes. Fortunately, these problems are easy to resolve.
LED bars should be 8 to 10 inches apart, and fluorescents should be 4 to 5 inches…
…apart for the best coverage and lighting. The term “coverage” refers to making sure…
…that the lights illuminate the entire seedling tray. In terms of lighting, place LED lights…
…8 to 12 inches above the tops of the seedlings and fluorescent lights 5 to 6 inches over…
…the tops of the seedlings. Every day, the average seedling requires 14 to 16 hours of sunshine.
It may be a challenging schedule to adhere to, which is why many gardeners prefer to use a timer…
…to manage their grow lights.
Light’s Important for Seedlings’ Strength
Gardening isn’t an exact science, but mastering the critical problem of light…
…may do wonders for your confidence and seedlings. After rushing over…
…to inspect your seedling tray, you may be presented with something you…
…don’t understand. Fortunately, many flaws can still be fixed at this time.
Consider the sudden appearance of overdeveloped or crowded seedlings.
Thin out the tray now is an ideal time to assign one seedling to each cube.
Become Busy Gardening experts advise you to act fast if you observe leaves…
…turning yellow, brown, or white, or that appear dull in comparison to the others.
Sum Up
To answer the question: do seed need light to germinate?
Light is not required for all seeds to germinate. Some seeds can grow in the dark…
…while others require a lot of light to flourish. All seedlings, however, require light.
At the very least, to provide them with stability as they mature. This increases your…
…chances of successfully growing the seeds. If you find it difficult to prepare for everything…
…Amazon sells a seed growing kit to help you get started.
