What happens to a seedling if it does not get light?
Without light, the seedlings die under normoxic conditions within a certain time window. In absence of oxygen, however, they survive much longer. Maybe seedlings wait for rain and wind to strip off the last layer of soil.
Will seeds germinate without light?
All seeds can begin without sunlight because of the energy stored within them. All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate.
Why is light important in seed germination?
However, some seeds germinate best in absolute darkness, and others perform well with continuous sunlight. Light does become vital for every species after germination, because the initial sprout will not survive if it cannot reach a light source.
Why do some seeds don’t need light to germinate?
So, a seed on the soil surface gets enough light to keep the dark form of phytochrome low for sufficient time to prevent germination initiation. It is only when the seed is in permanent darkness that the dark form of phytochrome is active for long enough to trigger germination.
How close should my light be to my seedlings?
about 2 – 4 inches
Are LED lights good for seedlings?
LED Grow Lights for Seedlings LEDs are a great option for grow lights. They are a bit more energy efficient than fluorescent and there’s a lot of options out there. You’ll find two main types: free-standing and a traditional hanging light.
Can you start seeds with LED lights?
Summary. You can use LED lights to start your vegetable seeds indoors and you don’t need special plant grow lights to do so for plants that will eventually be planted outside. If you have a lot of fixtures you can rewire them a few at a time while still gaining the benefits of LED bulbs in all your fixtures.
What is the best light for starting seeds?
A: Stick with ordinary fluorescent lights. They are readily available, reasonably priced, and work well for seedlings. Combining a “warm” white tube with a “cool” white in the same fixture will give the same results as a pair of special “grow lights.” The best are probably 4-foot-long shop lights.
Can a normal LED light be used to grow plants?

Can you start seeds in egg cartons?

Should I soak seeds before planting?
It is recommended that you only soak most seeds for 12 to 24 hours and no more than 48 hours. After soaking your seeds, they can be planted as directed. The benefit of soaking seeds before planting is that your germination time will be reduced, which means you can have happy, growing plants faster.
