Can seeds germinate without light?
Can seeds germinate without light?
First, true enough, light isn’t necessary to germinate most seeds: the majority are perfectly capable of germinating in complete darkness. But there is a significant proportion of seeds that will not germinate if they aren’t exposed to light. This includes maybe a third of the plants we commonly grow from seed.
Do seeds need light or heat to germinate?
Most seeds do not need light to germinate, so covering the planted containers, placing them on the heat source, and checking them daily (watering when necessary), can work well for germination. When the seeds begin to germinate, remove them and place them directly under a light source.
Do you need grow lights to start seeds?
How Much Warmth Do Seeds Need? Seed-starting happens in two stages: germination and growing. Germination is the sprouting stage, when the root and leaves emerge from the seed. You won’t need light at this stage because it occurs under the soil, but you will need gentle warmth (not harsh heat).

What month do you start seeds indoors?
The best time to start seeds is usually late March to late May. Only the southern zones are suitable for starting plants from seed in the earlier months. Give the plant enough time to germinate and grow to an appropriate transplant size.
Can you use plastic egg cartons to start seeds?
You can use any plastic egg carton to make this planter. After finding your carton, gather a sterile, light weight, fine particle soil mix to improve your chances of success. I use a pre-mixed seed starting mix to make things easy. You can also mix your own with a mixture of peat, perlite and/or sand.
Do you need light for seeds to grow?
So with this information, how would we answer our question “Do seeds need light to grow?” We learned that the answer was a qualified yes. It appears that seeds begin to sprout regardless of whether they are exposed to light or not. But seeds need light in order to form leaves. Experiment: What temperature do seeds like?
Why do some plants need light to sprout?
Very often it is seeds that self-sow that require light. These plants, such as balloon flower(Platycodon grandiflorus) and poppies, drop their seeds on the soil and they germinate where they land. They sprout in response to environmental factors, including having the light hit them.
Do you need sunlight for sprouts to grow?
However, a bit of sunlights will be needed for sprouts with green leaves to perform photosynthesis in order to produce chlorophyll for greening. On the day of harvest, expose your sprouts to light for 15 minutes and watch the magic.
What to do with seedlings before they sprout?
If the seeds are tiny enough that they are likely to blow away, you can sow them on the surface of the soil, sift a fine layer of compost over the top and water the compost. Doing so will hold the seeds in place while allowing light to penetrate.
