Why do seeds grow better in the dark?

Most seeds germinate underground, so their first stages of growth are naturally in the dark. Seedlings can grow for a certain time in the dark as they have a limited chemical energy store in their cells. Once these energy stores run out, they need light exposure to produce their energy using photosynthesis.

Should cress be grown in the dark?

The cress seeds begin to grow significantly after a day or two and end up being more than 3 times as high. In the dark, the plants have no light to use in photosynthesis. They will therefore put all their energy into growing as high as possible to increase the chances that they may still encounter a ray of sunlight.

Can seeds germinate without sunlight?

Some seeds don’t need light to break through their seed casings and sprout. Most seeds germinate best with controlled amounts of UV generation, but there are seeds that germinate in the absence of light. Furthermore, there are plants that get enough just light in highly shady areas of a garden or even in darkness.

Does more light make plants grow faster?
