Do you germinate seeds in dark or light?
Most seeds germinate best under dark conditions and might even be inhibited by light (e.g., Phacelia and Allium spp.). However, some species (e.g., Begonia, Primula, Coleus) need light to germinate (Miles and Brown 2007). Don’t confuse seed light requirements with what seedlings need. All seedlings require sunlight.
Do cucumber seedlings need light?
Whether you use an artificial grow light or the good old-fashioned sun, make sure your cucumber seedlings are getting between six and eight hours of light each day. Although they can grow with only four or five hours a day, you’re more likely to see stunted or slowed growth.
Why won’t my cucumber seeds germinate?

Why do seeds germinate better in the dark?
The presence of light tends to inhibit their growth. The light decomposes carbonic acid gas and expels oxygen which leads the seed to harden. These gases are key factors that promote germination. In dark environments, the gases remain undisturbed and germination is favoured.

How do you speed up seed germination?
One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don’t soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.
