This is because commercially produced seeds are grown and selected for their easy germination as well as other obvious characteristics, so specifics such as light or dark requirements don't often occur. As much as it may surprise or shock you, it's important to know that most seeds germinate best when placed in the dark. Do not confuse seeding requirements with what seedlings need. Germinating seeds at room temperature or a little warmer is sufficient for most seeds, and some gardeners use a temperature-controlled seedling heating mat when they need extra warmth.
Can seeds germinate without light?
And remember that seeds have been sprouting for thousands of years without much effort — it's just nice to give them the best chance possible by providing them with optimal conditions for them to thrive. For seeds that are sown directly outdoors, another option is to cover the seeds with a thin layer of fine vermiculite, a naturally occurring mineral with water-retaining properties. It can usually be found near seed. Pay attention to finely ground vermiculite for horticulture, as other species are not suitable for gardening. Without enough oxygen, seeds can't balance enough water and carbon dioxide to generate the energy needed to grow.
Do I need a light to start seeds indoors?
seeds that need light to germinate, make sure the seeds are in contact with the seed's starting medium but are not covered. It is very important that you get the right lighting for seedlings and NOT all bulbs are the same. Although some plants may go outside earlier (see seed package), most should stay indoors until the last frost date for your area has passed and your soil has warmed up. In addition to starting seedlings and herbs, artificial lights can also be used to grow many vegetables indoors.
Or, for a more economical solution, purchase large fluorescent lamps equipped with a warm bulb and a cool bulb.
