That depends very much on how they have been stored. In sealed,dry and cool conditions they can last up to ten years, but this is reduced to two years if these conditions have been different. These times can vary according to variety, and sweet corn seeds do not last as long as the popcorn, dent and similar types.
If kept tightly sealed and refrigerated it will keep for a long time, probably at least 6 months. If not refrigerated (but well sealed) it should be fine for a month or two. If it is clear and does not smell rancid, it is probably fine (assuming it is less than 6 months old) . Oil exposed to air will turn rancid rapidly - in a few days or less. In any case, it should at least be kept in a cool, dark, place. (Refrigerated oil may appear cloudy until warmed up - that's OK. I started refrigerating mine a year or two, and it has dramatically extended the lifetime of the oil as described.)
2 days to 3 days to germinate the corn seeds
seven to ten days,
2 to 3 weeks.
takes 6 mouth
2-3 years
It depends on what type of corn you want to grow...
It tales about 3-6 weeks to grow into a big corn plant.
the seed will likely germinate in 12 days
10 years
probably a week or two
6 WEEKS
It takes a been seed 6 to 10 days to grow
it depends on the seed, but i think most take about a day.
About 14 days if conditions are right.
about a week or two.
It takes Marigolds 17.5 min. to grow from a seed to the finished product.
You will be waiting for an eternity, because any plant will not grow in a dark place. Plants, including corn, need sunlight to grow. They will not grow if they are not exposed to sunlight.
