I set the heat mat at 80 degreess and left the light on 24hrs.
Two days later the seeds were sprouting!
At the end of the week on April 7th I pricked out the zinnias to egg cartons. I think that transplanting them from the egg cartons to the garden will cause less transplant shock. I'd heard that Zinnias don't like to have their roots disturbed and grow better if they are direct seeded. But here again they wouldn't stand a chance because of the earwigs. I think zinnias are related to sunflowers and earwigs love them both. So I am testing the egg carton planters for this purpose.
Out of 50 seeds I have 40 seedlings.
