I am about half way through the seed germination experiment. Already trends are appearing in the data. So far, I've germinated seeds at three temperatures: 75, 65 and 55. On really hot days I want to crawl into the growth chambers and hang out with a book until it's cooler. Hopefully there won't be many more hot days this year.
The maximum number of seeds at each temperature is 50. So, for defender lettuce at 75 degrees all the seeds germinated by the third day. As the temperature decreased it took longer for seeds to germinate, and germination was spread over a number of days. This is useful because it tells a grower or farmer that they don't need to heat their greenhouse all the way to 75 or 65 degrees to have good germination of lettuce seeds.
