Sure. Well, in simple easy terms, the letter (n) designates the year the seed is planted and a seedling begins. That first year growing cycle becomes year (n). The second growing season, or the year following, becomes (n + 1). So, as an example, a seedling sprouted in spring of 2013, would be identified as (n + 1) in 2014. And (n + 2) in 2015, (n +3) in 2016 and so on. Another example: the seedlings I sprout this coming spring, 2014, will go through 2 full growing seasons (this coming summer and the next) and transplanted in the garden in the fall of 2015. Those will be (n + 1) when I transplant them.
