there is a conifer forum.. where there have recently been many post on growing seeds .. as well as sight-line/windbreak posts ... come check it out ...

though starting seed would be a fun experiment.. can i suggest you buy some bulk 2 year old seedlings.. and get those growing.. while you find out if starting your own seedlings is a viable option ...

also contact your county soil conservation or extension office.. and find out if they have a spring seedling sale... and if you still might get involved with that ...

welcome to the GW ...

good luck

Here is a link that might be useful: link

Surely the most common question on this particular forum.

A search will reveal dozens of threads on whatever species you choose (should do more than one), with much discussion on attributes and issues.

Do you want all one species? A disease that targets that species could wipe out your screen. I'm not familiar with your climate; if I were doing something like this elsewhere, for example, while I might use a lot of green giant arborvitae, I might also use a few Colorado blue spruce, a few golden hinoki, that sort of thing. Diversify my species and also get some blues and yellows in there. Your main 'back bone' tree need be cheap, but a few pricier options here and there can help.
