Your germination will vary depending on conditions but the post above is text book germination periods and if water is there are safe figures. I buy turf seed from a golf course supplier in 80# bags wholesale. Runs anywhere between 1.29 lb. all the way to 2-2.25 lb. Annual rye runs about 50 cents lb but is used pretty much only on construction sites. On larger jobs i can get the cost down buying 500# custom blends. This again will vary in cost depending how i mix it.
