Hydroseeding will give you superior results compared to the ordinary method of seeding and putting down straw and is a fraction of the price when compared to sod.
Hydroseeding typically begins to come up within 5 to 7 days. If your yard is watered properly you will have a full stand of grass within 2.5 to 3 weeks. If you compare that to the three weeks that seed and straw takes to even begin to sprout then you will quickly see the result, a lush green yard, faster, without burning a hole in your pocket with the excessive expenses associated with sod.
