Quick and rewarding purchase!
A terrific product. It quickly filled in bald spot in my yard...grass came in lush and green. I liked it so much that I bought it again for other areas in my yard that I had no intention of working on!

Works surprisingly well so far
I live in NJ and bought this mid September. Used it on several dead patches and in less than 2 weeks the bare patches (maybe a foot or so in diameter) are gone, and a few days later used it on a much larger section that sod wouldn't take and some expensive smart grass seed blend didn't as well which was a waste of money. This fast growing seed about a week out from seeding already has maybe 2" grass seedlings shooting up. I will have to do some fill ins but i still have plenty of seed to fill that all in. This works really well so far, we'll see how it holds up over winter and the summer weather. Going to add some fall fertilizer this weekend.

Best grass seed I ever used!!! See pic’s
This grass seed is awesome! Loosened the dirt with a star gadget. Spread the seed and watered. It was one inch high in 7 days. We even had the temperature go down to 32 F one needs night. I planted on Sunday and I'm looking at it one week later and it is one inch high.

I live in utah, it’s dry and hot
Didn’t grow out here in utah, it was middle of summer too so maybe the heat didn’t allow it to grow

This is good grass-man!
Sprouted fairly quickly and gave good coverage. Seems hardy doesn’t need tons of water.

Fast growth
The week after planting I could witness a beautiful and green lawn. It grows pretty fast, about 7-9 days if you water it every day. Also weather should be warm and noons should step on the grass first 2-3 weeks.
