I have not used it yet, Will start in the Fall when the weather stabilizes. I bought it based on the reviews by people that had used it already.

Is it ok to spray the hydrograss a rainy day

This worked very well. I used it in an area that gets no sun. Within 3 weeks the area was covered in grass. There's been little rain here in Atlanta, GA, and I failed to water as frequently as the directions indicated, but still the grass came in and looks great.

We did a lot of lawn repairs last year and this product alone works well. We also used it with a lot of grass seeds to protect the other seed from birds and such. We have achieved very impressive results.

This product works perfectly so long as you follow the instructions. I am writing this review 3 weeks after my purchase. All of the patches I filled now have beautifully thick grass. I did use a fertilizer every 7th day on the first watering. The key to growing grass is to keep the ground soft (1in) deep for the germination period

This ACTUALLY works. We saw this as a tv commercial and joked about fixing the spots from our female dog and also from another dog that was digging in the yard. Within a month, the spots were fully grown in. I highly recommend it!

Wow, this is the best. Over the years I have done a lot of grass seeding but this makes it so simple and the results are awesome. It’s very simple just do what the instructions say to do and you will have excellent results this is not rocket science.

It really works especially since I was trying to kill weeds and accidentally bought stuff that even killed my grass, this stuff works I got grass again on all those spots where all the other stores I bought grass seeds didn't work.

This method worked very well for areas in the shade at my house that all the grass had died in. I now have a full lush lawn in that area due to this product! Worked well for me.

Very easy to use instructions. Just attach a garden hose and spray over the intended area. Good idea to spray small patches first to get used to the spray pattern from the attachment. Shipping actually was earlier than projected by the seller which was a pleasant surprise.
