I bought this at Home Depot for 20 bucks, expecting it to be similar to the commercial sprayers working on our new subdivision. We saw the commercial sprayers had hydro-seeded the community park with actual, real hydroseed.
I followed the directions religiously. The canister leaks badly, and the garbage that comes out of this thing is cheap, green food coloring that quickly fades to nothing. The canister contains a very small packet of fake green dye, and about 5 cents worth of ryegrass (ryegrass!). After a few seconds, the cheap fake green dye and the nickel's worth of ryegrass are gone and you've been suckered out of 20 bucks plus tax for a complete scam! Shame on Home Depot for selling this garbage. They should be ashamed of themselves. Let's break it down: 5 cents for the fancy looking canister, 5 cents for the tiny sack of fake green dye, and 5 cents for the pitiful little sack of rye seed. Using rye seed is a gimmick. It says "proprietary blend" but if you look at it, it's cheap plain die off early rye. Ryegrass can grow fast but it will die in 6 months.
After I used this product, there was no growth at all, nothing. Not even any residue was left, nothing at all. Horrible scam, and these thieves have probably made a fortune ripping off people one at a time. Way to go Home Depot!
Bottom Line: No, I would not recommend this to a friend
