water it just enough to get it wet looking every hour

need to water deeply - the seed is at the surface. You just need to
make sure it doesn't dry out until the seed is sprouted. If you can't
water that often, you will need to water harder, but don't overdo it.

This is good advice. I said "lots of water". That is NOT to be meant to soak
it heavily each time. As you said, that will wash away the seed. Over time,
it will take a "lot of water", but applied a little at-a-time.
