I like all the different ways you direct the spray with your fingers--I think I might try those next time I water! I remember watering our
lawn like that before we had spray nozzles, but I never figured out which finger postitions made what type of spray.
I also got rather frustrated with the tiny amount of water that comes out of a nozzle--I realized how little it was when my husband was watering two years ago and I went to fill up my watering can, and it took like 4 times the time than it does to fill it up with a hose. I also don't like the pressure that a nozzle seems to put on my hoses. The joints seem to wear out faster when I use one.
Sometimes I do like to have a gentle way to water my seedlings, though. BUT! I found a better way than using a spray nozzle. Last year all our nozzles had gotten broken by my son. Desperate for a way to make the water fall more gently, I stuck the hose in the watering can, and started watering while holding the hose in the can. It worked wonderfully! The flow from my watering can is nice and thick, while still gentle. It's a little bit more of a strain on my hands to do it this way, but it's worth it because it takes so much less time to water.
