How to properly aim sprayers?

They have great coverage, unfortunately a lot of that coverage goes to the floor lol. They come with little stakes, but I'm really struggling to get the angle right, and it's like they were designed to hang down from the ceiling. Plus the stakes are small, and not very secure.

Emitters in bags or pots...yeah lots of overspray. Ive used bubblers in small grows and big pots and ½ inch poly laid over the pots or bags with drip emitters for 3-5 gallon pots.

Yeahhh, I was thinking I might need to switch to drippers. Or maybe I could use larger stakes, and tape them so they face downwards
