Hunter PGP too long for 25'?

Based on the charts PGP is not optimal for these distances. If I use the smallest nozzle the GPM would be too low. Is that correct? My pressure is about 30-35 PSI.

is your pressure 30-35 static or dynamic?

Based on the charts If your zone is designed properly- They will throw about 30'

Smaller nozzle gpm just means longer run time... It's actually a good thing to have

Reading your other posts and that you are starting up your own system.

My personal recommendation of rotors are the Rain Bird 5004 +

In my opinion these heads are far superior then pgp's. With using your difuser, flow control ( at the head) and low angle's ( if need be) you can get this head to water almost any area

Thanks for reply Mitchgo. I didn't check 5004 yet but aren't they the same range as PGPs? As far as using smaller nozzles I read recommendations not to use less than 2 GPM nozzles since little wind blow away water. Then again I'm no professional just reading and open to suggestions.

the pgp and 5000 are essential the same, though the 5000 has the ability to control flow and actually turn off the rotor. The pgp doesn't ( though the hunter i20 does)

It's true wind will push the water. It's recommended to water early morning where in most places in the world- the wind is the least in the morning. However, if designed properly wind shouldn't be a huge deal . Or design it to compensate for a constant wind application.

2gpm a nozzle is fine. I generally don't go lower then 2

Have you consideredMPR Rotator nozzles?

Not really. I read their reviews seems a little finicky. I think I will be going with Hunter PGJ or Rainbird 3500.
