With 20 psi and assuming you have some fairly long rows, I'd look into a drip (tape)system. Soaker hoses are expensive compared to drip tapes and do a poor job applying the water uniformly. The big advantage of soaker hoses is that they are very simple to lay out and start using. Drip systems would require a newcomer to learn some things before being able to set up and use them properly. It is well worth the time to learn how to use drip systems especially if you have expensive water.

Hi Stt60,

Good call Michael357, especially with a 1-1.5% spent downward along the row. If you row irrigated before the tape would be just right. It isn't hard and there is plenty of help and information available. GL and Aloha.

I would agree also. You would also get more water closer to the point of connection and less the further you get.

Ditto to all the posts. I found a good quality and reasonably priced source: Drip Works. Google it, they send free catalogs.
