Welcome aboard, David
! I've heard about fresh water problems in CA so I have to go with Chong on the Well idea. I have eleven 12-14' Blue Javas & almost killed some using a drip system - had to go back to sprayers. And with as many nanners as you have, the Well would probably save ya lots of money in the future.
Anyway, it's a very friendly & info-packed site. If ya have any questions about using the forum, just ask.
Enjoy!
