We have do have some rain gutters, but the house is built into the mountain so they're a foot or so off the ground. I'm sure I can figure out some sort of collection system! As it is, I'm pH balancing the res to 6.5 until the soil isn't so hot (after a few waterings).. then it'll be around 6.2. There's definitely a learning curve coming from hydro to soil/coco mix, as crazy as that sounds... The pH, trying to balance the soils pH and water to hit that perfect number, it's kind of a challenge. As far as a filtration system goes, we already have a lot on the battery bank, I don't know if it could handle another load.. that might have to happen next year.
What can I use to amend the soil to make it more acidic? Organically.. wood ash? Bone meal? I'm wondering if I should just throw something on top and water it down. Same for the fruit trees..
I'm jelly ... you live on a mountain in NorCal and off the grid!
Wood ash is about 20-25% Ca (calcium) so it's not going lower the PH but will do HUGE benefit for your orange clay soil.
Good read on wood ash - I use it ... for sure it works but not for PH. In soil, PH changes all the time. Watering in water that's Alkaline isn't the best. That said.. my outdoor gardens I never worry about it.. there's just way too much soil for water the have an affect on the PH down at the roots. You'd have to add TONS of amendments to change the PH of the soil or even make a minor change.
Good Read - notice it's from a county extension service in Maine. You have one in your county. You can call them and ask about your alkaline water and how the best way to deal with it is. They are there for us ... paid for by us! Take advantage, you'd be surprised. I get soil tests done for 10$ a pop here in the state we live in. That $10.. is golden.

The PH/UP down stuff tho, that's not good for the soil microbes. Something to think about.
Everything in the soil is geared towards growing plants. Water with a slightly alkaline PH I don't think will be a problem. In a container for sure.. but not outdoors, way too much soil to make a dent in the PH. Get local ... there's folks around you that have answers and should be glad to help.
The best thing I would do in a soil grow is inoculate the roots of the plants with Mycos - Mykes brand... Outdoors that's all I do and amend soil with compost. You already have that done...
Hard work is behind you... GREAT job. I'd be your water boy and trimmer if I was closer.
What about a gas powered water pump? Since I'm the new water boy!! Self promoted FTW. Call me Rain Man... wasup wasup wasup!
