I have a bubbleponics set up for germinating seeds. Seeds will go into Rock wool cubes that I will transfer to soil (organic). I want to use the same water I am using for watering once they transfer to soil. It would be from a fast moving creek that goes through the back yard. The pH is in the high 7 to low 8...I would adjust down. Does anyone use rainwater/freshwater in a hydro system? The Ppm is around 200ish higher levels of iron in the area. I won't be adding any nutrients...maybe an organic tea once the plants get a bit more established before they go into the soil.
