My tap water is 6.8 to 7 so I have to PH down. I use Phosphoric acid. Because of this I use a rez (and blumats). But I don't like the heat issues especially in summer, the faff and work required, the crazy amounts of acid needed.
I'd love to water straight from a hose, highly oxygenated cool water. I was thinking of pipeting/injecting acid into the hose flow into the trays the plants stand in.
Then lately I've been thinking of a much more simple method, a layer of peat (4-5ph) on top of the coco might be enough to counter the higher PH tap water, getting rid of my need for reservoirs and acid altogether.
Also some nice amendments can be added to the peat to increase the micro herd and hence PH modifying abilities while still having mainly coco as the substrate and it's benefits - Anyone had similar thoughts/experiments?....I might just try it!
