Many soils dump a cloud of ammonia at start-up. Without a supportive bed, roots stall, tannins keep the water yellow, and parameters swing.\u003c\/p\u003e\n\u003cp\u003eMade in Japan with multi-stage surface sintering, it buffers toward soft tropical water and holds humic and fulvic acids in the granule.
