This makes it very hard to overfeed or burn roots, and it builds long-term soil life over time. The tradeoff: it acts more slowly than mineral feeds, and nutrient levels can vary slightly batch to batch since it's a natural product rather than a lab-blended formula.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003ePremium Organic All-Mix Potting Soil | Heavily Pre-Amended Heavy-Feeder Substrate\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003e​Give your established indoor jungle or high-yielding patio garden the ultimate premium upgrade with All-Mix.
