Review: Plants are happy - I stumbled upon Down to Earth OMRI Organic Solution Grade Langbeinite while searching for an organic potassium source for my plants, and I'm so glad I did. This stuff is a game-changer. First off, it's OMRI certified, so I can trust that it's truly organic and safe for my plants. Plus, it's easy to use. I simply mix it into the soil or dissolve it in water, and my plants soak up all that potassium goodness. But let's talk results. My plants have never looked better. They're healthier, greener, and producing bigger, more vibrant blooms than ever before. And because it's slow-release, I don't have to worry about overdoing it. It provides a steady, consistent source of potassium over time, which is exactly what my plants need for long-term health and vitality. Overall, I couldn't be happier with Down to Earth Langbeinite. It's reliable, effective, and organic – everything I look for in a fertilizer. If you're serious about giving your plants the nutrients they need to thrive, give this stuff a try. You won't be disappointed. Review: Great plant food - This has been feeding my weed plants very well. It has no smell and it was affordable. You only need about 1 tbsp per feeding (depending on where you’re at in the grow) so the bag will last a very long time. ## Features - Triple Nutrient Formula (0-0-21.5): Supplies 21.5% potassium, 10.8% magnesium, and 22% sulfur to boost crop health and performance. - OMRI Listed & Organic: Approved for use in certified organic growing systems and safe for edible crops. - Chloride-Free: Gentle on plants and beneficial soil microbes, making it ideal for sensitive species and soils. - Solution Grade Powder: Finely milled and water-soluble for easy use in foliar sprays, hydroponics, and fertigation systems. - Supports Flowering & Fruiting: Enhances nutrient uptake, improves flavor, and increases resilience to stress. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07SRW44HT | | Best Sellers Rank | #121,339 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #2,344 in Garden Fertilizers | | Brand | Down To Earth All Natural Fertilizers | | Brand Name | Down To Earth All Natural Fertilizers | | Coverage | 200 | | Customer Reviews | 4.5 out of 5 stars 132 Reviews | | Item Form | Powder | | Item Weight | 16 ounces | | Liquid Volume | 16 Fluid Ounces | | Manufacturer | Down To Earth All Natural Fertilizers | | Model Number | DTE-FERT-SOLU-Langbeinite-1lb-FOS | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | DTE-FERT-SOLU-Langbeinite-1lb-FOS | | Specific Uses For Product | Plant Growth | | Target Species | Plant | | UPC | 714360190225 | | Unit Count | 16 Fluid Ounces | ## Product Details - **Brand:** Down To Earth All Natural Fertilizers - **Item Form:** Powder - **Item Weight:** 1 Pounds - **Liquid Volume:** 16 Fluid Ounces - **Specific Uses For Product:** Plant Growth ## Images ![Down To Earth All Natural Fertilizers Organic Solution Grade Langbeinite - Professional Grade Potassium Magnesium Sulfate Powder 200 mesh for Liquid or Spray 0-0-21.5, 1 lb - Image 1](https://m.media-amazon.com/images/I/71RRN9lWQAL.jpg) ![Down To Earth All Natural Fertilizers Organic Solution Grade Langbeinite - Professional Grade Potassium Magnesium Sulfate Powder 200 mesh for Liquid or Spray 0-0-21.5, 1 lb - Image 2](https://m.media-amazon.com/images/I/71ItzzadlNL.jpg) ![Down To Earth All Natural Fertilizers Organic Solution Grade Langbeinite - Professional Grade Potassium Magnesium Sulfate Powder 200 mesh for Liquid or Spray 0-0-21.5, 1 lb - Image 3](https://m.media-amazon.com/images/I/91f+GQY6JrL.jpg) ![Down To Earth All Natural Fertilizers Organic Solution Grade Langbeinite - Professional Grade Potassium Magnesium Sulfate Powder 200 mesh for Liquid or Spray 0-0-21.5, 1 lb - Image 4](https://m.media-amazon.com/images/I/71N4Saj+frL.jpg) ![Down To Earth All Natural Fertilizers Organic Solution Grade Langbeinite - Professional Grade Potassium Magnesium Sulfate Powder 200 mesh for Liquid or Spray 0-0-21.5, 1 lb - Image 5](https://m.media-amazon.com/images/I/918ZYTvH-GL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Plants are happy *by M***. on March 17, 2024* I stumbled upon Down to Earth OMRI Organic Solution Grade Langbeinite while searching for an organic potassium source for my plants, and I'm so glad I did.
