Greenleaf Nutrients Multi-Purpose Fertilisers Sea-K-1000g-FBA Editorial Review
The Seaweed and Kelp Fertilizer for Plants, branded as Organic Sea-K, has garnered a positive reception from customers, who appreciate its potency and value for money. As a concentrated extract powder, it offers an efficient way to nourish a variety of plants, making an impressive 700 liters of solution. Users have noted that the fertilizer effectively promotes plant growth, with many seeing significant improvements in their plant pots, particularly for succulents, lithops, and cacti. The compact size of the product, adorned with eye-catching packaging, adds to its appeal; however, the strong odor associated with kelp products may be off-putting for some. Customers have warned to avoid inhaling the dust created during application, as its high concentration means less is more, with several users recommending to use only half of the suggested dosage. Overall, the feedback indicates that the Organic Sea-K fertilizer is well-regarded for its quality and effectiveness. Many users express a strong recommendation for it, citing that it does precisely what it's intended for and enhances the health of their plants. **
