Great supplier. - My parcel arrived a little late,but was probably held up at customs as it was sent from the Netherlands.However the backup from Hydroponics Europe was great,and I will certainly be using them again. I purchased some Masterblend fertiliser from them to use on my tomatoes which I grow hydroponically. I have tried different fertilisers in the past,but this is the best. Thanks Hydroponics Europe. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B089T6ZM6T | | Best Sellers Rank | 35,652 in Garden ( See Top 100 in Garden ) 20 in Hydroponic Growing Kits & Systems | | Brand Name | Masterblend | | Country of Origin | Netherlands | | Coverage | leafy vegetables and fruit plants | | Customer Reviews | 4.7 4.7 out of 5 stars (90) | | Item Form | Granules | | Item Weight | 4 Kilograms | | Liquid Volume | 945 Litres | | Manufacturer | Masterblend | | Mixing Ratio | 2:2:1 | | Model Number | 4-18-38 | | Number of Items | 1 | | Part Number | KZm-539 | | Specific Uses For Product | Gardening & Agriculture | | Target Species | Plants | | Unit Count | 4000 gram | ## Product Details - **Brand:** Masterblend - **Item form:** Granules - **Item weight:** 4 Kilograms - **Liquid volume:** 945 Litres - **Specific uses for product:** Gardening & Agriculture ## Images ![4 Kgs Masterblend 4-18-38 Complete Nutrients Hydroponic Fertilizer Kit – Shipping from EU (4) - Image 1](https://m.media-amazon.com/images/I/61Fn89BzV1L.jpg) ![4 Kgs Masterblend 4-18-38 Complete Nutrients Hydroponic Fertilizer Kit – Shipping from EU (4) - Image 2](https://m.media-amazon.com/images/I/81qNdoFJueL.jpg) ![4 Kgs Masterblend 4-18-38 Complete Nutrients Hydroponic Fertilizer Kit – Shipping from EU (4) - Image 3](https://m.media-amazon.com/images/I/71sl6q8opPL.jpg) ![4 Kgs Masterblend 4-18-38 Complete Nutrients Hydroponic Fertilizer Kit – Shipping from EU (4) - Image 4](https://m.media-amazon.com/images/I/713OIQ6tCpL.jpg) ## Available Options This product comes in different **Item Display Weight** options. ## Questions & Answers **Q: this product dosent seem available anymore** A: I hope so I need to order some soon **Q: Can l buy just one packet not three** A: Yes you can also buy the Masterblend 4-18-38 package separately on Amazon! **Q: Do you sell this in 8kg** A: Yes we do but not on Amazon since this size of packaging is not allowed by Amazon (not sure why).
