It is not a bad batch. **Q: Can you use this for hydroponics? Has anyone tried? thanks** A: It said to use enzymes when using Golden Tree to keep roots Clean? Can you Explain? **Q: Fish Friendly for Aquaponics?** A: See that NPK number on the label? Standard rating for fertilizers. NPK means (Nitrogen, Phosphorous, and Potash (Potassium) This formula is a boost of just POTASSIUM. This would increase the levels of Potassium. Would that affect your fish? I KNOW NOTHING about fish. ## Frequently Bought Together - Humboldts Secret Golden Tree: Best Plant Food for Plants & Trees - All-in-One Concentrated Additive - Vegetables, Flowers, Fruits, Lawns, Roses, Tomatoes & More (16 Ounce) - Humboldts Secret Plant Enzymes – Best Plant and Root Enzymes – 7000 Active Units of Enzyme per Milliliter – Quality Plant Food and Plant Fertilizer – Highly Concentrated – 8 Ounce - Humboldts Secret Sweet & Sticky – Carbohydrate and Saccharide Energy Source – Enhance Aroma and Flavor of Plants – Potting Soil for Indoor Plants – Energy for Plants – 32 Ounces --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/717471378-humboldts-secret-golden-tree-best-plant-food-for-plants-trees](https://www.desertcart.jp/products/717471378-humboldts-secret-golden-tree-best-plant-food-for-plants-trees) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-07*
