Need 3rd tent now. Have huge stalks already and exploding with growth. Better than last nutes I used on 1st 2 grow seasons. Love it. ### ⭐⭐⭐⭐⭐ Very good for growth and yield *by K***L on March 27, 2026* Works well only problem being out of stock often ### ⭐⭐⭐⭐⭐ Hugely Successful Grows with Humboldt's Secret *by J***Z on January 20, 2026* I use the whole Humboldt's Secret nutrient line on plants grown indoors in tents with automated lighting, circulation and exhaust fans and manual feeding, watering, temperature and humidity controls. My flowers are cup quality, every time. Top quality nutrients, broad spectrum, easy schedule and dosing and super reasonable compared to other brands with comparable offerings. On average, I'd say my return on investment in yield:nutrient is about 50:1. Hard to argue that. I'm a believer. ## Frequently Bought Together - Humboldts Secret Set of A & B Liquid Hydroponics Fertilizer - World's Best Nutrient System – Hydroponic Nutrients for Outdoor, Indoor Plants – Supports Vegetative and Flowering Stages of Plants - 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 --- ## 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.tn/products/38940154-humboldts-secret-base-a-and-b-liquid-hydroponic-fertilizer-complete](https://www.desertcart.tn/products/38940154-humboldts-secret-base-a-and-b-liquid-hydroponic-fertilizer-complete) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-22*
