Nitrogen atoms in the amino chain are usually bonded to an oxygen atom or two hydrogen atoms, so the nitrogen is not available for the plant to absorb in the nutrient solution. Only the full amino chain is available for absorption. **Q: can this product be used along with Monster Bloom ( Grotek 0-50-30 ) ?** A: No, definitely over kill. Potassium And Phosphorus Are Only Parts Of The Real Story There’s a lot more to fueling bigger flowers than giving your plants correct ratios and types of potassium and phosphorus. It turns out that floral production revs up most when your plants are provided the full range and correct forms of substances called amino acids, which are building blocks of proteins, terpenoids, phenols and alkaloids. This means you want to give 20 “L-form” amino acids to your plants, with especially important doses of L-tryptophan, L-Cysteine, L-Glutamate and L-Glycine. Why the special emphasis on these four L-form amino acids? Here’s the scoop: Your plants utilize L-tryptophan to create an important floral growth hormone called indole acetic acid (IAA). Boosting synthesis of IAA creates larger flowers with more potency. L-Cysteine provides sulphur, and along with L-Glycine is a prime element in formation of an internal plant protectant compound called glutathione. Because many hydroponics nutrients provide no amino acids, and because indoor gardening is inherently stressful to plants, tissue samples show that many plants have glutathione deficiency that slows down metabolic function and results in lower yield sizes. Not only are you now aware of the crucial role amino acids play in floral production and overall plant health, it’s important to have the L-form of amino acids rather than the less-complex “D” form aminos. For one thing, your plants’ cells need all 20 amino acids, but some amino acids are harder for plants to create or absorb. Not only that, but few bloom boosters contain amino acids, and almost all the ones that do contain inferior D-aminos that plants have a hard time utilizing because they are less water soluble. Please remember that only L-form amino acids are the ideal forms for easy absorption and proven yield increase. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***V on April 16, 2026* ### ⭐⭐⭐⭐⭐ Review *by A***R on April 4, 2026* ### ⭐⭐⭐⭐⭐ Review *by C***F on October 6, 2025* ## Frequently Bought Together - Advanced Nutrients GL525050-15 Big Bud Liquid Fertilizer, 4 Liter, Brown/A - Advanced Nutrients Bud Candy Fertilizer, 4L - Xcdiscount B-52 Fertilizantes Booster, 1L --- ## 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.us/products/34945056-gl525050-15-big-bud-liquid-fertilizer-4-liter-brown](https://www.desertcart.us/products/34945056-gl525050-15-big-bud-liquid-fertilizer-4-liter-brown) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-21*
