Good nutrient for blooms Would buy again ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars This stuff works *by T***T on Reviewed in the United States on March 9, 2024* It maybe early but it seems to make really stout thick flowers. It makes rose buds gigantic when applied right.I can only imagine what it does for other flowers. So far so great. I’m impressed in such a short amount of time that it can do this but it’s hard to tell if it’s this or the cal mag or silica or a combination of all.Good stuff if it doesn’t kill your plants and it doesn’t . ### ⭐⭐⭐⭐ 4.0 out of 5 stars Fertilizer *by D***E on Reviewed in the United States on August 16, 2024* Works as expected. --- ## 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/46146204-humboldts-secretflower-stacker-best-flowering-formula-for-bigger-harvests-flowering](https://www.desertcart.tn/products/46146204-humboldts-secretflower-stacker-best-flowering-formula-for-bigger-harvests-flowering) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-21*
