This was totally Not the product that was sent .. the picture Is of old original not the new one ( same Name only the numbers were differnt when the bottle arrived ) warning ! This one can cause Nitro toxicity with come nutrients at The start of week I called Amazon they said it was the 3rd party sellers fault on picture , they Interim blamed Amazon . I have given up on any type of explanation . Even called Oregon the main supplier . Nothing . Because I have used part of this bottle it seems to void it all. To bad because the old Version is the best ever ... And trying to get my hands in the old one seems impossible. ## Frequently Bought Together - Power Si (1 Liter) - House and Garden "Gold" Root Excelurator 1 Liter - Mad Farmer Mother of All Bloom 10lb (4540g) (1/Cs) --- ## 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.be/products/260135831-1-liter](https://www.desertcart.be/products/260135831-1-liter) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-17*
