The 5 L container is sized for that, and it has the lowest price per litre of the three sizes.\u003c\/p\u003e\u003ch3\u003eWhat's in it\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eMatrix Bloom\u003c\/strong\u003e from Fenix MTX (Germany) is a PK additive for the \u003cstrong\u003elast 4 weeks\u003c\/strong\u003e of flower. German retailers list it as \u003cstrong\u003ePK 18\/23\u003c\/strong\u003e (18.46% phosphorus, 23.40% potassium), a stronger mix than a classic PK 13\/14. According to the manufacturer it helps flowers and fruits harden and fill out, and firmer cell walls let fruits hold water and keep longer.\u003c\/p\u003e\u003ch3\u003eScale: up to 10,000 L\u003c\/h3\u003e\u003cp\u003eRetailers give a dose of 5–10 ml per 10 L of water (0.5–1 ml\/L); Fenix MTX itself refers to its feeding schedule.

For a 300 L tank that's 150–300 ml per fill.\u003c\/p\u003e\u003ch3\u003eDosing pump and storage\u003c\/h3\u003e\u003cp\u003eWith tanks this big, a dosing pump or a dedicated measuring jug keeps the PK level identical from batch to batch. Shake the container before drawing from it and decant a litre for daily use so the bulk stays sealed. Check EC after every mix: a high-PK additive pushes it up quickly. Store dark and frost-free between runs.\u003c\/p\u003e","brand":"Matrix MTX","offers":[{"title":"Default Title","offer_id":58744113103192,"sku":"C8MTX01071","price":119.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/9584\/8792\/files\/c6347453643dd5c33bbf5466e97761c2_1c163fea-507a-43db-8f89-501fe1c0831e.png?v=1791813355","url":"https:\/\/growdealz.com\/products\/matrix-bloom-5-l","provider":"Growdealz","version":"1.0","type":"link"}
