{"product_id":"sustrato-de-germinacion","title":"Germination substrate","description":"\u003cp\u003eAchieving uniform germination and vigorous seedlings in professional propagation requires a substrate with fine structure, low salinity, and adjusted pH, capable of retaining moisture without compacting. This germination substrate —also called \u003cstrong\u003eseedling substrate\u003c\/strong\u003e, propagation peat, or seedling mix— is manufactured with first-selection Baltic peat, with H3-H6 humification controlled in our own laboratory, and designed for professional nurseries, automated seedling lines, cuttings, and propagation of horticultural and ornamental crops in the Dominican climate.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFine, uniform structure:\u003c\/strong\u003e sifted fraction that favors intimate seed-substrate contact, even germination, and root development without physical barriers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePremium raw material:\u003c\/strong\u003e Baltic peat selected at origin, free of weed seeds, pathogens, and impurities.

This peat is selected at origin by H3-H6 humification grade, sifted into a uniform fine fraction, and enriched with dolomitic limestone and wetting additives through production processes controlled in our own laboratory. That careful manufacturing chain is what separates a professional substrate from anonymous seedling soil that ruins expensive seeds.\u003c\/p\u003e\n\n\u003ch3\u003eFactory specification\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eModel SF1 (Standard Suliflor line).\u003c\/strong\u003e Substrate made from dark Baltic peat extracted from raised bogs, with H3–H7 humification on the von Post scale, formulated at the factory as \u003cstrong\u003eslow-drying\u003c\/strong\u003e peat — the key characteristic that positions it as a reference in warm climates where a light peat would dehydrate between waterings. Under Caribbean conditions water evaporates more slowly, seedlings undergo less water stress, roots develop with stable moisture, and the propagation operator gains margin in irrigation frequency. Dark peats also deliver a higher concentration of humic acids that stimulate rooting, and superior buffering against occasional spikes of fertilizer in the irrigation water.
