Professional growing media is a horticultural substrate designed for a defined crop, container, irrigation method, and production stage. Peat structure, pH, fertilizer, wetting agent, and added components such as perlite or wood fiber are selected to create the required root-zone conditions.

Estonian peat moss is peat sourced and processed in Estonia for professional horticulture. Estonia is part of the Baltic region, so it can also be described as Baltic peat; a buyer should still confirm the peat type, fraction, moisture condition, packaging, documentation, and intended use rather than relying on origin alone.

White peat is less decomposed and usually provides a more open structure, while black peat is more decomposed, finer, and generally offers stronger water buffering. Brown peat falls between them in decomposition and physical behaviour. A suitable growing medium may use one peat type or a defined combination depending on the crop and production system.

Fine 0-5 mm peat can suit seedling and propagation work where even tray filling and close root contact matter. Broader 0-10, 0-25, and 0-40 mm fractions provide progressively more air space and structure for larger containers, longer cycles, or local substrate recipes.

Raw peat moss is a starting material for substrate producers and local blenders. A finished growing medium is prepared for a defined horticultural use and can include selected peat fractions, pH adjustment, fertilizer, wetting agent, perlite, wood fiber, or other components.

Yes. A local substrate producer can discuss raw peat structure, moisture condition, pH direction, packaging, seasonal volume, required documents, and the components that will be blended locally. The final specification should be confirmed against the local crop and production method.

A seedling or propagation substrate is a fine, uniform growing medium designed for even filling, first wetting, germination, and early root development in trays and plug cells. The right structure, pH, starter nutrition, and wetting behavior depend on the crop and cell size.

Vegetable growers should define the crop, production stage, tray or container size, irrigation water, fertilizer plan, and production period before choosing a substrate. A mix that works for vegetable seedlings may not be suitable for a longer-cycle greenhouse crop.

Blueberry production normally requires an acidic root zone, suitable structure, free drainage, and careful water management. The required fraction and composition change between young plants, larger containers, field planting, and longer production cycles.

Tree and shrub nursery production usually needs a stable structure and reliable water buffering that hold up over longer container cycles. The right peat fraction and composition depend on the species, pot size, irrigation method, and production period.

Mushroom production uses a specialised peat-based casing layer rather than a conventional plant growing mix. The casing material must provide suitable water retention, structure, and consistency for the mushroom production programme.

Perlite is added when a growing medium needs more air space and drainage. The appropriate amount depends on the crop, container, irrigation frequency, and whether the mix is used for propagation, potting, or a longer production cycle.

Wood fiber can increase air space and influence the structure, wetting behavior, and dry-down of a peat-based growing medium. It should be selected as part of a complete composition rather than treated as a generic replacement for peat.

The right pH depends on the crop and on the laboratory method used. Raw peat is naturally acidic, commonly around pH 3.5-4.5; blueberry substrates remain in this acidic range, rhododendron mixes are usually around pH 4.5-5.0, forest nursery products around pH 5.0-5.5, and most vegetable and flower substrates around pH 5.8-6.2 on the RHP scale or within the standard pH 5.5-6.5 range. Calcium carbonate or dolomitic limestone raises the pH; mushroom substrates are commonly adjusted to about pH 6.5-7.5. Compare pH specifications only when the test method and extraction ratio are the same, as H2O, CaCl2, EN, and other methods can give different results.

Some ASB growing media include a defined starter nutrient charge or NPK, while raw peat is supplied without a finished nutrition programme. The selected product specification should state the nutrient level, crop fit, and expected irrigation and fertilizer management.

ASB Greenworld Eesti OÜ has an RHP-certified company profile for professional horticultural substrates. RHP provides an independent quality framework for areas including water uptake, air content, pH, EC, nutrients, and phytosanitary risk control.

Commercial buyers should compare the defined product specification, the documents supplied, and the proposed trial method rather than relying on a product name alone. Consistent structure, moisture condition, packaging, and delivery planning are part of a repeatable supply programme.

Available documents depend on the product and market and can include product information, certificates, brochures, and commercial supply information. The Downloads page shows current public files, while the sales team can confirm additional documents for a specific programme.

Available packaging depends on the product line, but ASB supplies professional bag and bulk formats ranging from smaller bags to large bale formats. The right packaging choice should fit the destination, storage, handling equipment, and planned seasonal volume.

Yes. ASB supports international peat and growing media programmes with defined product specifications, export-oriented packaging, documentation, and sales routing. Buyers should confirm the destination, volume, delivery window, and any market-specific requirements before ordering.

Share the crop or intended use, required structure, product level, packaging preference, volume, destination, delivery period, and document requirements. This allows the sales team to discuss a suitable product and commercial supply plan rather than sending a generic price list.
