Description

PRO-MIX® MPO AGTIV REACH® is a multi-purpose growing medium for organic-focused growing, giving professional growers a peat/coir-based potting mix for herbs, vegetables, microgreens, and transplant production. It is built for growers who want one dependable organic growing medium with strong root support, balanced moisture behavior, and broad greenhouse suitability.

This professional growing medium delivers well-balanced air/water properties for consistent crop development. Its physical profile includes medium particle size, medium air porosity, medium-high water holding capacity, and low bulk density, helping create a root-zone environment with space for oxygen movement while holding moisture for steady plant growth. The formulation is suited to a variety of growing applications, including controlled-environment agriculture, greenhouse vegetables, organic crops, and vegetable transplants.

PRO-MIX® MPO AGTIV REACH® includes AGTIV REACH® mycorrhizae technology, the biological active ingredient behind its root-support performance. This mycorrhizal growing medium helps develop and expand the root system, which improves nutrient and water uptake. The result is stronger plant growth, more robust development, and more vigorous, healthy plants in a professional organic production media.

The base blend contains sphagnum peat moss, horticultural-grade coir, perlite, calcitic limestone, and a wetting agent. It also contains a starter fertilizer charge from composted, heat-processed poultry manure and a seaweed-based fertilizer that provides macro and micronutrients. That compact nutrition layer supports early plant needs while the organic growing medium structure supports balanced moisture and air movement.

This product also brings practical production benefits for growers who value consistency. PRO-MIX® beneficial microorganisms are integrated into the growing media, and batch quality checks support reliable product performance. The peat moss used in the blend is connected to Veriflora responsibly managed peatlands, adding a sustainability-focused benefit for growers who consider input sourcing as part of their production decisions.

PRO-MIX® MPO AGTIV REACH® is a good fit for professional growers producing herbs, vegetables, microgreens, greenhouse vegetables, organic crops, or vegetable transplants. It supports root development, nutrient and water uptake, plant vigor, and healthy growth in a versatile peat/coir-based organic growing medium.

Frequently Asked Questions

Why is coconut coir important for plant growth?

Coconut coir is important because it holds water while still keeping roots oxygenated, creating a more stable root zone that supports faster, healthier growth, and it’s unique compared to similar media because it combines soil-like moisture buffering with more controllable, predictable nutrient and drainage behavior.

Why is perlite important for plant growth, and what makes it different from other mix ingredients?

Perlite is important because it increases root-zone oxygen and improves drainage, helping roots stay healthy and active; it’s unique because its main benefit is physical structure and airflow—not nutrients or moisture storage—so it fixes “too wet and compact” root problems in a simple, predictable way.

What does calcitic limestone do for plants?

Calcitic limestone raises overly acidic soil toward a healthier pH range while adding slow, steady calcium for stronger roots and sturdier new growth. It’s important because pH controls nutrient uptake, and it’s unique because it buffers the root zone gradually instead of acting like a fast, temporary calcium boost.

Why do growers use sphagnum peat moss in potting mixes?

Sphagnum peat moss is important because it holds moisture evenly while still supporting air spaces that roots need for oxygen, which makes watering and nutrient uptake more consistent. It is unique because it naturally trends acidic and acts more like a moisture-and-structure foundation than a nutrient source, so it changes root-zone balance in ways other base ingredients do not.

What does a wetting agent do for plants?

A wetting agent helps water spread and soak evenly through the root zone instead of beading up, running off, or channeling through one path, which makes hydration and nutrient flow more consistent. It’s important because it improves the water delivery system rather than feeding the plant directly, making it uniquely useful when the real problem is uneven wetting and dry pockets that can mimic deficiencies.
