PRO-MIX® CCX AGTIV® REACH™ Growing Medium — 17 lb (50L) Loose Fill | 100% Coco Coir | OMRI Listed®

PRO-MIX CCX AGTIV REACH Growing Medium - 17 lb (50L) Loose Fill - 100% Coco Coir - OMRI Listed

PRO-MIX CCX AGTIV REACH is a 100% coco coir substrate blending coco fiber and husk chips, formulated for growers who want peat out of the equation entirely. The fiber component holds moisture while the husk chips create air-filled pore space, giving the mix 70-75% water retention alongside genuine aeration rather than a soggy, compacted root zone.

It's OMRI Listed, so certified organic operations can use it without a compliance question mark, and it carries the same AGTIV REACH mycorrhizae found across Premier Tech's peat-based lines. The 17 lb (50L) loose fill bag is ready to use with no rehydration step, which matters for coco products that sometimes ship compressed and need soaking before they're workable.

Key Features & Benefits

• 100% coco fiber and husk chip blend — combines fine fiber for moisture retention with coarser husk chips for air-filled porosity, avoiding the all-or-nothing tradeoff of a single coco particle size.
• 70-75% water retention — holds enough moisture to reduce irrigation frequency while the husk-chip fraction keeps the root zone from staying waterlogged.
• OMRI Listed — certified for use in organic production under USDA NOP and equivalent standards, so certified growers can use it without a separate compliance check.
• AGTIV REACH mycorrhizae — inoculates roots to extend effective nutrient and water uptake, the same mycorrhizal technology used across Premier Tech's peat-based PRO-MIX lines.
• Renewable coco by-product — coco coir is a by-product of coconut processing rather than a harvested peat bog, which growers moving away from peat often weigh as a sourcing consideration.

Who Should Use This

CCX suits high-value crop producers, certified organic growers, and controlled-environment agriculture operators who want a consistent, renewable coco substrate, particularly those running drip, recirculating, or automated fertigation systems where a predictable water-retention curve matters for repeatable results.

About PRO-MIX

PRO-MIX comes from Premier Tech. The company has sold peat substrate since 1923. It introduced PRO-MIX in 1968. Premier Tech runs its own peat bogs. It also runs its own processing plants. Its distribution reaches North America and beyond. The company runs a biotechnology lab too. That's where AGTIV mycorrhizal inoculants get made. Premier Tech controls its own peat and coco supply. It also formulates the biological additives blended in. That combination helps standardize formulas like AGTIV REACH. The formula stays consistent across package sizes.

Frequently Asked Questions

Does PRO-MIX CCX need to be buffered before first use?

Premier Tech pre-processes the coco in CCX to reduce the sodium and potassium levels typical of raw, unbuffered coco, which cuts down on the calcium/magnesium buffering growers would otherwise need to do themselves. Growers running a calcium-sensitive feed program should still watch Ca/Mg levels through the first couple of feed cycles to confirm the substrate is behaving as expected in their specific system.

How does CCX compare to CPX, the 70/30 coco and perlite blend?

CCX holds more water (70-75%) than CPX (60-65%), so it suits growers who prefer longer intervals between waterings. CPX drains and dries back faster because of its perlite fraction, which is the better choice for growers running frequent irrigation cycles who want more aeration between waterings.

Is PRO-MIX CCX suitable for hydroponic systems?

Yes, it works well in drip-to-waste, recirculating drip, and automated fertigation setups where a clean, pH-stable, high-retention substrate is needed. The OMRI Listed status also carries through to organic hydroponic production, for growers who need that certification.

Can CCX be reused for a second crop cycle?

It can often be reconditioned and reused with proper sterilization between crops, but Premier Tech recommends checking EC buildup, physical breakdown, and microbial load first. Skipping that check risks carrying over salt buildup or pathogens into the next planting.
