Consistent Greenhouse Water pH Control — Same Job as Sulfuric Acid, Plus CO₂ Enrichment
ECO2MIX does exactly what sulfuric or citric acid injection does for water pH control: automated, continuous, precise. Target pH is maintained within ±0.1 regardless of water source variation or flow rate changes. No manual titration, no guessing.
The differentiator that mineral acids cannot replicate: CO₂ enrichment. After carbonic acid lowers water pH and the irrigation water reaches the root zone, the CO₂ component off-gasses into the soil environment, feeding microbial biology and contributing to canopy-level enrichment as water warms. And because carbonic acid leaves no residual salts, conductivity in recirculating systems stays stable. The salt accumulation problem that builds with sulfuric or citric acid over time does not occur.
ECO2MIX provides the equipment, CO₂ supply, installation, monitoring, and maintenance. You pay a fixed monthly fee. There is no capital cost, no chemical storage, and no maintenance burden on your team.

Why Greenhouse Growers Choose ECO2MIX
Reliable Water pH Control
Automated pH probe feedback holds your target regardless of flow rate or source water variation. Consistent water quality, every irrigation cycle.
CO₂ Added to Your System
Carbonic acid is dissolved CO₂ in water. That CO₂ reaches the root zone with every irrigation, stimulating microbial activity and supporting plant respiration. No mineral acid provides this benefit.
Monthly Service Model
No capital investment. ECO2MIX owns and operates the equipment. Fixed monthly cost covers equipment, CO₂ supply, monitoring, and all maintenance. Budget certainty from day one.
No Hazardous Storage
CO₂ is food-grade and already present in your greenhouse atmosphere. No bulk acid tanks, no corrosion risk, no hazmat compliance paperwork. The same chemistry as sparkling water.
Recirculating System Compatible
Carbonic acid leaves no residual salts. CO₂ reverts to gas and water after adjusting pH. Recirculating systems stay cleaner, and nutrient solution conductivity stays where you set it.
We Handle Installation
ECO2MIX handles site survey, equipment sizing, installation, and commissioning. We design the system to your water source and irrigation configuration before anything ships.
How It Works
CO₂ Injection at the Source
The ECO2MIX reactor connects inline at your main water source, upstream of your nutrient dosing system. A continuous pH probe reads your incoming water, and the controller adjusts CO₂ injection automatically to hit your target.
Water leaving the reactor is at the pH you specified. Your fertigation system, drip lines, and NFT channels receive pH-correct water on every cycle. There is nothing to titrate, no manual acid additions, and no risk of overdosing.
Remote monitoring means ECO2MIX can see your system data in real time. Any anomaly triggers a service response before it affects your crop.
- Inline installation, compatible with any irrigation system
- Target pH held automatically
- Remote monitoring and alerts
- CO₂ supply managed and refilled by ECO2MIX
- Monthly service contract with fixed pricing
Typical Greenhouse Target
Optimal for most greenhouse crops. ECO2MIX can hold any target your crop requires, including lower pH for blueberries or specialized substrates.
CO₂ Benefit
Dissolved CO₂ in irrigation water reaches the root zone and stimulates microbial respiration. This is a secondary benefit unique to carbonic acid that mineral acids cannot replicate.
Carbonic Acid vs. Mineral Acids in Greenhouse Settings
| Carbonic Acid (ECO2MIX) | Sulfuric Acid | Citric / Phosphoric Acid | |
|---|---|---|---|
| Residual salts | None. CO₂ reverts to gas. | Sulfate buildup over time | Phosphate / organic load |
| CO₂ to root zone | Yes, stimulates microbiology | No | No |
| Hazardous storage | None | Bulk acid tank required | Lower hazard, still chemical |
| Recirculating compatibility | Excellent | Salt accumulation risk | Adds organic load |
| Service model available | Yes, fully managed | Self-managed | Self-managed |
Other Benefits
- CCOF-approved for certified organic production — compare to sulfur burner
- No bulk acid storage or hazardous materials paperwork on-site
- Fixed-price service contract with no capital investment required
