Boosting Radish Microgreen Yield by 30% and Accelerating Growth With NanobOx Nanobubbles

Nanobubble Insights has carried out multiple controlled trials showing that NanobOx nanobubble-treated water can increase radish microgreen yield by more than 30%, while also enabling trays to reach market-ready size up to one day earlier. These gains were achieved without changing lighting, substrate, seed rate, or nutrient recipe—only the water treatment was different. For high-throughput microgreen systems where margins are tight and rapid turnover is essential, these results point to a powerful opportunity to increase profitability and operational efficiency using NanobOx technology.

The Challenge

Radish microgreens grow rapidly, leaving very little room for improvement. Small changes in oxygen availability, moisture dynamics, or nutrient transport can greatly influence:

Biomass accumulation
Shoot strength
Root structure
Harvest timing

The goal: Can nanobubble-enriched irrigation water meaningfully increase yield or accelerate growth without any other changes to the production system?

The Approach

Experiments were conducted in a controlled vertical farming environment using coco coir substrate:

Trial 1 — Yield Comparison (7 days)

Control: Standard filtered water
NanobOx treatment: Water enriched with nanobubbles
All other variables identical (seed density, substrate, nutrients, lighting)

Objective: Measure yield differences at typical harvest time.

Trial 2 — Harvest Timing Study (Days 5–7)

Trays harvested on Days 5, 6, and 7
Measured fresh weight and yield per gram of seed

Objective: Identify whether nanobubbles speed up maturity.

The Results

1. Over 30% higher yield at harvest

NanobOx-treated trays showed:

Stronger turgor
Thicker stems
More vigorous, dense root systems
Significantly greater fresh weight (>30% increase)

Across repeated cycles, this yield enhancement remained consistent.

2. Faster growth and earlier harvest readiness

Nanobubble irrigation accelerated crop development:

Day 6 nanobubble trays reached the same weight as the Day 7 control
Faster canopy coverage earlier in the cycle
Higher efficiency measured as yield per gram of seed

This effectively gives growers an extra harvest day—a major productivity benefit in microgreens production.

3. Better seed efficiency and biomass accumulation

NanobOx water improved:

Nutrient transport
Root oxygen availability
Moisture balance in the substrate

The result: More output from the same amount of seed, energy, and labour.‍

Why It Matters

For commercial microgreen producers, even small performance increases translate into major gains. NanobOx delivers:

30%+ more sellable product per tray
1 extra harvest day per week, depending on rotation
No change to workflow, inputs, or system hardware
Compatibility with existing irrigation and fertigation setups
Immediate improvements without reconfiguration or downtime

This level of impact—driven purely by oxygen-rich nanobubble water—showcases the efficiency and effectiveness of NanobOx as a production optimisation technology.

Next Steps

Nanobubble Insights is now expanding this work through:

Multi-cycle yield validation
Trials to improve uniformity across trays
Testing the influence of seed density and irrigation frequency
Mapping oxygen and nutrient distribution in substrate
Larger-scale replication suitable for publication and partner due diligence
