01 — The Science

Roots breathe. Most irrigation water starves them of the chance.

Plant roots run on aerobic respiration — they need dissolved oxygen (DO) to convert nutrients into energy. Compacted soil, warm nutrient tanks, and dense hydroponic root mats all push DO down. Oxygenated water reverses that, and the effects compound through the whole plant.

Root Respiration

Higher DO in the root zone drives more active aerobic respiration, building stronger, denser root systems.

Nutrient Absorption

Healthy, oxygenated roots take up nitrogen, phosphorus and potassium more efficiently — critical in hydroponic solution.

Disease & Immunity

Low-oxygen conditions favor root-rot pathogens. Adequate DO suppresses hypoxia-related disease and builds resistance.

Growth & Yield

Oxygen-rich water accelerates growth and shortens time to harvest, with 10–30% gains recorded across trial crops.

Stress Tolerance

Under heat, cold or water-deficit stress, oxygenated roots keep functioning — improving resilience and recovery.

Cleaner Systems

Higher DO suppresses anaerobic bacteria and biofilm in nutrient tanks — less spoilage, less odor, longer clean-run times.

02 — How It Works

From PSA generator to root zone, in three steps.

A

Generate high-purity oxygen on site

The O2MOS unit uses Pressure Swing Adsorption (PSA) to separate oxygen from compressed air, producing a continuous high-purity O₂ stream without bottled gas or deliveries.

B

Dissolve it into water

Oxygen is injected and dissolved into the irrigation or nutrient-solution tank, raising dissolved-oxygen (DO) levels well above what untreated water carries.

C

Deliver it to the crop

Oxygen-rich water reaches the root zone through drip irrigation lines or microbubble diffusers such as airstones — matched to the growing system in use.

03 — Field-Proven Applications

Six crop systems, one working principle.

O2MOS has been installed across soil-based greenhouses, NFT hydroponics and cut-flower operations in Korea. The benefits below are drawn from those field installations.

FAQ

Common questions about O2MOS dissolved-oxygen irrigation.

What does O2MOS do for crops?

It uses on-site PSA oxygen generation to dissolve high-purity oxygen into irrigation or nutrient solution water, raising dissolved oxygen at the root zone so roots respire more actively, absorb nutrients more efficiently, and resist root-rot pathogens.

Which crops and systems is it used with?

Soil, substrate and hydroponic (NFT) production — including strawberries, paprika, tomatoes, roses, lettuce and other leafy greens, and microgreens/sprouts.

What gains have growers seen?

Trial crops have recorded 10–30% gains in growth rate and yield, plus reported improvements in sweetness, size, color uniformity and shelf life.

Does it need gas cylinder deliveries?

No. The O2MOS PSA generator produces a continuous high-purity oxygen stream on site from compressed air — no bottled oxygen, no scheduled deliveries.
