More root all cycle, even when the reservoir runs warm.
Ultrafine-bubble oxygen for DWC, NFT and towers keeps the root zone aerobic and your beneficials working, alongside your sanitation program. Southern Nevada vertical farm: 24.16 mg/L dissolved oxygen in treated towers vs 8.05 mg/L in control towers.
Why it matters in your system
Root surface area sets the ceiling on everything you harvest. We hold dissolved oxygen high all the way to the root surface, so roots keep building through the warm months, your aerobic beneficials and nitrifiers keep working, and root pathogens lose the low-oxygen niche they depend on.

Summer is when the ponds crash.
In DWC ponds, NFT channels and vertical towers, the root zone runs on the oxygen dissolved in the water. Warm water holds less of it while roots and microbes use more, so the reservoir runs short exactly when the crop is growing fastest. Roots brown, growth slows, one tower lags the next, and a pond that looked fine last week can crash. Air stones top out at air saturation. The chiller buys margin by running hardest in the months you can least afford it.
Put oxygen in. Keep the root zone aerobic all cycle.
We inject concentrator oxygen as ultrafine bubbles into your supply line or reservoir, so dissolved oxygen sits well above what air can deliver at the same temperature. Roots keep building through the warm months, the aerobic beneficials and nitrifiers in your system keep working, and Pythium loses the low-oxygen pocket it exploits. Continuous scouring keeps biofilm thin on channels and emitters. It fits leafy greens and herbs in DWC, NFT, vertical towers and recirculating greenhouse systems, and it ties into the piping you already have.

Measured in towers, reported in ponds
Two CEA sites, and who took each reading. Single sites under their own water and crops: a result there, not a forecast for yours.
24.16 vs 8.05 mg/L · measured
Dissolved oxygen in treated towers against untreated control towers on the same nutrient profile, with photoperiods and water cycles synchronized. Two validation series of a ~45-day lettuce cycle, treated for about 28 days from transplant.
~3,000 g vs ~2,000 g top tower · measured
Total wet weight at harvest, top treated tower against its control; the second pair read about 2,500 g against 1,800 g. Brix read about 8% in both treated towers against about 6% and 5% in the controls. Approximate tower totals, not per-plant yield.
15 ppm held · no pond crashes reported

What changes in your system
Headroom for warm reservoirs
Air can only put so much oxygen into water: about 9.1 mg/L at 20 °C (68 °F) and 8.3 mg/L at 25 °C (77 °F), and less as the reservoir warms. Injected concentrator oxygen is not capped there. In the Southern Nevada farm, treated towers read 24.16 mg/L against 8.05 mg/L in the controls. That margin is what a warm reservoir needs in summer.
Fewer reasons for a pond to crash
Low oxygen is where a DWC pond starts to go wrong: roots brown, Pythium gets a foothold, the nitrifiers slow down. A commercial spinach grower running 10,000-gallon ponds (about 38,000 L) reports holding 15 ppm dissolved oxygen through 2023–2024 with no pond crashes. That is one grower's report, with no control pond, not a guarantee.
Root mass that carries the crop
Everything you harvest is downstream of how much root the plant builds, and root building runs on oxygen. In published research, oxygenating the root zone raised root mass by up to 126%. At the Southern Nevada farm, the top treated tower weighed about 3,000 g at harvest against about 2,000 g for its control, with larger root systems visible in the harvest photos.
Beneficials and nitrifiers that keep working
Bacillus, Pseudomonas, Trichoderma and your nitrifying population are all aerobes. They colonize where oxygen is and stall where it isn't. Holding DO high at the root surface gives your biological program the environment it needs to establish, instead of a root zone that swings anaerobic between irrigations and resets it every time.
The same water at the last tower
Coarse bubbles surface and leave. Ultrafine bubbles persist far longer than coarse bubbles, so the oxygen travels with the water down channels and up towers instead of escaping at the reservoir. Continuous scouring keeps biofilm thin on emitters and channels, which helps keep flow even from the first tower to the last. Check it with the optical DO meter that comes with the system.
Less of the oxygen job on the chiller
A chiller does two jobs: it holds the root-zone temperature your crop needs, and it raises how much oxygen the water can hold. Injected oxygen covers the second job. How far that lets you move a setpoint depends on your crop's temperature target, so a pilot measures it before you change anything.

What CEA and hydroponic growers ask before they buy
How do I buy it?
Three ways. Direct from Kairospace: an engineer sizes the system to your flow and reservoirs and quotes it. Through your hydro store: ask your store for Kairospace, or tell us your state and we will connect you with the dealer that serves you. Or lease-to-own, on 3–4 month terms with lease fees credited toward the purchase. If you want proof first, a pilot runs treated towers, channels or ponds against a control, and pilot fees can credit toward the full system, up to 100% on structured trials.
What does it take to install?
The injector goes inline on the supply line or at the reservoir; the proposal names the injection point from your flow rate, pipe diameter and water source. It ties into your existing piping in 1–3 days, with hours of interruption on the treated line rather than days, scheduled around your irrigation windows. Your side is a dedicated GFCI-protected circuit, commonly about 220 V / 30 A (the exact spec is in the proposal), and a place for the concentrator outside the grow space. Hardware arrives 4–6 weeks after the down payment.
Will it hold up when the reservoir warms in summer?
That is the case it is built for. Air saturation falls as water warms, from about 9.1 mg/L at 20 °C to 8.3 mg/L at 25 °C, while demand rises. Injected concentrator oxygen is not capped by air saturation: ultrafine bubbles have demonstrated dissolved oxygen above 30 mg/L, in our deployments and in published research. That is an achievable concentration, not a level every system holds. The DWC grower in our case study reports holding 15 ppm in 10,000-gallon ponds; a pilot measures what yours holds.
Can I run my chiller less?
It depends on your crop. A chiller holds the root-zone temperature the crop needs and, as a side effect, lets the water hold more oxygen. Injected oxygen takes over that second job, so the question becomes how warm a root zone your crop tolerates. We look at your temperature targets with you, and a pilot measures the result before you change a setpoint.
Does it replace my sanitation program?
No. Oxygen is not a sanitizer; it works alongside your sanitation program, whether you run ozone, peroxide, hypochlorous acid or chlorine. Keep your products and dose points. What changes is the surface they meet: ultrafine-bubble scouring keeps biofilm thin between events, so the dose reaches the pipe wall instead of spending itself on the layer above it.
What does it do for my beneficials and my nitrifiers?
Bacillus, Pseudomonas, Trichoderma and the nitrifying population a recirculating system depends on are all aerobes. Holding dissolved oxygen high favors that aerobic community and disfavors the low-oxygen tolerant organisms you are trying to exclude, instead of a root zone that swings anaerobic between irrigations. That is a mechanism, not a colonization rate we have measured for your crop. Hold the oxygen, then measure your own rhizosphere.
What does a pilot look like?
One bench, channel, tower group or pond as control and one as treatment, instrumented the same way, with dissolved oxygen, pH and your KPIs logged from day one. We capture the baseline first, agree the success criteria in writing, and review the readings with you at agreed checkpoints. You get a written results report, baseline against treated. Scale up with pilot fees credited toward the full system, or stop and keep the data.
