Cannabis cultivation

Healthier roots. Heavier harvests.

Inline oxygen injection holds dissolved oxygen high from batch tank to dripper, so roots keep building and your inoculants can establish. Measured at GB Sciences: +15% final yield, one site. Installs in 1–3 days.

Why it matters in your rooms

Nutrient uptake is active transport, and the root pays for it with energy it can only make with oxygen. Hold dissolved oxygen high all the way to the root surface and the plant builds more root, the beneficial microbiology in your program gets the conditions it needs to establish, and root pathogens lose the low-oxygen pocket they depend on.

The problem

Your room is dialed in. Your root zone isn't.

You control light, VPD, EC and CO₂ to the decimal. Then the water enters the substrate and the measuring stops. Dissolved oxygen falls as roots and microbes consume it. Air stones lose efficiency within weeks. Biofilm thickens on drippers and root surfaces, adding oxygen demand of its own. In that low-oxygen pocket, uptake slows, root growth stalls, the aerobic biology you inoculated loses ground, and Pythium and Fusarium get the one condition they need to compete. It is the one input in the room without a probe on it.

The solution

Grow the root. Favor the biology. Lower the pressure.

We inject concentrator oxygen as ultrafine bubbles into the irrigation line you already run, and hold dissolved oxygen high all the way to the root surface. Roots build faster and finer, so there is more of the organ that does the feeding. Your aerobic beneficials get the conditions they were selected for, and root pathogens lose the low-oxygen niche they exploit. Continuous scouring keeps biofilm thin on lines and drippers. Oxygen is not a sanitizer: it works alongside your sanitation program and slows how fast a cleaned system slides back between events.

Who else runs it

Measured and reported in working rooms

Each figure names the site and who took the reading. One site is a result there, not a forecast for your rooms.

Filters cleaned once a week, not twice

The grower reports filter cleaning cut from twice a week to once a week, and attributes it to less biofilm build-up in the lines. It also reports dissolved oxygen held at about 22 ppm from the RO tank to the drip emitters.

What changes at the root

Root development you can lift out of the pot

Moving nutrients into a root cell is active transport, and active transport is paid for in energy the root can only make with oxygen. Hold dissolved oxygen high at the root surface and the plant spends that energy building root: finer laterals, more root hair, more absorptive area through the full depth of the medium. Root mass is the ceiling on everything above it.

The conditions your biology was selected for

Bacillus, Pseudomonas, Trichoderma and the rest of a standard inoculant program are aerobes. They colonize the rhizosphere where oxygen is, and they stall where it isn't. A root zone held aerobic between irrigations gives the biological program you already pay for the environment it needs to establish, not just the moment you dose it.

Take the low-oxygen niche away from Pythium

Pythium, Phytophthora and Fusarium are opportunists of the oxygen-poor root zone: the saturated pocket, the dead leg, the warm reservoir. Holding dissolved oxygen high takes away the condition they exploit and lowers pressure across the room. It lowers risk; it does not sterilize.

Crop steering with a margin underneath it

Aggressive dry-backs work until the wet phase runs hypoxic and the root zone pays for it. When oxygen stays high through irrigation, you have room to steer generative or vegetative on purpose, and the margin to do it every cycle instead of getting away with it once.

Thinner biofilm, drippers that keep feeding

Ultrafine bubbles carry a negative surface charge and scour drippers, lines and root surfaces with every cycle. Thin biofilm keeps emitters delivering evenly, and it is the difference between a sanitizer that contacts the surface and a dose spent on the layer above it.

Mother stock that keeps up

Root initiation is oxygen-limited before it is hormone-limited. Cultivators running oxygenated water on mothers and props report faster callus and more uniform rooting. CLTVTD Genetics reports 25–35% more cuts per plant from treated mother stock, with what its head grower describes as a healthier mother-stock root zone. That is cuttings off a mother, not flower yield.

Buyer questions

What cannabis cultivators ask before they buy

How do I buy it?

Three ways. Direct from Kairospace: an engineer sizes the system to your rooms 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 one to two harvests in a treated room against a control room, and pilot fees can credit toward the full system, up to 100% on structured trials.

What does it take to install?

A tie-in to your existing piping, done in 1–3 days, with hours of interruption on the treated line rather than days. In the installs pictured on this page the injector sits right after the batch pump, so the feed leaves the batch tank already carrying dissolved oxygen; the irrigation main, or the reservoir or return line on a recirculating system, are the other candidates, and the proposal names the point from your flow rate, pipe diameter and water source. Your side is a dedicated GFCI-protected circuit, commonly about 220 V / 30 A (the exact spec is in the proposal), access to the line and a place for the concentrator. Hardware arrives 4–6 weeks after the down payment.

I already run air stones or a venturi. What does this add?

Air stones and venturis dissolve air, and air is about 21% oxygen, so they top out near air saturation: about 9.1 mg/L at 20 °C (68 °F) and 8.3 mg/L at 25 °C (77 °F), and lower as the water warms. A stone in the reservoir also treats the reservoir, not the line after the pump. Our injector dissolves concentrator oxygen, about 93% pure, into the feed itself as ultrafine bubbles, so the oxygen travels with the water to the dripper. At GB Sciences the grower reports about 22 ppm held from the RO tank to the drip emitters. Keep your stones if you like; the proposal shows what the injector adds on your line.

Does it work with my ozone, peroxide or HOCl program?

Yes. Oxygen works alongside your sanitation program; it is not a sanitizer and does not replace one. Keep your products, dose points and schedule. What changes is the surface your sanitizer meets: ultrafine-bubble scouring keeps biofilm thin between events, so the dose reaches the pipe wall instead of spending itself on the layer above it. The injector core is titanium, and the proposal sets where the injector sits relative to your dose points.

Will the concentrator add heat and noise to my rooms?

Some, and we plan for both. The concentrators on our spec sheet draw 0.6 to 4.5 kW depending on model, roughly 2,000 to 15,400 BTU/h, and most of that ends up as heat where the unit sits. They are rated below 65 dBA and for 5–40 °C (41–104 °F) ambient. Plan it outside the canopy, in a fertigation or mechanical room that can be ventilated, with an oxygen line run to the injector. We size the unit and choose its location with you, and the proposal states its power draw.

Will it work with my inoculants?

The mechanism runs in their favor. Bacillus, Pseudomonas, Trichoderma and the rest of a standard inoculant program are aerobes: they colonize where oxygen is and stall where it isn't, so a root zone held aerobic between irrigations gives them the conditions they need to establish. That is a mechanism, not a colonization rate we have measured. Hold the oxygen, then measure your own rhizosphere.

How do we measure dissolved oxygen in the root zone?

With the instruments that come with the system: optical dissolved-oxygen meters, pH probes and data logging. On a pilot, dissolved oxygen, pH and your KPIs are logged from day one in both the control and the treated room, and you see the readings at every checkpoint. The results report is your data, not our marketing.

What does a pilot look like in a cultivation facility?

One room as control and one as treatment, over one to two harvests, instrumented the same way. We capture your baseline, 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. For scale: at GB Sciences we measured +30% biomass and +15% final yield, one site and two different metrics, not an expected value for yours.

Research & hardware

What the research says, and what we build

Each problem below is paired with the published work on it and with the hardware that puts the mechanism in your line. Figures are other people's trials unless marked KST field data.

Problem: Root growth is capped by the oxygen at the root surface
The Problem: Air stones lose efficiency within weeks, and demand only climbs — root mass grows, microbial load grows, the reservoir warms, and warm water holds less oxygen to begin with. As dissolved oxygen falls, roots shift from building tissue to holding on. Elongation slows, lateral branching slows, and the absorptive surface you need for the back half of the cycle does not get built.
What We Do: Ultrafine bubble injection holds dissolved oxygen high at the root surface, stable across cycles and temperatures, so the root keeps building instead of defending. In our own deployment at GB Sciences, biomass rose 30% and final yield rose 15% — two different metrics, and the gap between them is harvest index, drying and trim. That is field data from one commercial site under that site's conditions, not an expected value for yours.
Problem: You're overfeeding because your plants are under-absorbing
The Problem: Cultivators raise feed rates to compensate for poor uptake. But uptake isn't a dosage problem — it's an energy problem. Root cells pull nutrients against a concentration gradient, and that transport is paid for in ATP the root can only generate with oxygen. Add biofilm-coated lines and a root zone that swings anaerobic between irrigations, and you are paying more to absorb less.
What We Do: We raise the oxygen available where that transport actually happens, and the negative surface charge on ultrafine bubbles helps carry cations like calcium and potassium to root-hair surfaces. The lever here is absorption, not dosage — which is why cultivators who fix the root zone commonly find they had been running feed harder than the crop ever required.
Problem: Your biological program isn't colonizing the way the label says
The Problem: You are buying inoculants — Bacillus, Trichoderma, mycorrhizal blends — and the results move room to room and season to season. Almost every organism in those products is an obligate or facultative aerobe. Introduce them to a root zone that goes anaerobic between irrigations and they don't colonize; they persist, or they don't.
What We Do: Oxygen is the selection pressure in a root zone, and it acts continuously rather than at the moment you dose. Holding dissolved oxygen high favors the aerobic community you are trying to establish and disfavors the low-oxygen tolerant organisms you are trying to exclude — one lever, working in both directions at once. This is a mechanism, not a measured colonization rate: the honest instruction is to hold the oxygen and measure your own rhizosphere.
Problem: Pythium is one bad week away from wiping a room
The Problem: Recirculating systems are Pythium highways. One infected plant seeds the reservoir within hours. And the places these organisms survive a treatment are exactly the places a treatment can't reach — inside biofilm on a dripper, in a dead leg, in a saturated pocket at the bottom of a pot.
What We Do: Two things, and neither of them is sterilization. High dissolved oxygen removes the low-oxygen condition oomycetes need to get a foothold, which lowers pressure across the room. Continuous bubble scouring keeps biofilm thin, which is what lets a sanitizer contact the surface instead of spending itself on the matrix above it. Your sanitation program resets the surfaces; high DO slows how fast they rebuild before the next event.
Problem: Every gram of chemistry you add is a residue you have to test for
The Problem: Peroxide, hypochlorite and chemical biofilm treatments all leave something behind, and each one is a line on a COA and a stressor on the crop. Failed tests mean pulled batches and lost access to premium channels. Raising the dose to compensate for a system that keeps fouling makes both problems worse at once.
What We Do: A physically scoured, aerobic root zone means your chemical program has less to fight — lower rates, longer intervals, less crop stress for the same line held. We are not claiming to remove chemistry from your facility. We are claiming the chemistry has less work to do, and your COA has less to explain.
