Water restoration for horticulture
Roots need oxygen as surely as leaves need light, and irrigation water can carry it to them.
Roots breathe with every watering, and the crop shows it.
The same mechanism, on this water
Water fails from the bottom up: the oxygen runs out at the sediment, the root zone, or the sludge blanket first, and the trouble climbs from there. Nanobubble oxygenation, oxygen in bubbles small enough to stay suspended instead of rising and bursting, carries dissolved oxygen through the whole water column and down to where the failure starts, and adds nothing else. The technology pages lay the mechanism out in plain English, and how we measure shows the standard every claim on this site is held to.
The full page for greenhouse and irrigation reservoirs, the failure modes, the usual fixes and where they stop, and the timeline in ranges, is being written to the same standard as the pond and lake pages, with a section on when this isn't the right fix.
What the published work shows
Yield evidence is mixed and system-dependent: a 2025 floating-system study (Fiore et al., Horticulturae) found nanobubble aeration raised lettuce leaf quality without changing yield.
These findings describe nanobubble oxygenation as a mechanism, not an Alchemal unit. Our own installations publish their own record as case files.
The problems we treat here
Root rot in recirculating systems: the oxygen behind it
Flat, low-oxygen irrigation water: the hidden cost
Slow growth on recycled irrigation water: the oxygen limit
Poor germination and weak transplants: the oxygen behind them
Nutrient solution going anaerobic in closed-loop CEA
Biofilm and clogged drip emitters: the water behind it
Algae in an irrigation reservoir: the conditions behind it
Who we serve
Greenhouse growers
Under glass or poly you control light, heat, and feed, and you recirculate to save water and nutrients. The input that goes unread is the oxygen in the water reaching the roots, and a warm, recirculated feed runs short of it first. When the root zone cannot breathe, uniform crops turn uneven and the trouble starts at the roots.
Container nurseries
A container nursery lives on its irrigation water, and much of it is stored and recycled: captured runoff, a holding reservoir, a return that recirculates. Water that sits warm and still goes flat, and the crop reads it as slow, uneven growth and emitters that clog. The reservoir sets what the whole yard receives.
Hydroponic and CEA growers
A closed-loop CEA or vertical farm recirculates hard and runs warm under lights, which is exactly what pulls dissolved oxygen out of the nutrient solution. When the solution goes anaerobic it sours, uptake stops, and root rot follows, all at once. The oxygen in the loop is the number that decides whether it stays productive.
Cannabis growers
In a high-value indoor crop the margin sits in a small number of plants, and a root-zone problem you cannot see is the expensive kind. Recirculating rooms run warm and hard, so the nutrient solution loses its oxygen, and low-oxygen roots are where the water molds behind root rot take hold. What the water is doing decides how much of the room finishes clean.
The record
No Alchemal case file exists for greenhouse and irrigation reservoirs yet. Every installation is instrumented from day one, its record publishes either way, and until the first one is ready the methodology shows what we record, how we calibrate, and how we report what didn't move.
The arrangement
The arrangement is the same on every water we take on. It starts with a free written assessment that puts a baseline on paper and says whether oxygenation is the right fix here. If it is, an N-Series unit you own does the work, and Stewardship carries the seasons and the record from there.
