Water restoration for 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.
The problems we see on your water
What Alchemal installs and takes responsibility for
A greenhouse runs its water hard. In hydroponics (growing with the roots in water or an inert medium rather than soil) and in any recirculating system that returns the feed rather than running it to waste, the dissolved oxygen (the oxygen dissolved in the water) around the roots is drawn down by the crop, the media, and the biology, and a warm house under glass pulls it lower still. When the root zone (the water and medium around the roots) goes short, uptake stalls, growth turns uneven, and the water molds behind root rot get their opening.
Nanobubble oxygenation holds dissolved oxygen through the full water column and delivers it to the root zone with every watering, adding nothing else. We baseline the oxygen before sizing anything, at the reservoir and at the roots, install the system matched to your house, and Stewardship logs the oxygen against a baseline taken before any commitment. Where light, temperature, or the nutrient recipe is the real limit, the assessment says so. The N-Series unit is matched to the site, with a published target price band, and what we measure and how is published. The honest register here is root health and even establishment, not a promise about yield; the published figures and their scope sit on the horticulture overview.
Proof from greenhouse growers
The first installations for this audience are being instrumented now, and their case files publish when the record is worth reading. The methodology is already public: what we record, how we calibrate, and how we report what didn't move.
From your first note to the assessment
- You describe the water. A specialist reads it, replies with a plain answer, and says whether an assessment makes sense.
- Your water goes on the schedule. The first assessments and installations are being scheduled now; requests are answered in the order they arrive.
- The assessment puts a baseline on paper: dissolved oxygen top to bottom, clarity, the condition of the sediment, and a plan with a prediction attached. If oxygenation isn't the right fix, the report says so.
Questions greenhouse growers ask
Will installing this interrupt a crop cycle?
No. The system installs at the reservoir or the loop as it stands and runs continuously, with nothing added to the water except oxygen. Feeding, dosing, and irrigation all keep going while it runs.
How do you size a system for our greenhouse?
The assessment measures dissolved oxygen where it matters, at the reservoir and the root zone, and reads the load the crop and the loop put on it, then sizes to hold a reserve at your feed rates. An undersized system fails, so we will not quote one to win on price.
What does it cost to run against our current aeration?
That is a number we measure rather than claim. The argument is transfer efficiency: more of the oxygen you pay for stays in the water, so a given reserve costs less energy to hold. Stewardship meters it against a baseline taken before any commitment.
