Water restoration for 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 problems we see on your water
What Alchemal installs and takes responsibility for
A high-value indoor crop concentrates the risk. The whole margin can ride on a small number of plants, so a root-zone problem that spreads unseen is the costly kind. In hydroponics (growing with the roots in water or an inert medium rather than soil) and in any recirculating room, the dissolved oxygen (the oxygen dissolved in the water) around the roots is drawn down by the crop and the biology, and a warm room under lights pulls it lower still. When the root zone (the water and medium around the roots) goes short, the water molds behind root rot, Pythium and Phytophthora, get their opening, and they can move through a recirculating system fast.
Nanobubble oxygenation holds dissolved oxygen through the full water column and delivers it to the root zone continuously, adding nothing else, which matters where every input has to be accounted for. We baseline the oxygen before sizing anything, install the system matched to the room, and Stewardship logs the oxygen against a baseline taken before any commitment. The honest register here is root health, not a promise about yield or potency. Where a room needs cleaning or filtration, 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.
Proof from indoor 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 indoor growers ask
Does this add anything to the water we have to account for?
No. The system adds oxygen and nothing else, so there is no input to log against a compliance program or a testing regime beyond the dissolved oxygen itself, which Stewardship measures for you.
How do you size for a recirculating room?
The assessment baselines dissolved oxygen at the reservoir and the root zone and reads the load the room puts on it, then sizes to hold a reserve at your feed and temperature. An undersized system fails, so we will not quote one to win on price.
Will installing this interrupt a running room?
No. The system installs at the reservoir or the loop as it stands and runs continuously. Feeding, dosing, and irrigation keep going, with nothing added to the water except oxygen.
