- +25–35% cuts per plant · Customer-reported
CLTVTD Genetics reports the increase in average cuts per mother plant. These are propagation cuttings, not flower yield. - Dissolved oxygen held at 16–18 ppm · Customer-reported
Held in the range the grower targets. The grower credits the steady range for nutrient uptake, plant vitality and lower pathogen pressure. - Healthier mother-stock root zones · Customer-reported
The mothers showed more robust roots, which the grower links to higher-quality cuts and better propagation.
What the extra cuts are worth to you: extra cuts per mother each month × your own value per clone = added clone revenue per mother. Your cut counts and your clone price go in; this page supplies neither.
How it was set up
CLTVTD Genetics runs an indoor cannabis nursery in Sacramento. It raises mother plants in deep water culture (DWC) and sells first-generation clones derived from tissue-culture mothers, with regular plant-pathology screening of its stock. The goal of the trial was to raise dissolved oxygen (DO) in the mother room’s DWC system and hold it there.
- Setting. The Kairospace AG PACK treating the water that feeds the mother plants’ DWC reservoirs.
- The grower’s goals. Raise DO and hold it in the grower’s own 16–18 ppm target range; improve plant performance; keep pathogen pressure low on mothers and clones, alongside the nursery’s sanitation and screening; and validate the irrigation method.
- Comparison. Cuts per plant and DO against the nursery’s own recorded history before installation. No concurrent control room.
- Protocol. Data collected and verified through a customer feedback protocol and the nursery’s recorded historical data. No other changes were made to the grow during the multi-cycle trial.
- Duration. Multiple cycles; the number of cycles was not recorded.
What this does not show
- Every figure here is reported by the customer, not measured by Kairospace instruments.
- A +242% rise in dissolved oxygen was also reported, but no before and after readings were recorded, so it is not used here as a result.
- Cuts per plant are propagation output from mother stock, not flower yield, and say nothing about yield in a flowering room.
- One nursery, compared against its own history rather than a side-by-side control room. Dissolved oxygen supports the nursery’s sanitation and pathogen screening; it does not replace them.
In the customer’s words
“Since installing the Kairospace system, our DO levels are stable and showing significant improvements, with an increase in average cuts per plant of 25–35% while producing a healthier mother stock root zone. Finding the optimal range of Dissolved Oxygen has shown that 16–18 ppm is ideal for cannabis cultivation. This allows the most optimal rates for nutrient uptake, plant health, and pathogen prevention.”
The 16–18 ppm range is the grower’s own target from his own rooms, not a Kairospace recommendation.
Glossary
Deep water culture (DWC)
A hydroponic method in which roots hang in an oxygenated nutrient solution held in reservoirs. It is usually aerated with air pumps and diffusers, and the dissolved oxygen in the reservoir is one of the variables a DWC grower manages most closely.
Dissolved oxygen (DO)
Oxygen dissolved in the reservoir water. For DO in water, ppm and mg/L are numerically the same, so 16–18 ppm reads as 16–18 mg/L.
