Cannabis Fertigation: Precision pH and EC Automation
Cannabis is one of the most nutrient-sensitive crops a grower can cultivate. pH targets shift between vegetative growth (5.8-6.0) and flowering (6.0-6.3). EC requirements change dramatically from seedling (0.4-0.8 mS) to late flowering (1.6-2.2 mS). Miss these windows, and you get nutrient lockout, reduced trichome production, or diminished terpene profiles — problems that directly impact the value of your harvest.
The difference between a good crop and a premium crop often comes down to how precisely pH and EC are maintained hour by hour, not just day by day. Manual testing 2-4 times daily leaves 20-22 hours of unmonitored drift. NIDO ONE V2 closes that gap with 96 automated checks per day.
Why Cannabis Growers Choose NIDO
- Stage-specific recipes: Program different pH and EC targets for each growth phase — clone/seedling, vegetative, transition, early flower, late flower, flush. Save recipes and recall them for future grows. Consistency between cycles is what separates professional operations from guesswork.
- Environmental control: Humidity management is critical for preventing botrytis (bud rot) during flowering, when dense flower structures trap moisture. NIDO monitors temperature, humidity, and VPD in real time. With NIDO Plug modules, automate dehumidifiers, exhaust fans, heaters, and humidifiers based on actual conditions — not timers.
- Complete data logging: Every pH reading, every EC adjustment, every temperature fluctuation is logged. With NIDO Lab, access complete grow histories, compare cycles side by side, and document your process. This data is invaluable for optimizing recipes, training staff, and — in regulated markets — demonstrating process consistency for compliance.
- Compact and discrete: At 37x23x20 cm, NIDO ONE V2 is smaller than a shoebox. Operating noise is 53 dB (flow pump) to 63 dB (dosing pump) — quieter than a normal conversation. No bulky control panels, no complex wiring runs through the facility.
- 4 fertilizer channels: Configure A+B+C+pH- for most nutrient lines, or A+B+pH++pH- if your water source needs both up and down pH correction. Compatible with all liquid mineral fertilizers, phosphoric acid (pH down), and potassium hydroxide (pH up).
