Allowing temperature to vary within a range over 24 hours while maintaining the same average. Saves energy while maintaining growth.
The total amount of photosynthetically active radiation (PAR) delivered to plants over a 24-hour period. Measured in mol/m²/day.
Programs where utilities pay you to reduce energy use during peak demand periods. VibeLux automates participation.
Organization that qualifies commercial lighting products for efficiency and performance. DLC listing often required for utility rebates.
Percentage of irrigation water that drains from the growing media. Indicates irrigation efficiency and salt management.
A measure of the salt/nutrient concentration in water or growing media. Higher EC means more dissolved nutrients.
VibeLux's zero-upfront-cost model where you pay only from energy savings or yield improvements. No savings = no payment.
Absolute humidity difference between inside and outside air. Used in Dutch greenhouse climate control. Measured in g/m³.
Systematic approach to pest control using multiple strategies: prevention, monitoring, biological controls, and targeted treatments.
Total one-sided leaf area per unit ground surface area. Indicates canopy density and light interception.
Marijuana Enforcement Tracking Reporting Compliance - seed-to-sale tracking system used in multiple US states for cannabis.
Proportional band control that gradually adjusts heating/cooling based on temperature deviation from setpoint. Prevents overshooting.
Concentration of dissolved nutrients in water. 1 PPM = 1mg/L. Different meters use different conversion factors from EC.
The highest amount of electricity used during a billing period. Often charged at premium rates. Major cost driver.
The duration of light exposure plants receive in a 24-hour period. Critical for controlling vegetative growth and flowering.
The total amount of PAR light emitted by a fixture per second. Measured in μmol/s. This is the fixture's total light output.
The amount of photosynthetically active radiation (PAR) hitting a surface per second. Measured in μmol/m²/s.
Light wavelengths from 400-700nm that plants use for photosynthesis. This is the spectrum of light that drives plant growth.
The number of fruits/flowers a plant is supporting. Higher plant load pushes the plant more generative.
Measure of acidity or alkalinity on a 0-14 scale. 7 is neutral, below 7 is acidic, above 7 is alkaline. Critical for nutrient availability.
Ratio of total facility energy to energy used by cultivation equipment. Lower is better. Industry average: 1.5-2.0.
DLC's database of tested and qualified lighting fixtures. VibeLux integrates this data for accurate lighting designs.
The amount of water vapor in the air expressed as a percentage of the maximum amount the air could hold at that temperature.
Greenhouse design that recirculates air through climate chambers, allowing better climate control and energy efficiency.
Weekly measurement of plant stem thickness. Key indicator of plant balance and vigor in Dutch cultivation.
The difference between the amount of moisture in the air and how much moisture the air can hold when saturated. Controls transpiration rate.
The balance between vegetative growth (leaves, stems) and generative growth (flowers, fruits). Key concept in Dutch tomato cultivation.
Amount of biomass produced per unit of water consumed. Key metric for sustainability and profitability.
VibeLux's systematic approach to increasing yields through optimized genetics, environment, nutrition, pest management, and harvest timing.
