MAINELY AG

Practical plant-physiology tools for controlled environments.
Built for growers who care about mechanisms, not mythology.

VPD CALCULATOR

Leaf-based vapor pressure deficit using air temperature, leaf temperature, and relative humidity. Phase-aware targets grounded in real plant physiology.

FERTILIZER MIXER

Combine multiple fertilizer inputs and calculate final N-P-K values using proper weighted averages. Built for real-world mixing, not label math.

FERTILIZER PREDICTOR

Predict nutrient outcomes from target ratios and inputs. Designed to explore feed strategies before they hit the plants.

VPD × TRANSPIRATION PULL — Ca, Mg, & K

Visualize how VPD alone drives transpiration stream pull and how calcium, magnesium, and potassium delivery shift across seedling, vegetative, and flowering stages.

VPD +

Expanded transpiration-pull model covering all major and micronutrients. Explore how VPD-driven flow alters nutrient delivery pressure, buffering behavior, and deficiency risk across growth stages.

BREEDER’S EQUATION

Predict response to selection using narrow-sense heritability and observed population shifts. Designed for small breeding populations with limited prior data.

BROAD-SENSE HERITABILITY

Partition phenotypic variance into genetic and environmental components using clonal replication. Designed to answer how much of what you observe is genetic versus environment, in this population and under these conditions.
