Just need PPFD × hours? Use DLI Calculator. Solar DLI and Crop DLI Analysis add the sun at your location and season; PPFD Calculator and Coverage Area size the fixtures themselves.
Fixture spacing and canopy coverage planning for grow rooms and greenhouses.
Pick your crop, ZIP code, month, and greenhouse glazing — this estimates the natural DLI reaching your canopy, adds your supplemental light, and shows the gap to the crop's target so you know exactly how much lighting you still need.
Convert PPFD and photoperiod to Daily Light Integral (mol/m²/day), and see the PPFD or hours you would need to reach a target DLI.
Target PPFD, blue %, and far-red by crop category and growth stage.
Stage-based lighting requirements for crop-specific planning.
PPFD mapping, heatmaps, and layout analysis for fixture planning.
Estimates average canopy PPFD from total fixture PPF over the canopy area, plus a uniformity estimate from beam-footprint overlap. For a rendered heat map with the full inverse-square light model, use the 3D view in /design.
Double-screen configurations for light & temperature balance in greenhouses.
Estimate solar DLI by location, season, and greenhouse operating assumptions.
Build and review horticultural lighting spectra and tunable channel mixes.
Visualize solar elevation, azimuth, and shading windows over the year.
Upload a canopy photo to compute RGB greenness indices (VARI/ExG/GLI) right in your browser, or enter pre-computed indices (NDVI, PRI, reflectance) from a spectral sensor for a plant-status read. RGB photos give a visible-light vigour proxy — a true NDVI needs a near-infrared camera — and the index-to-status mappings below are heuristic.

For day-to-day climate steering start with VPD (or Humidity Deficit for g/kg steering); use Heat Load and Psychrometric when sizing HVAC and dehumidification. RTA sets the 24-h mean from photosynthesis and prices a warmer target in CO₂ or fruit load — advisory only, it does not command hardware.
Linear extrapolation of warming and cooling-cost trend over a planning horizon. Coefficients are user-editable planning assumptions, not measured regional climate data.
CO₂ planning, target ppm guidance, and operating assumptions.
Deterministic diurnal high/low and natural DLI estimate from a current reading and latitude. Applies fixed diurnal offsets — it is not a live forecast API or a learned model.
Moisture load and energy relationship analysis for indoor farms.
Control sizing and system recommendations for grow environments.
Monitoring-oriented environmental calculator and review surface.
Cooling and HVAC sizing support for cultivation facilities.
Humidity deficit in g/kg (the Dutch grower standard) with vegetative/generative/exhaustion steering and air-exchange limits.
Specific Leaf Area analysis for growth-stage assessment using Kozai's methodology
Leaf Area Index for canopy light interception modeling and optimization
Air property calculations for HVAC and dehumidification workflows.
Sets the 24-h mean temperature from crop photosynthesis instead of light alone, and tells you how much CO₂ or fruit load a temperature rise costs. Advisory only: it does not send hardware commands.
Advanced thermal modeling & heat dissipation planning for grow rooms and greenhouses.
Penman-Monteith style transpiration and water loss estimation.
Directional vegetative-generative balance index from plant morphology. The index weighting and steering suggestions are heuristics, not a validated crop-steering standard — treat outputs as directional guidance, not prescriptive setpoints.
Quick vapor pressure deficit calculator for daily climate steering.
Dynamic setpoint adjustment based on weather forecasts for proactive environment control.

Custom fertilizer blend from raw salts (calcium nitrate, MKP, potassium nitrate). Salts are solved in sequence so cross-element contributions are netted out — K supplied by MKP and the N supplied by potassium nitrate are subtracted from the remaining targets so total N, P and K reconcile to your setpoints.
Irrigation timing and control planning for crop and substrate conditions.
Irrigation scheduling driven by DLI accumulation & drain targets.
Nutrient formulation and dosing support for fertigation planning.
Recirculating aquaculture system design & biofilter sizing.
Substrate moisture and media monitoring support for irrigation decisions.
Source water, alkalinity, and quality review for irrigation systems.

Derive Fv/Fm, ΦPSII, NPQ, qP/qL/qN, and ETR from PAM-fluorometer measurements, with stress interpretation and rapid light curves.
Crop scheduling and production planning simulation.
Heuristic disease-risk index from temperature, humidity and leaf-wetness thresholds. Based on published infection-condition ranges (e.g. Botrytis 15–25°C with prolonged leaf wetness) — a rules-of-thumb index, not a trained model.
Scores your environment against fixed reference setpoints (day temp 78°F, PPFD 800, CO₂ 1000 ppm, VPD 1.05 kPa, EC 2.0 mS/cm) and suggests which parameter to adjust first. Reference targets are generalized (not crop-specific); treat the suggestion as directional.
Batch economics (yield × price − costs) for a single grow cycle. This is a profit-and-loss estimator, not METRC-style regulatory seed-to-sale inventory traceability.
Integrated Pest Management scouting schedule and biocontrol budget estimate. Thresholds are rules-of-thumb (≈1 sticky trap per 500 sq ft), not a certified IPM standard.
Light-use efficiency (LUE) = daily biomass gain ÷ DLI, i.e. grams of dry matter produced per mol of PAR delivered. This is a direct ratio of your two entered values; the grow period only scales the cumulative biomass/light totals.
Model photosynthesis rates from light, CO₂ & temperature using a non-rectangular hyperbola light-response model (Thornley).
Optimal fruit load based on light level & plant development.
One-shot plant vitality and stress index from manually entered NDVI, leaf/air temperature and sap-flow readings. Stress coefficients are heuristic; this is a single snapshot, not continuous sensor/image monitoring.
Estimates health, vigor, nitrogen status and maturity from observed leaf color/shape and plant dimensions you enter. This is a rule-based estimate from hand-entered traits — it does not use images or identify a species/cultivar.
Week-by-week production planning and crop schedule modeling.
Yield Photon Flux — weights PPFD by McCree-style relative quantum yield for blue (~0.75), green (~0.85) and red (~1.0) wavebands to estimate photosynthetically effective flux and spectral efficiency.
