A closer look at growing
For the
plant curious.
Measure a little. Notice more. Seven small laboratories for gardeners who want to understand the conditions behind the growth.
Light Lab
Calculate daily light integral from PPFD and hours. Compare lighting schedules, target DLI, energy use and editable electricity rates.
Open lab ↗02 / Air & leavesVPD Lab
Calculate air and leaf VPD plus dew point. Explore an interactive temperature–humidity map with explicit assumptions and no universal green zone.
Open lab ↗03 / Water distributionIrrigation Check
Calculate irrigation runtime, water volume, catch-can application rate and lower-quarter distribution uniformity with a visual catch map.
Open lab ↗04 / Space below groundPot Lab
Calculate internal pot volume for cylinders and tapered round or square containers. Estimate added potting mix and whole bag quantities.
Open lab ↗05 / From seed to evidenceSeed Lab
Track germination on an interactive seed tray, compare A/B groups, chart cumulative emergence and export observations with Wilson intervals.
Open lab ↗06 / Your conditions, recordedMicroclimate Lab
Import sensor CSV, map columns, compare site temperatures and humidity, inspect daily heatmaps and export summaries locally in your browser.
Open lab ↗07 / A season in contextSeason Tracker
Compare historical seasons with cumulative GDD, rain and minimum temperatures. Import CSV or load NASA POWER daily data by coordinates.
Open lab ↗Useful numbers.
Visible assumptions.
Calculators turn your inputs into model results. Observation tools use the readings you provide. Examples are labelled, and weather data are identified separately from garden measurements.
Seed Lab saves its draft in this browser. Sensor files are analysed locally. Optional NASA POWER requests send the coordinates and periods you enter to NASA; no account is needed.
