Canopydew: Greenhouse Lab
Support
Canopydew is an offline iPhone and iPad greenhouse planning workspace. No sign-in or subscription is required.
Create or duplicate a zone
- Open Zones and tap the plus button.
- Choose a new zone or duplicate the selected plan.
- Enter the zone identity, crop context, stage, altitude, planning bands, and notes.
Build the 24-hour plan
Open Schedule to edit air temperature, relative humidity, leaf-air offset, PPFD, and CO2 for each hour. Apply Day Profile writes the visible values to every lit hour. A valid imported CSV must contain exactly one row for every hour from 00:00 through 23:00.
Interpret the climate workspace
Climate calculates values from the saved hourly entries. The what-if controls are temporary and do not change the stored plan. Target RH is an equation result for the selected target leaf VPD; it is not an equipment instruction.
Document sensors and operations
Open QA to record sensor kind, placement, representative status, shielding, aspiration, calibration date, and notes. Use Schedule to add operating events. The readiness result checks documentation completeness and entered limits; it is not a crop-health score or safety certification.
Export or back up a plan
Open Export to share an individual PDF, JSON, or CSV. Complete Review Packet creates all three and presents them together. Before deleting the app or changing devices, export the plan JSON or complete packet for each zone. Canopydew does not operate a cloud-sync service.
Import validation
Plan JSON must match Canopydew's documented structure. Schedule CSV must include six columns and 24 unique valid hours. Invalid or incomplete files are rejected without replacing the saved plan.

Operating boundary
Canopydew does not read sensors, diagnose plants, predict crop performance, or control equipment. Confirm crop-specific targets, calibrated measurements, equipment limits, and current qualified guidance before making operational changes.
Report a problem
Email support@shadowfetch.com with the device model, iOS or iPadOS version, screen involved, and steps that led to the issue. Do not attach confidential operating data unless you are authorized to share it.
