Free grow reference

Science-backed schedules for serious grows.

Turn genetics, system, and climate into a week-by-week nutrient plan. Profile targets first — products second. No hype, no paywall, no guru.

AI Grow Schedule Builder

Enter your cultivar, system, and environment. The demo engine computes stage targets and a week-by-week plan you can inspect.

Fill the form and generate a demo week-by-week nutrient schedule.

Schedule

Demo preview. Targets are illustrative ranges derived from system heuristics — not lab assays or yield guarantees. Educational framing only. Product mapping & affiliates come later.

Show us the plant. We'll rank the likely issues.

Upload leaf or canopy shots and get science-backed hypotheses with confidence ranks — linked to the directory. Educational triage, not a guaranteed ID.

Client-side only — images never leave your browser in this demo.
Context improves ranking in production; demo uses notes for flavor only.

Add plant photos and run the demo to see ranked hypotheses.

Ranked hypotheses

Demo preview. Production will use vision models plus your notes. These rankings are illustrative for educational triage — not a definitive identification or treatment prescription.

How it works

Three steps from your grow to a inspectable plan — calculator, not oracle.

01

Tell us your grow

Cultivar or traits, media/system, and environment. Optional climate zone shapes outdoor and greenhouse notes.

02

We compute profile targets

Stage EC, NPK ratios, Ca/Mg emphasis, and irrigation cadence — nutrient profiles before brand names.

03

Schedule + product map

Week-by-week plan with “why” blurbs. Later: curated products that match the same profile — disclosed affiliates.

Built to be verified

Cite sources

Articles and tool rules point to agronomy literature and manufacturer data sheets — not vibes.

Ranges, not guarantees

We publish stage bands and assumptions. Yield promises and miracle claims stay off the page.

Show the rules

Every schedule exposes the EC/NPK targets used so you can sanity-check against your meters.
