Questions
Is a SeedCadence report a germination certificate?
No. This report counts seeds with a root showing. It is for your own quality checks. It is not a germination certificate.
What does sprouted mean?
A seed has sprouted when you can see a small root coming out.
Which seeds has SeedCadence been measured on?
Maize, millet and rye, on photos from a public research set. See the results page for every number, with the mistakes.
What happens with my own photos?
The app counts them and tells you: We have not tested this seed yet. Please check the count. You can fix any seed.
What if the app is wrong?
Tap the seed and fix it. The app keeps both what it said and what you decided.
Can a signed report be changed?
No. A fix after signing makes a new version and keeps the old one.
Who can see my results?
Only the people in your own workspace.
Do you use my photos to train SeedCadence AI?
Never, unless you agree in writing.
What do I need?
A phone with a browser. For Lab tracking, a printer for the tray cards.
What happens to a photo I try without an account?
We delete this photo after 24 hours.
