Grow tools
Utilities designed to make a decision, not to generate content. Each one is in active development — previews below show exactly what they will take in and return.
Approach
Why these three tools
Growers get stuck at the same three points: choosing genetics, estimating cost and sizing a build. Each tool removes one of those blockers.
Opinionated defaults
Sensible starting values so you are never staring at an empty form.
Explained output
Every result shows the reasoning, so you learn the rule rather than the number.
No account required
Tools run in the browser. Nothing to sign up for, nothing stored.
