Under the Hood Updates
5/26/2026
Today's update consists of entirely behind-the-scenes adjustments to improve overall performance, documentation quality, and application stability.
Under the Hood
- Documentation & UX Validation: We've implemented new automated validation and testing pipelines on the backend. This ensures that our documentation, user guides, and overall user flows remain synchronized and reliable going forward.
- Backend Performance: Minor optimizations to our backend services for smoother, more consistent database interactions.
- General Maintenance: Routine codebase maintenance and checks to ensure everything continues running efficiently.
As always, if you notice anything out of the ordinary, please let us know using the feedback button in the app!
UX and Documentation Improvements
4/28/2026
Today's update focuses on refining the user experience through more accurate data visualization and improved discovery in our documentation.
Feed Log Improvements
- Temporal Awareness in Charts: The measurements chart in Feed Logs now uses a linear time scale. This means gaps between feeding entries are now visually represented proportionally, making it easier to spot trends and drift over time.
- Smart Sorting: The Feed Logs table now defaults to showing your most recently modified logs at the top.
Enhanced Documentation
- Local Search: We've enabled a powerful local search (Ctrl+K) in the documentation guides, allowing you to find specific nutrient concepts or mixing tips instantly.
- Pro Tips: New expert callouts have been added throughout the guides to explain the science and best practices behind the solver settings and cost optimization.
Under the Hood
- Significant performance and code quality optimizations in the frontend Vue components.
- New backend performance rules to ensure cost-efficient and fast database interactions.
Unified Observations
4/11/2026
We have just rolled out a refinement to the Feed Log system. This update provides a more observation-based model for reservoir management.
Status Check-ins vs. Feeding Events
To support this new model, we've introduced dedicated shortcuts:
- Log Status: For quick environment monitoring (pH, EC, Temp). This keeps your log clean by hiding additives columns for that row.
- Log Feed: For when you are actually adding water or substances.
Introducing the Smart Top-Off Calculator
This tool is designed to move your reservoir toward a target mixture using simple ratio logic. It automatically detects your last recorded state and warns you if your planned additions exceed your reservoir's historical maximum volume or if the target is unreachable.
These updates represent a significant shift in how data is stored in the background. While the migration is seamless, these features are considered Active Testing. Please report any issues via Feedback.
Minor UX Updates
3/20/2026
Today's update brings a few minor refinements to our user interface, particularly for folks exploring without an account.
UI Polish
- Improved Login / Logout handling with the new anonymous access system
- Minor animation flourishes
- Improved handling of anonymous permissions throughout the app
- Improved backend security checks
As always, feedback is welcome!
Further Anonymous Improvements
3/18/2026
Some new features and a little under-the-hood improvements.
Shared Mixtures & the Editor
We want to make it as easy as possible to learn from the community. Anonymous users can now open shared mixtures directly in the Mixture Editor.
This allows you to take a formula shared by a registered user, experiment with different nutrient concentrations, and see how varying water quality affects the results—all before you even create an account. It's the perfect way to test-drive the power of our optimization engine with real-world examples.
Icon Performance Improvements
Behind the scenes, we've completed a migration of our icon system. We've moved to a streamlined SVG path system.
This should further improve the site speed as well as better handle multiple dimensions and resolutions.
We Value Your Feedback
