Managing nutrient reservoirs when water evaporates or plants consume nutrients mid-cycle can be tricky. Starting today, you can access the Top-Off Calculator anywhere you plan, edit, or log your feeding routines!

Top Off Reservoirs Without Guesswork

When water levels drop or EC drifts in an active reservoir, dumping your entire nutrient batch is wasteful. The Top-Off Calculator determines the exact substance amounts needed to bring your current tank volume back to your target PPM ratios.

You can now use the Top-Off Calculator directly across all major app tools:

• Mixture Editor: Access top-off calculations right from the optimization toolbar while working on nutrient recipes.
• Feed Schedules: Calculate mid-cycle reservoir top-offs directly within multi-week feeding routines.
• Feed Logs: Compute and record tank adjustments on the fly while logging daily measurements and water additions.

Updated Mixture & Feeding Guides

We've updated our Mixtures Guide with step-by-step visual walkthroughs showing how to calculate top-off amounts, adjust for evaporation, and maintain precise nutrient ratios throughout your growing cycle.

As always, if you have feature requests or feedback, let us know using the feedback button in the app!
