Built for home and hobby cultivators

Track every flush.
Grow smarter.

Mushroom.casa Grow Log is a cultivation tracker for people growing at home. Record each batch from spawn through to harvest, log yields and contamination, and let the app calculate biological efficiency so your next run is measurably better than the last.

Three steps from notes to numbers

The log is designed to take seconds per entry, because the log only works if you actually keep it.

Step 1

Log the batch

Species, substrate recipe, spawn type, inoculation date and container count. Five fields, one minute.

Step 2

Track it through the stages

Move the card as the batch progresses. Harvest weights and substrate weight become biological efficiency automatically.

Step 3

Compare and improve

See which recipes and species actually performed, and change one variable on the next run instead of guessing.

Everything a grow journal needs, and nothing it does not

Purpose-built for cultivation records. No social feed, no wild mushroom identification, no advice about what to do with your harvest.

Drag-and-drop batch board

Move each batch across seven stages — spawn prepared through archived — and see at a glance what needs attention today.

Analytics that answer questions

Harvest weight over time, BE% by species, yield per flush, contamination trend, and best-performing substrate recipes.

Live yield calculator

Enter substrate weight and species, get a projected yield range, and compare it with what you actually harvested.

Contamination tracking

Record contaminant type, affected containers and date. Your contamination rate is calculated per container, not per batch.

Recipe library

Save substrate recipes with exact ingredient weights and tags, then compare their measured biological efficiency side by side.

Stage timeline with progress rings

See how many days each batch has spent in its current stage against the typical duration for that stage.

Flush curves

Chart yield per flush to spot the point where a substrate is spent and a batch is ready to retire.

Photo log with lightbox

Drag photos straight onto a batch, caption them, and view them full screen. Stored privately in your own folder.

Reminders you control

General cultivation reminders for stage changes, flush windows, and misting or fan checks. Email or in-app, your choice.

Installable and works offline

Add it to your home screen. Active batches stay viewable without a connection and sync when you are back online.

Keyboard-first

Command palette on Cmd or Ctrl+K, N for a new batch, H to log a harvest, and / to search. Every action reachable without a mouse.

Your data, exportable

Export everything as CSV or JSON at any time, and delete your account permanently from Settings when you want to.

Guides for getting the numbers right

Short, practical write-ups on logging, biological efficiency, contamination and substrate recipes.

Built around how growers actually work

These are placeholder quotes to show the layout. Swap them for real feedback from your own users before launch.

“I was keeping notes in three different places and still could not tell which substrate mix was actually working. Two runs through the log and the answer was obvious.”

“The contamination rate per container changed how I think about losses. One tub out of twelve is not the same as one out of two, and now I can see which it is.”

“Being able to see the flush curve next to the recipe that produced it is the whole reason I keep logging. It is the only way I have found to improve deliberately.”

Frequently asked questions

What the app does, what it deliberately does not do, and how your data is handled.

Your next grow deserves better records than a notes app

What this app is not

Mushroom.casa Grow Log does not identify wild mushrooms and does not provide edibility, dosing or consumption guidance. Cultivation laws vary by jurisdiction and you are responsible for complying with the rules where you live. Nothing here is medical advice.
