Measure inside the pot.
Use the pot’s interior dimensions and select centimetres or inches before entering them. Leave room below the rim and subtract the approximate volume occupied by retained roots and soil. A tapered pot needs both its top and bottom diameters.
For example, an inside top diameter of 24 cm, bottom 16 cm, height 22 cm, 2 cm headspace, 1 L root ball and 10% extra give about 5.64 L of new mix. Irregular shapes and compressed materials can change the amount you actually use.
Select Build a mix with this amount to carry the result into the mix builder. Parts are proportions: a 12 L batch at 3:1:1 uses 7.2 L, 2.4 L and 2.4 L. Enter the package size you can actually buy; the number of bags rounds upward.
Open the measuring tool ↗Take a clear list with you.
Download printable checklist saves an HTML document with your ingredient quantities and buying list. Open it in your browser, then choose Print and, if available, Save as PDF. The document includes its fonts and logo, so it can be opened offline.
Choose A4 for the reviewed print layout. Your browser controls page size, margins, scaling and whether it adds a URL/date header or footer. Switch those browser headers and footers off for a cleaner sheet. Long ingredient names may need an additional page.
The plain-text shopping list is an alternate format. It contains the same quantities but does not include the designed page layout. Neither format purchases supplies or changes a store’s basket.
Build a printable list ↗Keep a backup of your growing story.
Add dated observations as your plant changes. Use Correct to fix an entry or Delete to remove that entry. Choose your own check dates and use Today, Upcoming, Overdue or Completed to review them. A check date means inspect the plant before deciding whether to water.
Download shown checks as an .ics file for an editable calendar copy. It contains plant names and room labels, but omits journal notes. No live calendar sync or push notification is created. After editing or deleting a check here, update any imported calendar copy separately; calendars differ in how they handle re-imports.
Your journal stays in this browser at the website address where you saved it. A different browser, a private session, a different device or a change from a preview address to indoorjungle.co has a separate journal. Clearing browser data can remove the records.
- Choose Export JSON backup in the journal and keep the downloaded file somewhere you control.
- Open the journal in the destination browser or website address.
- Choose Import a backup and select that JSON file.
- Review the counts of new plants, observations and checks, plus any conflicts, then confirm the import.
Import adds new plant, observation and check IDs. Existing entries and plant details are kept when imported copies conflict; importing the same backup again does not duplicate it. Version 1 and 2 backups are supported: under 5 MB, up to 500 plants, 250 dated observations and 200 checks per plant. A printable journal page is useful for reading, but JSON is the format that restores editable records.
My journal is empty. What should I check?
Confirm you are using the same browser and website address, outside private browsing. If you have a JSON backup, import it. There is no cloud account or server copy from which we can recover browser data.
A change could not be saved.
Browser storage may be blocked or full. Export visible records first. Avoid clearing site data until you have a backup. Try the backup in a browser that permits local storage.
Do check-in dates tell me when to water?
No. They are your own reminders to inspect the plant. Soil, drainage, temperature and light change how quickly a pot dries. Use the plant’s source-backed care notes and your observations.
Read the answer in context.
The grow-light tool needs a measured PPFD reading, not lamp watts or a phone brightness reading. The humidity tool estimates air vapour-pressure deficit; it does not measure leaf temperature or prescribe a target. Each calculator explains its method and limits below the result.
The scientific-name index and the care library use different evidence. A taxonomic match does not establish pet safety, local availability or a cultivar’s needs. Follow the citations and review date on the particular care profile. The source page explains the dataset’s license and the size of the curated subset.
Contact & corrections.
For a tool issue or a factual correction, tell us which page you used, what you expected and the relevant source if you have one. Please do not send your whole journal or private files unless they are needed and you choose to share them.
