Locations and Substrates¶

Locations describe where your plants grow — from your entire garden down to a single pot slot. Substrates define the growing medium. Both concepts form the spatial foundation for all other features in Kamerplanter.

Prerequisites¶

• A Kamerplanter account with at least one tenant (created automatically during onboarding)
• For substrates: at least one location already set up

Understanding the Location Hierarchy¶

Kamerplanter organises locations in a tree structure with three levels:

Site (facility)
  └── Location (area)
        └── Slot (plant spot)

Site is your top-level facility — for example "My Garden" or "Berlin Apartment". At the site level you store the water source, climate zone, and total area.

Location is a concrete area within a site — for example "Grow Tent A", "Raised Bed 1", or "South Balcony". Locations can contain further locations: you can model "House" → "Living Room" → "South Window Sill".

Slot is a single planting spot — for example "Pot 3" or "Row 2, Position 4". Slots are always the bottom level and can be assigned to exactly one plant.

Creating a New Site¶

Step 1: Navigate to Location Management¶

Click Locations in the left navigation. The overview page shows all your sites.

Step 2: Create a New Site¶

Click Add Site (top right). A form opens.

Step 3: Fill in Basic Data¶

Step 4: Configure Water Source (optional, Intermediate and above)¶

If you use tap water or a reverse osmosis system, enter the water values. The system will automatically calculate your EC budget, CalMag requirements, and mixing recommendations.

Tap Water Profile¶

Additional Options¶

• Has RO system: Enable this if you have a reverse osmosis unit. The system will then calculate mixing ratios for tap and RO water.
• Measurement date: Date of the water analysis. Kamerplanter warns you if the analysis is older than 12 months.
• Source note: Free text for the origin of the values (e.g. "City Water Report 2025").

Step 5: Save¶

Click Save. The site appears in the overview.

Adding Locations and Slots¶

Adding a Location Within a Site¶

1. Open a site by clicking its name.
2. In the Locations tab you see the location tree.
3. Click Add Location.
4. Select a location type from the list (see table below).
5. Enter a unique name.
6. Optional: Select a parent location (for nested structures).

Available Location Types:

Adding a Slot Within a Location¶

1. Open a location by clicking its name in the tree.
2. Click Add Slot.
3. Enter a label (e.g. "Pot 1" or "Row A, Position 3").
4. Optional: Enter the capacity (pot size in litres).

Managing Substrates¶

A substrate describes the growing medium in which your plants root. Kamerplanter distinguishes between different substrate types and allows management of substrate batches.

Creating a New Substrate¶

1. Navigate to Locations → Substrates.
2. Click Add Substrate.
3. Select the substrate type (see table).
4. Enter a name (e.g. "Organic Soil Batch March 2026").
5. Optional: Enter pH range, EC value, and capacity.

Available Substrate Types:

Assigning a Substrate to a Slot¶

1. Open the desired slot.
2. Click Assign Substrate.
3. Select an existing substrate from the list.
4. The substrate is now linked to this slot.

Preparing a Substrate for Reuse¶

After completing a growing cycle you can prepare a substrate for reuse:

1. Open the substrate in the detail view.
2. Click Prepare for Reuse.
3. The system checks pH standard deviation and EC drift from previous use.
4. If the drift is too large a warning appears — in this case, new substrate is recommended.
