Frequently asked questions

Yes. Root & Relay hardware pre-orders are now available through the Root & Relay Shop. The current expected delivery target is the last week of December 2026. Delivery timing is an estimate and may change as fulfillment details are finalized. If the communicated delivery period passes without shipment, the affected hardware pre-order will be eligible for a refund.

The current sensor prototype connects to a home Wi-Fi network. Internet access is needed for cloud services and live Karpos answers. Outdoor range, connection reliability, and behavior during outages are being tested; we are not promising an offline service or a specific range.

The production design uses a battery with solar charging. Final battery capacity, charging requirements, and runtime in shade or cloudy weather are being tested. We will publish validated specifications before orders open.

A sensor measures conditions at its placement, not every part of a garden. Separate beds, containers, soils, or watering areas may need separate sensors. Coverage and recommended placement are being tested, so there is no confirmed sensors-per-square-foot rule yet.

Current prototypes collect soil moisture, electrical conductivity (EC), root-zone temperature, and UV readings. The sensor does not take photos; the camera has been removed. EC is not a direct measurement of individual nutrients. Production specifications and outdoor durability are still being tested.

Yes. You can upload photos from your device so Karpos can use the selected image as context when helping you assess what is happening in your garden. The sensor does not take photos automatically. Photo uploads are included in the Free plan; personalized Karpos questions are part of Premium.

Free includes real-time sensor data, photo uploads, garden notes, and general growing guides. Sensor readings require compatible Root & Relay hardware and connectivity. See the plan comparison for the full details.

For the December 2026 launch, Garden Plus will be $4.99 per month or $49.99 per year and adds a personalized Karpos Daily Recap to everything in Free. Premium will be $9.99 per month or $99.99 per year and includes everything in Garden Plus, plus personalized questions for Karpos and the advanced garden Timeline. Subscriptions will be purchased through the applicable app store, not on this website. See the plan comparison.

Garden Plus includes everything in Free, plus a personalized Karpos Daily Recap using available garden, sensor, crop, and weather context. You can ask to refresh the recap. See the plan comparison.

Premium includes everything in Garden Plus, plus personalized questions for Karpos and the advanced garden Timeline. Personalized answers use the garden details, location, readings, weather, and any image you select that are available to your account. Missing data cannot be inferred as a live measurement.

Yes. Your first qualifying purchase of new Root & Relay hardware includes one complimentary 30-day period of Premium access from the initial account setup. A multi-sensor package does not add multiple months, and separate sensor purchases do not stack or restart the complimentary period. After that period, continuing Premium access will follow the subscription options and terms presented in the app.

Karpos provides recommendations. It does not automatically apply its advice to controller or irrigation settings. You review the recommendations and decide what to change.

Supported phone versions, launch regions, and environmental limits are still being tested. Public guides give general growing information; personalized Karpos guidance uses your available location and garden context, not a single default growing zone.
