The whole recipe library. Two dollars.
The software is free and always will be — it runs on your own board, on your own network, and it does not phone anybody. What is worth paying for is the agronomy: six species staged from spawn run to last flush, every band with the reasoning behind it, versioned so your second season can correct your first.

Licences are signed files keyed to your hardware, checked offline, with a grace period. There is no activation server to go down and nothing to phone home. The check lives in one module with one boundary and is deliberately nowhere near the control path — a licensing bug must never be able to hold a crop hostage.
Hardware
You can build the node yourself for about Rs 9,190 in parts — the full list, with the reason for every choice, is on the sizing page and always will be. Buy it assembled if you would rather not wire mains.
Node kit, unassembled
₹9,900
Every part on the list, boxed, with the enclosure pre-drilled and the barrier fitted. You do the wiring. Firmware pre-flashed.
Node, assembled and tested
₹15,500
Built, wired, earthed, fused and soak-tested for seventy-two hours. Mains section reviewed by a licensed electrical engineer.
Tent kit — one room
₹34,000
Node, 150 mm inline fan, 1.5 L/h fogger, circulation fan, LED strip and ducting. Sized for a room around 22 m³ with 100 kg of substrate.
Prices are indicative and dated to the parts list. The CO2 sensor is a third of the node cost and moves with the semiconductor market; if it moves, this page moves with it rather than quietly absorbing the difference.
Add Claude to your controller
Every screen here computes its own numbers and always will. But once you have a simulator verdict, a stage summary and three weeks of decision log, the useful next step is a second opinion — something that reads all of it and tells you which single finding is about to cost you a flush.
That is what the Claude API is for here. Bring your own key, switch it on, and the advisor appears on the simulator and on every recipe. It is shown only figures this module already computed and is forbidden from inventing new ones — it ranks and explains, it never sets a target. And it is never in the control loop: your room keeps running with the key removed, the internet cut, and this site switched off entirely.
You pay Anthropic directly for what you use. We take nothing, see nothing, and store the key on your own site.
