Hydroponic Crop Library v1
Every crop profile in version 1, and every one added to v1 after you buy.
$39
BuyThe software is free. The agronomy is not.
The control core, every interlock, every fail-safe and the simulator are free and stay free — they run on your own board, on your own network, and they do not phone anybody. What is worth paying for is the part that took somebody a season to learn: the bands, the phases, the steering curves and the drivers that have actually been on a bench with the hardware.

Buy the pairNode build guide, BOM and wiring diagrams
How to build the controller, what every part is for, and the electrical safety section that is not optional. Free, and staying free — somebody reading the wiring diagram is deciding whether to spend twenty-two thousand rupees on hardware, and charging them at that moment would be the most expensive charge this site could make.

Read itLicences are signed files keyed to your hardware, checked offline, with a grace period. There is no activation server to go down and nothing phones home. The check lives in one module at one boundary and is deliberately nowhere near the control path — a licensing bug must never be able to hold a crop hostage.
Rupee and dollar prices are chosen for their own markets rather than converted from one another. Nothing here converts a currency, which also means no exchange-rate feed and no rounding drift.
