Sowing dossier, one field
₹699$9
One field, one season. The full staged plan, water balance, seed rate, break-even yield, the sensitivity table and the provenance appendix, as PDF and JSON.
The agronomy is the product.
The control software is free and runs on your own board, on your own network, and phones nobody. The articles are free and always will be. What is worth paying for is the part that took a season to validate: staged recipes with the reasoning behind every band, and the desktop application that reads the logs your rooms produce.

What happens after you pay
- A receipt and your download links arrive by email, at the address you pay with, usually inside a minute and always inside an hour.
- Files are yours to keep. Download them again whenever you like from the downloads page — enter the same email address and a fresh link is sent. There is no account and no password to lose.
- Licences are signed files, 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.
- Hardware ships from India by courier. The lead time on each card is working days from the day the payment clears.

What "one payment" means here
You keep it
There is no subscription and nothing expires. The files are yours, downloadable whenever you want them, using the email address you paid with. No account, no password, nothing to lose access to.
It is version 1
You get everything published under version 1, including species added to it later. A future version 2 will be a separate purchase with an upgrade price for owners. Saying so now is the only honest way to sell a one-time price for something that is still being worked on.
The application keeps running
A Pro licence includes twelve months of updates. After that date the application does not stop, expire or nag — it simply stops accepting builds newer than your licence. What you installed keeps working for as long as the machine does.
What stays free
Every article on this site, permanently. The node build guide, the bill of materials and the wiring diagrams, permanently. Somebody reading that parts list is deciding whether to spend nine thousand rupees on hardware, and that is not the moment to ask them for two hundred more.
There is no article paywall on this site and there will not be one. It cannot be enforced in a browser, it falls hardest on the readers who read most, and it would put at risk the organic traffic that every sale here depends on.
