*Update 11 October 2018: Please note that MIT OpenAg at the Media Lab has paused research on these versions, and while their build resources remain available on our wiki page and GitHub, MIT OpenAg can’t currently support community members’ individual builds of these versions. Let us know if you're building one of these versions, or have modified the build on this Google Form. For more details, see this community forum post.

Please see the Personal Food Computers page for info on all versions of the OpenAg™ PFC.

The OpenAg™ Personal Food Computer v2.1 is an evolution of the PFC v2.0. This release includes a new light panel and updated software.

The updated software is the latest release of the openag_brain v1.0.0. It has several updates and many bug fixes.

For more details on testing done with the v2.1 updates, check out Reliability Test Grow log with notes, problems, pictures and results.

Note: The v2.1 LED light panel was custom-made by Tim (one of our awesome OpenAg engineers) and uses red/white/blue GE LED's. Some users have hacked their PFC's to use an off-the-shelf grow light panel. OpenAg is working on finding a light and supplier that fit system requirements and can be purchased online as a single unit.
