There are not really any “Recipes” yet established beyond those that can be actuated directly onto the V2, which is I believe Arugula and basic leafy greens. I will say that right now, the V2 you cannot obtain lights or a chiller for based on the BOM. So keep that in mind before starting to order parts.
All sorts of people on the forums are growing peppers, strawberries, tomatoes, mushrooms. I haven’t seen any rice, but I’m extremely interested @house might be as well. @wsnook has some good insight into other projects being done internationally that may be a bit more up your alley. Also, @BioLumo is doing all sorts of stuff with Corn, Maize, and other outdoor crops as well.
On your other post, you mentioned being interested in a simpler food computer. Check out the $300 Food Computer (basic growth chamber with hydroponics, LED lighting, and some temperature control via a Raspberry Pi) as a good place to start, if nothing else you may be interested in the materials we chose as they were designed for being cheap/effective.
