Our first crop is still growing. We're raising saffron indoors in Jonesboro, Georgia, with the first harvest expected in late 2026. Sign up below and we'll tell you when it's in, and publish the analysis that comes with it.

Laboratory tests
Three samples submitted to the University of Georgia Agricultural & Environmental Services Laboratories. Received 8 July 2026, completed 10 July 2026.
S1 — Routine soil test
pH, lime buffer capacity, and Mehlich-1 extraction
| Sample | Lab no. | pH | Ca | K | Mg | Mn | P | Zn |
|---|---|---|---|---|---|---|---|---|
| A | 1265 | 7.39 | 11301 | 2885 | 3316 | 96.7 | 269 | 14.7 |
| B | 1266 | 7.20 | 5890 | 1763 | 1927 | 85.6 | 147 | 21.5 |
| C | 1267 | 7.09 | 8639 | 2926 | 2326 | 86.6 | 563 | 44.3 |
Mehlich-1 extraction, results in mg/kg (ppm). Report No. SO2627.
- Sample A — amended medium, end of cycle
- Sample B — amended medium with microbial inoculant, end of cycle
- Sample C — unamended base medium, unused control
Sample C is the baseline: fresh medium that never held a crop. A and B are the same medium after a full grow cycle, so the differences show what the plants drew down and what the amendments put back. Sample B has been submitted for further analysis — we'll publish those results here when they arrive.
