Table 1.
Comparison of the productivity of the vertical farming system (VFS) and horizontal hydroponic system (HHS)
| Parameter | HHS | VFS | Result |
|---|---|---|---|
| Shoot fresh weight (g) Mean ± SE (n = 40) | 138 ± 6 | 95 ± 6 | P < 0.001b |
| Yield per occupied growing floor areaa (kg FW·m−2) | 6.9 | 95 | VFS/HHS = 13.8 |
| Number of plants per occupied growing floor areaa (plant number m−2) | 50 | 1000 | VFS/HHS = 20 |
a
HHS growing floor area: 0.4 m2, VFS growing floor area: 0.02 m2.
