WebWe investigated five seed densities ranging from 7 to 21 seeds per square inch, which correlated to seed weights of 2.5 to 7.4 g/tray for arugula; 2.9 to 8.6 g/tray for mizuna; and 2.8 to 8.4 g/tray for mustard. For all three cultivars, harvested fresh weight (FW) increased as seed density increased from seven to 21 seeds/ tray (Figure 2). WebVPD is calculated using temperature and relative humidity. A general VPD range for a greenhouse is from 0.45 kPa to 1.25 kPa. The higher the VPD, the drier it is in the greenhouse. The lower the VPD, the more moisture is present. At the upper limit of the VPD range, the crop may not be able to keep up with transpiration demand.
