Calculated maximum edible growth rates of tested species in highest yielding media (highest yielding for dry mass)_ Calculations use a 28 day growth period and a pillow with external area of 0_015 m2_ Mass is an average of three pillows with two plants per pillow_ Radish data are for tap root mass while other data are for shoot mass_
| Plants | Edible Growth Rate | Media | |
|---|---|---|---|
| (g FM/m2/day) | (g DM/m2/day) | ||
| Cabbage | 42.9 | 8.0 | 1:1 Fafard#2: arcillite |
| Chard | 24.3 | 4.4 | 7:3 Fafard#2: arcillite |
| Lettuce | 38.3 | 3.5 | 1:1 Fafard#2: arcillite |
| Radish | 44.5 | 4.6 | 7:3 Fafard#2: arcillite |
| Snow pea | 21.8 | 4.4 | arcillite |
Average shoot dry mass (g) (shoot and tap root for radish) per pillow of five species grown in four media types_ Data are averages for three pillows, with pillow values the sum of the dry mass of two plants_ Means between plant species within a media type with different letters are significantly different at P<0_05_ Asterisks indicate means within a species that are significantly different between media types (P<0_05)
