Flood Irrigation Date: 2/4/2009
steadyGROWpro vs steadyGROWpro - H+ (inches)
| steadyGROWpro | steadyGROWpro - H+ |  |

| Immediate | 1.5" | 2.625" (FULL) | |
| 1 Hour | 1" | 2" | |
| 8 Hour | 0.75" | 1.5" | |
| 24 Hour | 0 | 0.75" | |
| 48 Hour | 0 | 0.1" | |
| *** All Figures Include Water Weight Only *** | |||
| SteadyGROWpro blocks were sub irrigated with a 3" flash flood of water. Blocks did not rest in water for an extended period of time, and the steadyGROWpro blocks were not irrigated again for the duration of the test. |

***All studies conducted by Purdue University Horticulture Department in conjuntion with Pawan Srivastava - Ph.D.
***All water column studies used a 4" x 4" x 2⅝" block of steadyGROWpro media
