Plants not growing.

For some reason, my plant (rice) will not grow. I have used the most popular tutorial, and it still won't work. It is a non-crop plant so it should grow on any regular block that plants can grow on. Here is a recreation of my code with text:

Event trigger - triggered by external call or when (global trigger): [no additional trigger]

Set number (Local: GrowRate) to: Random [0, 1] * 100

[If] Get number (Local: GrowRate) ≤ 5

[do] Place (riceplantstage2) at x [x] y [y] z [z]
