For this case, the first thing we should do is define a variable.

The formula that models this problem is given by:

$x = \frac initial\ height-final\ height {initial\ height} * 100$

Substituting values we have:

$x = \frac 6-12 {6} * 100$

Rewriting:

$x = \frac -6 {6} * 100\\x = \frac {6} {6} * 100\\x = 100\%$

Answer:

The percent increase in the height of the plants is 100%
