Logistic growth modelling in plants

... by means of a simple [measure/age] division or should I use some sort of specific formula? (I got this doubt when looking at a formula for an exponential growth model: r = ln (pf / pi) / n , where pf and pi are the final and initial measures [or extreme values] of the variable for every variate ...
