Rather, length is determined dynamically as ~ N k τ + (10)
It seems a little odd to posit an attractive force in the derivation (Equation (12)) and then ignore/dismiss it in the numerics (“… in reality the attractive force does not really exist, trichomes only cohere after they have come into contact” page 12). Clearly, this is done to (quite reasonably) avoid modeling steric interactions with hard bodies. It was a little distracting to think that sticky adhesion was decaying like 6 ( ) h Θ . Perhaps note after Equation (12) that the attractive force decreases to zero at a finite distance in the numerics.
