The contribution from temperature gradients within a plant to convective transport is calculated. Its magnitude depends primarily on the temperature differences in the plant and the radius of the conducting elements; the other quantities affecting it are well‐established physical constants. Assuming a temperature difference in the plant of 1 K and a conductive element radius of 10 −4 m, the speed of convective flow is 0.5 cm h −1 and this is independent of distance.
