I think it helps.
Thigmomorphogenesis is the response by plants to mechanical sensation (touch) by altering their growth patterns. In the wild, these patterns can be evinced by wind, raindrops, and rubbing by passing animals.
Wind (I use a fan here) is a Morphogenic Stimulus and strengthens stalks by resistance as well as increasing transpiration of the plants by dehydrating the leaf surface.
The transpiration causes rapid mineral and water uptake increasing the thickness of the stem.
Using a fan also helps keep the surface of the soil dry to prevent mold, fungus Gnats and damping off.
