haven ’ t the strength to stay upright , they may fail to get the appropriate light .”
In hydroponics , we want our plants to have sturdy stems at the base to properly support the plant as it grows and develops fruit . Wind is an easily used source of the movement needed to produce a small amount of ethylene or an auxin , and it helps our plants to be adequately strong . However , strength is not our only goal and it ’ s not the most important . We want yield . Too much wind will cause the plant to grow in a manner that does not support this goal . Yet , sometimes we are dealing with plants that won ’ t stand up correctly and may have trouble getting all the light or radiation that we provide . What to do ? Having leaves gently move as a response to soft breezes in the grow area or tent , especially while the plant is young , will generally produce a strong and vigorous plant with a sturdier base . Blasting plants , whether young or mature , with strong wind is going to interfere with crop production . Strong winds will also tend to cause the stomata on the plant leaves to close , reducing CO 2 intake and weakening photosynthesis . Photosynthesis is a critical process for nearly every aspect of plant health and production . Though young plants often develop properly without these gentle breezes , dealing with at least mild wind is natural for most plants . Those that are completely protected and isolated from any movement or breeze at all have an increased propensity to develop some weakness in their stems or base . Hormones produced by this movement will affect other aspects within a plant , too .
