Chadash/Yashan on hydroponics


According to Halacha, does the prohibition of Chadash apply to one of the five grains grown hydroponically or no? Or since it is on hydroponics, do the laws of Yashan/Chadash not apply?




Interesting question. I asked your question to Rav Saul Reichenberg, a leading expert on these topics, and he said that regarding chodosh and yoshon he doesn’t see why there should be a difference between if it is grown in water of in the soil. Therefore it would apply.

Best wishes
