Vinegar is a HERBICIDE it can kill plants ( I use it all the time to kill dandelions). You may best prevent damping off by keeping damp not wet. allow for good air circulation around the plant. allw for adequate light. starting with steril soil & fungal free seed.

I have seen this question before. Where did you read this? It sounds like we've a troll or something. As georgez5il implies, it makes no sense at all.

It makes all kinds of sense, as long as you understand that it's all about dilution rates. Mixing about a tablespoon of household vinegar to a gallon of water will create a misting solution that is inhospitable to damping off and other disorders. Without damaging plant foliage. The use of vinegar at this dilution rate is an excellent way of reducing the pH of water for watering and mixing pesticides, as well.

However, damping off is relatively easy to prevent by paying special attention to the seeding and seedling environment and the germination medium. Plenty of good air circulation is essential, I think. Just as much as a fast draining medium.
