I am a newbie. My first liquid culture is showing some growth, but I do not know when it is ready to use. I can't wait to inoculate my first grain to see how it works out. From a different web page I found the following. Signs of growth after one week max, and fully done at week 3 max. Some see growth in under a day and fully done in 3. Once growth has slowed down (done), either use immediately or store in a fridge. How much growth is required to be ready to inoculate grain?
