I am growing radicchio from seed for the first time and am worried about its germination.
Should I start the seeds in soil or soak them first? Also, would it be recommended to place the pot under grow lamps indoors during the germination period or only after they have sprouted?
Finally, if I would like 18 plants to grow successfully, how many seeds should I plant? (ie what is the ratio of seed to successful plant)
*Everything will be grown indoors with access to grow lamps at a temperature around 18-22 degrees Celsius
*Any watering/general tips welcomed
