Cauliflower can be grown indoors, but it requires a lot of light and space. You can start cauliflower seeds indoors about 6-8 weeks before the last frost date in your area. The ideal temperature for growing cauliflower is between 60-75°F. You can grow cauliflower indoors in a container or a hydroponic system. However, you need to ensure that the soil is rich in organic matter and the plant gets enough water and nutrients. Keep in mind that cauliflower takes a long time to grow from seed to harvest, so it requires patience and care.
