Broccoli microgreens contain up to 10 times more sulforaphane than mature broccoli, and 51mg of vitamin C per 100g of fresh weight, according to published nutrition data.
Most microgreens growers fail because they grow first and sell second. Here is what a profitable operation looks like: committed buyers first, equipment second.
Choosing the right microgreens involves analyzing regional demand, growing conditions, and profit margins. Key activities include researching local preferences, starting with manageable varieties, and planning crop rotations.

Microgreens are rich in phytonutrients, antioxidants, and vitamins such as C, E, and K, which are pivotal in enhancing immune function. These bioactive compounds modulate cellular immune responses, fortifying the body’s defense mechanisms against pathogens. Incorporating microgreens into one’s diet can thus be a strategic approach to bolstering immune health.
Microgreens are becoming a center of many college projects and a much-appreciated addition to school cafeterias. Why is it happening, and how can you set up your own college micro-garden?
