In order to reap the total health benefits of microgreens, eat them immediately after you harvest them. These little greens loose there nutritional value rapidly after harvest. That is why we encourage growing microgreens in your homes.
They are so simple to grow, and harvested within 10-14 days allow the health benefits to remain high. Once ready for harvest you have up to 2 weeks to harvest as needed. Packaged microgreens seen in stores have already lost much of there nutritional value. Reportedly, nutritional value diminishes hourly.. so even though they look healthy they will not have near the nutrient value as fresh cut.
