Start seeds in a greenhouse or protected indoor area on potting mix or soilless medium in shallow trays or 20-row flats. Follow standard brassica family germination guidelines. Broadcast seeds thickly with 1/8 to 1/4 inch spacing between seeds, press firmly into the media for maximum soil contact, and cover lightly with sowing mix, vermiculite, or a humidity dome. Maintain consistent moisture and moderate temperatures typical for microgreen production.
Harvest Rainbow Sprinkles Mix microgreens when they reach 16-25 days from sowing, typically once the first true leaves have expanded beyond the cotyledons and the shoots are 1-2 inches tall. Cut just above soil level using clean scissors or a sharp knife. Wash the microgreens before serving, and use them immediately for best flavor and nutrition, though they will keep under proper storage conditions.

“Rainbow Sprinkles Mix represents Johnny's Selected Seeds' approach to creating practical tools for modern microgreen growers. By combining beet and chard genetics, the mix leverages the proven vigor and nutritional density of both Beta vulgaris subspecies, offering growers a curated blend rather than a single varietal focus. This cultivar emerged from the seed industry's growing recognition that microgreens demand different selection criteria than full-size vegetables, favoring rapid germination, uniform height, and visual appeal at the seedling stage.”
