Plain answers about what they are, why people eat them, how to keep them, and how we grow ours in Littleton. No hype — just the useful bits.
What are microgreens?
Microgreens are young seedlings of vegetables and herbs, usually harvested when the seed leaves (cotyledons) are open and the first true leaves are just coming in — often about 1 to 3 inches tall, roughly 7 to 21 days after sowing, depending on the crop.
They're different from sprouts, which are germinated seeds eaten whole (seed, stem, and root), often grown in water with little or no light. They're also different from baby greens, which grow longer (often a few weeks more) until true leaves are fully developed and plants are taller. With microgreens, you eat the cut stem and leaves; the roots stay in the tray.
Why eat them?
People reach for microgreens for flavor, color, and texture — a small handful can brighten a plate. On nutrition, a well-known 2012 study by USDA Agricultural Research Service and University of Maryland researchers measured vitamins and carotenoids in 25 commercial microgreen varieties. Levels varied a lot by crop, and on average the young greens showed higher concentrations of several vitamins and carotenoids than the mature leaves of the same plants (compared with USDA nutrient data). Growing, harvest, and handling can change those numbers, so think of microgreens as a flavorful way to add variety to vegetables — not a medical treatment.
How to store and use
Keep microgreens cold and dry in the fridge (about 40°F / 4°C or below). Leave them in their container or a breathable bag; don't wash until you're ready to eat. Ours are sold unwashed on purpose — rinse gently under cool running water right before use, then pat dry. (Soap or produce washes aren't recommended for fresh greens.)
Shelf life depends on variety and how they're handled; many people use refrigerated microgreens within several days to about a week or so while they still look fresh and crisp. Trust your eyes and nose — if they wilt, smell off, or look slimy, compost them.
Easy ideas: toss into salads, tuck into sandwiches and tacos, scatter over eggs, use as a garnish, or blend into a smoothie. A little goes a long way.
How we grow
Each variety gets its own tray. We grow in a soil-based mix, give the seedlings light and care, then harvest with a single cut just above the medium. No mixed blends in the pack — you get one variety at a time so the flavor stays clear.
Soil health sits at the center of the work. My day job is with a soil-sample prep team, and that background keeps me focused on living soil: organic matter, careful handling, and closing loops where we can. We're building toward a composting and worm-castings (vermicompost) loop — turning kitchen scraps and cardboard into castings that feed the next round of trays and garden beds. Live worms and bagged castings are planned for later; see Coming soon below.
For chefs
Single-variety, unwashed microgreens give kitchens control: you rinse when you're ready, so greens stay drier in storage and you decide the final wash. Distinct varieties mean predictable flavor and color for garnish, salads, and plating — without a pre-mixed blend you didn't ask for.
We're a small Littleton grow, still finishing local licensing before retail orders. Restaurant and chef inquiries are welcome now so we can plan trays. Reach out with what you use and roughly how often.
Quick FAQ
Are your microgreens washed?
No. They're sold single-cut and unwashed. Keep them cold and dry, then rinse under cool running water right before you eat or plate them.
Do you sell mixes or juice?
No. We grow and sell single varieties only — no blended mixes and no juice.
Are you certified organic?
No. We grow with a soil-health focus and carefully chosen inputs, but we don't claim organic certification for Greg's Grateful Greens.
How long do they keep?
It varies by variety and storage. Keep them refrigerated and dry, and plan to use them while they still look and smell fresh — often within several days to about a week. When in doubt, compost.
Can restaurants order now?
We're launching soon and not yet taking regular orders, but we are collecting chef and restaurant interest so we can plan. Email is the best way to start.
