Broccoli microgreens contain up to 100 times more sulforaphane than a full head of mature broccoli. That's not a typo. One hundred times. And you can grow them on your kitchen counter in about seven days, with zero gardening experience, for less than the price of a coffee.
Microgreens are the tiny, nutrient-packed seedlings of vegetables and herbs, harvested when they're just 1-3 inches tall. They've gone from restaurant garnish to genuine superfood in the last few years, and for good reason. They're faster to grow than any other food crop, they grow year-round indoors, and they cost a fraction of what stores charge when you grow them yourself.
Store-bought microgreens run $25-50 per pound. Growing your own? About $2-5 per tray. The math is absurd. And the growing process is so simple that calling it "gardening" feels generous. You're basically putting seeds on a wet surface and waiting a week.
Here's exactly how to grow microgreens at home, which varieties to start with, and the best kits and supplies to get you harvesting in seven days.
Key Takeaways
- Microgreens are ready to harvest in 7-14 days and contain 4-40x more nutrients than mature plants
- You can start growing for as little as $6.99 with a basic tray and seeds
- The HAMAMA kit ($49.95) is the easiest option for beginners — just add water once and harvest in 7 days
- Best beginner varieties: radish, broccoli, sunflower, pea shoots, and wheatgrass
- Growing your own saves 80-90% compared to store-bought microgreens at $25-50/lb
- No garden, no yard, no experience needed — a kitchen counter and a window are enough
Why Microgreens Deserve a Spot in Your Kitchen
Microgreens aren't sprouts. Sprouts are germinated seeds eaten root and all, usually grown in water. Microgreens grow in soil or a growing medium, develop their first true leaves, and you cut them at the stem. They're more flavorful, more nutritious, and way more versatile in cooking.
The nutrition density is what makes microgreens genuinely special. A 2012 study in the Journal of Agricultural and Food Chemistry analyzed 25 varieties and found microgreens contained 4 to 40 times higher concentrations of vitamins C, E, and K compared to their mature counterparts. Red cabbage microgreens had 40x more vitamin E and 6x more vitamin C than a full-grown red cabbage.
But the practical benefits matter just as much as the nutrition:
- Speed. Most microgreens are harvest-ready in 7-14 days. Compare that to 60-90 days for a head of lettuce or 80+ days for broccoli.
- Space. A single 10x20 inch tray on your countertop is all you need. No yard, no balcony, no garden bed.
- Year-round growing. Microgreens don't care about seasons. Grow them in January in Alaska or August in Arizona. Same result.
- Cost savings. At $25-50/lb retail, microgreens are one of the most expensive produce items by weight. Growing your own drops that to $4-10/lb.
- Zero experience needed. If you can spread seeds and add water, you can grow microgreens. It's the most beginner-friendly food you can produce at home.
How to Grow Microgreens: Step-by-Step Guide
Whether you're using a kit or going the DIY route with trays and seeds, the process follows the same basic steps. Here's the complete walkthrough.
1 Soak Your Seeds (Optional but Recommended)
Larger seeds like sunflower, pea, and wheatgrass benefit from an 8-12 hour soak in room temperature water before planting. This kickstarts germination and improves your germination rate. Smaller seeds like broccoli, radish, and arugula don't need soaking — they germinate quickly on their own. If you're using a kit like HAMAMA with pre-seeded quilts, skip this step entirely.
2 Prepare Your Tray and Growing Medium
Fill a shallow tray (standard 1020 size works perfectly) with about 1-2 inches of pre-moistened growing medium. You can use potting soil, coconut coir, or hemp mats. The medium should be damp but not waterlogged — think wrung-out sponge. Level the surface so it's flat and even. If you're using a kit, this step is usually done for you.
3 Spread Seeds Densely and Evenly
This is where microgreens differ from regular gardening. You want thick, even coverage — seeds should be close together but not piled on top of each other. For small seeds like broccoli, aim for about 10-12 seeds per square inch. For larger seeds like sunflower, place them edge to edge in a single layer. Mist the seeds lightly with a spray bottle after spreading.
4 Cover and Blackout (3-4 Days)
Place a second tray (or a damp paper towel covered with a lid) over the seeds to block light completely. This is the blackout phase. It forces the seedlings to stretch upward searching for light, which gives you taller, more tender microgreens. Keep them in a room-temperature spot (65-75°F). Mist once daily during blackout to keep the medium moist. After 3-4 days, you'll see pale yellow seedlings pushing up against the cover.
5 Uncover and Add Light (3-4 Days)
Remove the cover and move the tray to a spot with indirect sunlight or under a grow light. The pale seedlings will turn green within 24-48 hours as they start photosynthesizing. Water from the bottom by pouring water into a lower tray and letting the growing medium absorb it — this prevents mold and keeps the leaves dry. Give them 12-16 hours of light daily.
6 Harvest and Eat
When your microgreens are 1-3 inches tall and have developed their first set of true leaves (the second pair of leaves after the initial seed leaves), they're ready. Use clean scissors or a sharp knife to cut the stems just above the soil line. Rinse gently, pat dry, and eat immediately for maximum nutrition and crunch. Store unwashed microgreens in a sealed container with a paper towel — they'll keep for 5-7 days in the fridge.
5 Best Microgreen Varieties for Beginners
Not all microgreens are created equal. Some germinate in 2 days and basically grow themselves. Others are finicky and mold-prone. Start with these five and you'll build confidence fast.
1. Radish Microgreens
The fastest and most forgiving variety. Ready to harvest in 5-6 days. They have a pleasant, mildly spicy kick that works on everything from tacos to sandwiches. High germination rate, vigorous growth, almost impossible to mess up. If you only grow one thing, grow radish.
2. Broccoli Microgreens
The nutrition powerhouse. Contains up to 100x more sulforaphane than mature broccoli — a compound linked to cancer prevention, reduced inflammation, and improved heart health. Mild, slightly bitter flavor. Ready in 7-10 days. Easy to grow, just slightly slower than radish.
3. Sunflower Microgreens
The most satisfying to eat. Crunchy, nutty, and substantial — these feel like actual food, not just a garnish. They're larger than most microgreens, with thick stems and a fresh, slightly sweet flavor. Soak seeds 8-12 hours before planting. Ready in 10-12 days.
4. Pea Shoots
Sweet, tender, and beautiful on the plate. Pea shoot microgreens taste like fresh snap peas and add a gorgeous visual touch to any dish. They grow tall and curly with tendrils. Soak seeds overnight. Ready in 10-14 days. Great in stir-fries, salads, and as a side dish on their own.
5. Wheatgrass
The juicing classic. Wheatgrass microgreens are primarily used for juicing and smoothies rather than eating whole. Rich in chlorophyll, vitamins A, C, and E, and a range of minerals. Fast growing (7-10 days), tolerant of mistakes, and produces dense, vibrant green trays. You'll need a wheatgrass juicer or a powerful blender to use it.
5 Best Microgreen Kits and Supplies
You can grow microgreens with nothing more than a takeout container, paper towels, and seeds from a health food store. But the right kit makes everything easier, cleaner, and more consistent. Here are the five best options from beginner to advanced.
HAMAMA Microgreens Kit
HAMAMA made microgreens genuinely foolproof. Their system uses pre-seeded "Seed Quilts" — you place a quilt in the tray, add water once, and walk away. That's it. No measuring seeds, no soaking, no misting, no soil. The seeds are already evenly distributed in a biodegradable mat with the perfect growing medium built in. You add water to the tray, drop in the quilt, and harvest in about 7 days. The kit includes one ceramic-coated tray and three Seed Quilts (typically broccoli, radish, and a salad mix). It's the absolute best starting point for anyone who wants microgreens without any guesswork.
Pros
- Truly foolproof — add water once, harvest in 7 days
- No soil, no mess, no daily maintenance
- Pre-seeded quilts eliminate seed measuring
- Attractive tray looks good on any countertop
- Wide variety of Seed Quilt flavors available
Cons
- Ongoing cost for Seed Quilts ($5-6 each)
- Limited to HAMAMA's quilt varieties
- Smaller growing area than standard 1020 trays
- Can't use your own seeds in the system
Mountain Valley Mini Kit
If you want to try microgreens before committing to a full setup, this is your entry ticket. For less than seven dollars, you get a basic growing tray and enough seeds to produce your first harvest. It's bare-bones — no fancy growing medium, no pre-seeded quilts, no bells or whistles. But that's the point. It lets you experience the entire growing process, see how fast microgreens develop, taste them fresh, and decide if you want to scale up. Think of it as a $7 experiment that could change how you eat.
Pros
- Cheapest way to start at $6.99
- Low risk — test before you invest
- Teaches the full growing process hands-on
- Small footprint, fits anywhere
Cons
- Very basic — no growing medium included

- Not a long-term solution for regular growing
InGarden LED Hydroponic Kit
For those who want the premium experience, InGarden combines microgreen growing with sleek, modern design. The kit includes a full-spectrum LED grow light, an automatic watering system, and a beautifully designed ceramic base that looks like a piece of home decor rather than a growing setup. It uses organic seed pads (similar to HAMAMA's quilts) and grows microgreens hydroponically — no soil at all. The LED light means you don't need a sunny windowsill, and the automatic watering means you don't need to remember anything. It's the Apple product of microgreen kits.
Pros
- Full-spectrum LED eliminates need for sunlight
- Automatic watering system — truly hands-off
- Beautiful design fits high-end kitchens
- Organic, pre-seeded growing pads
- Consistent results regardless of location
Cons

Cost Breakdown: DIY vs Kit vs Store-Bought
Let's talk numbers. Microgreens are one of those rare things where growing your own is dramatically cheaper than buying. Here's how the math works.
Store-Bought Microgreens
- Retail price: $25-50 per pound
- A typical 2 oz clamshell at the grocery store costs $3-5
- If you eat microgreens 3-4 times a week, that's $12-20/week or $50-80/month
Kit Growing (HAMAMA)
- Initial kit: $49.95 (includes tray + 3 Seed Quilts)
- Ongoing Seed Quilts: $5-6 each
- Each quilt produces roughly 4-6 oz of microgreens
- Monthly cost (2 grows/week): ~$40-48 in quilts
- Cost per pound: roughly $10-15
DIY Growing (Trays + Seeds)
- Bootstrap Farmer trays (10-pack): $25-30 (one-time, reusable for years)
- True Leaf Market seeds: $20-25 (enough for 20-40 trays)
- Growing medium (coconut coir brick): $10-15 (lasts 15-20 trays)
- Total startup: $55-70
- Ongoing cost per tray: $1-3 (seeds + coir)
- Each tray produces 6-10 oz of microgreens
- Cost per pound: roughly $2-5
The bottom line: DIY microgreen growing costs roughly $2-5 per pound compared to $25-50 per pound at the store. That's an 80-95% savings. Even with the HAMAMA kit's ongoing quilt costs, you're still saving 50-70% over store-bought. The trays-and-seeds approach breaks even after just 2-3 harvests.
7 Common Microgreen Mistakes (and How to Avoid Them)
Microgreens are forgiving, but a few mistakes can ruin a tray. Here's what trips up beginners and how to fix it.
- Overwatering. The number one killer. The growing medium should be moist, not soggy. If you can squeeze water out of it, it's too wet. Excess moisture leads to mold, which kills your tray. Switch to bottom watering after the blackout phase to keep leaves dry.
- Seeds too thick or too thin. If seeds pile up on top of each other, you get tangled, weak stems and mold. If they're too sparse, you get a patchy tray with low yield. Aim for dense, single-layer coverage. Practice makes this intuitive.
- Skipping the blackout phase. The blackout period is what gives microgreens their height and tenderness. Without it, you get short, stubby seedlings that are hard to harvest. Cover them for 3-4 days, even if it feels wrong.
- Harvesting too late. Once microgreens develop their second set of true leaves, they start getting tough and bitter. The sweet spot is right after the first true leaves fully open. Waiting "just one more day" often means worse flavor.
- Using old or low-quality seeds. Seeds older than 2-3 years have significantly lower germination rates. Buy from reputable suppliers like True Leaf Market and store seeds in a cool, dry place. Cheap seeds from random sources often produce disappointing results.
- Not enough airflow. Stagnant air promotes mold. After the blackout phase, make sure your trays have some air circulation. You don't need a fan — just don't seal them in a cabinet. A kitchen counter near normal activity provides plenty of airflow.
- Giving up after one bad tray. Your first tray might not be perfect. That's fine. Adjust your seed density, watering, and blackout timing based on what happened. By the third tray, you'll have the rhythm down and every grow will be consistent.
