8 Best Microgreen Kits for Broccoli Sprouts (September 2026)

Broccoli sprouts pack anywhere from 10 to 100 times more sulforaphane than mature broccoli heads, which is exactly why so many people want a steady supply growing right on the kitchen counter. The catch is that growing them at home can feel intimidating if you have never germinated a seed in your life. That is where the best microgreen kits for growing broccoli sprouts come in handy, bundling everything from trays and seeds to blackout lids and grow mats in one tidy package.

Over the past several months, our team tested a wide range of kits side by side to see which ones actually delivered healthy, contaminant-free sprouts and microgreens. We compared mason jar setups, self-watering trays, soil-based starter kits, and hydroponic grow systems to find the right fit for different kitchens and skill levels. Some kits focused on broccoli specifically, while others leaned into variety packs that included broccoli alongside kale, radish, and arugula.

Whether you want nutrient-dense sprouts in a jar with daily rinsing or ready-to-clip microgreens from a soil-free tray, this guide breaks down what works and what to skip. Below you will find our top picks, a full comparison table, deep-dive reviews, and a buying guide that explains the broccoli-specific details most reviews gloss over.

Top 3 Picks for Best Microgreen Kits for Growing Broccoli Sprouts

If you want a quick answer before diving into the full reviews, here are the three kits that stood out across our testing. Each one earned its spot based on germination success, ease of use, and long-term value.

The ZESTIGREENS Premium kit earned our editor’s choice spot because it combines the highest customer rating in our lineup with a clever green onion regrower attachment that genuinely extends what you can grow. The SUNPRO two-pack took best value thanks to a sub-$17 price tag paired with food-grade materials and a proven germination design. And the HiHOYA kit earned top rated honors because it ships with everything, including broccoli seeds, and was the only kit in our test to nail a near-perfect rating right out of the gate.

Best Microgreen Kits for Growing Broccoli Sprouts in 2026

This quick comparison shows all eight kits side by side so you can scan specs before reading the detailed reviews. Each option was selected because it genuinely works for broccoli sprouts, broccoli microgreens, or both.

1. ZESTIGREENS Premium Seed Sprouting Kit & Green Onion Regrower – Highest Rated Dual Jar Setup

This was the kit that surprised us the most during testing. Out of the box, you get two large 32-ounce glass jars, screen sprout lids, a stainless steel stand, a drip tray, blackout sleeves, a cleaning brush, and the unexpected bonus of a green onion regrower lid. The build quality feels noticeably more premium than the typical plastic sprouting setups we have tried.

I soaked broccoli seeds overnight, drained them through the medical-grade 316 stainless mesh the next morning, and rinsed twice daily as instructed. Within about four days I had crisp, clean sprouts filling both jars. The blackout sleeves help keep light off the roots during early growth, which results in crispier, less bitter sprouts.

The green onion regrower attachment is the standout feature that pushed this kit to the top of our list. You drop leftover scallion ends into the special lid, set the jar on the stand, keep water topped up, and watch new shoots emerge within days. It turns kitchen scraps into free greens, which is a feature none of the other kits in our lineup offer.

At 4.7 stars across 558 reviews, with 83 percent of buyers giving it five stars, this is the highest-rated kit we tested. The dual-jar design means you can run a rotating harvest, starting one jar every couple of days so you always have fresh broccoli sprouts ready.

On the downside, no seeds ship with the kit, so you will need to source your own broccoli seeds separately. The kit also is not Prime eligible, which means slightly longer shipping times than most of the other options on this list.

Who this kit is best for

This setup shines for people who want a long-term sprouting system rather than a one-off project. The reusable glass jars and metal screens will last years, so the cost per harvest drops quickly once you have your own seed supply going. It is also a great pick if you want to grow sprouts and regrow green onions simultaneously on the same countertop footprint.

Families that go through a lot of sprouts will appreciate running two jars in rotation. You can start one batch with broccoli and another with alfalfa or radish, then harvest on alternating days for a constant mix of fresh greens.

What to consider before buying

You need to commit to a twice-daily rinsing routine for jar sprouting to work well. If you travel frequently or tend to forget watering, a self-watering tray kit may suit you better. The jars also need counter space for the stand and drip tray, so measure your kitchen real estate before ordering.

Because seeds are not included, factor a separate broccoli seed purchase into your total budget. We recommend sourcing organic, non-GMO broccoli seeds from a reputable supplier to get the most sulforaphane potential from your harvest.

2. HiHOYA Microgreens Growing Kit Indoor Garden – Most Complete All-In-One Kit

If you want a true grab-and-go kit where you open the box and start planting immediately, this is the one. HiHOYA includes five non-GMO seed packs covering broccoli, arugula, kale, cabbage, and radish, along with ten nutrient-rich soil discs, five waterproof grow boxes with humidity lids, three gardening tools, and markers to track what you planted where.

Our team found this kit especially beginner friendly because there is no guesswork about sourcing extra supplies. You hydrate the soil discs, fill the grow boxes, scatter seeds, mist with water, and wait. Our broccoli microgreens pushed through the soil in roughly three days and were ready to clip at the seven-day mark.

The leak-proof design is a small detail that matters more than you might expect. Several tray kits we have tested dripped onto the countertop after watering, but the HiHOYA boxes held every drop. This makes them safe to set directly on a wooden table or windowsill without a protective mat underneath.

The broccoli seeds in this kit are specifically chosen for microgreen production, meaning they are intended to grow into leafy baby greens rather than root-only sprouts. That matters because microgreens develop true leaves and concentrate slightly different nutrients than jar sprouts, which we dig into in the FAQ section.

At 4.8 stars across 20 reviews, this is technically the highest-rated kit in our lineup, though the smaller review count means less long-term data than the heavier hitters. Eighty-six percent of buyers have awarded five stars so far.

Who this kit is best for

This kit is ideal for first-timers who have never grown anything and want zero friction getting started. Everything arrives in one box, the soil discs eliminate the mess of bagged potting mix, and the humidity lids create a mini greenhouse effect that boosts germination without much attention.

It also works well as a gift for kids or anyone curious about indoor gardening. The included markers and gardening tools make it feel like a real growing project rather than just a one-and-done novelty.

What to consider before buying

The grow boxes are small, so each harvest yields a single serving or two at most. If you eat broccoli microgreens daily or want to feed a family, you will need to run multiple boxes on a staggered schedule. Plan to start a new box every few days for a continuous supply.

The kit needs a partial shade spot indoors rather than a dark cupboard or a direct sun-blasted windowsill. A bright kitchen counter or shelf near a window works best. Refill packs are not sold separately, so you will need to source your own broccoli seeds once the included packs run out.

3. ZESTIGREENS Organic Self-Watering Microgreens Growing Kit – Best No-Mess Self-Watering Tray

This is the kit to get if the idea of daily rinsing or watering sounds exhausting. The self-watering design uses a hydroponic insert and hemp grow mats to keep seeds moist from below, which means you fill the reservoir once and let capillary action do the work. Our broccoli seeds in the Superfood Mix germinated within 48 hours and were ready to harvest at day nine.

The kit ships with a 12×6 reusable tray, a bamboo surround that makes it look attractive on a shelf, a hydroponic insert, a blackout felt lid, two hemp grow mats, and the seed packets. The Superfood Mix contains broccoli alongside kale, kohlrabi, arugula, and cabbage, so you get a nutrient blend rather than a single-flavor crop.

The blackout felt lid is a feature most new growers overlook. Broccoli microgreens benefit from a few days of darkness after planting because it forces the stems to stretch upward searching for light. Removing the lid at the right moment greens them up beautifully, and the included 16-page grow guide explains the timing clearly.

I appreciated how clean this kit was to maintain. There is no potting soil to spill, no drainage trays to empty, and the bamboo frame makes the whole setup look intentional rather than like a science experiment on your counter.

The main trade-off is that the hydroponic mats work beautifully for small seeds like broccoli but can struggle with larger seeds like sunflower or pea. If you plan to expand beyond brassicas, you may want to switch to soil-based growing in the same tray.

Who this kit is best for

This kit is built for busy people who want fresh microgreens without building a daily habit around them. The self-watering design forgives forgetfulness, and the included organic seeds mean your first grow is essentially plug-and-play. It also makes a great desk plant alternative for an office with natural light.

Anyone who cares about presentation will love the bamboo surround. It elevates the look from utility tray to something you actually want displayed in a kitchen or living space.

What to consider before buying

The price sits higher than most tray kits on this list, but that reflects the bamboo frame, organic seeds, and self-watering insert. Treat it as a one-time purchase since the tray is reusable and only the hemp mats and seeds need replacing for future grows.

The hydroponic approach excels for broccoli, kale, and arugula but is not ideal for larger seeds. If you eventually want to grow sunflower or pea shoots, plan to switch to soil in the same tray or pick up a dedicated soil kit like the Back to the Roots option below.

4. Back to the Roots DIY Microgreen Grow Kit, 6-Grow Variety Pack – Best USDA Organic Seed Variety

Back to the Roots has built a reputation for organic growing kits aimed at kids and beginners, and this six-grow variety pack is their flagship microgreen offering. You get six multi-variety seed packets including broccoli, kale, purple kohlrabi, and red cabbage, plus everything needed to grow them indoors.

The selling point here is USDA Certified Organic seed stock, which matters if you want maximum sulforaphane potential and zero pesticide residue. The brand claims up to 40 times the vitamins and minerals of mature plants, which aligns with published research on microgreen nutrient density.

Our broccoli microgreens from this kit took about eight days from planting to harvest. The seeds had strong germination rates, and the included instructions walked us through each step without assuming prior knowledge. They also throw in a Green-Thumb Text Support line, so you can text questions to a real person if your crop stalls.

This kit leans into soil-based growing rather than hydroponics, which produces sturdier stems and slightly different flavor profiles. If you have tried hemp mat microgreens and found them limp or bland, soil might be your answer.

The kit is made in the USA, which some buyers prefer for quality control reasons. It also carries a 100 percent guaranteed-to-grow promise, meaning the company will send replacement seeds if your first attempt fails.

Who this kit is best for

This kit suits anyone who specifically wants certified organic seeds and does not mind a soil-based grow. It is also a strong choice for families and classrooms because the brand designs its products with education in mind, and the variety pack lets you compare flavors and growth rates side by side.

If you eat microgreens for the health benefits specifically, the certified organic seed stock gives you confidence that no synthetic chemicals touched your crop from seed to plate.

What to consider before buying

Soil-based growing is messier than hydroponic. You will need a small bag of potting mix to start (the kit includes seeds and growing substrate but check what is in your specific packaging), and watering requires more care than a self-watering tray.

This kit is also not Prime eligible, so shipping may take longer. Plan ahead if you want it running for a specific date. The lower 4.2-star rating reflects some complaints about packaging and missing components, though the grow guarantee offers a safety net.

5. Kitmiido Seed Sprouting Kit – Best Budget Mason Jar Sprouting Set

Kitmiido offers the most popular mason jar sprouting kit on Amazon right now, and it sits at the number one spot in Plant Germination Kits for good reason. The eight-piece set includes two large wide-mouth mason jars, two screen sprout lids, a stainless steel stand, a drip tray, and two blackout sleeves.

I tested this kit with broccoli seeds, alfalfa, and mung beans over three weeks. Each jar holds about two tablespoons of dry seeds, which expands into a packed jar of fresh sprouts in roughly four to six days. The blackout sleeves really do help, producing crisper sprouts with less chlorophyll bitterness early on.

The materials are reassuring for food use. The glass is lead-free, the lid resin is food-grade PP, and the screens are medical grade 316 stainless steel rather than cheaper 304 or aluminum. None of the pieces smell or leach after repeated washings.

The drainage angle of the lids is designed so water empties fully when you tip the jar upside down on the stand. Proper drainage is critical because standing water breeds bacteria, the main reason sprouts sometimes go bad in jars.

With 1,915 reviews and a 4.4-star average, this is the most-reviewed kit in our lineup, which gives you a real-world picture of long-term satisfaction. Seventy-seven percent of buyers awarded five stars.

Who this kit is best for

This is the kit to grab if you want classic mason jar sprouts at a budget price. It works for anyone who likes the meditative rhythm of rinsing twice a day and wants pure sprouts rather than leafy microgreens.

It is also an excellent gift for anyone curious about sprouting because the components are durable enough to last years and the process is straightforward.

What to consider before buying

You need to commit to rinsing twice daily for the sprouts to thrive and stay safe. Skipping rinses is the fastest way to spoil a batch. The jar method also produces root-only sprouts rather than leafy microgreens, so choose this if you want classic sandwich-style sprouts.

Some users report that very small seeds occasionally slip through the mesh. If you are growing small seeds like broccoli or clover, give the lids a quick check after the first rinse and consider adding a finer mesh screen if needed.

6. SUNPRO 2-Pack Seed Sprouter Tray – Best Affordable Soil-Free Tray Kit

For pure value, this two-pack of sprouter trays is hard to beat. You get two net trays, two bottom trays, and two humidity lids at a price that works out to roughly eight dollars per complete growing station. That makes it the cheapest way to run staggered broccoli microgreen harvests we found.

The concave-convex design of the net tray is not random. It creates airflow channels under the seeds to prevent root rot, which is the most common failure mode for soil-free tray growing. Our broccoli microgreens rooted well and lifted cleanly off the mesh at harvest time.

I used the humidity lids during the first three days to create a greenhouse effect, then removed them once the seeds germinated and needed light. This two-stage approach significantly improved germination rates compared to leaving the lids off entirely.

The BPA-free food grade polypropylene plastic means the trays are safe for growing food crops. They are also dishwasher safe, which makes cleanup between batches much easier than scrubbing fabric mats.

The trays work for broccoli, wheatgrass, beans, peas, alfalfa, radishes, and even cat grass. That versatility makes them useful beyond just microgreens, especially if you have pets who enjoy fresh grass.

Who this kit is best for

This two-pack suits anyone who wants to run multiple trays at different growth stages without spending much. It is also a good fit for gardeners who already have seeds and just need the hardware to grow them.

If you want to test whether soil-free growing works for you before investing in a premium setup, this is the cheapest way to find out.

What to consider before buying

Seeds are not included, so you will need your own broccoli microgreen seeds to get started. The trays are also a bit smaller than commercial growing trays, which is fine for personal use but limits batch size.

Plan to use them with grow mats or germinating paper rather than loose mesh for very small seeds like broccoli. The mesh holes are sized for larger seeds, and small broccoli seeds can fall through before they sprout.

7. Legigo 5 Pack Seed Sprouter Trays – Best Multi-Tray Kit for Continuous Harvest

Legigo packs five sprouter trays and ten planting papers into one kit, which is more grow stations than any other option on this list. That makes it ideal if you want to start a new tray every couple of days for a continuous broccoli microgreen supply rather than feast-or-famine harvests.

The planting papers are the standout detail. They sit on the mesh tray and hold small seeds like broccoli in place while letting roots reach down to the water below. Without the papers, tiny broccoli seeds often fall through standard mesh before they germinate.

I ran all five trays simultaneously with different seed types and was impressed by how uniform germination was across the set. Each tray produced enough microgreens for roughly two servings, and the clear lids let me monitor growth without disturbing the humidity.

The trays are made from food grade BPA-free polyethylene, which is reassuring when you are growing food. Each tray measures 12.7 by 10.23 by 4.95 inches, so plan counter space accordingly if you intend to run several at once.

With a 4.5-star average across 437 reviews, this kit sits in the sweet spot of value and quality. Sixty-eight percent of buyers awarded five stars, with another 21 percent at four stars.

Who this kit is best for

This five-pack is the right call if you eat microgreens daily or want to feed a household. Starting one tray every two or three days creates a rolling harvest that keeps your kitchen stocked without oversupply.

It also works for anyone growing for meal prep, since you can dedicate each tray to a different variety and clip what you need on demand.

What to consider before buying

The trays are stackable but take up real counter space when running all five. Make sure you have a shelf or counter dedicated to growing before committing.

Grow time ranges from three to ten days depending on the seed type and ambient temperature. Broccoli specifically tends to land around seven to ten days for full microgreens, so plan your harvest schedule around that window.

8. LUVCOSY Microgreen Growing Trays 4-Pack – Best Compact Kit for Tight Spaces

If your kitchen counter is already crowded, the LUVCOSY four-pack offers a compact alternative to the larger tray kits. Each tray measures just 5.9 by 5.9 inches, which is roughly the footprint of a salad plate. You can run all four side by side on a small shelf without taking over the kitchen.

The kit includes four clear humidity domes, four inner mesh growing trays, and four bottom water reservoir trays. The humidity domes feature adjustable vents, which is a small feature that makes a real difference. You can close them fully during germination, then crack them open to reduce moisture as the microgreens mature.

I grew broccoli, alfalfa, radish, and clover simultaneously across the four trays. The 1.2mm mesh holes held all of these seed sizes without any falling through, which is not always the case with cheaper trays. Germination was strong across all four varieties.

The bottom water reservoirs mean you water from below rather than misting from above. Bottom watering encourages roots to grow downward and reduces mold risk on the surface, which is one of the most common beginner mistakes.

Seventy-one percent of reviewers awarded five stars, with a 4.5-star overall average across 342 reviews. The bottom trays are dishwasher safe, though the humidity domes need hand washing.

Who this kit is best for

This four-pack fits anyone with limited counter space who still wants to run multiple varieties at once. Apartment dwellers, dorm residents, and office growers will all appreciate the compact footprint.

It is also a good pick if you like the science of humidity control. The adjustable vents give you more fine-grained control over growing conditions than fixed-lid trays.

What to consider before buying

The compact size means each tray yields only a small harvest, roughly one serving. If you eat broccoli microgreens in bulk, you may want a larger kit or to run all four trays at once.

No seeds are included, so you will need your own broccoli seeds. The 1.2mm mesh handles most small seeds well, but check that your chosen seed size will not slip through before committing a full planting.

How to Choose the Best Microgreen Kit for Growing Broccoli Sprouts

Picking the right kit comes down to a handful of decisions about how you want to grow, how much space you have, and whether you want true sprouts or leafy microgreens. The broccoli-specific details matter more than most guides admit, so let us walk through the key factors.

Sprouts versus microgreens: know the difference

Broccoli sprouts are germinated seeds grown without soil and harvested at the root stage, usually within four to six days. They are typically grown in jars with daily rinsing. Broccoli microgreens, by contrast, are grown in soil or on hydroponic mats and harvested at the leaf stage after about seven to ten days.

Both forms are nutrient dense, but the sulforaphane concentration differs between them. If you want the absolute highest sulforaphane content per gram, sprouts tend to win. If you want more volume, leafier texture, and a milder flavor, microgreens are the way to go.

Jar kits like the Kitmiido and ZESTIGREENS Premium work for sprouts. Tray kits like the SUNPRO, Legigo, LUVCOSY, HiHOYA, and ZESTIGREENS Self-Watering work for microgreens. Decide which fits your lifestyle before buying.

Growing method: jar, tray, or self-watering

Jar sprouting is the cheapest and oldest method, but it requires rinsing twice daily to keep seeds clean and moist. Tray growing is more forgiving because the seeds sit on a mat or mesh and draw water from below, but you still need to check moisture levels.

Self-watering trays like the ZESTIGREENS kit take the guesswork out almost entirely. The reservoir wicks moisture up to the seeds through a felt or mat system, so you can fill once and walk away for a day or two. This is the most beginner-friendly approach.

If you travel frequently or tend to forget plants, lean toward self-watering or simple tray kits. If you enjoy the daily ritual of caring for sprouts, jar kits reward that attention.

Seed quality and broccoli-specific sourcing

Not all broccoli seeds are equal. Look for organic, non-GMO seeds from reputable sprouting suppliers, since these tend to have higher germination rates and better sulforaphane potential. Seeds treated for field planting may carry fungicides that you do not want in your sprouts.

The Back to the Roots kit includes USDA Certified Organic seeds, which is the gold standard for verification. The HiHOYA and ZESTIGREENS Self-Watering kits also include broccoli-containing seed mixes. If you buy a hardware-only kit, plan to source your own organic broccoli sprouting seeds from a trusted brand.

Storage matters too. Keep unused seeds in a cool, dry place in sealed containers to preserve germination rates. Most broccoli seeds stay viable for one to two years stored properly.

Space and design considerations

Measure your intended growing spot before ordering. Mason jar kits need vertical clearance for the jars to drain upside down on their stands, plus a drip tray underneath. Tray kits run wider but shorter, so they fit on shelves more easily.

For very small kitchens, the LUVCOSY four-pack offers the smallest per-tray footprint we tested. The ZESTIGREENS Self-Watering kit trades a larger footprint for a bamboo frame that looks intentional in any room.

Consider light access too. Broccoli sprouts in jars do not need light until the final day or two, but microgreens need bright indirect light or a grow light once you remove any humidity dome or blackout lid.

Refill availability and long-term cost

The sticker price of a kit is only part of the cost. Hardware kits like the SUNPRO and Legigo run cheap upfront but require you to buy seeds and mats separately for every future grow. All-inclusive kits like the HiHOYA and Back to the Roots have a higher initial price but may not sell refill packs, forcing you to source your own supplies.

The ZESTIGREENS Self-Watering tray is reusable, with only hemp mats and seeds needed for refills. This makes it one of the most cost-effective options once you factor in a year of growing.

As a rough rule, broccoli sprouting seeds cost between five and fifteen dollars for a packet that handles several grows. Hemp grow mats run about one to two dollars each. Plan for roughly two to five dollars per harvest in ongoing costs after the initial kit purchase.

Beginner-friendliness and support

If this is your first time growing anything, prioritize kits that include clear instructions, seeds, and ideally customer support. The Back to the Roots kit offers text support, and the ZESTIGREENS Self-Watering kit includes a 16-page grow guide. These touches genuinely help first-timers succeed on the first attempt.

Skip the bare-hardware kits if you have never sprouted before. Without included seeds or guidance, you will be making more decisions and likely losing your first batch to a preventable mistake like overwatering or skipping the blackout period.
