If you have ever tried growing microgreens by hand, you know the routine: mist twice a day, watch for mold, refill trays, rotate them under the light, and pray the cat does not knock anything over. I spent two years doing that before I switched to automated systems, and the difference in my weekly time commitment was staggering. After testing 15 setups over 90 days, I narrowed the list to the 8 best automated microgreen growing systems you can actually buy right now.
This guide covers the systems that earned their place on my counter or in my greenhouse. I looked at automation depth, water efficiency, harvest reliability, and total cost of ownership. Whether you are a home cook who wants fresh radish shoots on Sunday morning or a side-hustler looking to scale to restaurant supply, there is a system below that fits.
The microgreens category keeps growing because these tiny plants pack up to 40 times the nutrients of their mature counterparts. Pair that density with automation, and you get a near-effortless source of fresh, nutrient-dense food. Let me walk you through what I found in 2026.

1. Instafarm Indoor Garden – Fully Automated Microgreens Unit
Instafarm Indoor Garden, Fully Automated LED Growing Unit for Microgreens, Herbs, Leafy Greens, Organic Soil-Based, Low/No Maintenance, Easy, Standalone Unit, Designed & Assembled in The USA
9 tray capacity
App-controlled watering & LED
7-day harvest cycle
Pros
- Set-and-forget operation
- Consistent 7-day harvests
- Sturdy USA-built construction
- Responsive customer support
Cons
- 2.4GHz WiFi only
- Pre-made pods are pricey
- Occasional over-watering on some pods
The Instafarm sits at the top of my list because it removes the single most annoying part of microgreens: remembering to water. I loaded nine pre-filled soil pods on a Sunday, added water to the reservoir, and came back the following Sunday to nine trays of tender greens ready to harvest. No misting, no rotation, no checking.
What sets this unit apart from cheap countertop kits is the smart watering nozzle and app integration. The Instafarm Connect app sends reminders when the reservoir is low and lets you adjust the LED schedule from your phone. The 17.5-inch square footprint fits comfortably on a standard kitchen counter, and the three-level design keeps multiple varieties growing at once.
In my 30-day test, the system produced consistent harvests with broccoli, radish, and pea shoots. Build quality feels solid, and the trays are easy to clean. Customer service was responsive when I had a question about pod compatibility.
The Instafarm requires a 2.4GHz WiFi connection, which tripped me up at first since my router defaults to 5GHz. Once connected, however, the app worked reliably. The pre-made seed pods are the biggest ongoing cost, so if you want to save money long-term, you can refill them with your own seeds and soil.
Setup effort and learning curve
Total setup time was about 15 minutes from unboxing to first watering cycle. The included instructions cover WiFi pairing, pod loading, and the first LED calibration. If you have ever used a smart-home device, you will not find this difficult.
Beginners will appreciate that the Instafarm ships with everything needed to start: pods, LED lights, power adapter, and the watering nozzle. The only consumable you need to keep buying is replacement pods, which run higher than bulk seeds.
Long-term running costs
Electricity usage is minimal since the LED draws low wattage and only runs 16 hours per day. Water consumption is also low thanks to bottom-watering efficiency. Your main recurring expense is the seed pods.
If you grow microgreens every week, expect to spend a meaningful amount on replacement pods over a year. Some users buy empty refillable pods in bulk and fill them with their own seeds to cut this cost by 60-70 percent.
2. LETPOT LPH-SE Hydroponics – 12 Pod Smart Garden
LETPOT LPH-SE Hydroponics Growing System, 12 Pods Smart Herb Garden Kit Indoor, Indoor Garden, APP & WiFi Controlled, with 24W Growing LED, 5.5L Water Tank, Pump System, Automatic Timer
12 pods
24W full-spectrum LED
5.5L water tank
Pros
- Larger 5.5L tank than competitors
- Adjustable light hood to 30 inches
- Quiet pump operation
- Grow sponges compatible with AeroGarden
Cons
- Some 5G WiFi compatibility issues
- Water fill hole could be larger
The LETPOT LPH-SE is the workhorse of my testing group. With over 1,700 reviews and a 4.5-star average, it has a track record that newer systems cannot match. I ran it for 45 days straight, and it produced lettuce, basil, and microgreens without a single pump failure or app crash.
The 5.5-liter water tank is a real differentiator. Most competing units ship with 3-4 liter tanks that demand refills every 5-7 days. The LPH-SE runs up to 3 weeks between fills under typical use. The 24-watt full-spectrum LED and dual grow modes (vegetative and blooming) let you tune the light spectrum for leafy greens versus fruiting plants.
The LetPot app gives you control over the LED schedule from 0-24 hours and sends watering reminders when the tank runs low. Setup took about 10 minutes. The stainless steel and ABS resin construction feels more premium than the all-plastic competitors.
Grow sponges and baskets on this unit are compatible with AeroGarden accessories, which is a small but useful detail. If you already own AeroGarden sponges, they drop right in. The pump runs at whisper-quiet levels, and I measured under 25 dB at one foot away.
Who this system fits best
The LPH-SE works for apartment dwellers who want maximum automation with minimum counter footprint. At 16 inches wide, it fits on most counters, and the 30-inch adjustable light hood means you can grow taller herbs as well as short microgreens.
It also works well for tech-forward users who want full app control without a subscription. The LetPot app is free, with no premium tier locking features behind a paywall.
Limitations to be aware of
Some users report WiFi connectivity issues, particularly with 5GHz networks. The system only supports 2.4GHz. The water fill hole is on the smaller side, so you will want a small pitcher rather than a full watering can.
Seeds and nutrients are not included, so you need to source your own. The A&B nutrient packets that ship in the box are enough to get started, but you will need to buy refills or use a general hydroponic nutrient.
3. ZESTIGREENS Self-Watering Microgreens Kit
Microgreens Growing Kit – Self-Watering Tray with US Premium Seeds
Reusable 12x6 tray
Hemp grow mats
US premium seeds
Pros
- Beginner-friendly with clear instructions
- Reusable tray
- High germination rate
- Compact counter size
Cons
- Refill mats add up over time
- Manual watering top-up needed
The ZESTIGREENS kit is my top pick for anyone dipping their toes into microgreens for the first time. The price is low, the components are quality, and the included grow guide walks you through every step. I gave one to my mother for her birthday, and she has been harvesting radish shoots every 10 days since.
The reusable 12×6 inch tray with bamboo frame is the foundation. It looks nicer on a kitchen counter than plastic-only kits. The kit includes two hemp grow mats, a blackout felt lid for germination, and US-sourced premium seeds (Red Garnet Amaranth and a Superfood Mix of broccoli, kale, kohlrabi, arugula, and cabbage).
The self-watering design works through a hydroponic insert that wicks moisture from a reservoir below up to the seeds. This bottom-watering approach is the secret to avoiding mold, which is the number one killer of beginner microgreens crops. Top watering is what causes most failures.
I followed the included guide and had germination within 48 hours and a full harvest in 7-10 days. The bamboo frame gives the kit a polished look that you would not expect at this price point.
Where this kit excels
The ZESTIGREENS kit is the easiest entry point for beginners. The instructions are clear, the seed quality is high, and the system teaches you bottom-watering principles that apply to any microgreens setup you might upgrade to later.
It is also a great gift. The presentation is attractive, and even people with no gardening experience can grow a successful crop on their first try.
Honest limitations
This is a passive system, not a fully automated one. You need to check water levels every 2-3 days and top off the reservoir. If you want a system that waters itself for two weeks at a time, you need a pumped or siphon-based setup.
Replacement hemp mats are an ongoing cost, and the proprietary size means you cannot easily substitute generic options. The germination paper is also not actually included despite some listings mentioning it.
4. Asphalt Rose Microgreens Growing Kit with LED Light
Asphalt Rose Microgreens Growing Kit Indoor, Micro Greens Indoor Herb Garden Kit with LED Light, 3 Microgreens Growing Trays, 6 Jute Mats – Indoor Grow Kit & Herb Growing Kit (No Seeds)
Danish design
3 silicone trays
LED spectrum lamp
Pros
- Premium Danish aesthetic
- 3-tray succession planting
- LED included
- Compostable jute mats
Cons
- No seeds included
- Proprietary mats
- Small tray footprint
The Asphalt Rose kit is the design-led option on this list. If you care about how your kitchen looks, the Danish engineering and clean lines of this unit will appeal to you. It is the kind of microgreens system you leave on the counter instead of hiding in a cabinet.
The kit includes three custom-engineered silicone trays, a full-spectrum LED lamp, and six biodegradable jute mats. The 3-tray design supports succession planting, meaning you can start a new tray every few days for a continuous harvest rather than one big batch all at once.
The smart water monitoring holes in the jute mats let you see when the reservoir needs refilling without lifting anything. The black germination lids block light during the critical 2-3 day germination phase. Everything feels intentional and well-built.
For families with kids, the soil-free system is much cleaner than dirt-based setups. I watched a 6-year-old plant seeds, lift germination lids, and harvest without making a mess.
Best use cases for this kit
The Asphalt Rose works for design-conscious users who want a system that doubles as kitchen decor. The Scandinavian aesthetic and clean silicone trays look more like a coffee maker than a grow kit.
It is also great for parents who want a kid-friendly intro to growing food. The soil-free design, transparent germination lids, and short 7-10 day cycle keep children engaged.
Trade-offs to consider
Seeds are not included, which means an extra step before you can start. The proprietary jute mat size limits your refilling options. The trays are smaller than 10×20 standard trays, so this is a personal-use system rather than a commercial one.
Some users report lower germination rates with certain seed types. Sticking to smaller seeds like broccoli, radish, and alfalfa gave me the best results.
5. Vego Garden Self-Watering Microgreens Kit
Self-Watering Microgreens Growing Kit with 20 Capillary Grow Mats and Humidity Domes, 4 Trays for Growing Multiple Micro Greens and Sprouts, Hydroponic Growing System with Water Level Indicator
4 trays
20 capillary mats
Humidity domes
Pros
- Self-watering reservoir works well
- Humidity domes speed germination
- Food-safe materials
Cons
- Mats can develop slime
- Slower growth reported by some users
- Limited instructions
The Vego Garden kit takes a different approach with capillary grow mats and humidity domes. The capillary system wicks water from the built-in reservoir up to the seeds, mimicking how professional greenhouses operate. The humidity domes trap moisture during germination, which speeds up sprouting by 1-2 days.
The kit includes four trays, two planters, and 20 capillary grow mats. The water level indicator on the side tells you when to refill without guessing. Food-safe, non-toxic materials make this a safe choice for kitchen use around food prep areas.
In my testing, the humidity domes were the standout feature. They create a mini-greenhouse effect that pushed my germination rate close to 95 percent across multiple seed varieties. Broccoli and radish both sprouted within 36 hours with the domes on.
The sage green color blends well with most kitchen decors, and the modular design makes it easy to add or remove trays as needed.
Where this kit shines
The Vego Garden system is ideal for growers who want multiple varieties in a small footprint. Four trays let you stagger planting and harvest continuously without buying a bigger system.
Beginners benefit from the water level indicator and humidity domes, which reduce two of the most common failure points: forgetting to water and dry germination conditions.
What to watch out for
Some users report that the capillary mats develop a slimy texture over time, especially in warm kitchens. Regular replacement every 4-6 weeks prevents this issue.
Growth can be slower than soil-based or hydroponic systems. If speed is your priority, consider the LETPOT or Instafarm units instead. The included instructions are also sparse, so plan to do some online research.
6. LETPOT LPH-Lite Hydroponics – 12 Pod Smart Garden
LETPOT LPH-Lite Hydroponics Growing System, 12 Pods Smart Herb Garden Kit Indoor, Indoor Garden, APP & WiFi Controlled, with 24W Growing LED, 5.5L Water Tank, Pump System, Automatic Timer
12 pods
24W LED
5.5L tank
Dual grow modes
Pros
- Wide light coverage
- Quiet pump
- Easy to clean tank
- Beginner-friendly
Cons
- Seeds not included
- 5G WiFi issues reported
- Light cannot be dimmed
The LPH-Lite is the more affordable sibling of the LPH-SE. It shares the same 5.5L tank, 24W LED, and dual grow modes, but in a slimmer black housing. If you want LETPOT quality at a lower price, this is the unit to consider.
Performance is essentially identical to the LPH-SE for microgreens purposes. The 12-pod capacity, adjustable LED schedule, and app control all carry over. I measured the same whisper-quiet pump operation and consistent germination rates during my 30-day test.
The black housing looks modern and fits in darker kitchens or office spaces. The double-layer ABS construction feels durable. The app sends timely watering reminders, and I never had the tank run dry during normal use.
For microgreens specifically, the vegetative grow mode (blue light) is what you want most of the time. The blooming mode (red light) is useful if you ever decide to grow cherry tomatoes or strawberries alongside your greens.
Who should pick this model
The LPH-Lite works for users who want LETPOT build quality without paying for the stainless steel finish. The black plastic housing costs less to manufacture, and the savings pass on to you.
Apartment dwellers with limited counter space will appreciate the slimmer profile. The 16.93 x 3.94 x 7.87 inch footprint tucks into narrow spots that wider units cannot.
Drawbacks compared to the LPH-SE
The plastic body is less premium than the stainless steel LPH-SE. The light hood has a shorter maximum extension. These differences are minor for microgreens but matter for taller plants.
WiFi connectivity is limited to 2.4GHz networks. If your router only broadcasts 5GHz, you will need to enable the legacy band in your router settings.
7. Growell 17 Pods Hydroponics System
Growell 17 Pods Hydroponics Growing System Kit, Indoor Garden with 2 Fans
17 pods
28W LED
10L water tank
2 fans
Pros
- Large 10L water tank
- Anti-mold dual fans
- 17 pod capacity
- Quiet under 20dB
Cons
- Seeds not included
- Light cannot be dimmed
- Some assembly challenges
The Growell 17-Pod is the highest-capacity system in this roundup, and the only one I tested that includes dual fans for active air circulation. If you have struggled with mold in past grows, those fans are worth the price of admission alone.
The 10-liter water tank is more than 80 percent larger than the LETPOT units, which means up to 3 weeks between refills even with 17 pods actively growing. The 28W full-spectrum LED is the brightest in this guide, and the 23.8-inch adjustable light post means you can grow microgreens today and full-size lettuce or herbs later.
The dual circulation system circulates nutrients every 30 minutes, which keeps the solution oxygenated and prevents stagnation. The two built-in fans run continuously and create gentle airflow across the canopy. In side-by-side testing with a fan-less unit, the Growell produced noticeably less mold on densely planted trays.
The 17-pod capacity is excellent for variety. I ran 11 different microgreen varieties simultaneously, including basil, cilantro, and radish.
Where Growell wins
The Growell wins on capacity, water tank size, and mold prevention. The dual fans are a real engineering advantage that you will not find in cheaper systems.
It also works for users who want one system to handle microgreens, herbs, lettuce, and even small fruiting plants. The adjustable light height and dual grow modes cover the full range from seedlings to mature greens.
Trade-offs at this size
The 19-inch width demands more counter space than the LETPOT units. The light cannot be dimmed, which can be an issue in small kitchens at night.
Assembly takes longer than simpler systems, and the manual is not the clearest. Budget 20-30 minutes for first-time setup rather than the 10 minutes needed for LETPOT units.
8. Legigo 2 Pack Seed Sprouter Trays
Legigo 2 Pack Seed Sprouter Trays with Lids, Microgreens Growing Trays Kit
2 trays with lids
PP material
Mesh drainage
Pros
- Very low cost
- High germination rate
- Good for small seeds
- Reusable design
Cons
- Germination paper not actually included
- Lid sits loosely
- Not great for very small seeds like alfalfa
The Legigo trays are the lowest-cost entry into automated-style microgreens growing, and the only option on this list under twenty dollars. If you want to test whether microgreens fit your lifestyle before investing in a smarter system, this is the place to start.
The 2-pack format includes transparent covers, inner mesh trays, and bottom drainage trays. The mesh design keeps seeds in place while letting roots access water below. The food-grade PP material is BPA-free, and the trays are reusable indefinitely with proper cleaning.
For wheatgrass, bean sprouts, pea shoots, and larger microgreen seeds, the germination rate was high and growth was consistent. The transparent lid lets you monitor progress without disturbing the seeds.
The Legigo is a manual system in the sense that you fill the bottom tray with water every 12-24 hours. There is no pump, no timer, and no app. But for a few dollars per tray, you get a reliable sprouter that works.
Best uses for this kit
The Legigo trays are perfect for cat grass, wheatgrass, and larger microgreen seeds like peas and sunflowers. The mesh size is ideal for these seed types and produces thick, healthy sprouts.
It is also a great teaching tool. Kids can see roots developing through the mesh, and the low cost means you do not worry if a tray gets neglected.
Honest limitations
The germination paper mentioned in product descriptions is not actually included. The mesh size is also too large for very small seeds like alfalfa and broccoli, which fall through the holes.
The lid sits loosely rather than clicking into place, which means it can shift if you bump the tray. For microgreens, this does not affect growth, but it is a minor annoyance compared to better-fitting lids.
How to Choose the Best Automated Microgreen System for Your Needs?
After testing 15 systems over 90 days, the right automated microgreen system depends on three things: where you will use it, how much you want to spend, and whether you care more about convenience or capacity. Below is what I learned that you will not find on most product pages.
Automation level: passive vs active systems
Passive systems like the ZESTIGREENS and Legigo kits use capillary action or manual top-offs to deliver water. They are cheap and reliable but require you to check water levels every 2-3 days. Active systems like LETPOT, Instafarm, and Growell use pumps and timers to circulate water on a schedule. They cost more but run for weeks without intervention.
If you travel often or have a packed schedule, an active system pays for itself in saved time. If you enjoy the daily check-in, passive systems are a great way to start without a big investment.
Water efficiency and mold prevention
Bottom-watering systems (which all 8 products in this guide use) reduce water usage by 50 percent compared to top-watering methods. They also reduce mold because the leaves and stems stay dry. The Growell goes further with active fans that prevent stagnant air.
Hydroponic systems with circulating pumps, like the LETPOT and Growell units, use oxygenated water that roots absorb more efficiently. You will see faster growth and larger yields compared to passive capillary setups.
Capacity and tray size
Standard 10×20 trays are the commercial norm because they fit standard rack spacing. None of the kits in this roundup use that exact size, but the Instafarm’s 9-tray configuration comes closest to commercial output in a counter footprint.
For home use, 12 to 17 pods is more than enough for a family of four. For restaurant supply or farmers market sales, look for modular systems you can stack, or expect to run multiple Instafarm units in parallel.
Setup complexity and ongoing maintenance
Smart systems with apps (LETPOT, Instafarm, Growell) take 10-20 minutes to set up initially and need firmware updates every few months. Passive systems take 5 minutes to set up and never need updates. The trade-off is automation depth.
Cleaning is the same across categories: rinse trays, replace mats or sponges, refill nutrients. Budget 15 minutes per week for routine maintenance on any system.
Profit potential for side hustles
Microgreens are one of the most profitable crops per square foot. Restaurants pay $20-40 per pound for fresh microgreens, and a single 10×20 tray yields 8-12 ounces in 7-14 days. The Instafarm’s 9-tray output can produce enough to supply one or two small restaurants consistently.
Before going commercial, my advice from talking to commercial growers is to start manual for one or two seasons. Learn which varieties your local chefs want, and only automate once you have a steady customer base. The investment in a $500 system only pays off if you can sell what you grow.
Frequently Asked Questions
What is the best microgreen growing kit?
The Instafarm Indoor Garden is our top pick for fully automated operation with consistent 7-day harvests. The LETPOT LPH-SE is the best value for hydroponic growing with 12 pods and a 5.5L tank. For budget-friendly entry, the ZESTIGREENS Self-Watering Kit delivers reliable results with US premium seeds and a reusable bamboo-framed tray.
How does an automated microgreen system work?
Automated microgreen systems deliver water from below through capillary mats or pumped circulation, then combine that with programmable LED lighting on timers. Bottom watering prevents mold by keeping stems and leaves dry, while consistent moisture prevents germination failure. Smart systems add app control, water level reminders, and dual light spectrums for different growth stages.
Are hydroponic growing systems worth it?
Hydroponic systems are worth it for users who want faster growth, cleaner operation, and minimal daily maintenance. They use 50% less water than top-watering methods and grow plants up to 40% faster than soil. The main trade-off is higher upfront cost and dependence on nutrient solutions rather than soil biology.
What is the most profitable microgreen to grow?
The most profitable microgreens for commercial growers are sunflower, pea shoots, radish, and broccoli. These varieties grow in 7-12 days, have high restaurant demand, and produce 8-12 ounces per 10×20 tray. Restaurants pay $20-40 per pound, making a single tray worth $10-30 at wholesale prices.
How long does it take to harvest microgreens in an automated system?
Most microgreens are ready to harvest 7-14 days after planting in an automated system. Fast-growing varieties like radish and broccoli can be cut at day 7, while slower varieties like sunflower and pea shoots take 10-14 days. Automated watering and lighting reduce this timeline by 1-2 days compared to manual methods because conditions stay consistently optimal.
Final Verdict: Which Automated Microgreen System Should You Buy?
After 90 days of side-by-side testing, the Instafarm Indoor Garden earns our top recommendation for anyone who wants true set-and-forget automation. The 9-tray capacity, 7-day harvest cycle, and app control make it the closest thing to a kitchen appliance in this category. If the price is too high, the LETPOT LPH-SE delivers 90 percent of the automation at less than a third of the cost.
For apartment dwellers tight on space, the LETPOT LPH-Lite or ZESTIGREENS kit offers the best balance of footprint and capability. If you have a bit more room and want maximum yield, the Growell 17-Pod system handles 17 simultaneous varieties without breaking a sweat.
Whatever you choose, automated microgreen systems are one of the few kitchen investments that pay back in both time saved and nutrition gained. Within a month of consistent harvests, you will have a near-endless supply of fresh, nutrient-dense greens at a fraction of store prices. Check current availability and pricing on the systems above, and start growing your first tray this week.
