Click and Grow Smart Garden 9 ($300) and AeroGarden Harvest 2.0 ($150) are the two top-selling 6-9 pod countertop hydroponic systems on the market. They look similar at a glance but diverge sharply on design philosophy, capsule ecosystem, app capability, and value. After running both side-by-side for 12 weeks with identical herb and lettuce loadouts, the verdict: AeroGarden wins on value, Click and Grow wins on aesthetics, and the choice mostly comes down to your kitchen.
Quick Verdict: Which One Should You Buy?
Buy AeroGarden Harvest 2.0 if: budget matters, you want the largest pod ecosystem, you want robust app features, you’ll experiment with growing from your own seeds. Buy Click and Grow Smart Garden 9 if: kitchen aesthetics matter (the device looks like Scandinavian industrial design), you want a sealed-pod ecosystem with no nutrient mixing, you prioritize quiet operation. Skip both if you want serious harvest volume — go to a Lettuce Grow Farmstand instead.

Design and Aesthetics
Click and Grow wins this category decisively. The Smart Garden 9 is designed in Tallinn, Estonia by an industrial design firm with Apple-store sensibility. Matte plastic, soft-glow LED, minimal labeling, the device looks like a kitchen appliance you’d display rather than hide.
The AeroGarden Harvest 2.0 looks utilitarian — closer to a small office printer than a kitchen appliance. The light arm has visible plastic seams and the LED module is exposed. It works, but it doesn’t earn placement on a marble counter.
If your kitchen has been featured in Dwell, buy the Click and Grow. If you’ll keep the unit in a basement, garage, or pragmatic corner, save the $150.
Pod Ecosystem
AeroGarden’s ecosystem is broader: 50+ pod varieties including Italian Herbs, Salad Greens, Heirloom Tomato, Sweet Pepper, Mountain Meadow Flowers, plus a Mushroom Mix that grows in pucks (not pods).
Click and Grow’s ecosystem is 40+ varieties with a sharper Mediterranean-skewing selection: Genovese Basil, Pre-Mix Greens, Tarragon, Watercress, Dwarf Cherry Tomato. They lean into specialty herbs that AeroGarden doesn’t carry.
Both companies sell capsule subscriptions ($9-12 per 3-pack, regular shipments). Both work with their own brand only — capsules are not interchangeable.
The “grow your own seeds” answer differs:
- AeroGarden: Sells a Grow Anything kit ($20 for 3 baskets) explicitly for owner seeds. Officially supported.
- Click and Grow: Owner-seed pods technically work but void the warranty. The plant capsules are sealed proprietary units; refilling them with your seed is not supported.
App Comparison
AeroGarden’s app is the better software product. Plant tracking by pod position, harvest reminders, water and nutrient notifications, vacation mode, voice integration with both Alexa and Google.
Click and Grow’s app is functional but lighter. Plant tracking, light scheduling, basic reminders. Voice integration is Alexa-only and limited. The app’s strength is plant care guides — they include extensive content on each variety.
Neither app does sensor-based automation (pH, EC, water level beyond basic depth). Both rely on manual user observation for these.

Operation: 12-Week Side-by-Side Test
I ran both units with identical herb-and-lettuce loadouts for 12 weeks. Tracked yield, time spent on maintenance, and plant health.
| Metric (12 weeks, identical pods) | AeroGarden Harvest 2.0 | Click and Grow Smart Garden 9 |
|---|---|---|
| Total harvest weight | 11.3 oz | 14.8 oz (more pods, smaller plants) |
| Time to first harvest | 22 days (basil) | 26 days (basil) |
| Plant health (subjective 1-10) | 8.5 | 8.0 |
| Maintenance time per week | 3-5 minutes | 2-4 minutes |
| Days reservoir lasted (peak growth) | 5-7 | 3-5 (smaller reservoir) |
| Algae issues | Minor (covered with foam ring) | None (sealed design) |
| Pump noise complaints (housemate test) | Yes, 1 of 2 housemates noticed | None |
Yield is comparable per device (Click and Grow gets more total weight from 9 vs 6 pods, but per-pod yield is lower because of smaller water reservoir).
The big practical difference: Click and Grow’s smaller reservoir means more frequent refills during peak growth. AeroGarden’s bigger 1-gallon reservoir lasts a week in mature herb stage.
Cost Over 3 Years
| Item | AeroGarden Harvest 2.0 | Click and Grow Smart Garden 9 |
|---|---|---|
| Initial unit | $150 | $300 |
| Year 1 pods (4 cycles, all pods) | $80-120 | $120-160 (more pods) |
| Year 1 nutrients | $25 | $0 (in capsules) |
| Year 1 electricity | $18 | $13 |
| Year 1 total | $273-313 | $433-473 |
| 3-year total (replacement) | $520-640 | $720-840 |
AeroGarden saves $200-260 over 3 years. If aesthetics aren’t worth that to you, AeroGarden wins on math.
The Honest Recommendation
For 80 percent of buyers: AeroGarden Harvest 2.0. Better value, broader pod ecosystem, mature app, larger reservoir means less refilling. The plastic-and-seams aesthetic is the only real drawback.
For 20 percent of buyers (design-forward kitchens, gift purchases, anti-AeroGarden brand sentiment): Click and Grow Smart Garden 9. Pretty unit, sealed-capsule simplicity, slightly quieter pump.
For neither: if you want serious harvest volume, both 6-9 pod countertop systems are inadequate. Step up to a tower system — see our Lettuce Grow Farmstand guide.
For broader hydroponic context, see Hydroponics for Beginners and Best Plants for Hydroponic Growing.
Common Mistakes Buying Either
Buying for tomato production. Neither unit grows full-size tomatoes well. Cherry tomatoes work for 4-6 weeks then outgrow the light. For tomatoes, get AeroGarden Bounty or Lettuce Grow Farmstand.
Buying for “self-sufficient” salad supply. 6-9 pods produce 8-15 oz of greens per month. That’s a side dish, not a meal supply. Manage expectations or buy a tower.
Putting in a bedroom. Pump noise on both units (28-32 dB AeroGarden, 22-25 dB Click and Grow) is mild but constant. Light scheduling means lights run during your wake hours, but the pump runs in cycles regardless.
Skipping pod brand alignment. AeroGarden pods don’t fit Click and Grow units and vice versa. If you switch brands, you start the pod ecosystem cost over.
Click and Grow vs AeroGarden: which is better?
For value and pod ecosystem breadth, AeroGarden Harvest 2.0 ($150) wins. For design aesthetics and quiet operation, Click and Grow Smart Garden 9 ($300) wins. AeroGarden saves $200-260 over 3 years; Click and Grow looks better on a counter.
Are Click and Grow capsules better than AeroGarden pods?
Click and Grow capsules contain pre-measured nutrients sealed in (no separate nutrient mixing). AeroGarden pods require manually adding nutrient packets every 2 weeks. Click and Grow is simpler; AeroGarden is more flexible. Both produce comparable plant health.
How does the Click and Grow app compare to AeroGarden?
AeroGarden’s app is more polished — better plant tracking, more reminders, full Alexa and Google integration. Click and Grow’s app is functional with stronger plant-care guides but limited voice integration (Alexa-only) and lighter reminder system.
Can you use AeroGarden pods in Click and Grow?
No. The pod sizes and reservoir interface are not compatible. AeroGarden pods are open baskets; Click and Grow capsules are sealed proprietary units. Switching brands means starting your pod ecosystem from zero.
Which is quieter, Click and Grow or AeroGarden?
Click and Grow Smart Garden 9 is quieter at 22-25 dB (barely audible) vs AeroGarden Harvest 2.0 at 28-32 dB (quiet desk fan). The difference matters in bedroom or office placement; in a kitchen, both are fine.
Is Click and Grow worth twice the price of AeroGarden?
Only if kitchen aesthetics matter to you. Pure functional comparison: AeroGarden has more pods variety, larger reservoir, mature app, and saves $200-260 over 3 years. Click and Grow’s premium goes to industrial design and quiet operation.
