Why These Two Systems Dominate Indoor Tomato Cultivation
Indoor hydroponic gardening has exploded. Click and Grow and AeroGarden are the two titans. Both promise fresh tomatoes year-round. But their design philosophies diverge sharply.
AeroGarden, founded in Boulder, Colorado, uses a proprietary deep-water culture system with high-intensity LED lights. Click and Grow, headquartered in Estonia, relies on a wicking system with smart soil and lower-wattage LEDs. Your choice determines yield, taste, and labor.
For tomato growers especially, the difference is stark. AeroGarden Bounty or Farm models can produce up to 40 tomatoes per plant. Click and Grow caps around 15–20 due to smaller reservoirs and weaker lights.
Tomato Plant Size and Growth Height: Critical Differences
Tomatoes are vigorous vines. AeroGarden Farm 24XL towers at 36 inches. It accommodates indeterminate cherry tomatoes like ‘Red Heirloom’ that easily reach 24 inches. Click and Grow’s max pod height is 18 inches.
This forced height limitation means Click and Grow must use determinate or dwarf tomato varieties. Their official Tomato Mix uses miniature ‘Micro Tom’ genetics. While productive, you simply cannot grow full-sized beefsteak or Roma tomatoes.
AeroGarden’s adjustable grow light mast rises up to 12 inches above the tallest plant. This allows classic cherry tomatoes like ‘Sungold’ or ‘Sweet 100’ to thrive. Many users in AeroGarden forums report 5-foot vines trained horizontally under the lights.
Light Output and Spectrum: The Engine of Tomato Fruiting
Tomatoes demand high light intensity (PPFD) for fruit set. AeroGarden uses 50W full-spectrum LEDs with a color temperature of 3000K–5000K. Third-party spectrometer tests show PPFD at 12 inches of 400 µmol/m²/s—comparable to a high-end grow light.
Click and Grow uses 10W–20W LEDs depending on model. Their latest Smart Garden 9 Pro has a PPFD of about 180 µmol/m²/s at canopy level. This is 55% less light than AeroGarden. Less light directly reduces tomato yield and delays ripening.
Dr. Emily Carter, a horticultural researcher at Cornell University, states: ‘Cherry tomatoes need at least 300 µmol/m²/s for 14–16 hours daily to produce abundant fruit. Below 200, plants may flower but fruit set is poor.’ AeroGarden meets that requirement. Click and Grow does not.
Nutrient Delivery and Water Management
AeroGarden uses a submersible pump to circulate nutrient-rich water continuously. The reservoir holds up to 1.5 gallons on the Bounty. Click and Grow uses passive capillary wicking from a 0.7-gallon tank.
Tomatoes are heavy feeders. They deplete nutrients fast. AeroGarden’s active aeration and circulation prevent root rot and deliver oxygen to roots. Click and Grow’s static water can become stagnant. Users report needing to flush the system monthly to prevent algae.
Click and Grow’s smart soil pods contain slow-release fertilizer. This is convenient but not adjustable. If your tomatoes show nitrogen deficiency, you cannot correct it mid-cycle. AeroGarden’s liquid nutrient refills allow precise control, you can boost phosphorus during flowering or potassium during fruit swell.
Yield Comparison: Tomatoes Per Plant Per Cycle
Independent testing by indoor gardening blogger Lisa Chen at Urban Leaf Lab compared both systems side by side. Using identical ‘Tiny Tim’ cherry tomato seeds, she measured total yield over 90 days.
AeroGarden Bounty produced 1.8 kg (about 4 lbs) of tomatoes per plant. Click and Grow Smart Garden 9 yielded 0.6 kg (1.3 lbs) per plant. That’s a 3x difference. The average fruit size was 3.5g on AeroGarden vs 2.8g on Click and Grow.
Cycle time also differs. AeroGarden first harvest at 70 days; Click and Grow at 85 days. Faster growth means more harvests per year. With continuous planting, AeroGarden can deliver up to 5 cycles annually. Click and Grow yields 3 cycles at best.
Ease of Use and Maintenance: A Trade-Off
Click and Grow wins on simplicity. Insert a pod, fill the tank, plug in. Done. No pumps, no pH testing, no nutrient mixing. It is the ultimate ‘set it and forget it’ system.
AeroGarden requires initial setup of the pump timer, pH balancing, and nutrient dosing. Every 4 weeks you must empty and clean the reservoir. If you skip cleaning, algae and biofilm form. Tomato roots can clog the pump intake.
However, for tomato lovers, that extra maintenance is rewarded. AeroGarden’s water pump provides superior oxygenation. Roots stay white and healthy. Click and Grow’s roots often turn brown from oxygen starvation in warmer rooms—especially during summer when water temperature rises.
Cost Analysis: Initial Investment vs. Long-Term Value
| Model | Initial Cost | Pod Kit (3-pod) | Year 1 Total (with 3 cycles) | Tomato Cost per Pound |
|---|---|---|---|---|
| Click and Grow Smart Garden 9 | $99.95 | $19.95 | $159.80 | $26.63 |
| AeroGarden Bounty Basic | $199.95 | $15.95 | $247.80 | $10.33 |
| AeroGarden Farm 24XL | $399.95 | $15.95 | $447.80 | $7.46 |
Smart Features and App Integration
AeroGarden’s app is more mature. It sends push alerts when water or nutrients are low. The Bounty and Farm models have a color touchscreen with daily growing tips. You can track light hours, pump cycles, and harvest reminders.
Click and Grow launched their app later. It shows a weekly growth chart and lets you adjust light schedule via WiFi. However, connectivity issues are common. Many users on Amazon reviews report dropping connection after firmware updates.
For serious tomato growers, the AeroGarden’s data granularity matters. You can see exactly when your tomatoes enter the flowering stage based on light exposure. This allows you to optimize bloom nutrients. Click and Grow’s app treats all plants uniformly.
Pod Availability and Variety
AeroGarden offers over 50 seed pod varieties including ‘Red Heirloom Cherry’, ‘Golden Harvest Cherry’, ‘Thai Basil’, and ‘Dill’. Their tomato pods are specifically bred for hydroponic performance. Click and Grow offers about 20 varieties, with only one tomato mix.
Critically, AeroGarden sells ‘grow anything’ seed pod kits, empty pods with a grow sponge and dome. You can plant your own seeds. This is a game-changer for tomato enthusiasts who want ‘Brandywine’ or ‘Black Krim’. Click and Grow does not sell empty pods; you are locked into their capsules.

Noise and Heat Output
AeroGarden’s pump creates a gentle hum, about 30dB, similar to a whisper. The LED driver produces some heat; on the Farm model, the grow light can raise the room temperature by 2°F. In small apartments, this matters.
Click and Grow is completely silent. No pump. No fan. No heat from the low-wattage LEDs. For a bedroom or home office, Click and Grow is virtually invisible in terms of auditory impact.
But the heat from AeroGarden’s LEDs actually benefits tomato ripening. Tomatoes require daytime temperatures of 70–80°F. In a cool basement (60°F), Click and Grow’s pods may experience delayed growth. AeroGarden’s waste heat helps maintain optimal temperature.
Verdict: Which Should You Buy for Tomatoes?
If you want abundant, professional-grade tomatoes year-round, choose AeroGarden. The Farm 24XL gives you room to grow vining varieties, powerful LEDs, and precise nutrient control. The Bounty Basic is excellent for countertops with limited space but still outperforms Click and Grow.
If you prioritize absolute simplicity, silence, and don’t mind lower yields, Click and Grow is fine for occasional tomato snacking. It is perfect for herbs (see our herb guide). But for tomatoes specifically, the limitations are real.
Remember that even AeroGarden cannot mature a beefsteak tomato indoors under these small lights. For that, you need a proper tent setup (visit Gardener’s Supply Company). But for cherry tomatoes, AeroGarden is the clear winner.
Frequently Asked Questions
Can Click and Grow grow full-sized tomatoes?
No. Click and Grow systems have a maximum pod-to-light height of about 18 inches. This is insufficient for indeterminate or large-fruited tomatoes. They can only support dwarf or micro tomato varieties like ‘Micro Tom’ which produce small cherry-sized fruit.
How many tomatoes can I get from one AeroGarden plant?
A well-maintained AeroGarden Bounty or Farm can yield 30 to 50 cherry tomatoes per plant per cycle of 90–120 days. Some growers report over 100 from vigorous plants like ‘Sungold’ with proper pruning and support.
Is AeroGarden noisy for tomato growing?
AeroGarden pumps produce a low hum of about 30 decibels, comparable to a refrigerator. Most users do not find it bothersome in living areas. The noise is constant but unobtrusive. Click and Grow is silent.
Which system costs less per pound of tomatoes?
AeroGarden provides a lower cost per pound when amortized over multiple cycles. For the Bounty Basic, each pound of tomatoes costs roughly $10.33 in pods and nutrients. Click and Grow costs about $26.63 per pound due to lower yields and higher pod costs.
