How much does a countertop garden cost to run?
Electricity, pods, and refill costs for AeroGarden- and Click & Grow-class kits in an apartment.
What we’d put on the counter
AeroGarden Harvest (6-pod class)
Higher capacity; watch pump + pod spend
Check price at AmazonClick & Grow Smart Garden 3
Fewer pods; often quieter ongoing load
Check price at Click & Grow
The sticker price of a countertop garden is the down payment. Running cost is electricity + consumables. Most apartment growers overestimate power and underestimate pods.
Three cost buckets
- Power — the LED (and a small pump on some kits)
- Consumables — pods, nutrients, replacement sponges
- Replacements — failed first crops, extra light for jars, water changes
Electricity math (simple)
Use: watts × hours per day × days × your kWh rate.
Example: a 20W light × 15 hours × 30 days = 9 kWh. At $0.16/kWh that is about $1.45/month. Many Harvest-class and Smart Garden lights land in a similar low single-digit monthly range in typical US rates. Check your utility rate; the formula matters more than any one number.
Pumps add a little, not a second electricity bill.
Pod economics
Branded pods buy convenience. Cost per harvest depends on how often you actually cook with that herb.
| Path | Monthly feel | Notes |
|---|---|---|
| Branded pods every cycle | Higher | Easiest first month |
| Mix branded + blank inserts | Medium | Once germination is familiar |
| Soil pots / Kratky after month one | Lower | More watering attention |

Hidden costs
- Replacing leggy basil grown in weak light
- Buying a second clip light for jars on a dark counter
- Overfilling reservoirs before travel (spills cost more than nutrients)
Cheapest steady state
Grow only the herbs you snip weekly. Move refillable or soil setups for those, and keep one kit pod slot for the fussy plant you still want on a timer.
Budget starters: cheapest indoor herb garden under $50.
Key takeaway Power is usually a few dollars a month. Pods decide whether the garden feels cheap or expensive after week four.
