Ongoing costs
Electricity is the main ongoing cost. A 150W LED run 18 hours per day uses 2.7 kWh per day. At 16 cents per kWh, that is $0.43 per day or about $13 per month. A 480W LED run 12 hours per day uses 5.76 kWh per day. At 16 cents per kWh, that is $0.92 per day or about $28 per month.
Add $20 to $60 per month for a full setup with fan, filter, and extra loads. Replace carbon filters every 6 to 12 months. Replace lights when output drops. Nutrients and medium add $30 to $80 per cycle.
Ways to cut cost
- Buy a kit. Kits bundle tent, light, fan, and filter. Kits cost less than buying parts alone.
- Use a 2x2 tent. Small tents need less light and less power.
- Choose a dimmable LED. Run it at 70% to 80% in veg.
- Skip a carbon filter if odor is not an issue. But odor control may be required by lease or law.
- Reuse pots, trays, and timers.
- Mix your own soil. This cuts medium cost.
Legal and safety notes
Cannabis laws vary by state and city. Check home grow limits, plant counts, and possession rules before you buy. Some states allow medical grows only. Some states ban home grow. Renters need landlord approval. Home insurance may not cover fire or water damage from a grow.
Use a GFCI outlet. Keep water away from power strips. Do not overload circuits. A 480W light draws about 4 amps at 120V. A 150W light draws about 1.25 amps at 120V. Add fan and other gear. A 15A circuit can handle most 2x2 and 3x3 setups. A 4x4 setup with extra gear may need a 20A circuit.
Ventilation matters. A sealed tent without airflow causes heat and humidity problems. Mold and powdery mildew can ruin a crop. Run an exhaust fan and keep humidity between 40% and 60% in flower. Keep temperature between 65F and 80F.
