Cost Analysis Cost to make greenhouse: ~$925 Operation of greenhouse: 4.2 kWh per day At $0.12/kWh electricity cost and 60 days to grow tomatoes, costs $30.24 to grow 6 tomato plants, which each yield ~12-15lb of tomatoes = ~80 lb total Nutrients cost ~$15 per 60 days = ~$45 total for 80 lb of tomatoes … ~$0.56/lb Store-bought tomatoes average ~$2.00/lb shaun 12 12 12

Cost Analysis… Break even after 642 lb of tomatoes = 8 (60 day) seed to harvest growth cycles If spacing cycles 1 month apart, takes 2 years to break even Shaun, 8 lb to make a quart of spaghetti sauce, Savings over 10 years = $3800 13 13 13
