3. The Problem Widespread access to local produce Food deserts
Reduce carbon footprint of shipping
For people without the time, space and knowledge to garden

4. Our Solution: Fully Automated Smart Greenhouse
Array of sensors inside greenhouse
Continuous measurements
Displays information on app
Sensor data used for the water pump and nutrient dispersal control

12. 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

13. 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
