​Indoor Farming: A Hidden Environment Problem
VEGETABLE PRICES ARE VOLATILE
The prices of vegetables are fluctuating now more than ever
The price of Lettuce has gone up to 6 TIMES
THE SOLUTION?
INDOOR FARMING
was created to stop pricing issues
but instead lead to:
HIGH CARBON PRODUCTION
Created using high heat, high energy processes to create rock - into wool which causes lettuce to
have CO2 emissions that are up to 32 times its weight.
​
TOTAL COâ‚‚ EMISSIONS
The average Canadian car emits up to
4500 kg of CO2 per year
50% of UofT's lettuce growth emits the
same amount in a month
If all Canadian lettuce was grown indoors:
that number would increase by up to
300 times.
This is just for ONE vegetable.

Grodan Rockwool Grow Medium
​
USES HIGH HEAT​
= VERY ENERGY INTENSIVE
Min of 1000kg CO2 per shipment
Up to 20-32kg CO2/kg-lettuce
​EMISSIONS PER SHIPMENT
Even with optimized transport, a minimum of 1000 kg COâ‚‚ emissions per shipment is expected, and overall emissions can range between 20-32 kg COâ‚‚ per kilogram of lettuce depending on farming practices.
ROCKWOOL BASED FARMING
Competitor farms using rockwool generate approximately
32 kg COâ‚‚ per kilogram of lettuce.
