The Kernel
Chemical Formulas
Process
Kernel= 0.15 grams
14% of kernel is water
0.15 • 0.14 (% of H2O in kernel) =.021 grams of H2O in a single kernel
.021g/ 18.016 (H2O molar mass) = .0012 moles of water in a single kernel

Our Opinion
It's AMAZING!!!
Shocked by the harmful chemicals

Planted 1.5 inches deep
Germinate in 7 days
Plants reaches 8 ft.
Harvesting
Mature when stalk is brown and dry
Moisture 16-20%
Drying bins
Processing
