How to use the calculator
End date is when you want to sell or plant the veggie.
2″ size column is when to start that plant and either sell or plant as a 2″ pot
4″ size column is when to start that plant and either sell or plant as a 4″ pot
Days-in-2″ pot includes time in germination container + time in 2″ pot.
Days-in-4″ pot includes Days-in-2″ pot + time in 4″ pot. I assume 7 days in new 4″ pot before planting.
End date should include time for hardening off plants.
