Warm moist stratification
Temperature: 70°F 21°C
70%, over 3-9 days.
Cold moist stratification
Duration: 90 daysTemperature: 40°F 4°C
Deno gives no length for this period; three months is his standard cycle.

Steps after step 1 run on after germination.
No stated waiting before sowing. Then 9 days to germinate.
70% germination in 3–9 days.
70% in the first nine days at 70. Two further cycles add 10% and 3% -- worth running for the remainder, but this is a warm germinator.
