Consider the following about Saffron Cultivation:

1. Saffron grows well at an altitude of 2000 meters above sea level and needs a photoperiod (sunlight) of 12 hours.

2. It grows in many different soil types but thrives best in calcareous (soil that has calcium carbonate in abundance), humus-rich and well-drained soil with a pH between 6 and 8.

Which of the above statements is/are correct?
