Received the seeds. How do I start them? Pre-soak? Scarify? Potting medium?

You can start them in most any potting soil, but you should take a razor and knick the surface of each seed. Soak these in water for 24 hours prior to planting. Keep them warm with a heating pad if you can. This process will be very slow, and can sometimes take 3 or 4 months to germinate. Just have patience, and keep the soil barely moist in bright, indirect light until they come up.
