We have tried with soil and have been unsuccessful with very low germination.. We soak the seeds for 12 hours and then we seed. We tried both covered the seeds with dirt and extremely low germination. Then we tried without covering. We end up with mold and spray with hydrogen peroxide and still low germination. Temperature in room is between 68-70 and humidity zeroed 40-50. The seeds were purchased a month ago. Any tips 🙏
