Germination Instruction:
1. Soak seeds into water between 100F 105F, 38C-41C for 15 to 20 hours. Soaking seeds before planting helps to break down the seed's natural defenses which allows them to germinate faster.
2. Take seeds out. Place seeds in clean moisten paper towel. Fold paper towel and keep it in ziploc bag and place ziploc bag in dark and warm place (75F-85F ). Make sure paper towel is always moist and spray water as needed. After 7-15 days, seeds should germinate.
3. Use potting mix or seedling soil to plant seeds. Plant seeds at a depth equal to two or three times their width. Make sure to spray twice daily to keep the ground moist (but not too wet).
4. After 1 month, they grow between 2-3 inches tall. Keep spray water twice per day. Transplant them to bigger pots if planted in seed starter pots or plant them on ground after 2-3 months old. When temperature drops below 50F, plants should be covered frost blanket. If in pot, store inside warm place near the sun light.
