Happy frog can be hot, you can mix it out with peat or coco, and rice hulls or pearlite 1/6 ea to help cool and fluff up the dirt. I like soak over night, paper towels till tiny tail plant 1/2 deep and mist with sprayer till they come up, then start water gingerly and keep misting every outher day till they are established. Pop them into 1 gal pots.
There are many ways to start seeds. My method yields 99% germination and healthy grow. I start indoors under T5 lights (16 hrs on, 8 hrs off) hung about 8” above pots using Happy Frog soil in 4” pots. Wet potting soil thoroughly then plant seeds 1/2” deep. Mist soil until seeds sprout in 3-5 days then wait a few days till next watering. I included pics of my 2021 seeds planted 4/1/21. 1st pic on 4/3 when most popped; 2nd pic 4/16 3rd pic 4/21, 4th pic 5/11 in ground.
