Why my seeds didn't germinate? I tried to soak it overnight and straight putting it to jiffy peats.
maybe because of, I was using tap water, or too deep digging the jiffy peats?
Peat can sometimes be acidic. And it sounds like way too much water. Try the 24hr soaking in water and then the paper towel method for 2-3 days. Submerged in soil, tap root down. Thousand of videos on YouTube! Good luck!
I don't know if you mistyped the 1.89L/24h, but if that's not the case you drowned them. You want the pellets to stay moist but not soaked. A little sprayer will help be a little more conservative. Overwatering is one of the most common mistake.
