Warmth brother, initial germination requires 3 things, the seed needs darkness (replicates being buried under soil) warmth I personally let ambient temperature reach 84, I don't care what any guide says the wee babies love warm wombs and react much better imo. Use pure organic coconut water (not milk) this is natures very own embryotic fluid packed full of growth enzymes. Generally use the water for 24 hours nice and warm, above heater this will ease open the hard outer shell once opened I give another 24 hours in a paper towel kept toasty and humidity at 80 rh under a humidity dome, humidity is key ,if shell drys before seed has fully opened it ican have real problems prying it open.
