Germinated seeds not sprouted yet

if you do the paper towel method, i'd water those small recipticals long before you sow the germ'd seeds... lit them drip dry for at least 30 minutes, or preferably even longer... could be they were burried too deeply.. or twisted up on itself? (rhetorical possibility.. don't go digging.. do not go digging!) LOL. honestly.. skip the step, get over the ocd of "seeing" it happen, and just press down with a finger, pop a seed in and loosely cover and tamp down 1/2" deep... should be enough to pull the shell off.. if too shallow, you have to take the shell off more often... if too deep it takes several extra days to break ground. it'll germ in the same time frame, but you won't see that happen... you'll see it after it burrows to top after 3-5 days. the extra steps of the paper towel method create opportunity for mistakes that cannot occur with the direct in substrate method.. .heck you could have passed along a pathogen from your hands to the tap root... seedlings are sensitive.. they will stop growing due to early stress... as if it just says, "i can't survive here, so i quit." anyway, give it more time... could just be stuck under a chunk of perlite and needing another 1 day to circumvent it before sprouting. you get up around 10-14 days and you can start worrying about it rotting in the substrate. keep it moist but not overly saturated early on (not good later on.. always awater entire volume of pot when properly irrigating a more mature plant)... dry surface could kill a seedling with a short tap root early on. it has to physically reach moist enough substrate, obviously.

Not sure if the heating box is working, but I remember I boiled a few seeds using it... (wait 2 or 3 more days and inspect the soil using tweezers for example, but they are gone IMHO)

I buried them maybe 1cm in the dirt and did try to make sure to not pack the dirt, but maybe the pre-watering might have made it too compact. Will can try removing a bit of dirt from the top, but any tips on how I can try and make sure the soil is loose enough? I can also be clear that my tails were not 1-2cm long, they were maybe max 0,5cm, but yeah last time using the same method and soil etc they showed above ground within 2-3 days so getting worried that somethings wrong.

Enterraste mucho las semillas? o apretaste demasiado la tierra? A mi me han tardado 2 días en salir pero si es verdad que yo las sembré cuando tenían ya una raíz de unos 2cm. Yo seguiría esperando o si crees que la enterraste mucho le quitaría un poco de tierra de encima. La semilla no debe de quedar muy enterrada (a 0.5cm aproximadamente).
