lights arent gonna help right now... I forget how many u said u had sprouted (and too lazy to look back) but if it were me Id get em on that heating pad and take one, get a pencil, chop stick or something of that nature and lightly pull away a layer of soild at a time to see if anything is happenin...lookin for a long white tap root not the seed itself... if the seed is ontop or near the taproot your still in lck and just burried em too far if you see tap root in an arch and the seed casing looking like tis growing down instead of up you got probs....try to gently lift the seed casing side so its pointing up. Ive had some break the soil arched but I dont bury that deep... how deep do u think you burried yours?
