ive said it before but i dont agree with all these (most are ridiculous) germination methods. put your seed into damp soil (rockwool for hydro) and wait. if it pops your onto a winner if not it would have probably been a shit plant anyway lol
mother nature made the seeds to be planted that way. im sure years ago they didnt drop them into shot glasses then leave them on damp paper for days then meticulously plant them tap root down. plants use gravity to determine which way the roots grow. even if u put the tap root reaching for the sky nature will correct it and make it grow downwards and outwards. its in their genetic makeup.
just my 2p
