i would put the seeds flat on 1 inch rockwool cubes when the tap root is 1cm i would push it inside the cube
and put it back in the propagator for another day, i usually have them under the light on the nft within 4-5 days
of starting germination, it takes about 3 days after this for the tap root to grow out the bottom of the 1 inch cube
i then put this in a 3 inch cube, another few days later the roots will emerge out of the 3 inch blocks
i have found that seedlings will still grow into pretty big plants if they are flowered when the stem of the seedlings
has become thick from top to bottom this happens at around 14 days
for the first 8-9 days growth is very slow, between 10 and 14 days things really speed up
i would suggest it is a good idea to try 50/50 or 60/40 f1 hybrids and select the most vigorous sativa dominated phenotypes
rather than growing kali mist or something like that
you will get indica dominated phenos growing blue cheese but you can discard them and keep the vigours sativa ones
this was a cheese dom of blue cheese from dinafem, it got this big after 3 weeks of veg, it was one of the smallest seedlings on that current run before flower
some growers think that to get a plant big it requires lots of veg time, this will work too
but the alternative is growing sativa genetics, here veg time is not so important as most of the growing
will occur between weeks 1-4 of flower
growing hydroponically helps speed things up a bit and it may make the plant a little larger
however if this same plant were grown in a large soil container that allowed for plenty of rooting it would of ended up a similar size most likely would of taken longer and had a few spider mites lol
