Thanks Chomp, would be lovely to do this with a 600 watter
Well, as far as I can say they all look like girls to me, of course there's possibility of intersexed plants later. All have similarly shaped preflowers, that look like calyxes to me, 2 of them are pushing white hair out of it barely. Hurts to try to see it with bare eye, but loupe helps. Since they bit big for my bulb, probably gonna do flip and take cuts pretty soon. Oh and tranplant too.
Edit: Plants after transplant, some trimming, training and so on adjusting in the next few days
