I checked fanboxes and there were sings for changes from previous tests. This mean i already tried different variations on this box. Just don't remember. This must be the best for them so i didn't make any changes.
I lowered the place where they'r growing and made the pots a little lower than before, turned big fans angle more to lamps. By doing all I managed to set general temprature to 26C (79F). Humidity is around %30-40.

1st gen. started their 3rd leafsets and tiny side stems are visible. Their roots coming out from the holes.
2 from 3.rd gen. germinated. There are 14 in total. But latest seedlings seemed little problems to me. 2 of them still trying to get up to surface for two days. Looks like they failed. Wait and see.

I'll mix water without TNTComplex (N:P:K 3:2:3) for this week. There is also PowerZyme, I'm going to give once today, or tomorrow to 1st and 2nd gens.
