Slighty more sensitive seedlings than usual, they doesn't seem to like much too high humidity early on.
- one seedling not sprouted after transplant (joint between root and cotyledons broke with humidity) and had to replace with some back up seedling
- one seedling sprouted with wound over cotyledons and first leaves stages, at this point not sure if it gonna recover or not
( last back up seedling is also a little wounded and appeared to have a weaker tiny root and slow growth as for now, all in all it may happen i replace one blackberry with one northern light clone within the two next week )

@ROM101, hum, that's what it look like this morning:
cotyledons are wounded, partially ate by some sort of fungi/mold that's now dried
first stage is heavily wounded : misshapen / small growth
2nd stage seem born dead / non existent
3rd and 4th leaves stages seem to grow at the same time
it's still to small to take a photo, but it appear to start recover after 8 days
@ROM101, yup that's the plan ^^
the back up seedling is slow growth for now (visibly weak young roots on transplant)
and the wounded one ( some sort of fungi parasite on start up) seem to directly split in two after first stage (still a bit unclear what happen yet, it's still so tiny not really with any clear shape or coloration, i mean there's no second leaf's stage clearly showing yet)
i'll try to do a macro shot with my cam, when thing show clearly enough with the heavily wounded one (but so far it's way too tiny, even for a close up shot with my cam)
@ROM101, thks, sensitive seedlings:
8/9 sprouted and 2/8 are unhealthy with wounded first stages and/or slow growth
after 7 days, not sure yet if the last two gonna recover quickly enough to fill the 7th slot or if i ll have to replace one blackberry with one northern light clone
@ROM101, prolly a strain wich seedlings doesn't like much too high humidity
- one seedling broke because young root was more looking like weak translucid blob full of water than classic resistant white root (replaced that one with the first healthy back up seedling)
- second back up seedling young root's looked a bit red/browny and really small like between mold and growth once out of cotton (that's currently the one with slow growth in the plastic glass)
- and finally the one were it seem some sort of fungi ate part of the cotyledons and young main stem and leaves before it get out of soil.
6 other seedlings are fine, but well it remain 9/9 germinated, 8/9 sprouted, 6/8 healthy
@Excalibur, thks, tight, true that's all about SOG & having as many main long colas as possible ^^
😂 ah, yup the fan totally that, cheap drugstore fan, but does it job well strenghtening young plant and dissipate lamp hot spot later in flowering 😉
