i start this grow abut 8 day ago
i made some experiment:
i germinate 2 seed 1 big and 1 small and moved them to 4 inch Rookwool
the small one show some progress to but it mach slower ( i help him today to get reed off the seed shell )
the big one show good progress- the roots are get out from the Rookwool
by the way i didn’t apply any water solution on the Rockwool before using them and it is seem that the are ok.
i see that the roots are white color except one root that his ending is brown
what could it be ???
there is an option that root can be damaged from air (no light) ???
