hi Sabrina,
are they outside or in the house?
I don't know about the north of Italy, but over here it is definitely getting colder and the days are getting a lot shorter .
I'm a first time seedling-mama as well
so I'm not 100% sure, but I guess those are the reasons your (and mine) seedlings are slowing their growth.
I think if they are put in a warmer place and/or (?) under a growth lamp they would start growing again.
I was wondering myself how in a seedling the impulses for growing and going dormant (if it is that type) work..
Will a seedling go dormant under the 'right' circumstances and resume it's growth in Spring?
And will the 'food' that is stored in the seed still be ok at that time?
Sabrina, do you know if the parents of your seedlings are dormants?
edited: I don't grow my seedlings in vermiculite, but put them in earth as soon as they sprout.
Also I feed them once a week with a diluted liquid fertilizer, so they get an extra boost here.
It will be interesting to see whether that all makes a difference. :-)
