I am growing romaine lettuce in a HPA system. I am about to begin germinating, which I will be using partially submerged rockwool media under a 24h light. I was wondering if anyone has experience transplanting the germinated seedlings to an open root setup once they are in the aeroponic system, as I am worried they will be unable to adjust to the change.
I am also curious as to where the cutoff point for germination was for you; aka how long/how the roots looked when you decided it was time to move them to the HPA. Thanks!
