I am also into revival of old seeds
and I am using GA3 also, it all depend
on the % of the GA ppm my first try was
200 ppm it was too strong they did just
My next try will be 50 ppm its suppose
to be the best for seed soaking.
no need to soak overnite most of the
time its too long.
as soon as the seed sink plant them
I have a few G13 x Jackherer done with that
