I stand by my mentor:
77F/25c is the best temperature to grow
fall below 50% (33f/12c) the plants falls DORMANT (little growth)
likewise too hot the plant falls DORMANT or goes to sleep
as for genetic markers ...?
Gee! dna is all over the plant just as it is all over you and me,
vip:
a cutting is a cloned plant with no roots
as is a clone is a cutting until its got roots..?
I pity you trying to grow in chilly temps for 28 years
do you ever see any mature plants, do they ever finish..?
I agree to the fact, that there is far less (N) in those lower laterals
and perhaps more in the line of excess Gibberellins or even general hormone activity
sorry to diss you, I just find it hard to accept a grower of 28 years could 'discover' such a feat..?
perhaps you have a peer?
I smoked a lot of good weed in Jamaica and Colombia and it was a lot hotter than 77 degrees there.
