i´ve read that you should not start to flower sativas before they´ve matured (ehh, whats it called, when the stems dont grow side to side anymore?)
since , its the the premature flowering that makes them hermy. (as in "oh shit, im starting really late, better make some insurance balls
")
and so far, well, i aint seen no hermying.
on resin, you wont see any crystals or resin for the most part, curiously sativas dont tend to display that.
you can speed up flowering with a 11/13 flower cycle.
still, probably gonna take 1.5 months to begin to flower, (and thats after maturing the plant first)
about buying in vietnam, well, id make some friends first, i would not try to buy off the street. the cops are rather brutal to boot. but its a very nice place really, good people and cheap to live there.
reminding sorta of a more tropical spain in looks.
the flowering, the plants i saw out there, hehehe 6 feet tall with hardly any buds (tiny) and i didnt see any change in the plants to speak of the 2 times i saw them (month apart)
id. do either scrog or sog, if i was gonna do this strain alone.
with sog, then a ton of tiny plants all started flowering as soon as roots showed.
but, your instincts are on the button, as far as ive seen, these strains seems highly suited to scrogging, specially if you top them at the 3rd node (automatically creating 4 tops)
and create many many branches.
(btw , international canna graphic, the forum, has quite a few more pure sativa growers and is the site i would go to for more information, though, bricktop and i probably have told you most of the info.)
