UI have never grown land race sativia... but I know how long it takes to flower them. Do you think possibly that people just can’t wait long enough for amber?
In the article, it said things like “may never turn amber†and “almost all whiteâ€. I’m not 100% convinced... but just because I have never seen it, doesn’t mean I am unwilling to learn.
I also know that a 12-12 light schedule can mess with a landrace sativa flower cycle. Check out the longer nights the places near the equator get in the winter. 12 hours of darkness may not be enough to force the plant into developing into amber, because that never actually happens near the equator in winter time.
Of all the sativia dominant dominant plants I have ever grown, every single one has gone amber at the end for me.
Sometimes when it takes way too long... I increase the hours of darkness to 10 on and 14 off. Or even 9 on and 15 off. After that...they amber up real fast on all strains I have ever grown.
In Durbin Africa (famous for the landrace dirbin poision) winter begins in June. The 12-12 light schedule happens for about 2 weeks in March. The remainder of May through winter gets significantly less daylight hours.
So if you grow this landrace sativa strain and are doing the traditional 12-12, the plant is still experiencing the same duration of time as end of summer in daylight hours.
