"Semi auto" landraces?

[Rajas]

Are you sure? On the equator the day length only varies few minutes over the year it seems this is not sufficient to trigger flowering. Some of the equatorial Sativas have adapted by developing autoflowering traits. Ed Rosenthal wrote in the Cannabis Growers Handbook on Page 38:
“Most varieties of cannabis are short day/long night plants, with the possible exception of C. ruderalis and some equatorial C.sativa varieties that are commonly described as auto-flowering and may be day-neutral”

I was "researching" the topic of day length in relation to the start of flowering. I'm at 50° latitude and I'm searching for something that triggers flower between 16 to 15 hours of day length. I stumbled upon semi autos because they supposedly trigger early. Khalifagenetics answered an email about their Beldia and its semi auto traits. Early flower can be triggered by root space, poor soil and other stress factors. According to Khalifa their Beldia will start flowering below 15h45min of day length. I'm planning on making seeds in a tent this year and the idea is to just select the ones that start flowering at 15h30min of light and put the seeds outdoor next year an see what happens.

Its interesting because outdoors it doesnt work that way. I still dont understand Beldia's flowering modes eventhough I just grew it this year.
Outdoor it starts rather with deminishing light hours. Thats from End of June to early July. At my latitude its from the very start below 15:45 light hours. It then peaks at 16 hours daylight and goes down again. About 2-3 weeks later you see the first pistils. The plant grew being sexually mature under 15:45 hours of daylight for a month and no pistils, but after the peak of 16 hours and deminishing light hours it triggered. The plant was also at 1-1.3m in size when i saw first pistils - 1m size is also a trigger for flowering...
So who knows, i even had serious light pollutions yet it flowered perfectly till the end. This plant wants to start very early in the year to use all the strong sun for flower production, everything else is unfortunately not studied at all. I dont even find literature on that flowering mode. Schoolars ignore that topic.

Semi Auto landraces:

Sinai
Lebanese
Beldia
The landrace team as a few eastern european feral strains with semi auto mode
Zamal might have some phenos with semi auto trait but it is only confirmed by two people growing it here in the forum, everybody else seem to be suspicious about a tropical plant flowering like more northern varieties.
Baglung Nepal

As far as I understand it you find semi autos between very northern ruderalis and classic photoperiodical plants (latitude).

On the other hand somebody growing Mango Biche in Swiss said it started flowerin in summer. So there are some tropicals that start very early, too. Its just a matter of being able to grow unselected landraces in bigger numbers outdoors and pick those rare genes.

It's definitely intriguing the Beldia isn't auto it's photoperiod but it's just crazy early I suppose it's the most “ simi auto “ you can get. What is simi auto anyway,? I bet I can reveg a beldia cutting .I have a cutting from a Lebanese taken in mid flower rooted and looking like it's reveging now
