hi chrille grows,
Cannabis belongs in group of 14hours light flowering plants.
12 hours was taken because its shorter in nature, same as 18 what is longer.
Canna will react on 14 hours and start preflowering (pistils) whats count in flowering.
Depends how much an strain have autoflow genetics it can be flowering on 18 hours of light or 16 hours.

I dont know where you got that numbers for sunlight, but if twilight are in it than its right numbers.Plants react on twilight, about 30min before sunrise and about 30min after sunset.

Not sure for Purple Moroc and Moroc but I planing to transplant them outside in May what is about 15:30 hours of light.
They might start preflowering but in 15-20 days they should back into vegetation.
Im warned on grapefruit (not outdoor) but GF didnt start preflowering in May, but at end of July wehre he start to flow but not really until mid of Avg.

BUT you are on 60 and me on 45 ... not sure how it works up there, but Im guessing begining of Jun should be OK.

Many people seem to misunderstanding me here. I only want to know how Maroc, Purple Maroc and Easy sativa if they could begin to flower with these rapidly descent of light hours or if they only flower when the dark period is exactly 6 hours. And i have to say also that up here where i live we have a very weak light around the hours when the sun rise and set and i wonder if i could count away those hours just because its so weak, because Female seeds say that these strains could flower even in the shade(=low light cond.) so that is the reason i want to know if the less intensive hours of sun could do it for them ? And we dont have like you other people further down in the south like it is a little light for an half hour before the sun rise, here it could be for 2-3 hours before the sun rise or sets and during that time it is a very weak light.

Yes the rapid decrease in daylenght will trigger flowering.
Get good spots = happy harvest.
Either pre veg indoors from march and grow huge trees or start them 2-3 weeks before midsummer and plant them outdoors at midsummer, then they only see decreased daylenghts and are triggerer by that.

They never worked for me at 55-56lat so your answes no, too far north.

Well the easy sativa have worked for me several years in a row so either i get magic beans when i order or you are wrong...
The spot you choose for growing is alot more important then a couple of degrees up or down.
Combine this with useing the fact that the plants flower because of their age not just daylenght only.
Check around the outdoors part of the forums and you see plenty of people that grow nice crops in Canada, Sweden, Finland and so on.

Can you tell me more about this ?
I mean since when for photosensitive plants trigger arent light/dark ?

I´m a little confuzed when i read some threads here at the Female seeds forum. Some people say Maroc, Purple Maroc and Easy Sativa can be vegged at 18/6 and some say that they will flower on that and some people say that 22/2 or 24/0 is the only way to keep them in veg so i wonder if anybody knows for how long are they naturally vegging before entering flower if you have them outside ? I´m trying to find out if they flower after a while regardless of how many hours of light they receive and if they would flower if the light decreases fast although it is still only 4-5 hours of darkness ? All you people who has growing these strains let me know your experiences. . .

That's indoor growing buddy! Outdoor growing is quite different as some here have pointed out. I don't know your level of experience but even if you've been successful in the past, it's not due to the reason you stated above. Check this thread out from BACKCOUNTRY, it's a sticky in the outdoor forum for a great reason. . . it's all true! Post #4 deals with what you're talking about.

I just received my first pack of Maroc seeds today, so although I can't speak from experience I looked into the strain quite a bit before making the plunge. From what I can tell, most people are growing Maroc because it does well outdoors is areas with short growing seasons. All the reports on this site confirm that it's finished by early to mid September & the final product is of a quality rare to plants with comparable short seasons.

The Female Seeds description says:
"We wouldn't recommend pre-growing them indoors, because they are semi-auto-flowering and this would cause them to start flowering in May outdoors. They need the longer days and intensive midsummer sun to keep them in growth.

For the warmer/Mediterranean climates we offer outdoor strains with a very high flower to leaf ratio. (more flowers than leaves, rock hard buds)"

Now, I don't know exactly what "semi-auto-flowering means," but it also says, "they need the longer days and intensive midsummer sun to keep in growth." I'm certainly no expert, but a true auto-flowering strain flowers due to an internal clock, not the changing of the sun's duration/intensity (which is pretty much the definition of a regular strain, right?).

For what it's worth, I took all this to mean that the strain is a little more sensitive to a decrease in the light intensity/duration than most strains. Some short-season outdoor strains can be placed under a 1k HPS and vegged in 5 gallon buckets for a few months before being placed outdoors in late May/early June. The benefit of course os having a larger plant come harvest. I personally would love to do that, but it doesn't sound like this strain would like going from 24 or 18 hours of light with a HID light to the shorter days of less-intense spring light very much. It might start flowering before you wanted it to, therefor accomplishing the exact opposite effect that vegging would normally have, producing larger plants.

I personally am growing at about 48 degrees N & I am planning on starting them under a T5 fluorescent fixture on April 20 & putting them out on June 1. With that schedule I think they should be fine, and I expect to harvest around mid september, but can go as long as October 1 if necessary. I think you will be fine with this strain in Sweden.

Good luck!

I don't think it's a true autoflowering strain. When researching it, I didn't get the impression that the # of hours of light is what mattered, so much as the fact that you can't let a plant get too big (and therefor become sexually mature) and then drastically change it's light regime. As I stated above, I think they say this because they want people to know it won't pay off the veg them indoors ahead of time. I PM'd two different IC members who both assured me they had kept mother plants for over a year.

I found this encouraging because it meant they hadn't experienced any true auto-flowering traits, but they also thought it was good enough to keep a mom around all year in order to grow it again! Must have been good!

Your best bet are TRUE autoflowering strains imho, i dont think that FMS strains can flower fast enough before the cold at your latitude.
Anyway each zone has his best strains breeded through the years so check out local growers, i know for sure that up north there a lot of interesting AF crosses (stuff like Pehkruder or Typhoon comes to mind). Ask Esbe for his earliest strains.
