The fast finisher are..
JLP's Mississippi Mud..
and a White Widow Blue Mystic cross.

On the ww/bm cross..I got 2 FF girls..
and 2 season long girls.

On Jlp's Mud..I got 1 FF..and another.

All seeds were grown at the same time in the same conditions.
I have 2 season long girls as well..so I have a test.

In good conditions AF's show sex between 21-25 days.
The FF show up about 28-30 days.

Af's go straight from sex..to starting fat buds..
Season long girls..show sex..then grow with still thin bud..then start fattening bud.
The FF's went straight to fat budding..the same as the AF's.

Photo dependency..
I harvested the AF's & the FF's around May..
FF's came in around 2 weeks behind my AF's.
increasing natural light pattern...so they don't look photo dependent.

I DID worry that because I was on about a 14-16 hour natural light pattern..
that I had forced the FF's into flower....(12/12)..
but discounted it..as it would have also forced the season long girls too..
and it didn't.

JLP's Mud..FF


WW/BM..FF

Very interesting mossy, thankyou!

Im from Denmark where we have long vegetative and a short flowering period.
This summer we had lots of rain but with good, early and mold resistant genes, a lotta care and good nutrients we still manage to grow some good cannabis here, although most of the exotic sativas can only be grown indoor or in versions that has been climatized here for many years.
Im on 56N
heres the day length for 55N all months of the year.

good thread! thnx BACKCOUNTRY bro for useful info! bump

Hello,

I have grown hemp plants from pound packs of bird and fish feed. These F2 plants have few resin and are mostly hermaphrodite.

Germinated on the window-sill of an unused, cool room in February plants sexed two months later and did neither look nor smell too shabby. The raising daylength had its share in stopping sex and delaying seed maturation. In June when seeds were ripe and plants transplanted to the outdoors they re-vegetated. In August they sexed again but looked ugly and moulded away soon after although the weather was nice. Thesis: "Grey-mould does not depend on rain and humidity but on plant sickness. Healthiness is mostly determined by the phases of genetic expression and by the state of roots."

Plants started in May outdoors were ready for seed harvest on September 1st. (But hermaphrodites grew grapes of pollen sacks that dense that the inner sacks could not open. These grapes clung to the plants still at harvest date. The F1 seed parents may have been hybrids which did not show this excessively stupid behaviour.)

Therefore this strain called Macks Futter starts to flower if:
A) it is at least a month old and the days are short
b) Or when it is at least a meter high and the solstice with 16 hours of sunlight has passed.

Cannabis Sativa Sativa, the european fiber and seed hemp, is sown in May and harvested in September.

F3 plants started in June were all males and done in October.

Another strain called Wehrens Futter is in heavy flowering right now and should be ready before October. The males showed much earlier than the hermies and I do not even know if there are any true females. Hermies look better than the ones of Macks but are slim, say low-yielding.

Ruderalis Indica did not show much daylength-independant flowering. Only one plant started to flower after transplant but fell back into vegetation soon after. Right now they are two meters high and still bald. I read that even Lowryder does not flower reliably in german summertime. Some finnish growers have got the knack of auto-flowering; certain environmental conditions as for instance the type of soil probably help. Although humus of needle tres may look similar to the one of leaf trees the chemistry is different. It is hard to convince Cannabis to flower on long days and certainly a recessive thing. Auto-flowering depends on warmth (May and later), growth (good lighting and watering) and youth. The youth factor can be great but varies greatly due to yet unknown reasons, too.

Luise of bagseed had a lucky lifetime from March to October and was already resinous in August although the summer had been miserable. Shiva Shanti which was germinated in end of June and grown in the ground sexed in August and matured in late October. Flowering a cutting of a big outdoor plant alongside a small seed-plant indoors it becomes clear that the seed-plant lags behind. All else being equal, the sowing date has a slight positive effect on possible harvest dates.

great info!

somewhere around here a guy took a picture on his trip to pakistan(or someplace) and it had a sativa flowering before the indica planted next to it. so i think the whole when to flower thing can be highly genetic and with enough breeding most anything is possible.

Hi all, nice thread. I'm in the 45.5 and seen something special this year with a local strain. M39, a quick to finish (45 days) photosensitive strain. Planted very very late around mid-July. Wee-little clones 6" appart in a patch. A sea of green outside. We'll see how they do and I'll let you all know. Usualy here this strain is planted in 6" pots and put in flower 1 week max after transplanting from clones. This gives off great yield per square meter. The theory is that moving them from indoor 24h light to outdoor 15h light will trigger immediate flower and cause the plant to go on overdrive like they do indoors. This kind of contradicts what has been mentioned above but with the combination of cold nights and shortening days I think it will work. Anybody out there tried anything of the sort? Anyone know how much of an effect the cold has on triggering flowering. What about the effect of shortening days, would that not make more of a difference than the actual amount of lignt per day?

Hi there! Are you saying these plants are inside or outside right now? It sounds like you are saying they went out already, if so....when?

As I recall, M39 has also been available commercially for some time from the same breeders that supplied Mighty mite, but it seems to have disappeared again on the market. Perhaps you live in the part of Canada that this strain originated in?

I can't see how your experiment would contradict anything said in this thread.....
