There are a handful of strains that the breeder information says 105 day ... 15 weeks ... and longer .... but one run of Panama Red WAY back in the 70's took 22 weeks. I don't know of anything today that is available to the public that would take that long ... which even if there was I doubt many people would ever be willing to give it a try.
Here is an example of one of the 105 day strains.
Afropips Seeds - Malawi Gold

Malawi Gold is internationally renowned as one of the most potent psychoactive pure African sativas.
Afropipss Superior first grade Malawi Gold was selected from 10 years experience with top Malawi growers for the spiciest taste & the most psychoactive clean vibrant high. The high is long lasting & has an enjoyable alert mental clarity coupled with a warm pleasant feeling that radiates throughout the body.
The unique tropical & luxuriant spicy sativa up high can be attributed to the presence of THCV in this early cultivated strain.

Here's one that's 150 days, that's close to 21 1/2 weeks ... but I have no idea where it can be found.
Breeder Choice Organisation - Colombian Black
Strain: Colombian Black
Breeder: BCO
Location: indoor,
greenhouse
Type: sativa
Flowering: ~150 days
No feminized seeds.
Field collected in December 2002 from farmed Local lines in the 'llanos orientales' region in Colombia by Breeders Choice member 'Aldous'.
The original seed lot received from Colombia is being stored for future open pollinations of the line for preservation purposes and the selection of exceptional single plants for ongoing breeding projects.
This seedlot is a first generation accession with selection only against inter sex plants found in the line.
Black Colombian is a seedline native to the eastern plains (llanos orientales) region of Colombia.
The 'Black' is a pure Sativa genotype typical of equatorial latitudes, the 'Black' was very likely was brought to Colombia by African slaves. Evidence for this origin is suggested by the presence of a distinctive anise/black licorice flavour detected in the smoke of its blackish green to pure black flowers.
Other similarities to African genotypes include a relatively mild body effect and a more pronounced clear, positive mental stimulation that renders the user extremely happy within the moment.
As an adaptation to an equatorial environment the Black matures its buds in several harvest 'windows' with the earliest from our test grow coming in at 15 weeks, the next coming 5-6 weeks later.
Seedlings show minimal variation. True to usual form the largest, fastest growing seedlings often show sex as males at 5-9 weeks of flowering.
At 15 weeks the buds can began to take on the black colouration. True black, not purpling derived from cold temperatures. Although not all plants display these traits, some will.
Should the gardener desire to get the Black to wind down budding to harvest as early as possible it is recommended to move the timer to an 11/13 light schedule or even 10/14.
Due to such long flowering periods it is recommended to use fertilizers sparingly in both amounts and frequency of application.
The Colombian Sativas within the Breeders Choice lines all have aggressive root system growth thereby indicating a need for a larger than normal container.
A smaller pot size that 'rootbinds' the plant can help shorten the bloom time but if used the gardener should realize this as a stress vector that could encourage a hermaphroditic response in a proportion of plants. This is a first generation Tropical Sativa and should be grown with sympathy.
Our sampling left us extremely pleased with it's dark licorice taste and strong 'creeper' effect with a strong and ceiling less high without any noticeable physical effect, indicating this is a high THC low CBD Colombian cultivar.
An extended cure was required to soften a somewhat harsh initial bite. After 4 month's of glass jar curing, not only was the harshness mollified but a noticeable increase of potency accompanied the now full flavoured, smooth smoke.
In repeated smoke tests the most pronounced effect was a delayed creeper onset of high energy mental stimulation - without any noticeable edges of paranoia or discomfort. What physical effect there was can best be described as warm and composed with minimal raciness in heartbeat. Ideal for daytime activities and musicians.
A true, pure equatorial Sativa with no ceiling, never hybridised and a classic breeding line proven in other BCO Hybrids such as the Black Haze.
