Who is the liar?

I think the more accurate estimate would be this, from their webpage on the product, despite it being in the indoor guide for it, it will be the same for outdoor. " harvest around 7-8 weeks after flipping the cannabis light cycle " https://dutch-passion.com/en/cannabis-seeds/gmo-fast Its all based on when the plant enters its flowering phase. and it will be 7-8 weeks after it flips. External light sources can mess this up. so flood lights, street lamps, flashlights, motion detector lamps. My outdoors had so much light pollution I can only grow autos outside or they all hermi and don't grow well. Fast just mean it can finish a week or two earlier then regular not fast plants. Its a gimmick and not worth buying IMO. Just grow autos at that point, they finish early regarldess of lightcycle.

You bought seeds, not a full life support that tells you how to breath. I would probably also, after the snapshot of your behaviour i got here, just silence you😂

It depends a lot on where you are and how much light the plants get. The further north you are, the earlier it will start to flower, but can also depend on if it's on the north side of your house in the northern hemisphere and has the days cut short from shade. In the southern hemisphere, the season is completely opposite, and we harvest in April/May. Some years it can be a bit earlier or a bit later in the same location. There is a lot of variables growing outdoors and the specs of the plant should be taken as a guideline, not gospel.

The ones taking your money, obviously... Just as "fast flowering" cliams are mostly lies. They all do it. Breeders lie about how long it takes and how much it will yield. Light producers will lie about their techinical details of the light. Fertilzer producers blow smoke up your ass about what their products can do.

You must be really lucky to get the plants through with the crappy weather in Germany, I almost doubt it unless the strain is mold resistant, then it might be doable.

Every seed bank always embellishes their information, it's clear who the liars are... since the seed bank is Dutch, the outdoor conditions are pretty much identical to Germany, so the information should be provided under similar conditions. But in the end, the plant itself decides when it realizes that the sunny phase is coming to an end. What do we learn from this? Never trust information from seed banks, use it only as rough guidelines... at the end of the day, the plant adjusts to a life cycle that is shaped by sunlight intensity and availability. If the plant, for example, still gets a lot of sun in September/October, it hasn't yet realized that winter is about to start, and the hormonal change comes accordingly too late.

When growing outdoors your flowering times/harvest period will largely be dictated upon where you live, aka how and when light cycles change enough to promote flowering. Especially if you're growing a sativa dominant strain with a long flowering time, you gotta keep those sort of factors in mind. You're right that your plant still has quite a ways to go but that doesn't make Dutch Passion a "liar" either.
