How long does a photoperiod take to flower?

The fastest photoperiod strains can be ready to harvest after as little as 7 weeks of bloom. Some of the fastest Dutch Passion strains include Bubba Island Kush and the legendary Orange Bud. In good conditions these are ready in 7-7.5 weeks of flowering.

Many growers aiming for a fast cannabis harvest enjoy growing autoflower seeds. Without a doubt, auto seeds are a fast and easy route to a straightforward harvest. But many growers still prefer the old-school challenges and rewards found when growing photoperiod feminised cannabis.

Some slow blooming photoperiod sativa strains, such as certain Haze varieties can take 14 weeks (or even more) to complete bloom. Yet the fastest photoperiod strains can finish flowering in half that time. Read on for more info about the key factors which influence the flowering time and understand why some cannabis genetics take longer than others.

Photoperiod cannabis plants average flowering time

Most growers find that most photoperiod cannabis strains tend to take around 8-9 weeks of flowering. Flowering time is mostly determined by plant genetics, but environmental factors can also play a large role. Indoor growers with sub-optimised grow room conditions (e.g. cold temperatures) may find that bloom is slower than it could/should be.

Most cannabis seed companies state the earliest flowering period for their strains, assuming optimised conditions. Some growers have a personal preference for early-harvested weed, conversely others prefer late-harvested weed which they may feel produces heavier effects. Your own personal leanings could determine whether the crop comes down earlier or later than average.

What is the fastest photoperiod cannabis strain?

If you’re looking for the fastest cannabis strain then it’s difficult to get much quicker than a 7-week bloom time. The two fastest in the Dutch Passion cannabis seed collection are the indica Bubba Island Kush and the sativa classic Orange Bud. Both can be ready in as little as 7 weeks of bloom. Remember, in order to get the fastest growth ensure that the grow room and environmental conditions are as good as you can get them!

What is the slowest photoperiod cannabis strain?

The cannabis genetics control the growth cycle and the length of bloom. Certain strain types such as specific types of Haze, Amnesia or sativa varieties can have long bloom times. The longest flowering strains, which includes some Haze varieties, can take 14+ weeks in bloom.

Such strains have often evolved to bloom at a leisurely rate in warm, tropical climates where the threat of a fast approaching winter simply doesn't exist. In general such long blooming strains achieve only limited main-stream popularity. They often remain popular with niche growers that enjoy the specific effects from certain cultivars. The following strains represent some of Dutch Passion's longest flowering photoperiod cannabis strains.

Desfrán, pure jungle sativa with lots of stretch and a soaring high

If you love sativa genetics as pure as then come, and don't mind waiting a little longer than average for flowering, then Desfrán is the perfect choice. Typical bloom time is 9-10 weeks. Indoor growers should beware that the stretch on this strain is significant. That may be a challenge for some growers but those that grow cannabis with the SCROG method should love her. The high is powerful, soaring and long lasting. One for the true sativa connoisseurs!

If the long list of photoperiod feminised seeds seems like a confusing choice, then you may want to check out the Dutch Passion online seed finder. This asks a few basic questions about your grow room and harvest targets before recommending the most suitable strains from the Dutch Passion cannabis seed collection.

Get the best photoperiod cannabis seeds in the market

Most growers only buy a few cannabis seed packs per year, so it makes sense to research the options carefully and select the best genetics for your personal needs. You may prefer to get a fast flowering variety for speed, but there are other selection criteria that are also important to some growers. Whichever cannabis seeds you choose to buy, enjoy the grow!

Top-5 best yielding cannabis seeds

Fast flowering times are important to many growers. But even licensed legal growers, whose main focus is often fast crop turnaround, are heavily influenced by other factors. High yielding cannabis strains are often highly prized, especially when they come with excellent potency and taste.

Cannabis cup winning cannabis seeds

So long as the final result is assured to be of truly memorable quality then many growers are quite happy to grow any cannabis seeds, whether that be autoflowering seeds or photoperiod feminised seeds. The list of 70+ Dutch Passion cannabis cups is professional industry recognition of some of Dutch Passion’s proudest breeding achievements.

Easiest cannabis strains for less experienced growers

Best autoflower seeds for quality focussed growers

If fast harvests, a simple grow experience, and high quality results sound like an appealing combo then you may want to check out Dutch Passion’s top 5 autoflower seeds. They grow from seed to harvest under 20 hours of daily indoor light in around 70-75 days. They also grow well outdoors and are regarded by many as the easiest way to grow cannabis.
