How To Speed-Up Cannabis Flowering And Harvest

There's no dread like wanting to get high and having no bud, and that pain is even deeper when you're growing it yourself. It's there, but it's not. You know it can't pop up overnight, but you may wish it'd pop out of the ground a little bit faster. If you find that thought running across your mind, it may be worth considering fast-flowering cannabis strains for your next harvest.

Before buying fast-flowering seeds, though, you'll want to consider the nitty-gritty details of these plants and consider their pros and cons. From there, if you're interested in growing some yourself, you can consider a few of our personal favorite fast-flowering strains.

What Are Fast-Flowering Cannabis Strains?

What Are Fast-Flowering Cannabis Strains?

All cannabis plants follow one of two flowering patterns: photoperiod or autoflowering. The former need a particular light schedule dictated by the seasons in order to bloom. Autoflowering strains, on the other hand, will progress with flowering regardless of how much light they’re given. Fast-flowering strains have a little bit of both in their genes.

The process starts when you cross a photoperiod-dependent parent with an autoflowering partner. As plants pollinate and seeds are produced, the autoflowering parent passes on key recessive genes that speed up the flowering phase. Essentially, you end up with an express version of classic photoperiod genetics. What you’re left with is a strain that flowers—and can, thus, be harvested—faster than typical photoperiod varieties.

Advantages And Disadvantages Of Fast-Flowering Cannabis Strains

There are many reasons you could want faster-growing plants, whether you need to avoid inclement weather or manage multiple harvests in a season.

Advantages

Advantages Of Fast-Flowering Cannabis Strains

No matter your situation, fast-flowering strains have their advantages.

  • Faster grow time: Fast-flowering strains can be harvested between 1-5 weeks sooner than classic strains, which also means you can grow more often.

  • Thrive in any weather: Fast-flowering cannabis can be grown in places with adverse weather conditions, but also excel in warm temperatures.

  • Fewer fungal issues: Due to their rapid growth, FF cultivators can avoid problems usually associated with damp and rainy autumnal weather.

  • Safety first: Due to the simple lighting schedules necessary for quick strains, there's a lower risk of safety hazards.

Disadvantages

Disdvantages Of Fast-Flowering Cannabis Strains

On the other hand, there are also disadvantages to using fast flowering strains you should take into account.

  • Smaller yields: Due to rapid production, yields from fast-flowering strains are smaller than classic and autoflowering strains.

  • Lower cannabinoids: For similar reasons, buds from fast-flowering plants usually have lower cannabinoid levels than those from classic photoperiod strains.

  • Beyond that, there aren’t really any drawbacks to these strains. Not only that, but most of them can also be negated by implementing the sea of green method.
