What are fast-flowering cannabis seeds?

Fast-flowering cannabis seeds have photoperiod growth traits but shorter blooming periods. They reach peak ripeness two weeks before their standard cousins.

This strain category crosses elite light-dependent cultivars and autoflowering plants. The trick lies in its recessive ruderalis genes.

Fast plants remain photoperiod but borrow speed from ruderalis. Flowering shortens because they expect an early winter, and the nugs are harvest-ready in 6–8 weeks. Vegging lasts till light flip, though, letting you manipulate the total seed-to-yield period.

We can cross regs or fems with autos, but the latter is more convenient. Our fast seeds are all-female, reducing the risk of rogue males, accidental pollination, and harsh buds.

Why grow them?

Cultivators love fast-flowering weed seeds because they’re:

  • Larger and higher-yielding than autos: Non-photoperiods are a boon for time-limited growers, but they remain small and don’t often produce heaps. Fast plants can get considerably larger and heavier.
  • Faster and sturdier than photos: While growing the same as your favorite fem, a fast cultivar will become harvest-ready earlier. You may sow it almost anywhere with minimal fussiness, too.

Growing them entails these benefits:

  • Complete control of plant size: Flip to flowering early to keep plants small or prolong vegging to increase their size and productivity. The choice is yours.
  • No fall weather problems: October rains and chill can harm marijuana in the sensitive late-flowering stage. Fast cultivars are ripe and ready in September.
  • Original flavors and effects: In autos, ruderalis makes plants somewhat weaker in taste and THC. Fast cultivars retain the original qualities of their long-flowering photo parents, though.

Do fast-flowering cannabis seeds have specific requirements when growing?

Is it harder to raise seeds that grow fast? Will you be trading ease for speed?

Not at all. Some fast cultivars can even be more straightforward than their standard cousins. Ruderalis lends sturdiness to this type, reducing the time and effort invested.

The precise growing requirements are strain-dependent, but let’s discuss the broad strokes.

Should you sow in soil or hydro? Whatever you like.

Speedy seeds have no particular preferences, so look into your strain to see what it likes best. As a rule, organic soil is for cultivators with a hands-off style looking to avoid nutrient troubles.

Hydro suits folks who want to boost their yields with careful control.

Indoors or outdoors? It depends on how soon you want to harvest.

Since fast cultivars are photoperiods, their life stages change with the amount of light. Plant outdoors for a long growth period and pick an indoor setup if you’d also like to shorten vegging.

What about nutrients, water, and light? Whatever the cultivar enjoys.

Stick to the photoperiod-style basics in the vegging stage, as nothing changes with seeds that grow fast.

When flowering comes, increase the light to supercharge bud production. Remember to flush two weeks earlier than usual for the cleanest flavor.

And training? Feel free to practice your technique of choice.

High and low-stress training is a veg phase process, so there are no special considerations with fast seed-grown plants. Stop the manipulation when they bloom, and you’re good.

How long do fast-flowering cannabis seeds take to go from germination to harvest?

Sow a batch of our fast-flowering cannabis seeds, and you can collect ripe, resinous buds in 2–3 months. Or wait longer to get more weed: the seed-to-yield duration is totally up to you.

Here’s what you can expect from our quick cultivars:

  • Germination: 1–5 days
  • Seedling stage: 2–3 weeks
  • Vegetative stage: 3–16 weeks
  • Flowering stage: 6–8 weeks

FAQ


The Seed Fair has the Blue Amnesia Autoflower Seeds with a flowering time starting at six weeks.  When you grow indoors, this plant will yield about 600 grams and is a perfect seed for beginners.


The Big Bud Fast Version Cannabis Seeds are one of the fastest flowering strains that The Seed Fair carries.  These feminized, photoperiod strains are easy to grow and perfect for beginners.  This Indica dominant strain provides a quick and lasting high.


Marijuana seeds of autoflowering varieties are among the quickest growth rates.  Their entire life cycle can occur during the same period that other varieties are just the beginning to enter the flowering stage.


Indica plants on average, mature more rapidly than Sativa plants and produce a greater number of buds.  Sativa may mature slower than Indica, although it may grow taller, be more slender than Indica, and have slightly higher THC levels.


The flowering time for feminized seeds ranges from eight to nine weeks, meaning their growth rate is slower than that of other marijuana seeds.  You can cut that time in half by experimenting with the lighting if the plant is grown indoors, but you should only grow feminized seeds if you are an experienced cultivator.
