Auto Flowering

 AUTOFLOWERING SEEDS

We offer a selection of the very best autoflowering seeds, each guaranteed to germinate and produce strong, stable female-only plants, capable of flowering regardless of the number of hours of darkness they receive.

Unlike traditional seeds that require set, regular hours of darkness to flower, bud and mature, autoflowering seeds grow and flower simultaneously, reducing the overall time from germination to harvest to an absolute minimum.

The heaviest yields and best quality buds are achieved during the very height of Summer, when the plant receives as many hours of natural daylight as possible. Their ability to flower, even under twenty-four light makes them a perfect outdoor choice.

The highest quality genetics ensure discreet, compact plants, capable of quality harvests in the fastest time possible. The number #1 choice for ‘guerrilla-growers’ across the USA during the Summer months, with guaranteed delivery and germination assured with every purchase.

Whether you’re new to growing or a seasoned veteran, you can buy Marijuana seeds online and receive all the help and support you may need from purchase through to harvest, here at Marijuana Seeds US.

Naming

As of January 2020, online vendors offer more than 1000 autoflowering strains with Sensi Skunk Automatic [8], Amnesia XXL Automatic [9], Big Bang Auto [10] and Zkittlez Auto [11] being the most sold varieties in the market. Most of these strains can be identified by the presence of “Auto” or “Automatic” (such as with the Gorilla Cookies Auto bred by Fast Buds [12]) in their names.

Advantages

The newly produced strains of autoflowering cannabis have proven that they can produce quality medicine comparable with classical short-day strains. Breeders have reported THC content around 25% in some newer varieties while many varieties also have high CBD content.[13] The advantages that autoflower breeders report with their plants include:

  • Short life span with many going from seed to harvest in under 13 weeks (some as short as seven weeks)
  • Can be kept short in stature for “stealth” growing
  • The Cannabis ruderalis heritage causes flowering after 2–3 weeks from germination
  • No need for a separate vegetative and flowering environment (unlike with photoperiod dependent/ short-day strains)
  • Simple seed production, one plant can produce several hundred seeds even at 1 foot (30.5 cm) tall
  • Due to short life span can be grown in cold climates where summers are short and cold[14]
  • Can produce multiple harvests outdoors in one season.

Disadvantages

Creating true autoflowering seed from two quality, true breeding autoflowering parent plants is easy for most.[16] Breeding new strains becomes more difficult when attempting to make a hybrid with a non-autoflowering strain. Some photoperiod/short-day cannabis strains are heterogeneous – containing the recessive day-neutral or  genetics along with the dominant short-day genetics. However a proper list of such strains is not yet available so most breeders treat all short-day plants as homozygous dominant.

A true autoflower is homozygous recessive[17] for the day neutral genetics. Therefore, most crosses between classical photoperiod/short-day strains and autoflowers produce few or no autoflower progeny in the F1 generation. Regardless of whether the F1 generation produces autoflowering plants, the higher performing and similar plants need to be recrossed. This F2 generation will contain approximately 25% of homozygous recessive plants which are autoflowering. Still the few autoflowers produced are not always stable and may require further stabilization. Further complexities with stabilizing  has previously led to non-autoflowering and low quality strains making it into the market.
