Lightning Autoflower

Autoflowering plants are revolutionizing the future of large-scale hemp cultivation

75 days from germination to harvest, plants can flower under mid-summer light conditions, allowing the farmer to shape their cultivation and harvest schedules.

Distinguished Traits

75 days from germination to harvest.
Not dependent on light conditions to trigger flowering.

Ideal for creating staggered planting and harvest dates.

This variety helps to increase “bud to stem” ratios by 30%+, due to compact and effective bud development.

Assists in the conservation of time, energy and general resources such as water, nutrients, labor and processing infrastructure.

Highly drought resistant, these plants thrive in dry stressful conditions.

Low water consumption helps to mitigate resources for the first 30 days, though the plants maintain very high metabolic demands throughout their short life cycle.

*Trimmed flower. Homogeneous samples will meet federal regulatory compliance.

Results are dependent on a variety of growing conditions, especially the harvest date. It is suggested that as harvest approaches, you have samples analyzed to determine the optimal harvest window and to ensure compliance. See our COAs for more in-depth harvest results.


  • Autoflowering varieties require a bit more care and attention shortly after the germination period. Due to their Ruderalis genetic lineage, plants optimally thrive in drier conditions with intense sunlight. High density planting is recommended to maximize yield potential as yield may vary contingent on your geographic location and time of year you are planting. Typically, autoflowering varieties can be more susceptible to shock in low temperatures (50 degrees and below). It is recommended to evaluate annual variable weather conditions before choosing when to germinate seeds.
  • Hot and arid desert regions typically can start spring germination in the end of March to beginning of April, depending on the season’s variable weather conditions and predictions. Northern regions are encouraged to wait a few weeks after the last frost to avoid any unnecessary lower temperatures, which can cause adverse effects during critical weeks of the vegetative period.
  • Plants typically show signs of flowering just 30 short days after germination and will continue to grow vertically 45-50 days into the life cycle. Soil should remain on the drier side as plants thrive in more stressful conditions causing more vigorous growth to occur. Small amounts of water given multiple times a day is the most effective method of delivery to create optimal growth potential.
  • Stronger feeding regimens are highly recommended to meet the plant’s aggressive metabolic demands due to a short life cycle. This is critical during the first few weeks of development allowing plants to gain necessary vertical growth for later stages of flowering development.

Did you know?

Long before breeders began modifying plant traits, autoflowering cannabis already existed in the wild! This unusual gene first occurred as an adaptation to environmental conditions. You might be familiar with Cannabis indica and sativa. Well, the autoflowering gene arose in Cannabis ruderalis .

The ruderalis subspecies adapted to the cold and often harsh environments of Central Asia, Eastern Europe and Russia. These regions feature a considerably shorter growing season and colder temperatures. Instead of waiting for the seasons to change, the subspecies developed an autoflowering gene to ensure reproduction before the temperature plummets.

Autoflower Hemp Seeds

Our autoflower strains are a great option for beginner growers or those who want their plants to flower and be ready to harvest as soon as possible. For autoflower, you often need a larger population vs. full term.

For those in warmer climates, where multiple growing seasons are possible, or for those who have shorter photoperiods, autoflower is a smart choice. Often, this line needs to be planted tighter due to the size of the plants and still trying to shade out weeds before canopy grows.

Terpene Profile: Sweet, spicy profile that’s consistent batch to batch

In The Field

Difficulty: Medium
Cycle: Early finisher

We recommend 10,000-20,000 plants per acre. When planting the autoflower varieties we recommend coated seed into direct ground with plant tape application and/or using a precision planter to skip the step of going into flats.

Designed to finish quickly, upright and uniform growth habit ideal for mechanized harvest
