Are you unsure what the labels above mean and how to use them to choose? Our website features various classifications to help narrow down your option pool.

Autoflower and feminized cannabis seeds

Cultivators used to be limited to regular pot seeds. This variant develops into an assortment of males and females, letting you produce buds, pollinate and replenish your batch, or create novel hybrids. The versatility is impressive but not optimal if you only want to grow usable buds. Males carry pollen, so you would discard half your plants after the vegetative stage with regs.

 

Breeders solved this issue, and feminized seeds soon took the spotlight. You can now buy cannabis seeds and watch each one become a bud-bearing female. This variant contains no male chromosomes. You face a lower risk of accidental pollination and collect sticky, seedless, smokable flowers from every plant. Get this version if you grow to produce buds only and have the time and weather for a more extended seed-to-harvest period.

 

Crops from female weed seeds are photoperiodic, and their growing season lasts 3–6 months. What if you could get buds even sooner?

 

The answer lies in autoflower seeds, which add a twist to your usual indica or sativa strains. They combine popular cultivars with the third marijuana family: ruderalis. Ruderalis strains developed in Eastern Europe under harsh weather. They evolved to flower automatically after 5–6 weeks of vegging, finishing their life cycle in less than three months. These plants aren’t psychoactive enough for toking but are gold mines of beneficial genes.

 

Crops from auto weed plant seeds retain their smokable parent’s flavor and effect profiles but display non-photoperiod traits. They’re smaller and lower-yielding than their photoperiod counterparts, but they let you harvest twice in a single season. Most autos are also all-female.

 

Get autos if you already have some marijuana gardening experience. They’re perfect for small grow rooms and outdoor areas with short summers.

Indica, sativa, and hybrid weed seeds at I49 Genetics

 

Cannabis seeds that produce potent buds come from two families: indica and sativa. Most of today’s strains originated from landraces, naturally-occurring plants from remote regions.

 

Indica came from the Middle East, particularly Tibet, Afghanistan, and Pakistan. Since these areas have harsh climates, plants are short, bushy, resistant, and fast-flowering. They contain high CBD and THC levels and predominantly physical and relaxing effects.

 

Sativa is indigenous to East Asian regions, South America, and South Africa. It developed in areas with a tropical climate, making it grow tall and skinny and taking its time to ripen. Crops are rich in THC, delivering energizing, uplifting, and psychoactive effects.

 

Marijuana from sativa seeds doubles as a wake ‘n bake and pick-me-up, while buds from indica seeds serve as a nighttime toke. The selection of weed seeds in the USA is broader than these two categories.

 

Once landraces arrived in the States, breeders started combining their traits. That’s how we got hybrid weed seeds. Most cannabis seeds in the USA are hybrids exhibiting various indica and sativa features. You can find specimens bred to grow big yields, produce plenty of THC, or suit a medicinal purpose. Some are indica or sativa-dominant, and rare ones display a 50/50 split of both genes.

Indoor vs. outdoor cannabis seeds

When you buy cannabis seeds online, you can choose every aspect of your cultivating and smoking experience. One critical decision is whether you’ll grow indoors or out.

 

This categorization isn’t as strict as indica, sativa, photoperiod, or auto. Nothing about the genetic material classifies seeds as indoor or outdoor. You can sow in either setup, but some have preferences, and you see better results when you respect them.

 

Outdoor cannabis seeds thrive under natural conditions. They don’t mind climate fluctuations and enjoy a soil-based medium and sunlight exposure. These cultivars require warmth, but you won’t see a ruined harvest after a week of lousy weather. Get these weed seeds if you live in a balmy state and have a free plot of land. Sow in the great outdoors and let nature ripen your buds to perfection.

 

All strains began outdoors, but things changed. Now, breeders create hybrids under specific conditions, and they only thrive in that particular indoor environment. You might buy weed seeds that never see the light of day.

 

Indoor cannabis seeds enjoy the stability of grow rooms. They flourish under lamps and love the steady climate and humidity kept in check by devices and your watchful eye. They like training techniques and remain small enough for restricted spaces. Choose from this category if you don’t have available land or amenable weather. Optimize the environment and see hefty harvests for your effort.
