As the cannabis industry continues to grow, enthusiasts and cultivators are paying more attention to one of the most critical aspects of cannabis cultivation: the seed. At Weed Seeds Co., we believe that quality cannabis begins with premium seeds. Whether you're a seasoned grower or just starting out, understanding cannabis seeds is the first step toward growing healthy, potent plants. This guide covers everything you need to know about cannabis seeds from types and characteristics to storage, germination, and buying tips.

Cannabis seeds are the foundation of every marijuana plant. They contain the genetic material that determines the plant's characteristics, including its growth pattern, cannabinoid profile, and yield. These seeds are produced when a female cannabis plant is pollinated by a male plant.

When grown under the right conditions, cannabis seeds develop into fully flowering plants, ready for harvesting. However, not all seeds are the same the type of seed you choose has a direct impact on your growing experience and final product.

Types of Cannabis Seeds

At Weed Seeds Co., we offer several types of cannabis seeds to suit different growing styles and goals:

1. Regular Seeds

Regular cannabis seeds can grow into either male or female plants. This makes them a favorite for breeders who want to create new strains. However, growers need to identify and remove male plants early to prevent pollination.

Pros:

Ideal for breeding.
Strong, natural genetics.

Cons:

Requires early sexing.
Risk of male contamination in grow rooms.

2. Feminized Seeds

Feminized seeds are specially bred to grow only female plants, which are the ones that produce buds rich in THC or CBD. These are perfect for growers looking to maximize yield without worrying about male plants.

Pros:

Guaranteed female plants.
Better for small spaces or indoor grows.

Cons:

Not ideal for breeding purposes.

3. Autoflowering Seeds

Autoflower seeds switch from vegetative to flowering stage automatically based on age rather than light cycles. These plants are often smaller and faster-growing, making them perfect for beginners.

Pros:

Quick growth cycle (8–10 weeks).
No need to change light cycles.

Cons:

Lower yield than photoperiod plants.
Less flexibility in training techniques.

Cannabis Seed Quality – What to Look For

When choosing cannabis seeds, quality matters. Here are key signs of healthy, viable seeds:

Color: Mature cannabis seeds are dark brown or black with tiger stripes or spots. Pale or green seeds are often immature.
Hardness: Good seeds are hard to the touch. Soft seeds may not germinate.
Size and Shape: Seeds should be round and plump, not flat or misshapen.
Float Test: Drop a seed into a glass of water for 1–2 hours. Viable seeds often sink, while non-viable ones float.

At Weed Seeds Co., all our seeds undergo quality checks to ensure maximum germination success.

How to Store Cannabis Seeds

Proper storage can keep cannabis seeds viable for up to 5 years or more. Here's how to store them correctly:

Cool, Dark Environment: Store seeds in a refrigerator or dark drawer. Avoid temperature fluctuations.
Dry Conditions: Moisture can trigger germination or mold. Use airtight containers with desiccants (like silica gel).
Labeling: If storing multiple strains, label each batch with strain name and purchase date.

Germinating Cannabis Seeds

Getting your seeds to sprout is an exciting step! The most common method is the paper towel technique:

Soak the seeds in water for 12–24 hours.
Place them between two damp (not soaked) paper towels.
Keep towels in a warm, dark space (70–85°F).
Check daily. Roots usually appear within 2–7 days.
Once a taproot emerges, transfer to soil or your grow medium.

Indoor vs Outdoor Growing – Choosing the Right Seeds

Indoor Growing

Feminized and autoflowering seeds are ideal for indoor grows, especially where space and light are controlled. Choose strains with shorter flowering periods and compact structures.

Outdoor Growing

Regular or feminized photoperiod strains often perform better outdoors due to natural light cycles and space to stretch. Make sure to choose seeds suited to your local climate.

Cannabis Genetics and Strain Selection

At Weed Seeds Co., we curate high-quality strains known for strong genetics, potent effects, and reliable growth patterns. When selecting a strain, consider:

THC/CBD levels
Sativa, Indica, or Hybrid
Medical benefits or recreational effects
Flowering time
Yield size

Northern Lights (Indica, fast flowering)
Girl Scout Cookies (hybrid, high THC)
CBD Critical Mass (high CBD, medical use)
