So, is it actually legal to buy cannabis seeds in Colorado?

Yes, it is legal to buy cannabis seeds in Colorado - with a few exceptions.

In 2012, Colorado passed Amendment 64 to legalize recreational marijuana.

Under this amendment, adults aged 21 and up can possess up to 1 ounce of cannabis flower and cultivate up to 6 plants per person, with a maximum of 12 plants per household.

In 2018, the state legislature provided further clarification on home cultivation laws. These laws explicitly allow adults 21+ to buy and own an unlimited number of cannabis seeds.

This is because seeds do not count toward the legal limit of 1 ounce/individual, 6 plants/individual, and 12 plants/household.

Therefore, anyone 21 and older can freely buy seeds and grow cannabis plants at home for personal use - as long as they follow the possession and plant count rules set by Amendment 64.  

However, individuals looking to commercially sell seeds or start a marijuana business must first obtain the required state licenses through the Marijuana Enforcement Division.

Where can you buy cannabis seeds in Colorado?

There are several options for legally purchasing cannabis seeds in Colorado. Adults who are 21 and older can buy seeds from licensed dispensaries, grow shops, or online seed banks.

Which Cannabis strains do well in Colorado?

Colorado offers superb growing conditions for cannabis with its sunny days, moderate rainfall, and rich soil. Most strains thrive in both indoor and outdoor setups across the state. However, some cultivars are particularly well-suited for Colorado's arid climate.

If you want robust harvests from your 6 permitted plants, consider growing these recommended strains:

1. Durban Poison

Durban Poison is a great strain for beginner and experienced growers. It has a delicious piney flavor and can grow over 8 feet tall. Durban Poison was originally developed in South Africa in the 1970s by the renowned grower Ed Rosenthal. He created it to thrive in cold climates. 

This is a fast flowering strain, ready for harvest in as little as 7 weeks. That allows multiple harvests per outdoor season with potential yields around 1.5 pounds per plant. Indoor yields reach 1 to 1.5 pounds per square meter with proper training.

2. White Widow

White Widow is another renowned strain prized for its large, potent buds and stellar genetics. It was first bred in the Netherlands in the 1990s by crossing a Brazilian sativa and an indoor indica hybrid. White Widow has become one of the most popular cannabis strains worldwide. 

This strain stays short, around 3 feet tall indoors. Outdoors it can reach up to 6 feet tall. White Widow flowers in 8 to 10 weeks. Careful cultivation can reduce that to just 8 weeks. Its high yield potential ranges from 1 to 1.5 pounds per plant.

3. Granddaddy Purple

Granddaddy Purple is a popular purple-hued strain bred from Big Bud and Purple Urkle in California. This robust hybrid thrives indoors or outdoors with high disease resistance. It's a great pick for new growers but also appeals to pros for being low maintenance.

Indoors, Granddaddy Purple reaches 1.5 to 3 feet tall. Outdoors it can stretch to around 6 feet. Flowering takes 8 to 11 weeks. The sweet berry and citrus flavors make the wait worthwhile. Yields range from 0.5 pounds per light indoors up to 1 pound per outdoor plant.

This West Coast strain transitions seamlessly to Colorado's dry climate. Its short height fits small spaces while its strength and flavors satisfy the pickiest palates. For new and seasoned growers alike, this strain checks all the boxes.

Girl Scout Cookies is another renowned California hybrid - a cross of Durban Poison and OG Kush. It offers easy growth, powerful 23% THC levels, and a delicious mint chocolate aroma. This mold-resistant strain stays short, not exceeding 3 feet indoors or 6 feet outdoors. 

Flowering hits peak THC at 7 to 9 weeks. SCROG or topping boosts its plentiful branches for maximized yields up to 1.5 pounds per light or plant. Its happy, relaxing high provides quality smoke perfect for sharing with friends.

5. Northern Lights

Northern Lights is a popular pure Indica strain first developed in the 1980s. It has since won numerous cannabis cups for its resinous buds and superb high. 

Northern Lights thrives indoors or outdoors with its long leaves and abundant sugar-like trichome production. It stays short and bushy, making it easy to grow even for beginners. These plants mature in just 7 to 8 weeks with THC levels around 18% on average.

When cultivated properly, Northern Lights can yield over 1.5 pounds per light indoors or 1 pound per plant outdoors. Growing techniques like SCROG or SOG can improve its yields.  

After nearly 4 decades, Northern Lights remains a staple of cannabis culture. Its relaxing, dream-like body effects please both recreational and medical users. This stable, high-performing strain is an ideal choice within Colorado's legal home grow limits.
