The 10 Best Cannabis Strains to Grow in Colorado

Colorado offers a unique niche for growing indica Cannabis. The high elevation and Rocky Mountains provide a mild and dry climate that resembles the harsh environment indicas adapted to in the Hindu Kush mountains.

Moreover, the Colorado weather, with temperatures that range from 22°C (72°F) to 30°C (86°C), does not pose a challenge to indicas that thrive in cooler climates. However, it does bring an issue if you try to grow sativa plants since they prefer warmer climates.

If you want to grow the best Cannabis strains in Colorado, cultivating indicas and indica-dominant hybrid strains is your best choice.

What type of climate is Colorado?

Colorado has a dry climate thanks to the Rocky Mountains that run through it, which prevent storms and clouds by blocking them. It also has the added benefit of giving Colorado its clear, sunny skies.

Does Colorado have 4 seasons?

While Colorado is known for its cool temperatures and scenic winters, it does experience all four seasons.

What kind of marijuana is best to grow outdoors in Colorado?

Indica or indica-dominant strains mainly because indicas are more suited for Colorado’s mild and dry climate. If you insist on growing sativas, you’ll need to grow your plants indoors.

Afghan

When choosing a strain to grow in Colorado, Afghan comes to mind. Not only is it a pure indica strain, but it’s also a cultivar that can be traced to the valleys of the Hindu Kush mountain range. That means it’s familiar with Colorado’s mild and dry climate. If anything, Afghan marijuana plants would thrive in such conditions since it resembles home all too well.

A notable trait of Afghan is its highly resinous buds that are loved by all Cannabis growers. They have a THC content of up to 20% and deliver a heavy-bodied high that makes you feel relaxed and euphoric. But there’s more. That high-resin content resulted from Afghan plants adapting by producing more trichomes to combat the cold weather and higher UV exposure due to higher elevation.
