At ILGM, we make it easy to find seeds that work in Colorado’s unique climate, backed by a germination guarantee and free U.S. shipping.
Why Grow Cannabis in Colorado?
Colorado is a dream destination for many growers. Here’s why:
- Legalized recreational cannabis since 2012.
- Up to six plants per adult (12 per household) allowed for personal cultivation.
- A long tradition of cannabis culture with one of the most active grower communities in the U.S.
Growing at altitude does present some challenges, but with the right genetics, Colorado growers consistently achieve impressive results.
What Climate Is Best for Growing Cannabis in Colorado?
Colorado’s climate is unique compared to many other states:
- High altitude: More intense sunlight, but cooler nights. Plants need to tolerate fluctuations in temperature.
- Dry air: Low humidity means less mold and mildew risk — a big advantage over humid states.
- Short growing season: Outdoor growers should look for fast-flowering feminized seeds or autoflowers to finish before the first frost.
For shorter outdoor seasons, check out our Autoflowering Seeds Collection.

Before picking seeds, consider:
- Season length: Outdoor growers should choose strains that finish quickly to beat early fall frost.
