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.
