This has led to an explosion of interest in the best Canadian seed banks. To some extent, of course, there is a bit of subjectivity in what makes a seed bank great. But overall, it’s not that hard to see the difference between the many online seed banks that ship to Canada.

Our favorite mix: the Summer Feminized Cannabis Seeds Mix Pack. This one has 8 seeds total, 2 of each variety: Blueberry for that classic, easy indica grow; Northern Lights for a deep body stone and piney finish; Cinderella 99 (C-99), which is one of the best hybrid strains going, still; and a cross between Bruce Banner and Gorilla Glue GG4 for another knockout hybrid.

Also, in case it is important to you, do not assume because they are listed here that their products are Canadian-grown. Check with the sources to get your questions answered.

While I would like to list everything these individuals and companies sell, it is nearly impossible to keep on top of the changes, so please go directly to their sites for info.

While this started primarily as a seed company directory, there are also sources listed that sell plants and bulbs.
