@Cannibal1988 I have had great result using seedsman seeds and they do send to Canada I checked for you
They use a good stealth method of hiding the seeds but for total stealth they will usually need to remove the original breeder packaging.
They have a vast range of both their own strains and all of the popular breeders you see on here they have them
They also give freebies ๐๐ As for strains The strongest smoke I have had came from a sativa that took 16 weeks to finish flowering I am not sure if that is suitable for your setup. So I will recommend one of the strongest indica dominant hybrids Gorilla Glue #4 if you can get the real deal it will blow your socks off buddy
