Seeds
I don't know that much about seeds and breeding, if you do, post some info for new folks. I just know what most people in this game know and will try to explain it to the novices and those doing their research in preparation for the D day landing, let's help em hit the beaches a running. They will overwhelm the foe with sheer numbers. Remember, in the USA the NRA is an astroturf organization with 2 million members and a lot of industry funding (and control), a few fanatics can do a lot. If you don't think a small group of determined people can change the world, tell me when it has been otherwise...
There are many options for those who want to start growing and who don't want, or don't have access to clones. Though that could change, it's largely up to us, if a breeder has an unstabilized high CBD strain with medicinal properties, they should be able to sell clones by mail, if not, we can make it so. Canada has many reputable and long established seed banks, just go online and have a boo.
For most growers, cannabis breaks down into two basic types, indicas and sativas, with many crosses and hybrids. Auto flowers are popular with some and can offer advantages, but you can't clone them, a great choice for outdoor use in Canada. I don't know if outdoor growing will be allowed initially, another day, another court challenge, grist for the mill of the grower's associations and garden clubs.
Most growers choose a hybrid strain, a mix of Indica and Sativa strains and there are many variations, in taste, odour and cannabinoid content. Some skunk strains have that name for a good reason, cause it smells like one died under yer back porch, show the neighbors some consideration and use a carbon filter. It depends on your purpose, to get high or treat a medical condition, or maybe a mix of the two, it's your business. Almost everybody cuts clones and uses them, once they find a strain they like or that is useful, others are always trying new things. Indica dominant strains are shorter, high yielding and potent and are favored by many, a good evening choice and great soporific for medical patients or those who would like a nice restful sleep. Sativa's generally take longer to flower are taller and less dense ( some are vine like) and have a different kind of high, more of an active thing and best suited to daytime use. Over the years breeders have done amazing things and the old days of planting seeds ya got in the bag are long gone, a new age has arrived.
Many seeds you buy are genetically stabilized and generally produce consistent results, though Gregor Mendel's laws are at play and it will be always a game of odds. Most of the seeds you get will be feminized to make sure the vast majority of the sprouts will be female, better quality female seeds produce plants with few hermaphrodites. Just as in humans, so it is true for plants, sometimes the area concerning sexuality becomes blurry, with plants we get rid of em, with humans we cherish and value them.
Most people start a few seeds, cut some clones off the veg plants and propagate them, before the mother plants are put into flower. That way they have a copy of the genetics, selection of the strain to keep and propagate again are based on the results of flowering and use. Keep what ya like and chuck the rest.
