Ah everyone bashes the seeds or genetics, easy to say but it is a big topic open to a lot of debate, few things to go for are indica strains as they are a lot shorter than sativa strains and produce denser fatter buds, pretty much a must for most indoor grows. My feminised white widow is 75indica and 25sativa, a medium skill level grow, not easy and not hard.
There are tons of seed sites and shops, i live in europe and use Dutch Passion although i only ever bough 10 seeds of them as i made my own for years from these 10 seeds. These guys are basically your industry leaders, there at the start and they will be there at the end, prices are high but you get what you pay for, perfection and quality genetics, a good buy is white widow as a standard.
Always Dutch Passion has been at the top in my eyes and no one really disputes this, the American seed market seems to be more wide open and a lot more choice than Europe but the reputable long standing European/Dutch seed banks seem to be the best choice. As always people will have their favourites but i would say Dutch Passion is the best. I was lucky to get their white widow strain from a few years ago when it was the best seed going on the market, couple years later cheese and blueberry became quite popular but at the time the white widow from Dutch Passion was legendary and i am so lucky to have save those genetics for all my grows.
Funny enough after a lot of breeding i am getting a few plants now and again with three branches to every node, i have 2 in the grow room now like this, maybe it is breeding depression and i need some new genetics in the breeding or maybe i am lucky enough to have some very very good genetics and very desirable hard to find traits. I have yet to work this out!lol!
You get what you pay for with seeds, chep ones are hit and miss but good ones from reputable breeders are exspensive. Peace
