There is a large variety of sources for seeds. For the most part all of these companies sell the same varieties of seeds. If you want to go the normal route of plants that follow the photoperiod (18/6 veg, 12/12 flower) there are feminized seeds (all female) then regular seeds (can get males and females 50:50), or you can rock out on autos (24/0/20/4). Never grown an auto but I do have the internet so for the most part I must of by now. have some free autos I'll pop soon, I'd say I'll report back but I know I'll forget this.. It took me close to five mins to write this because the weekends are for day drinking!
