the list goes on and on... my advice... get a few bagseeds from a friend and try your grow first. that way if you decide growing it is too hard/complicated then you didnt waste $40 - $100 on some seeds
bagseed. just go buy a good bag of smoke and save the seeds and practice on your first grow. do a lot of reading then buy some seeds for your second grow. its just such a bummer to spend money on seeds and not use them to their full potential
