here...
for first grow you really should just grow some bagseed, otherwise if you really want to buy a pack, I'd start off with a cheaper pack just incase you fuck things up.. which is very possible. trust me, a lot of unexpected things can go wrong. personally I'd never really want to pay more than $40 for them ever... some seedbank prices are just ridiculous. for cheap packs nirvana and kc brains are the two cheapest breeders you'll find. these aren't necessarily bad plants at all.. they can grow some amazing plants and both companies have won some awards at various cannabis festivals. the reason they're cheaper is because these are many generations later of some of these plants, so there are multiple different phenotypes of each strain that could show up, but some of those could be really nice...
pretty much anything by nirvana is fine... just read the descriptions they give you and choose what sounds good to you.
for kc brains, I've heard some bad things about some of his strains, but some seem to be nice. the 3 I'd pick from would be Leda Uno, Brain's Choice, and Brain's Damage....
stepping up a little bit in price and possibly quality look at Mandala Seeds or Tiki Seedbank...
then a little more expensive (arouind $30 a pack) but supposed to be VERY good genetics are strains by Spice Brothers.... particularly the C99 or any of his crosses that use C99.
also, I don't know much about all of those seedbanks. personally, I'd only use
