I still say start good genetics right off the bat just something easy to grow.
my first ever grow i really didnt mess up bad at all.. I got her to harvest and got 2 oz dry of amazing smoke.
alot of Nirvana's strains are great and easy to grow. I've personally grown their bubbleicious,jock horror,ice and northern lights.
norther lights or skunk #1 are the 2 strains I would tell anyone to start with.
world of seeds (breeder) - afghan kush or even their afghan kush ryder are both easy to grow.. so is their northern lights x big bud
