blackseed's masterkush are OK and cheap. they're really fast flowering and compact with a buzz no more stony than skunk #1, but way faster and shorter. like other autoflowering strains though, you probably can't clone this as mine all flipped themselves quickly under 24h, but if you bred for seeds, you could fill up a sea of green quick with that strain. i'm keeping my red pheno for future breeding of compact & quick strains. i like to get high more, but i've had a lot stonier buzzes than that kush, so i at least was able to enjoy the buzz.
instead of a kush, if you want a foolproof med use strain, try northern lights #5. it's low odor, potent, high yielding, and easy to grow. it's a building block in tons of top strains. NL5 never goes out of style. flavor fads come and go, but NL5 gets the job done. i think breeders are doing NL5 autos too by now.
if you want something more skunky, mandala's hashberry is cheap and a popular cash cropper strain and his gear is very hearty and noob friendly. i didn't like that strain because it stunk a lot, but those who are after that love it in the reviews i've read.
