Just like the title says, what are some good indoor strains that remain short without topping and what-not, but are also highly potent and under 100 bucks for at least 10 seeds?
lowryder is a great option, or a lowryder cross because its an autoflower variation. orginal northern lights CAN be found, check the latest issue of SKUNK mag you can buy it from Ontario seeds. and bubble gum from TH is some decent stuff, really easy to grow as well if you dont have much experience. props to nongreenthumb on that one!!
Lowryder crosses : AK47 or Kush Low, fast, with a decent punch.
or
any true indica strain like Papaya by Nirvana, just $ 25 at the Attitute in bloodie old england.
