I've been smoking Sensi star, durban poison, and Mendocino purple every day for years they all still get me ripped. You can get a mendo purple cross called Da Purps its good.
But to get back on point Pre98 bubba , Cataract kush , chocolope , sensi star are all strains that I have grown that are very easy to grow and have great potency!peace RedMan
if you want brute force indicas, G13 & heraoauna should be on your short list. personally, i go more for mids to high and would suggest CH9 for a compact low odor, quick flowering, potent strain that doesn't put you to sleep and that has nice happy euphoria. that's about as stoned as i care to get.
my LSD was crap (especially compared to the plants it was growing next to)...yielded ok, but potency was mediocre and smell was kinda unpleasant. Also mutated... it was just one feminized plant though...I had LSD at Barney's coffeeshop, and it was great.
