I've never had any Mexi-crap that even came close to resembling a Sativa.
unless you're talking about the quality of the stomped on brick bud you smoked, you're very wrong! i used to have a collection of a bunch of different sourced mexican bagseeds i WISH i still had. even in brick form, some of it wasn't that shabby. i had two beans i named "spicy" that came from BRICK that had the same peppery flavor as original kali mist, but with actual psychoactivity. i wish i still had those! i named other strains for the color coded $5 & $10 sacks i stored them in... purple (haze), (columbian) gold and i had a bunch of (panama) reds that stretched to over 6 feet tall in a closet under a single shop light the room mate i gave them to used in under a month. those babes had razor thin leaves and i bet would have been even better than the way better than afghanicrap street beasyters that were the only other game in town where i scored them. mexcom is awesome! i wish i had a bunch of it right now.
when you get into REAL sativas, you get into the even funner than motivational aspects, and get into the psychoactivity that at low levels, just makes everything funner and more significant eg. movies feel more real and junk food is orgasmic, to flat out having visuals that rival a low dose of LSD like the crappy one i had that took 7 hits i'm positive were soaked first. columbian gold would really warp reality if you didn't overdo it and get that annoying room spinning dizzy effect.
C99 and a lot of generic hazes have a nice happy motivational buzz that leans more towards clear headedness, though even generic hazes have a bit more psychoactivity in them, but low amounts compared to "legit sativas" like columbian gold etc. it's a good fast finishing strain if you want something for activities without tripping out. it's a good wake & bake work weed strain. it's not as good for chilling out.
DNA's sweet haze is fruitier and trippier than many generic hazes and thais that don't live up to the rep of the real deals. it's stretchy, but finishes in 9 weeks. it's very high quality all arounf for a 9 week strain.
high quality seed's haze x skunk is stretchy and takes 12 weeks, but has a cool "single bud every couple inches" branching pattern that might compensate a lot for the wait in a SCROG. it's REALLY potent and motivational with at least a little trippiness. the cheesy cigar wrapper taste from the skunk isn't a favorite, but it's bearable and totally makes up for it in the buzz that's very long lasting, and even after a month of waking and baking, is still no more stony than some lead eye where columbian gold could turn into stoner bud and force you to purge a couple weeks to get your tolerance back down. haze skunk buds are much more resinous. it's a little unrefined, compared to sweet haze, but it has tons of potency to compensate and might yield more because it makes so many more buds. i was able to quit a 6 pack a night addiction on it as well as start losing weight just by keeping busy and happy on that gift from god.
TGA Subcool jack's cleaner 2 is my current favorite strain. it's stonier than the others, but might be more visual. i laughed my ass off when i noticed i was imagining invisible tie dye ripples of color emanating from where i was rubing my arms. why was i touching my arms? it has a really cool and sensual touchy feely effect that's a lot of fun along with a cool "warm blanket" effect in it's complex stone. it's not as light and floaty as columbian is, but touchy feely is fun too.
jack herer is the shit though. it's the haziest indoor strain you can do indoors. even in watered down hybrids, it's no worse than even more watered down alleged hazes. sannies $50 jack f7 is the most "legit" herer you can get at that price though their own killing fields and TGA Subcool's jack the ripper hybrid are probably trippier.
if you really want to get into trippy strains, expect stretchier varieties and 12 week plus waits. i can't wait to sample my holy smokes malawi gold, especially after hearing just how trippy their mulanje gold is in a thread by an aussia malawi grower. delta 9's cambodian based "mekong haze" (not an actual haze) is supposedly one of the trippiest pure sativa strains around, but you might need a heating mat & humidity dome to coax it out of it's shell as i and another grower couldn't get the $20 5 packs to pop.
if you want to get into landrace sativas for the purest highs, ace seeds, gage green, holy smokes & world of seeds are 4 of the breeders preserving more landraces than others. one grower here loves his ace panama and another swears by their golden tiger as well as mandala's satori. i really liked mandala's 8 miles high myself. it's trippier than a generic haze with a perfectly neutral energy profil with plenty of playful euphoria that just wants to have fun and with a precise body control effect that the closest to the light & floaty one i used to get off columbian.
if you want to get an actual "haze", neville's is the "original" that a lot of breeders have probably used and famous for being trippy, but if you know where to find it, JYD haze is supposed to be really trippy. the auther of cannabible liked dr atomic's metal haze too, but most of the dealers that sell it are sketchy, but i've had great dealings with hemp depot so far.
there's a lot of great strains out there you can get high off, but information isn't easy to come by. hopefully these suggestions prove a helpful start for you. i'm still looking for better, or at least unique highs still. i hope malawi gold proves as trippy as columbian, but can't wait to try jack f7 myself and want to try third dimension too. down the road, i want to re-try delicious tutti fruity highland thai based full moon, but that one is a hermie prone bitch to grow, give mekong haze a 2nd try now that i have a heating mat, and especially try ace's oldtimer's (purple) haze to try and make a trippy purple & grape strain. that one is a 17-24 week pain to work with, but when it comes to getting high, good things come to those that wait.
DNA's lemon skunk is a nice "light high" that isn't trippy, but nice and euphoric with more motivation than skunk #1 and a better lemongrass flavor. i was surprised that i liked it as skunk #1 is only a little better than typical street crap to me. one of the things that makes it special is it's golden pistils give the plant a really cool golden glow that suits the lemony flavor. it doesn't overdo anything, but it's a nice classy well rounded package between mids and generic hazes.
