well, i've only grown indoors, so i don't know what strains are going to give you the most yield in a tree, but here's a summary of my favorites qualities...
sativa seeds (nirvana) full moon (highland thai), is fucking bushy like mofo, takes it's sweet time flipping, refuses to sex in anything less than 2 gallons, hasn't had it's hermie traits bred out, and if you cut it down at the start of flowering for turning hermie, you'll mostly just get a potent stone, BUT that authentic tutti fruity (juicy fruit gum etc.) flavor is awesome and a member here that's finished it says it does live up to the trippy reputation. other breeders use meao & koh chang thais that don't have the tutti fruity flavor of real highland thai and they're the only source i know for it. if i could do an outdoors grow like you, THAT would be one of my first choices.
sweet haze, stretchy, and maybe not a 1,000 bud oak tree, but the buds are chunky and sticky with an extra fruity flavor, and it finishes in just 9 weeks. it's probably more of an indoor strain where you'd get more trippiness out of something like ace's old timer's (purple) haze. i'd like to try and grow that some day too, but for faster turnaround, sweet haze is nice.
holy smokes' malawi gold is way less fussy than highland thai and flips quickly. there's a grow report on it from down under somewhere. i don't know how it compares to ace's version, but if you buy it at attitude, you can score 2 more of it as freebies along with 2 each of mozambique (similar to durban) poison and mulanje gold. man, i'd love to see a proper shootout comparing those 3 against some others! i had to cut mine down early when it got hot spot burnt from forgetting to turn my fan on, but at the 30 day mark, the buzz was already very nice, though not too trippy yet.
high quality seeds haze x skunk. not the trippiest strain, indoors at least, maybe, but under a 400w halide, it's tops were crazy potent putting even columbian gold to shame with no stone beyong lead eye at high doses or even after a month! very motivational and med quality. i lost 10+ pounds on it in just a month by ignoring hunger pangs as well as kicked my 6 pack of red dog a night habit on it. i bet you could get nice yield out of that 12 week strain as it has a single bud every couple inches of it's stretchy side shoots. it's very resinous too. it has a less than delicious cigar wrapper taste like some hazes apparently have, but blunt lovers would get off on that, and it's nowhere near as nasty as catpiss or some other flavors.
mekong haze... supposed to be one of the trippiest strains in existence. it's cheap, but get a heating mat if you decide to try it as 2 of us couldn't get it to pop in colder rooms in winter. it has tiny beans. i'd like to try it again for breeding when i get more ambitious and grow beyond more indoor practical hybrids like jack.
gage green has columbian gold and black and a solid rep. according to him, the goldis trippier, but he likes the black better as it's smoother.
gage green, ace, holy smokes, world of seeds & cannabiogen are some of the best sources for landrace genetics. ace's golden tiger is in one member's top 2, and another REALLY loves their red haired strawberry panama.
please do share your results and compare whatever you grow with extra attention to SMOKE REPORTING puhlease! i only care about how a strain smokes.
if it was my grow, i'd go with
full moon
old timer's haze
mekong haze
columbian gold
malawi gold (+ mozambique & mulanje)
&
panama
oh yeah... if you want a crazy energetic and euphoric strain, kali mist is pretty distinctive too, but just try sitting still on it.
