mandala's gear is both cheap, and some of the most noob friendly there is. i didn't give his hashberry a chance though as it gets really funky, but loved his out of circulation until next year 8 miles high. it's a very fun high that's better than generic hazes.
northern lights #5 is a really good beginner strain. it's low odor and one of the original cash cropper strains. it's in tons of crosses.
if you want a crazy fun high, TGA's jack's cleaner 2 is my favorite so far. it's a 9 week strain with a stony edge, but has real psychoactivity which most strains, even a lot of alleged hazes don't have, and even more special has a really fun touchy feely effect that would be perfect for warming dates up. i prefer quality over quantity myself, but the flowering time is good for that strain and i think the yield is at least decent without looking it up.
if you want a fun flavor strain that has a little bit of funk, but nowhere near roadkill level, DNA's sour cream is freakin' delicious! it's a little too stony for my tastes, but manageable. their lemon skunk is even better though in the high department. i think that's a 9 week strain too, but the high is better than skunk #1 and it isn't skunky despite it's name. it has a cool "golden glow" about it that matches the lemongrass flavor too.
if you want something really euphoric, but stony, TGA's jillybean gets rave reviews.
yield is kind of complicated. 400 grams per square meter used to be considered a pretty good yield for cash cropper strains that finish in the 7-8 week range, but if you look into some longer flowering strains that take up to 10 weeks or maybe even more, some of them allegedly yield up to 750 grams which is probably pretty close to what you'd get from faster strains in the same space over the period of a year or more, but the better buzzes are in those strains.
too many people get so obsessed about yield and potency that they sacrifice THC profiles and flavor in the process. a few extra grams of a crappy strain is just a few extra grams of crap. what's the point? LOL
i think you'll find that strains you grow that get you high instead of stoned are going to be much more in demand unless maybe you live in socal where they're common. in many places, people are starved to get high big time and try and get their dealers to give it to them, but they only care about a quick buck and not so much growing the best possible. there ARE strains out there with real highs that yield decently and even finish quickly too these days.
