I have not found any weed to be productive for any learning/studying in any of the sciences /shrug
Making art, music, or generally being creative sure. As far as applied sciences it is a no go heh. Your memory and focus while under the influence is not 100% and that is what you need for that realm.
(Western-winds) Sagarmatha....very creative and focused
(Strawberry-Blue) World of seeds........very up high and great tasting
Just to name a few many many more....like above stated mostly sativa is what your hunting....Good luck in your search........ST
I would suggest a good land race / sativa hybrid. As one Q said panama would be good, i have made a Swazi /Skunk #1 cross for this very purpose. The swazi on it's own is a nice mellow up high, and the skunk gives it that punch to really get you "into the zone".. So something along those lines would do you right.
Something i would suggest though is not going to close to the 100% sativa's, such as a haze or a near haze hybrid, the high is too electric and you are not going to be able to sit still and read anything for shit. Just my 2c, good luck with the search
