absolute minimum time is 2 weeks, after that the buds are still harsh though but i usually will get rid of some after 2 week cure, a PROPER cure though is a month, 4 weeks minimal to have really really smooth smoke. as for better taste and high, yes, curing your weed will give it a much better smoke, smoother smoke and plainly a higher smoke, not neccesarily cause the weed is better from curing, personally i dont beleive by curing your thc % go up, i think that when u smoke a wet bud, u have to keep incinerating and incinerating to get any smoke, doing that kills cannabinoids (so does a regular use of a lighter) but not as badly as when u got a wet bud and your just torching it to get high, so thats why i think it gets you higher (my opinion im not an expert man) im stoned and rambling now i lost my train of thought but yes curing helps get moisture all throughout the bud so its nice a fluffy (or dense) however you like it, just so its not crumbly or so sticky you cant break it up
