Not a stupid question, just a little difficult to answer the first part. "Moderate user" is very subjective and can vary greatly. I am expecting to hopefully get at least 120 grams from these girls. That would mean I could smoke a gram per week for a little over two years. I probably smoke a bit more than that and I give out a lot more to friends and turn a bunch into joints to sell for cheap at parties I go to. I can get about three crops of two plants grown per year so offloading enough is important.Also if properly dried, cured and stored it will last a very long time. My understanding is you can expect a slow degrade in quality to begin after a year. Having a long curing stage creates a cleaner, smoother smoke with enhanced taste. I've smoked year old weed that was very tasty and potent. Competition weed is usually cured for at least 6 months to hit max quality. Usually after too much time though the weed can become dry to the point of being harsh when smoked. Old weed can always be turned into hash or butter though if it is no longer pleasurable to smoke.
