For those who who can't wait and need a quick method to dry your marijuana plants you should hang them upside down in a dark room and increase the temperature in the room to more than 90% Fahrenheit (about 32% Celsius). This will probably require an electric- or gas-powered heater. The room should be well ventilated, but if the buds are rather tightly packed a large amount of marijuana can be dried in less than a week. If there is no specific need to do this, then taking an extra week is worth it.
For one thing, if buds are dried close together and any mold should appear, its spread will be rapid and fatal. Also, the increased heat can cause the marijuana plants to dry unevenly depending on their orientation in the room. Finally, they might dry out too quickly and once again you'll face the problem of dry, brittle buds that don't smoke evenly or taste nearly as good as naturally grown buds should taste.
Pay attention and make the necessary adjustments. If the room is too humid increase the airflow without decreasing the temperature. Make sure that heat is reaching all parts of the plant equally and your marijuana buds should be fine. The best method however is to allow the buds to dry in a cool dark place over the course of a few weeks. Patients is a virtue in terms of well cured bud.
If you want to quick dry just a little marijuana for more immediate consumption, place then on a cookie sheet or oven tray, and bake at a temperature of between 150 and 200% Fahrenheit (about 65 to 95% Celsius) for about 10 minutes. It won't taste as good as the slow-cured bud and will likely be harsh, as all water has been aggressively removed from the plant and plant chlorophyll has not degraded, but you shouldn't sacrifice any of the bud's potency.
Watch it carefully, though; if it burns or becomes too dry you might as well add it to your organic compost heap for next year's cannabis crop because it won't be any good for smoking. This would only happen if you're careless, or if the heat is well above 200 degrees Fahrenheit.
This extreme measure is best used as a short-term remedy to test the quality of the pot, or perhaps to tide you over through a dry spell while you're waiting the week or so for the main harvest. Whichever method you choose, make sure that you monitor each bud for signs of mold and remove those immediately from the drying area. Mold can be as detrimental to your marijuana plant as any other pest, human or animal.
