Dry flower refers to Marijuana that has been cured and dried. The most popular way to trim the plant for drying is to cut off the top 12 to 16 inches of the plant – including the actual flower, removing any unwanted leaves and hanging the branches that were cut off from a wire. After being picked, marijuana plants are dried and cured by hanging the plants upside down allowing all the tetrahydrocannabinol (THC) to flow down into the buds. Harvested marijuana must be placed in a dark room in a temperature range of 60 to 70 degrees Fahrenheit along with the humidity level in between 45% to 55% with a small fan to gently circulate the air. This method of drying helps prevent the cannabis plants from developing mold.
However, it does not determine whether the buds will turn out to be dry or sticky. Sticky cannabis buds have had a better reputation than dry cannabis buds as the dry cannabis buds are thought to be old or cheap versions of higher quality sticky buds. However, this is not always correct as dry weed buds simply mean that the cannabis plants may have been cured a bit too long or that they have a lower trichome count, the small hairs that make the buds sticky.

These are also the best suitable buds to be used in making edibles.
If looking for quality, then the sticky buds are the best option.
