Firstly, let’s make it crystal clear, keeping hemp flowers in bags is not a good idea, and you seriously consider investing in some good quality mason jars or pickling jars. Basically, sealed glass containers are the way to go, as glass cures the hemp flower and stops it from degrading over time.
Then there’s temperature and light exposure to consider, as hemp buds don’t love extremes and far prefer milder storage conditions. Ideally, you want to be aiming for around 77° and 86° F, in order to avoid mildew and mold. Then there’s the humidity factor to consider, as you don’t want to store your hemp buds somewhere too moist, or too dry. For this recommended ranges are around 59% and 63% RH (relative humidity) for maximum potency.
You also want to keep your hemp flowers out of direct sunlight which has UV rays that can degrade the buds over time. A Study from back in the 1970s found that light was in fact the biggest factor in cannabis storage, due to the degradation of cannabinoids. Exactly the same happens with hemp flowers, being rich with cannabinoids. the study also concluded that most cannabis, if stored correctly, has roughly a two-year shelf life.
The bottom line is, if you want to store your cannabis or your hemp flowers in the best way, it’s inside sealed, air-tight glass jars, about 3/4 full, and never overpacked. Store in a cool dry place away from direct sunlight. Don’t store in the fridge or freezer as a general rule of thumb, as there are inherent issues in that method. While refrigeration can make buds overly moist, freezing poses the threat of freezer burn, and delicate trichomes often degrade and fall of due to being brittle and hard.
