703 results about "Ambient humidity" patented technology

Ambient humidity is what’s happening outside your container of cannabis. It could be your bedroom, the trunk of your car, or the outdoors. In air conditioned homes, the humidity is usually 20-30% because the AC scrubs moisture out of the air. In a heated home, the humidity will often be even lower as the furnace scrubs much of the ambient humidity.
