I normally use the Hygrolid but I decided to try this instead, I always store my excess mushroom in a jar, they keep better and plastic can breath still and tends to leave them soggy unless I put a ton of desiccant packs inside. This lid is nice and air tight! The silicone ring really helps! The digital display is easier than the analog and you don't need to calibrate it!



I store my mushrooms at 20-25% humidity for long term storage and they always perform like the day I harvested!
