This kit is needed when you purchaseone of our Hemp Flowers. We wanted to include two choices to this kit: One (1) 58% 8g Boveda Humidity Pack and One (1) 62% 8g Boveda Humidity Pack! Many folks recommend either for keeping your Flower properly humidified so it doesn’t become dried out and dusty. We made this kit so you can decide which you prefer to keep your Flower fresh!
