Need to travel, how to dry to prevent mold ? First harvest please help.

Hi. I ve harvested some plants 2-3 days ago. The little leaves have been trimmed and the weed has been drying in the dark for a couple of days but is still not in the stem snapping level. I need to leave the country in 1 day and it must be stored with other household items in a warehouse. I pressume it will have low. normal humidity since it will be high temp weather. But how can i do a final dry to prevent everything from getting mold ? Its about 300 grams of pretty good weed, and its my first ever harvest.
