Youthmananswered grow question 2 years ago Hi! Yes it's ok but in my experience i noticed that cardbox exchange/steal a little odor with the weed, especially when it's dried, and thats the risk to have a weed with a slight scent of cardbox. For personal weed, usually i use a 100% oak bedside table, It mainteins the same rH during the year ahahaha anyway, with a fan only to exchange air (like pc fans, comment below) Is perfect :)
