I wouldnt put air fresheners in the same box as the Herb, otherwise youll have bad tasting Herb after just a few hours. Get a mason jar, they only cost between 3 and 5 quid depending on the size. Theyre airtight, but you will need to open it for 15-20 minutes per day to prevent molding. Youll also be curing the bud at the same time as well. Make sure that the bud isnt too tightly packed - pack the mason jar about 2/3rds full. If the bud is dry, whack a SMALL piece of orange/banana/apple etc peel in there. Your bud will get a little moister, and will also have a slight hint of [insert chosen fruit peel here] smell and taste. Be sure that the peel doesnt touch the bud though, and check on the bud every 6 hours until its as moist as you want
