Fuck even trying to cure in any containers to start with,if your drying/ curing lbs then turkey bags is the way to go,ya get over an lb per bag & they are food grade.
I cut 4 to 5 lbs per week on average & all cured in xxx large turkey bags,most dollar stores sell em & they work great.
I also cure in 5 gallon plastic buckets using a gasketed lid when i have large harvests from the outdoor stuff in late fall,whats important is taking away enough air to effect a sweat within the buds,air tight is not mandatory it just gets the sweating going faster,ive also used contractor garbage bags to cure,a little slower than buckets or bags but work none the less.
The short time span the buds are cured for dispensing wont impart any taste unless you use a filthy recepticle,the time the buds are exposed to the air is sufficient to make sure no outside tastes settle within the bud,durring cure the buds are putting out more odor & chlorophyll than most containers are off gassing ,this makes it very hard for smells & tastes to settle in the bud,its only after the buds have expelled most their chlorophyll that smells will begin to impart taste on the product.
