Na your still cool,ive been there before,as long as the mold is not deep inside the bud & its mainly on the outer bud you can put it in check pretty quick.
Take that shit out of that box its in,the stale non moving air in the box is what allowed them to mold,lay them out on a clean sheet,get a quart sized mist spray bottle & fill it with warm water,then mix in about 6 to 10 spoons full of regular 3% hydrogen peroxide from rite aid & lightly mist all sides of the buds,then put a fan blowing directly on them & turn the fan up as high as it can go,turn the buds over every few hours,you will not taste peroxide when you smoke it up either because the amount is so small.
Let them dry on the sheet for 24 hours then you can put them back in a clean cardboard box or tupperware container with no cover on the container,keep a fan blowing strongly directly on the buds until they are very crispy & fluff the buds around as many times as possible to get fresh air everywhere,when you squeeze the crispy buds & you only feel a very slight amount of moisture in the inner bud,then seal the buds up in a large freezer bag & do not push the air out.
At this point your main insterst/concern is saving the buds, forget about having the buds in darkness & keep them in the light,mold breeds faster in damp dark places over bright windy enviroments.
The sealed bag will draw out any moisture in the inner bud & give an even slightly moist feeling to the entire bud,once that happens lay them out on the sheet again & put the fan back on them until they crisp up again,then reseal in the freezer bag & open the bag a few times a day to let fresh air in,when the buds are 100% dried bag them up air tight & store all excess buds that you are not smoking in the freezer,this does work & i have saved several lbs this way.
Just so you know the most effictive mold killer or preventer is plain ole fresh moving air,mold spores have an extremely hard time surviving in a moving air stream & it will die a quick death.
Next time you dry a harvest never hang or lay buds in a stale non moving air enviroment as non moving air drastically increases the risk of mold.
