Thanks for all your inputs, and glad to see a little more life back on the thread.
CBTbudz- that is actually how I dry my budds anyway (when i don't have a tent free), a big cardboard box with a small circulating fan. That way i can move it to a warmer or cooler part of the house as necessary. Luckily I asked for an aletrnative date, and the only one they had was 2 weeks later. Result!! That means that I can let my ladies go to week 9 if need be, give them a week of dryiing, and then just stick in them in a big plastic storage box with a lid, duct tape them sealed, and then stick them in the loft/attic for a few hours. Might not be ideal for them, but they shouldn't be too damp by then, and should only be a couple of hours.
Also, I have Ona Block pro, and a lemon Gel from another manufacturer, which I use from time to time when we have guests, just in case the carbon fliter isn't quite up to it. Will use those around the house to keep it smelling fresh. Disaster avoided....I hope
