Iamin the exact same situation as you are~!!! Man oh Man~!! I have 2-3 more weeks to go on some of my plants and YESA the buds are FINALLY starting to swell. I am looking at low 30's on Saturday and Sunday. I would normally cover but now I am reading it could get into the 20"s whcih would freeze the plants. If that happens I don't know what I will end up with...possibly mush....I have come too far to allow this to happen. I have a full moon tonight. I am in Maine. I am thinking that I will just have to harvest early and hope for the best.....But I hear you on how it sucks especially when you are seeing bud swellage.
Maybe we should both Pray together. Do you have pic's???

I did notice today that I can harvest 2 of my plants...I have one big one that has all purple buds it is beautiful. I hate to harvest it early but it is better then losing it all in the end then I would feel like killing myself ( LOL )
