That's bad advise. Doesn't matter now that it's gone anyways, but rain on pot plants that are that close to being done can be devastating! Heavy buds that are nearly mature(especially indicas) get 4 times as heavy when wet, and will tear the branches right off the plant. If it's going to rain for days...pull em' cause they're going to mold if they stay wet and cool for more than 1 day. Yes, it grows outside naturally, but the landrace strains that are real tight, and bad about gettin mold, grow in places that it doesn't usually rain during the flowering time......like Norcal.
