So I put in a new (stronger) fan, overnight my plants are now starting to droop..... yesterday the room got to 82 so i sprayed some water on my plants leaves and such could this also be the culprit?
Mass air-flow across the leaves will cause the foliage to evaporate water faster than it can take it up from the roots. That means the plant can't then cool itself, so the leaves droop to reduce the amount of light hitting it's surface. It's a survival mechanism to keep the plant cool. Low humidity + 80* temps = bad
