Hey guys, thought I'd post a couple questions back on here instead of making a new thread. So I've been having an issue the last few weeks w white dust in my closet grow room. All over my fan, some gets on my plants,all over reflector, inside ducting etc.at first I concluded that it was drywall dust but now I've learned it is actually coming from my humidifier. From what I have read its like mineral buildup so I'll have to switch to distilled water I guess for the humidifier. First question is the dust harmful to my plants?my theory would be yes but idk. This weekend I plan on picking up two grow tents. Will I need a humidifier if I'm vegging in a tent? I guess I'm hoping maybe the humidity will be better... If yes then I'll have to invest in a better one. Without a humidifier the humidity gets below 30 so its def necessary right now. I've since sprayed the plants down and cleaned the area just curious to see if anyone's experienced this?
