for a tent a humidifier is small is likely superior due to logistics. I recommend a fogger for open rooms though. Mine was $100 US, and the power supply has two extra rails so I can wire in other gadgets, like PC fans and such. The original use for a fogger is for a tent sized humidity chamber for cuttings/grafts/cloning. I will be experimenting with it for growing mushrooms too. I may set up a mini tent in the grow room for it, and the extra fog will be blown back to the room with a PC fan tent exhaust.
