Is there a simple way to add humidity to a small grow, say between 6-8 cubic feet? In the winter, the air can get insanely dry - a slow as 25%. Any simple DIY ways to add in some humidity?

How big is your grow area? May be you need a bigger humidifier, to compensate for ventilation(witch removes humid air from your grow area)

Try this: Get a small 2X2 tray and 2x1 heated mat(for germination) ,put that mat on the floor of your grow tent ,then put that tray on the top of that mat and fill with water barely covering the bottom of your tray.Water in the tray will get warmer and start evaporating creating higher humidity. You can put your grow container directly in to that tray or you can build a shelf...
I am not 100% sure if it will work,but germination tray 2'x1'x7" is getting extremely humid with in fiew min when that heating mat is on...
P.S.Heating mat:[ame=http://www.amazon.com/Growers-Supply-Company-GSHM-Seedling/dp/B002LVU4Y8/ref=sr_1_3?s=garden&ie=UTF8&qid=1296264039&sr=1-3]Amazon.com: Growers Supply Company GSHM 9-by-19-1/2-Inch Small Seedling Heat Mat: Patio, Lawn & Garden[/ame]
That one is overpriced, you can find one for $20 or so...
