yes. not really. and no! haha my flytraps grow ourdoors year round. they experience whatever the humidity is outside. and water that is only dechlorinated is bad! it not only need to be de chlorinated....but also free of minerals, salts and other contaminants. distilled water and reverse osmosis water(the kind from the filling stations at grocery stores) are the way to go!warmth, humidity, and dechlorinated water!
