Does everyone know you can out-gas the chlorine from your tap water? Fill a bucket and let it set uncovered overnight for the chlorine to slowly give itself up to the atmosphere! I learned that as a kid with aquariums and applied it to my budgies when I started breeding them. I water the orchids with water from my dehumidifier. Humidity in my basement runs 50 to 60% even with the dehumidifier running.
