Ok, my room has been up and running now for 2 1/2 hours, as a dry run. My 400hps light has been on, and so has the a/c unit set at 8/10. The room is 76f, Humidity is 24%. Just as I was worried about. The a/c unit has lowered the humidity from the grow room, and is putting this moister into the rest of my house. How low can the humidity get before it is bad for a plant? Humidity in my home is usually 30-35%. Today outside we hit a very balmy 18% humidity. Yesterday was 3%.


I also am think about how much of a waste all this water is, going down the drain from my R/O system, even though I do not pay for water where I live, I do live in a desert, and you should not be wasting water down the drain. Any suggestions on what I could use this water for. I do not have a yard, but I do have veggies growing outside. Only a small 4'x8' area. Could I let this water sit for a few days and use it to water my outside, soil plants? I need my home grown tomatoes, watermelon, and canilopes. The store water ones have no taste.

Would love some advise on low humidity, I know I can raise it with a humidifier, but I would really like to stay away from one.
