    If you'er trying to raise the RH of the room, you;ll need to buy a kenmore humidifier, but if you're trying to reduct the RH in the room, get a kenmore Dehumidifier for sure.

    In a 3-4 month dirt grow any heavy metals (which are loaded in your nutes maybe too?) will be negligible. however in a hydroponic system re using substrate and reservoirs a sink is created where the heavy metals will build up over time, and that will make your penis disengage. dont do it.

    Whoa 2010 thread and still so interesting. I laughed while reading this thinking man I hope these guys aren't growing the original lowryders under candle power. Things have changed a lot since the cell phone was created and these threads are now available to everyone besides cavemen.

    Is anyone using dehumidifier water for their plants? I also wonder if the guy from Texas is still alive for drinking from copper pipes

    Idc if peeps flame me for it: I've been using dehumidifier water for my plants for over a year now & it's fine. I also collect rain, use RO water from Walmart when I have to, and use my own RO filter when needed but it's wasteful. It is true you can get bacteria in your gray water but if you keep the sump clean it won't hurt your plants. I grow in organic recycled soil & my plants are super healthy. Dehumidifier water is fine as long as you keep your unit clean.

    I'm gonna start using mine to fill my resivour. I read something once about an apocalypse solar powered dehumidifier that says u can drink it's water and its completely safe. Maybe along the same lines

    I just clean my collection dump with hot water & bleach then wipe it out with a paper towel. Not sure I'd drink it but I do use it to fill my bong sometimes lol just realized this thread is old AF.
    If you have a hydro setup I would just use tap water; no need to bother with dechlorinated water unless you are growing in organic soil. Tap water is likely better for hydro. Any bacteria is very bad for your res but in a live soil it is consumed....

    Old af is correct. I stumbled across it during a Google search

    Funny how you can put a plant in the ground. Water it from a 100' well, ur drunken buddies piss budweiser on it at 2am, sulfur rain probably hits it, who knows what the cat dropped on it.
    But I can't use the dribbled water from my 70 pint Fridgidare dehumidifier. Lol who knew.

    I have done extensive research on dehumidifier water. It has roughly the same tds and ph of slightly yellow toilet water from a McDonald's off the side of a busy highway. A 2am piss or a large cat droppings is much more likely to produce quality h2o

    The truth about reclaim water is that it's just that- reclaimed, condensed from the air in your growroom. I've been using it for years, no problems. My tap water is very clean, about EC .052. That's not a typo. Yet the reclaim water is still cleaner. If you're worried about stuff growing in it, just use it up every day.

    There's a fair amount of misinformation in this thread.

    Condensate water can be used on your plants. But you need to treat it with H2O2, hypochlorus acid, or sodium hypochlorite.

    Condensate water sits around and it breeds bacteria, particularly Legionella. Ask any HVAC professional about why you should not drink condensate water.

    Once treated, you can use it without worry.

    Condensate water does not contain harmful levels of lead, copper, or any other heavy metal. Seriously, I implore all of you to send off your condensate water to a lab to test it. You will find that it has undetectable levels of just about everything. Heavy metal concentrations will either be undetectable or in concentrations far lower than in your tap water.

    I'm not suggesting anyone drink it, but none of those listed bacteria will adversely affect one's grow, whether in soil, soilless or DWC.

    Most houses have pipes that are soldered with lead based solder. Only a very small amount of lead leaches into the water, well below the maximum allowed amount for drinking water.

    I've been using my dehuey water for years, I usually get about 2.5 gallons a day from it, and use about 25 gallons of water every other day. At 10% I wasn't concerned with what the 8ppm in it was. Reading this I ganked a heavy metals test from work and it's perfectly clean. As for the bacteria, I've never had issues with it for the last few years, but I also pump it straight into my res.

    Nice to hear somebody who's actually tested it say that.

    My tents in my bsm, and I exhaust it right into the basement so it gets humid in there. I run a dehuey set to 65 and get about a gallon a day, I use it all the time lol.

    All these people talking like copper pipes are bad.. I live in a century old house and the actual water pipe coming into my house is a lead pipe. Some of the plumbing inside has been replaced with copper but not all.

    Like a small amount of lead solder on the copper would leach out dangerous amounts, it's not even on the inside its soldered on the exterior. Not to mention thousands of gallons of water flow past those joints in the pipes over the years, how much could really leach out?

    i run a 3 gallon dehu for my whole house, humid area, and there's usually a light bio-slime in the tank. i put a few drops of bleach in it from time to time to knock it down, but thats the only problem i could see, it might get into your res and multiply.

    aluminum is toxic to plants. most dehumidifier coils are copper covered in aluminum. Not great.
