Here I am thinking of all these ways to make a CO2 generater. When I have a monster generater right here. I live in the great white north. Like most homes here I have a gas furnace. Which produces huge amounts of CO2 every time it kicks in. A furnace not vented correctly has killed families every year. A purchased CO2 generator is just a natural gas burner. Venting CO2 out the top. What if a small 1/2" piece of PVC was attached to the larger PVC furnace venting pipe. Has anyone ever tried this,and to what result. There would be no concern of heat at all. The burning of propane or butane produces CO2 and a home furnace produces about as much as 10 or 15 commercial generators.
I was right this is possible. Here is a link to an article called "CO2 For Free". Check it out you guys.....feedback desired http://ezinearticles.com/?CO2-for-Free&id=48431
dont they also produce carbon monoxide? just a thought... u will have carbon monoxide going into your house
I don't want to be the guy on the evening news that just killed his whole family by diverting his furnace exhaust to his marijuana grow. I will stick to plain old air before doing that one.
Guys guys guys, you didn't read the link. First of, a natural gas hot water heater throw off the exact CO2 that a CO2 generator does. All a CO2 generator is is a burner attached to a PPM instead of a thermastat. A furnace puts off massive amounts but is only used in the winter. A hot water heater is used year round. Most people take their showers in the morning. If you coordinate the light turning on around these times, that is when the plants need it most. A WH puts off a fraction of what the furnace does. By using climate control and opening and closing dampers you can set it up like a generator except free. You should read this link, its awesome. I agree the furnace is a risky idea. It is CO2 its generating. This article I linked is called "CO2 for Free" please read it guys......I'mm going to do it and post pics and results. If I make my room airtight and post detectors all around it will be awesome.
Carbon Monoxide is only produced from Gasoline engine exhaust and furnaces that burn gas or Kerosine. Natural gas produces CO2. Unless you have oxidation or unburnt fuel. A co2 generator produces the same amount of danger that is produced by a water heater. As long as you don't exceed 5000ppm in the grow room and really try to keep it at 1500ppm. Things should go fine. Most dangerous furnaces are old or improperly installed. All things correct if you have a natural gas water heater then you are producing CO2 in usable amounts.
i cant believe i read that whole thing lol... but personally i dont think i would mess with anything like that, even if a hot water heater produces less... just make sure u have CO2 and carbon monoxide detectors in the grow room... and maybe add one of each in the area the hot water heater is in? Just to ensure u dont have a leak or malfuntion... better safe than sorry.
I wish I didn't have to think of something like this but my room is aweful tight. I have two CO detectors which read how much ppm in air and set to go off at 5000. Our hot water heater runs mainly the first three hours of the day which corresponds with need. Actually I think if I keep the hose diameter small, say 1/2". Its only 4' away from the room. With a little plastic around the top in the rafters ought to keep it strickly in the room. Temp is going to be an issue in June or July. There is absolutely no doubt that the CO meter is nessesary. I am going to do it and take some min max readings on the CO2 levels. We'll see.
