Hey SS, I plan on getting a propane burner from DH in the future,,, but would like to know more info on these extra gasses. Could you enlighten me? From what I read a complete burn with propane produces nothing but co2 and h2o... How perfect/complete of a burn these burners get is the question but I would think they have engineered them properly considering they are used for co2 production exclusively in indoor grow rooms and green houses, but Im not sure about most other peoples business practices these days especially in the grow industry.

I dont think they would be ideal for heating a room because thats not what they are designed for, and maybe a propane heater would either have the ppm too high trying to maintain temps in a cold GH, or the propane heaters dont have as complete burns as the co2 generators.
Either way it would be burning mostly at night anyways and you dont even need the co2 then.
Yea i was thinking of this myself.But i thought to myself..self..cause i often to that when talking to myself.
He needs heat.Electric is normally more expensive than gas heat.CO2 is great for the plants .It would be cost effective to at least heat some with NG or LP generator.
Elevated co2 levels at night are not going to hurt the plant.they are just not going to be breathing it.In a natural type green house setting infiltration air should be all over the place for a rather constant fresh air change over and no need to vent.
Fossil fuels are a funny thing.The more efficient they are burned the more dangerous they get.
Carbon monoxide and carbon dioxide. mainly.
One of these will kill you..the other is harmless unless it gets at really really high elevated levels.
People would be dropping dead from using their ovens all over the place but the main by product of a open flame is carbon dioxide
More efficient use of fossil fuels such as in a car engine OR the secondary heat exchanger in a 90% gas furnace produce carbon monoxide that will kill you.
There is a stage and process when the carbon dioxide changes state during the combustion process to a carbon monoxide through oxidation.
CO2=carbonic acid gas;carbonic anhydride,mol weight 44.01
CO=carbon monoxide.I can tell you how to make it also but who wants to make this stuff? It is deadly shit.

Just recently switched from all T5's to a 600. I got great results with them, just wasn't getting quite the bud density I was wanting.
I may still use them for veg, but definitely gonna stick with the 600 for flower.
Here's a cpl pics from my last run.

That's 4 plants in a 2 x4 flood n drain. I've got room for 4 trays in tent . I'm waiting on some cuttings to be ready to fill it up.
Once I fill tent, I'm gonna throw in another 600 and have them on a light mover.
The strain in pic is Mandalay. I've got BB xxl, and Early skunk cuttings for next run. I've run them both before, really nice results. The skunk is a 7 wk finisher which is always a plus. lol

Problems With Using Unvented Greenhouse Heaters

A frequently asked question (FAQ) is “Can I use unvented heaters in the greenhouse, either for back-up or as a primary heat source?An unvented heater is one that is designed without a flue connection so that the heat and products of combustion are exhausted into the greenhouse. Dumping these flue gases into the greenhouse may improve the overall efficiency rating as compared to a conventional heater but the pollutants and added moisture from combustion may put your plants in jeopardy.Unvented heaters can be fired with natural gas, propane or kerosene. These fuels are advertised as clean-burning. This is generally true if the burner is clean and has been adjusted to top efficiency. A heater that has been serviced in the fall will probably not be at peak efficiency as spring approaches. Inefficient combustion can emit unwanted and harmful pollutants into the greenhouse that can affect the plants and the people working with them. Let's look a little further at the fuels and the combustion process.Natural gas (*NG) consists of more than 85% methane with varying amounts of ethane, propane, butane and inert gases such as nitrogen, carbon dioxide and helium. It has a heat value of from about 950 – 1050 Btu/cu ft. The flue gases usually contain nitrogen dioxide, carbon dioxide, carbon monoxide, volatile organic compounds and particulate mater.Liquefied Petroleum Gas*(LP-gas) is obtained from gas wells or as a refinery by-product and consists primarily of propane with traces of proplyene, butane and butylenes. It is handled as a liquid and contains from 90,000 – 98,000 Btu/gal. Propane has much of the same pollutants as natural gas.1-K kerosene*is a low-sulfur petroleum product whose composition varies widely depending on what part of the world it comes from. Its heat value is about 135,000 Btu/gal. The major pollutants that result from burning kerosene are nitrogen dioxide, carbon monoxide, carbon dioxide, sulfur dioxide and formaldehyde.All the fuels contain small quantities of many impurities that can directly or indirectly cause pollution injury when exhausted into a greenhouse. The type and quantity of impurities depends on where the fuel originated from.The combustion process for both natural gas and LP gas are very similar. Here is the formula for burning natural gas.1 cu ft NG + 10 cu ft Air + Flame gives 8 cu ft Nitrogen + 1 cu ft Carbon dioxide + 2 cu ft Water vapor

Air supply

The above formula is for complete combustion. Usually excess air is needed to get complete combustion as greater mixing occurs and more of the fuel particles will make contact with the oxygen. Incomplete combustion reduces the amount of heat that is obtained and increases the amount of pollution. Normally furnaces and boilers are operated with about 50% excess air. A common problem in many newer greenhouses is that they are very tight. As the heater operates, oxygen is used and combustion efficiency decreases unless makeup air is available. A free air inlet of at least 1 sq in/1000 Btu/hr input is needed. Each winter there are several instances of tight greenhouses that have frozen up when the heaters were starved for air and the heat output decreased.

Carbon dioxide

One of the byproducts of combustion is carbon dioxide which can enhance plant growth. One of the problems is that carbon dioxide is most effective when light levels are the highest during the day and the carbon dioxide is mainly produced at night when the heater operates the most.

Water vapor

Another byproduct is water vapor. This is added to the greenhouse at night when moisture levels are already high and can condense out on the cold glazing surfaces and drip on the plants. Increased moisture levels can cause increased incidence of disease problems including fungi, blight and molds.How much water do we get? If we take a 30' x 100' double poly greenhouse and maintain inside temperature at 60 ° F on a 0 ° F night for a 12 hour period, heating with unvented propane or kerosene heaters would add about 22 gallons of moisture to the air and heating with natural gas would add about 16 gallons. If the heaters were vented, the moisture would have been exhausted outside along with the flue gases. This moisture added to the normal transpiration and evaporation could keep the relative humidity well above 90%.

Other combustion products

All fuels contain traces of sulfur, some more than others depending on its source. During combustion sulfur in the fuel is combined with oxygen to form sulfur dioxide. Levels as low a ½ part per million (ppm) can cause injury on some plants. Once the sulfur dioxide enters the plant through the stomates, it reacts with water to produce sulfuric acid that will cause leaf burn, flecking and general chlorosis. Tomatoes and white petunias are very sensitive to this and will show signs in as little as one hour. They therefore make good indicator plants.Ethylene gas is another pollutant formed during combustion. It can also be formed from ripening or rotting plant materials. Levels as low as 0.01 ppm can create symptoms such as malformed leaves and flowers, stunted growth, bud abcission, epinasty and flower senescence. Levels are usually highest near the heater and can be diluted by air circulation.Care should taken if you install unvented heaters. Be sure to have an adequate makeup air supply and provide frequent maintenance. Use indicator plants near heaters or commercially available indicator tubes to warn of excess levels of pollutants.

Good article, but it makes the assumption that the lights are only on in the daylight hours. I run mine at night when it's cooler to let the cooler night temps help offset the heat of the 600's.

doobs did you ever get that?
Last week I got two envelopes.
One was tore open in the corner and empty, the other had a small pile of crushed beans in the bottom.
:-(
I think something happened when they were being whizzed through the mail system. Hoping it wasn't on purpose by someone.
Was really looking forward to trying them out, but the mail was too rough on them this time.
But thanks for trying! :-)

Oh, and we had about 15 kids stop in for candy last night.
Which is about 10 more kids than the previous 10 years of Halloween combined.
And we didn't have decorations to lure them to their tooth cavities, so next year we'll be more prepared & festive.

I imagine you'd be good at dressing up and scaring the kids doob.

Maybe next year I do a haunted "Clerks" theme.
Big old white bed sheet over the window with "I ASSURE YOU WE'RE HAUNTED" scrawled on it in blood.
Have Dante hung by his neck from the tree out front.
Dead old guy with a woody on a gurney under a sheet in the driveway.
Smokers' lungs on a platter by the door.
Jay as a vampire, Silent Bob as Frankenstein's monster.
Cranky old ghoul (name is "WINOWSKI", and I wanted to watch a movie tonight) wandering around asking everyone if they've seen his keys.
The Jizz Mopper as himself.
And me dressed up as Zombie Randall, ready to lay some truth and drop some knowledge on the chillin's and anyone brave enough to come to the door with their hand out.

Thanx for the likes and +rep folks. I can't wait for these cuttings to get big enough to throw in flower. Looking forward to a full tent with the 2 600's blasting their ass.
Gonna try and run 4 trays 5 plants per tray and see how they do. Was gonna run more plants but kinda worried bout crowding and light penetration.

The article is about greenhouse heaters. Personally I would never run an unvented gas burner inside a house. Dont care how clean they burn. Electric heaters, and fireplaces for me.

Gas burners is how a co2 generator operates.This is also why i think a sealed room should be vented with fresh air change over a few times at least a day.But burning open flames in a home. even with a gas cook stove is done every day and no one is dropping dead. I am however talking about a co2 generator used to add heat with. not a gas heater.This will probably not replace the electric heater but add to it.
