Natural gas is usually free or extremely cheap from the gas company if you have a hookup. Otherwise run propane. As far as I know.
It's the flame that creates co2 not the gas. As a flame burns , every oxygen molecule a flame uses, that oxygen molecule is replaced by 2 carbon dioxide molecules.

I planned on natural gas anyways. I already have line to tap into.
Ive always used #50 tanks and tired of filling every 3 weeks.
I also wanna have room to expand, right now im going from 4 to 8kw of lights. Rooms 10x 25 or so.
How big of a burner would you suggest? I dont wanna upgrade if i double or triple space or lights to 16 or 24.

no its not you were right Propane has more BTU
Natural gas is made up of several gases including propane, butane, ethane and mostly consists of methane. While propane is a part of natural gas in its raw state, it is a hydrocarbon separated from the other gases at gas processing facilities.
While propane is sold and delivered in gallons, it can easily be converted to cubic feet, which is how natural gas is measured for delivery. The cubic foot unit of measurement pertains to both natural gas and propane in their vapor forms. Provided that 1 cubic foot of propane contains 2,516 BTU and 1 cubic foot of natural gas contains 1,030 BTU, it is accurate to say that propane contains over twice the usable energy but breaking it down to dollars n cents this is why many just go natural gas cause its half the cost

Maybe I am and the info in the link is wrong?
I could swear my bbq is hotter with propane..lol

There is a misconception that natural gas (NG) does not burn as hot as propane (LP). The truth is that the flame temperatures of NG and LP are both approximately 3,560°F. However, it takes approximately 2.5 times the volume of NG as it does LP (as a gas, not the bottled liquid) to produce the same amount of heat from the same appliance. This is why NG requires larger piping and larger burner orifices.

Look on Ebay for portable water heaters......get one that plugs in if you can.....anyway they are internally the same as Next Gen Co2 generators and for about $120.00 ! I use one in a 12x24 and it jumps the ppm to 1k in about 3 min "on" time from ambient......I use a chiller with a 55 gallon drum with 45gal of water in it with direct Co2 ppm sensor plug in.....The ppm drops from my set Point. The pump is switched on from the sensor and the Gen and chiller fire when the water passes through it.....3 min tops and it clicks back off at 1.3k ppm
The one I have takes D cell batteries to ignite the burners.....haven't had to change them yet...

Keep in mind your going to want to be sure you have the right amount of dehumidifier as they put plenty of water into the air in humidity from H20 released from burning the gas..

And you don't have a tank of it. It's piped in at a steady pressure delivering a constant volume. Propane sucks if you are dependent on it. Especially in cold country. Your natural gas bill can wait a bit if you are broke. The propane tank goes to inadequate pressure and you do not have gas.

Plan on a dehumidifier as well. Gas burning creates humidity. Electric heat does just the opposite and dries air.

A "K" size cylinder of CO2 from a welding supply, along with a cheap regulator, is cheaper and delivers almost pure CO2. A lot of it. Run a plastic line, plugged at the free end, and run it over your plants. Melt holes in it with hot paper clips if you really are on a budget. CO2 sinks in room air as it is heavier than oxygen. This "Rains" CO2 down when you want it. Shut the valve off when you don't. And no humidity. Bud mold or rot sucks.

After running propane for a year, I would like to upgrade to NG.. Cause I hate hauling cylinders.
I liked using the uncooled versions of the co2 generators, they create quite a bit of waste heat and water vapor so this could be an advantage to some of us running greenhouses in cooler climates needing heat and having cool dry air comming in from the outside.
If you need the heat, try to find a model with a pilot light, if you dont need the heat get the ones with an electronic ignition.If heat is a problem, get a water cooled one.
