Need Co2 Advice

Hi all,

I am a medical grower out here in Colorado, things are really getting crazy out here, there are now more dispensaries in Denver than Starbucks (no joke). I just got setup in my 2000sq foot warehouse, I have a 900 sq foot bloom room with 16 foot ceilings, and I am not sure how I am going to provide ample Co2. I dont want to buy a propane burning setup, my lease bans the use of flammable gasses. I have a natural gas heater hanging from the ceiling, with a 4" duct that vents the gasses out the roof. I would like to take advantage of this, but do not want to overdo the Co2, or have nasty fumes mess with my plants. My idea is to put in a 4" Y off the heater with a dackdraft damper, and then a 4" blower that would activate based up timing or controlled by a Co2 meter. It is cold here and the heater runs relatively often. Is this a Kosher concept?

2nd Idea- There is a microbrewery 40 feet away from me, I could run a 1/2" line from their still that emit Co2 right into my place, this sounds way to awesome, but I may run the risk of getting all the nasty molds or whatever may be coming from the still. Anyone ever tried getting C02 from a beer brew?

negotiate the term of your lease

unless you're gonna seal the room, don't use co2, it would be wasted.

use a co2 controller hooked up to exhaust fans so if ur heater does provide enough and/or too much ur exhaust can switch on and dump it back down to a safe level..
but would ur heater provide enough co2 for optimal levels? i think not bcos ur in a warehouse right

You have a natural gas line? Buy a HydroGen generator and chiller. Runs on NG with little heat. You'll need a controller for everything anyway if it's a closed loop system.

Look into a Harvest Master controller for a setup that large.

thanks smokingmaster, I think you have the right idea.

I didn't think the CO2 from a brewery was vented. Thought it got stuck in the beer (hence the bubbles)

yep it's insane in denver..

you should try to tap into that natural gas line, buy something similar to this

The brewing process gives off C02 naturally, and some brewers capture that for future bottling, but the CO2 has to be run through a machine to be 'sanitized' and these small time brewers dont have the machine, so they seep out a slow steady of C02 from the brew.

Due to the fact that the bottlers have to sanitize it first, makes me concerned about airborn fungus or mold or whatever spores.

I suppose i could run the line through a homemade box and bubble the mixture through a Hydrogen peroxide or alcohol mixture to sanitize it tho......
