That minigen wouldn't be able to come close to producing the amount of CO2 I need - plus, I have a hose hookup in the garage, so I just need to drill a little 3/4" hole through the exterior wall and run a little PVC to drain through and I'm golden - all the CO2 I want with none (well, very little) of the heat associated with it.What up Bob. I would still seriously consider the MiniGen. The Hydrogen requires water to operate. The mini its optional. The Mini also produces much less heat than the Hydrogen(Like 1/10) and is much easier to cool. If you give them a call though and tell them your garden dimensions, they'll tell you what one you should use for sure. And the split a/c's suck out co2 for sure, but not like crazy. My minigen is right next to my portable a/c(worst possible spot for getting sucked out)and when it kicks on, the MiniGen keeps it at 1350ppm the whole time its running and then shoots back up to 1500ppm about 30sec after the a/c goes out. And I know this sounds retarded, but if you can build a table/shelf sturdy enough to set your portable a/c on it will sick out far less co2 and will cool your room more efficiently. So I thought I'd give you another idea to dwell on. They use the same technique down south when they run the ducts in houses and place them high up on walls so that the cold air will drop thought the whole room instead of pooling down low and having to build its way up. Not sure on the ceiling, I would say drywall, but obviously thats out. As far as insulation, I would see which one you can get the most of with the highest R value. The higher the R the better it insulates. The better you insulate, the more likely you'll be able to keep your temps under control. I feel like Im forgetting something. Oh, after you did your gas piping did you leak test? If not, just take some dish soap and mix it with water in a spray bottle and spray all the joints you worked on. If it bubbles anywhere, thats a leak. And one last positive not to make you feel better about your work, Natural gas burns about 1200F cooler than propane, so for the same amount of co2 produced, half the amount of heat is produced. Just a fun fact for ya.
Yeah, I emailed the dude over there first thing this morning to inquire about a NG Hydrogen and he said that they stopped making them, so that pretty much made up my mind.Why the switch back again?
I haven't heard of any issues with using HW heaters (don't know about NG model), but I know HI discontinued (still sell a kit though) their NG model due to low pressure issues in Western states (CA & CO primarily).
Even when battery powered, the D Cells last for months. Probably would be no big thing to swap in a low voltage power supply.
I like options, what can I say? :ridinghorse: (not sure how that smiley relates, but it made me laugh when I saw it)Haha
Yeah, I've noticed!
Granger has some great meters we use in the lighting biz here in Coloradoim just stoked to see u get this shit up and runnin man. i never invested in a light meter so i cant rec one to u but im startin to think its time to get one. i hate guesswork and cant do controlled experiements with guesswork. lol. plz share ur findings or PM me if u dont mind. the garage does sound like a better solution. ill b lurkin...
Yeah, talked about it in the second paragraph - not a biggie that you missed it; I know I type too much, but I like to treat these as a journal that I can review. It was pretty funny when I was telling the guy in Home Depot how I almost set the 2x4 on fire with it.That table saw looks like a 'chop saw'... Good for pvc, brick, etc. Not really what you want.
Use 1/4" drywall for the ceilings. Not as heavy so 24" centers are no problem.
Can you just staple 2 sheets of panda around the garage door? Might need to nail up some headers/footers to hold it.
