If your room is dialed in perfectly and you know what you're doing, CO2 will improve your yields. I'm not sure you'll get these results with the biobags, but certainly with tanks or burners. Most people don't know how to run CO2 and get sub-optimal results. Hope this helps

Yeah I thought that no matter what you want more CO2, so having only a restaurant tank but no regulator then flooding my room til I couldn't breathe,lol, and figured it had to help. It only cost about a buck /day doing that (totally scientific) method. Pretty sure it helped only marginally, so every other way 'd be better. Imo it can't possibly hurt. You'll always gain at least what's spent. But 2get the breakeven, 1gram more/plant vs. getting 30% more/plant with timers, regulated with fresh air exchanges, etc is where ppm 02/co2 requires perfection. But my $50/mo vs. $300system+$35/mo(the right way) is usually considered.
. maybe the best question is "if I'm already giving my growspace adequate fresh air cycles, for $300, am I better off supplementing with side lighting or adding co2 system? Because unless you already have optimized lighting u might b better spending that $300 on lights

I doo co2 on average 3000 ppm in veg it makes an insane difference can grow it 4 inches a day with hortilux 7200 mh . im currently doing an experiment one room no co2 other room with co2 so far they look the same . ive never done it with out co2 lol

I thought 1500 ppm's was the the max you would want to run? I've dabbled but no expert but my understanding is 1200 is optimal with lights on.

I have my linear controller set for 1200 although not using it right now, things are complicated enough for being a hobby lol.

yes indeed the 3000 ppm sounds high ! but in fact I did start it at 1200 like the old books say . I started to crank it up slowly day after day until I finally maxed out a my control highest ppm . yes they like the higher co2 indeed in veg I have it 85f and its about 60 wet strong 1000 watt lighting can grow it faster then any where in the world under this condition . in my opinion and experience the 1200 or 1500 ppm is bull shit . slowly crank it up . I have a burner . if you have a bottle it might be wasting your money .

How are you controlling the burner? Is it just a relay that turns it on and off, and at 3000ppm are you still getting proper combustion?

yes it is burning correctly . I am using co2 a controller

3000 ppm is not that high you can chill in the room and be fine . I would not take a nap though .

So I will be growing out of a 40' x 8' x 8.5' shipping container in the very near future and wanted to know about CO2? I would like this to be completely automated and produce 1000ppm when lights are on. How much will this cost me? I can install it myself. I'm not trying to go cheap and have it not work properly. This is a commercial grow.

It depends on lots but you would be running a generator at that size as opposed to bottles. There are lots of charts available that will tell you what you need re amounts of CO2. The extra cost of running a sealed room with cooling, sealed lighting, ext.. If your going to run a 40 x 8 room you've got lots to look into and CO2 will be but a small part. Also pretty sure with that size you will need a way to distribute the gas evenly so keep that in mind as well.

I plan on keeping a video log and documenting the entire grow! I am very excited

^^^^^ yes it will be a very cool project. That's my next grow room, just spray foam the inside and instant grow area 
. Only a half size container though lol.

There is a company here in colorado that sells these units ready to grow immediately but they're $44,000 for 320 sq feet. I figure i can build one myself for much cheaper than that.

^^^^ ya I've seen a couple of prebuilts, their pretty cool. I'm all for DIY. The infrastructure would take some pre-planning, I was thinking of pre-studding and spray foam the shit out of it, then plywood painted flat white, My building now only has studs covers with bubble wrap insulation to fasten stuff to it and should have cladded it with plywood to be able to mount lights, controls, etc. it's a real pain in the ass now lol.

I've been using co2 throughout my grow. I'm just now switching into flower today after flowering for seven weeks. I started running my ppm at 1250 but upped them to 1500 as they got bigger. They say 1500ppms is the most co2 a plant can uptake. I did a lot of topping my first few weeks of veg and then I let them bush out. I grow organic and make my own soil. Once the rootball filled out the pot I get about two inches of growth everyday. I'd say co2 supplementation is where it's at! I wouldn't bother with the bags though unless you're in a small closet grow. The tank is worth the set up costs and I get mine refilled for $10.

And even more telling, here's a blue cheese after I clipped the wrong stem and left it looking puny on January 15th.

Co2 is where it's at! You can follow my grow journal if you want see how these heavenly maidens bloom.
