NEED HELP WITH Co2 Ideas ASAP

HI i am building a gow box 4 ft wide, 3 ft deep, and 6 ft tall i am putting a 400 watt metal halide and four 75 watt floursents lining the bottom and lower sides for more light. I will be running a fan to cool the light a fresh air intake fan and a stale air exhaust fan one more fan just circulating air. NOW what i need your help with is i want to do this top of the line so what will a Co2 do for me and how do i go about setting it up pics will be helpful what is the average set up cost not a cheap one THANKS FOR LOOKING

Go to U-tube and watch the vid I GROW CHRONIC it will show u a way to set up what I would think to be a perfect setup for what u have going. It will cost u a ton of money though. There are homemade methods as well, just google it

Read this will answer co2 question Growing cannabis ( marijuana ) with C02

The basic CO2 tank system looks like this:
20 lb tank $99
Regulator $149
Timer or controller $10-125
Fill up $15-20
Worst case = $395 for CO2 tank setup synced to a exhaust fan with a thermostat.

I've never personally grown with CO2, but I've helped out on a couple grows that have. I'll say this: if you're going with a tank-based system, you will want *TWO* tanks. It makes life a lot easier to be able to refill the tank not in use when convenient, and then have it ready to swap when the other runs dry.

I bought a nice co2 setup with cycle timer etc and a brand new alum tank for $350 at a local hydro store...I'm scouring craigslist actually looking for a few spare tanks=)...

I have pics of the cycle timer and such in my grow journal below

thanks alot guys for your info i just got a 40 lb Co2 tank from a fast food pop machine. for free so now i just need timer and regulator RIGHT? i will watch the videos and thanks againe for looking.

try with out co2. it can only complicate thing for a new grower. get a few grows under you belt and then try some co2.

there are regulator kits available. they have the timer included as well as the hosing to loop around your growing area. i have this KIT. works well and i'm impressed with the results. however, i wouldn't recommend it for first, second or 3rd time grower. but if you have the cash, go for it.

Did you really use that HIGH TECH GARDEN SUPPLY i was thinking about using them but wasent sure if i was going to get ripped off or not. The co2 set up you showed me was exactly what i was looking for think i should order from them i live in Mount Clemens, Michigan

that kits looks like a PITA ass check the first page on my grow journal thread mines seems 100x easier to adjustunless Im seeing things wrong..
